Quick Answer — The Freesky Warrior Pro M-530 is a full-suspension fat-tire e-bike with a hub motor in each wheel, 240 N·m of torque and one 48 V 30 Ah pack, 1,440 Wh. On flat pavement a 180 lb rider gets a computed 80 miles from a full charge at 15 mph on the throttle.

At 20 mph on the throttle the same charge lasts about 58 miles, and with easy pedaling at 15 mph it stretches to 122. Freesky's U.S. page rated it at 60 to 95 miles on one motor and 40 to 60 on two.

The bike is sold out on our store and Freesky's U.S. page for it was not being served on October 14, 2026, so every Freesky figure below carries the date of the page, post or document it was read from.

The Warrior Pro was sold out on our store on October 14, 2026, and we do not sell what we cannot ship. Our Freesky brand page lists the Freesky models we carry, and every e-bike we sell ships free within the contiguous United States. If you own a Warrior Pro, the parts we sell for it were orderable that day, and an email to support@redtailebikes.com puts you on the list for the bike itself.

How we verified this Freesky Warrior Pro review

Every figure here was read on October 14, 2026 from Freesky's own pages for the Warrior Pro M-530: its U.S. page as the Internet Archive captured it on October 10, 2025, five earlier captures behind the history tables, its Canada and UK store pages, the user manual and the UL 2849 certificate Freesky publishes, our listing, and the statutes quoted in the class section.

The range and fit figures are computed, and each section's formula names its inputs and where they come from.

This review is specification-verified: each number is Freesky's, a statute's, or arithmetic shown on this page. Where Freesky's pages disagree, the page prints both figures with their dates and never picks one. We sell Freesky e-bikes, so give the red flags the weight you give the green ones.

Can you still buy the Warrior Pro?

Not from us today. All four colorways on our listing, Black, Blue-gray, Green and Camouflage, read sold out on October 14, 2026, and the listing stays up so its address keeps working. We do not take an order we cannot ship.

Freesky's U.S. store was not serving a page for it either. A check run as a U.S. shopper on October 14, 2026 got "page not found" (HTTP 404) at the address where the Warrior Pro's page stood, in the same minute that another model's page on the same store loaded; the store's own listing, sitemap and search did not show the model.

The Internet Archive's newest capture of that address, taken August 31, 2026, is a 404 as well. Freesky's U.S. product feed named a Warrior Pro M-530 record on both days, but not the same record. The one read on October 13, 2026 had been created on November 20, 2024 and was priced at $1,749.

On October 14 the feed gave that record another model's name and gave the Warrior Pro name to a record created on August 21, 2026, priced at $1,999 (the price table below has both readings). We could not establish why the page is not served, and Freesky has not said.

Freesky has not said the model is over. The company's news feed, read in full on the same day, holds 30 posts from April 22 to September 22, 2026. Thirty-two paragraphs in them name the Warrior Pro, and none says it is sold out, discontinued, retired or replaced. Its Canada and UK stores still carry a page for it, with a newer specification that the next section sets beside the U.S. one.

What that leaves you with depends on where you stand:

Every row is a figure Freesky printed on the date shown, under the name Warrior Pro M-530 in its U.S. listing or feed. The last two rows come from two different records, as described above, and the page for the second was not being served; none of these is an offer, and ours is sold out.

The specifications, each with its date

Freesky's U.S. page and its other stores describe the Warrior Pro M-530 in slightly different words, and the U.S. page is the older of the two. The table prints each side in the maker's own words, so you can match the label on your bike to the column that describes it.

What changed on the U.S. page, capture by capture. Freesky's page for the bike carries its own history, and the figures that matter most moved more than once:

Each cell is what the captured page printed on that date. Freesky's blog post of March 20, 2025 still described a 48V 25Ah pack with 50–85 miles on one motor, and its post of September 1, 2025 gave 60–120 miles on one motor.

The label on your bike settles which row is yours. The pack carries its own rating, and Freesky's own instruction for a replacement battery, motor or fork is to order by model and serial number; the parts section quotes it.

How the two sets of photographs differ. Freesky's studio photographs of the Black bike came in two sets, and they show different equipment. The file named 530-black-02.png, on the page archived October 10, 2025, shows the bike without a rear rack or mudguards, and the set in Freesky's product record of March 5, 2026 shows both, plus a kickstand.

The Canada page's "What You'll Receive" list names the rack and the mudguards, and the manual's box list names neither.

A full-suspension fat-tire bike with a motor in each wheel

Freesky describes the Warrior Pro as a "Dual-motor all terrain ebike" and puts its promise in one sentence on its U.S. page: "Powered by dual motors delivering a combined 4000W peak, it generates 240 N·m of torque (120 N·m per motor) for exceptional acceleration and climbing power."

In plain terms, that is a hub motor in the front wheel and another in the rear, an aluminum frame with a fork and a rear shock, 26 × 4-inch fat tires and one removable pack.

From the front three-quarter: the headlight on the fork crown and the front wheel's hub motor, one of the bike's two.

Freesky's own 2026 writing uses the phrase buyers search for. Its June 12, 2026 post on motor types says the Warrior Pro's "dual geared hub motors" deliver "powerful all-wheel-drive performance capable of handling steep climbs, loose surfaces, and rugged terrain." The word geared matters later: a geared hub motor is the kind the range model uses as its stand-in.

From behind: the rack, the rear mudguard, the rear wheel's hub motor and the shock above the chainstay.

A rider drives both wheels only when both motors are switched on. Freesky's page says the motors are "independently controlled via a handle button," and its Canada and UK pages say the bike has "switchable rear-wheel drive and dual-motor drive modes."

The manual frames the first ride this way on page 7: "On flat terrain, in a low gear (1 or 2), and using rear-wheel drive only, most riders can begin pedaling with pedal assist set to level 0 or 1."

In Freesky's post of September 1, 2025, "rear motor mode" is for efficiency and "dual motor mode" for "maximum traction and climbing power." So the machine is two bikes in one frame: a one-motor bike for range and a two-motor bike for traction and climbing.

Will the Warrior Pro fit you?

On Freesky's listed seat range, the post reaches the fit formula's saddle height for 97 of every 100 riders at 5'5" and 63 of 100 at 5'8"; at 5'10" the count is 21 of 100, and at 6'0" it is 4 of 100. On the saddle lines Freesky draws, the same four heights count 15, 74, 95 and 94 of 100, so the label and the drawing sit about four inches apart, and this section prints both.

Across every height in the tables, the median rider sits within 16 to 21 degrees of upright, and with the back fully relaxed the hands carry 16 to 19 percent of body weight.

The model puts the 6,068 bodies the US Army measured for its 2012 survey onto Freesky's own geometry and sets each saddle at 109% of inseam. Three steps take you from the tables to your own answer:

  1. Get your inseam. In bare feet, with your back to a wall, pull a hardcover book up between your legs as a saddle would sit, and measure from the floor to the book's top edge.
  2. Find your height in the tables below and see whether your inseam falls inside that row's typical range. From an inseam of 33.0 inches up, the formula asks for more saddle height than Freesky's labeled 40 inches provides.
  3. Settle it on the bike, with the knee and heel checks at the end of this section.

Freesky prints one frame, two rider windows and an inseam range, and it draws the saddle higher than it labels it. Its archived U.S. page gives a rider window of 5'5" to 6'3"; its Canada and UK pages, read the same day, give 5'5" to 6'8" and add an inseam range of 27 to 35 inches. The table sets each published figure beside what its own drawing measures.

What Freesky publishes Its figure On its drawing
Rider height 5'5" to 6'3" on the U.S. page; 5'5" to 6'8" on the Canada and UK pages not drawn
Inseam none on the U.S. page; 27 to 35 in on the Canada and UK pages not drawn
Seat height, lowest 35 in 39.0 in
Seat height, highest 40 in 43.6 in
Reach 17.7 in 21.0 in
Standover 27.1 in 27.1 in

Freesky's geometry drawing of the Warrior Pro with the seat height, reach, total height, standover height, wheel diameter, wheelbase and total length marked

The drawing, scaled to Freesky's published 49-inch wheelbase. The total length, the total height, the standover line, the wheel diameter and the wheelbase agree with the tables to within 3 percent; both seat lines and the reach measure longer than their labels.

Will the saddle go high enough for me?

Through 5'7" the post reaches the formula's height for 81 of 100 riders or more; at 5'8" it is 63, at 5'9" it is 45, and above that most riders run out of post on the labeled range. The formula puts the top of the saddle at 109% of your inseam, measured from the pedal axle (Peveler et al., 2005), and published work accepts settings as low as 106% (Ferrer-Roca et al., 2012).

The height off the floor then depends on the 12.3-inch crank axle, the 170 mm cranks Freesky lists for the Warrior Pro in its parts store, and a seat post angled at 71.3°, which is read from Freesky's drawing because Freesky publishes none.

6'4" 36.3–39.1 in 44.8 in 9 of 100 46 of 100

The same bodies against the saddle lines Freesky draws, 39.05 to 43.59 inches at the wheelbase scale. A rider counted at 109% would meet the formula only between those two lines.

The label's 40 inches and the drawing's 43.6 cannot both describe one post. A rider at 6'0" is among the labeled range's 4 of 100 and the drawing's 94 of 100, and a rider at 5'5" sits at the opposite end of the same disagreement, 97 against 15.

The manual settles the real top for your bike: it tells you to slide the post in or out of the seat tube and "not to raise the seat post beyond the minimum insertion mark on the seat post tube" (page 18).

Freesky's inseam range on its Canada and UK pages runs from 27 to 35 inches. On the labeled post, the formula's saddle meets the top of the post at a 33.0-inch inseam (33.9 at 106%) and the bottom at 28.2; on the drawn lines the bottom meets it at 32.1 and the top at 36.5.

Above its top inseam, the saddle stays at the top of its post and your knee bends further at the bottom of each stroke than the formula would set it.

Can I put a foot down at a stop?

Yes: for 95 of every 100 riders at each height in the table, the 27.1 inches Freesky gives as standover clears by 2.0 inches at 5'4", the shortest row, and by 9.2 at 6'4". The frame has a top tube you step over, and the margin grows with your height, so the shortest riders in or just under the window have the least room to straddle it.

Your height Typical inseam Clearance at 27.1 in At 27.3 in
5'4" 30.5 in 2.0 in 1.8 in
5'5" 31.0 in 2.6 in 2.4 in
5'6" 31.7 in 3.1 in 2.9 in
5'7" 32.2 in 3.6 in 3.4 in
5'8" 32.6 in 4.0 in 3.8 in
5'9" 33.1 in 4.6 in 4.4 in
5'10" 33.8 in 5.1 in 4.9 in
5'11" 34.3 in 5.8 in 5.6 in
6'0" 34.9 in 6.1 in 5.9 in
6'1" 35.6 in 6.8 in 6.6 in
6'2" 36.0 in 7.2 in 7.0 in
6'3" 36.6 in 8.2 in 8.0 in
6'4" 37.6 in 9.2 in 9.0 in

Barefoot inseam minus each figure: 27.1 inches from Freesky's Geometry table and 27.3 measured at the standover line's column on its drawing at the wheelbase scale. Each cell is the clearance that 95 of 100 riders at that height have or exceed.

Will I feel cramped, or stretched?

Neither: the median rider sits 16 to 21 degrees from upright, because the grips sit 29.3 to 30.8 inches above the crank axle and 15.3 to 17.3 inches ahead of it. In a study of twenty recreational cyclists asked to rank three trunk positions, the most upright was the one they found most comfortable (Priego Quesada et al., 2017).

Each angle below is the smallest lean at which a straight arm still reaches the grip from the sit-bone position, worked out from that body's measured torso and arm.

Your height Lean from upright, median rider Across saddle and grip positions
5'4" 20° 13–25°
5'5" 20° 14–26°
5'6" 20° 14–26°
5'7" 21° 15–26°
5'8" 21° 15–26°
5'9" 21° 15–26°

6'2" 18° 13–23°
6'3" 18° 13–23°
6'4" 16° 11–22°

Trunk lean from vertical for the middle rider at each height; the spread covers where the sit bones rest on the saddle and the length of the grip on Freesky's drawing.

How much weight goes through my wrists?

At most 16 to 19 percent of your body weight, with the back fully relaxed. In a lab study, 10 road racers pedaling with their hands on the hoods put 15% of their weight through the bars (Carahalios, 2015); the Warrior Pro's relaxed-back ceiling sits a little above that figure at most heights, and your back muscles carry part of it in practice.

A forward lean moves load onto the heel of the hand over the ulnar nerve, and in 36 riders that pressure was highest in the most stretched-out hand position (Slane et al., 2011). Padded gloves cut the palm pressure by 10 to 28% in the same study.

Your height Share of your weight, back relaxed Median rider's weight On each hand
5'4" 17% (14–20%) 147 lb about 13 lb
5'5" 18% (15–20%) 157 lb about 14 lb
5'6" 18% (15–20%) 166 lb about 15 lb
5'7" 18% (15–20%) 172 lb about 16 lb
5'8" 18% (16–20%) 179 lb about 16 lb
5'9" 19% (16–21%) 185 lb about 17 lb
5'10" 19% (16–21%) 192 lb about 18 lb
5'11" 18% (16–20%) 196 lb about 18 lb
6'0" 18% (15–20%) 204 lb about 18 lb
6'1" 18% (15–20%) 206 lb about 18 lb
6'2" 17% (15–20%) 216 lb about 18 lb
6'3" 18% (15–20%) 227 lb about 19 lb
6'4" 16% (13–19%) 220 lb about 17 lb

The most the hands carry with a relaxed back, computed from each body's segment weights (Clauser et al., 1969) at the survey's median weight for that height; the range spans the saddle and grip positions.

How do I set the saddle when it arrives?

Set it so your knee still bends 25 to 35 degrees with the pedal at the bottom (Peveler et al., 2007). The manual gives the same test with the ball of the foot on the low pedal: "Your leg should be almost fully extended (but not locked) with a slight bend at the knee" (page 18).

With the heel on the low pedal and the saddle raised until that leg just straightens, the heel method put 70% of 19 cyclists in range, more than either inseam formula did (Peveler et al., 2005). The manual adds two limits: keep the post below its minimum insertion mark, and "do not exceed the limit markings on the seat rail" when you slide the saddle fore and aft (page 19).

How we computed fit

Three rules drive every table here: the saddle's top sits 1.09 × inseam above the pedal axle, the lean is the smallest trunk angle at which a straight arm still reaches the grip, and the load on the hands is the weight of the head, trunk and arms times that lean's lever arm, divided by the reach to the grip.

Take a 5'8" rider with the median 32.6-inch inseam: the formula needs 35.6 inches from the pedal, which is 28.9 inches from the crank axle (88.3% of inseam gives 28.8), a floor-to-saddle height of 39.6 inches, just under the 40-inch top of the labeled post.

Every length is scaled from the published 49-inch wheelbase, measured between the axle centers. The model keeps Freesky's labeled seat range as its answer and prints the drawn lines beside it, because five lengths agree with the tables and both seat lines and the reach do not.

Two hub motors, 2,000 W peak each

Freesky prints a peak for each motor, 2,000 W, with 4,000 W and 240 N·m combined; the stand-in motor this page's range model uses is rated 1,000 W, so read the peak as a ceiling and the range tables as energy. Freesky's page calls them "2000W + 2000W Brushless Peak Motors" and its headline strip reads "Peak Power 4000W" and "Torque 240 N·m".

Its June 12, 2026 post describes them as "dual geared hub motors producing up to 120Nm of torque each."

The front end of the Freesky Warrior Pro: the front hub motor, the disc rotor and caliper, the fork and the front mudguard, with a rider's leg and sneaker in a spray of sand

Freesky's own close-up of the front end: the front hub motor, the rotor and caliper, the fork and the front mudguard.

A peak is what a motor may draw for a short burst, and a rated figure is what it can hold. Freesky's page printed "1000W+1000W Dual Brushless Motors" through its capture of August 3, 2025 and "2000W + 2000W Brushless Peak Motors" in its capture of October 10, 2025, so the label on your own bike is the quickest way to know which pair it carries. The class section shows why the difference matters for a watt limit.

To price energy, the model needs a motor with published figures, and it takes Bafang's RM G0H0 geared hub, a 48 V motor the workbook rates at 1,000 W, with 510 rpm unloaded, 426 rpm at the rated point, an efficiency of "≥ 80" percent and a maximum torque of 90 N·m.

Two of them share the load evenly. On Freesky's 29.3-inch wheel those speeds come to 44.5 mph unloaded and 37.1 at the rated point, which is why the throttle table stops at 34 mph.

The controller is printed three ways. The U.S. page of October 10, 2025 lists "48V/30A", the UK page of October 14, 2026 lists "48V/22A+22A", the Canada page prints no controller row, and the capture of September 18, 2024 lists two controllers of 48V/22A. Freesky's parts store sells the two motors as separate parts, a front motor and a rear motor, and the parts section lists both.

The controls, in Freesky's words. The U.S. page prints a thumb throttle, pedal assist at levels 0 to 5 and a "Speed Sensor"; its other stores print a thumb throttle, the same six levels and a "Cadence Sensor".

The manual describes the throttle as "rotating the throttle backward toward the rider" (page 22) and says to use it only when you are on the bike. Both motors answer to a button on the handlebar, which Freesky's page calls "independently controlled via a handle button."

One 48 V 30 Ah pack, 1,440 Wh

By Freesky's figures the pack is 48 V × 30 Ah, which is 1,440 watt-hours (Wh), and at the 47.19 V rating on the bike's UL 2849 certificate it is 1,416 Wh, 1.7% less.

The cells are printed two ways: "SAMSUNG Cell" on the U.S. page and in Freesky's posts of May 18 and June 12, 2026, "LG Cell" with an IPX7 rating on the Canada and UK pages read October 14, 2026. The energy is the same in both; the label on the pack says which you have.

The vented panel and the Freesky wordmark on the down tube of the Warrior Pro, with the rear shock out of focus behind it

Freesky's own photograph of the down tube, where the manual puts the pack ("Battery on Downtube", page 11).

It ships switched off. The manual's note on page 11 reads: "In order to protect the battery and increase battery safety, the battery is turned off by default. Please take out the battery and press the switch button before use." The pack comes out with the key (turn it counterclockwise to unlock, page 10) and goes back in the same way, and the bike's own power comes on afterward by NFC or by password (page 22).

Charging is a 3 A job. The UL 2849 certificate rates the charger at 54.6 V DC and 3.0 A output, which is up to 163.8 W, so 1,440 Wh takes at least 8.8 hours before losses and the charger's taper; Freesky's page says "10 hours" and its post of September 1, 2025 says "8–10 hours".

The manual limits the pack to 0 °C to 40 °C (32 °F to 104 °F) in use, in storage and on the charger (pages 5 and 12), and says: "Charging of the eBike shall only be performed with the manufacturer's recommended charger" (page 12).

Freesky's own charging guide of June 12, 2026 says: "If full range is not needed, charging to 80-90% can reduce thermal and chemical stress." That is why every range table here has an 80% column.

The warranty on the pack, as Freesky's U.S. page printed it: 18 months on the motor, the battery and the controller and 12 months on other parts, for the original owner only, and "not transferable." Within three months a quality-issue replacement is free; from four to twelve months Freesky asks 50% of the shipping and from thirteen to eighteen months all of it. A replacement pack is one of the parts we sell.

How far the Warrior Pro goes on one charge

A 180 lb rider on level pavement can expect about 80 miles from a full pack at 15 mph on the throttle, 58 at 20 mph, and 122 at 15 mph with easy pedaling. An 8% grade at 10 mph on the throttle brings the same charge down to 14 miles with both motors on, and 10 on one.

Three steps turn these tables into your figure:

  1. Start with the speed and effort you expect to ride, in the first two tables.
  2. Set aside 171 to 224 Wh of the pack for every 1,000 feet you climb at 10 mph on the throttle, on 4 to 10% grades with both motors on, or 228 to 343 on one motor (the hills table).
  3. Correct for your load and the air temperature, then plan the trip on 80% of what is left.

Each table computes one steady ride at a time from Freesky's specifications, Bafang's published figures for a comparable 48 V geared hub motor, drum readings for ten fat tires and a cycling-power model checked on a real road. The last subsection gives the formula and walks one ride through it.

Does riding faster cut range? Miles at each speed

Speed settles most of the answer: on the throttle with both motors on, a full charge runs 107 miles at 10 mph and 58 at 20. From 15 mph to 20 the figure falls from 80 miles to 58, because the power the air takes rises with the cube of your speed; 20 mph needs about 2.4 times the air power of 15, which is (20 ÷ 15)³.

Speed, flat Per mile Full charge At an 80% charge
10 mph 13.5 Wh 107 mi 86 mi
12 mph 15.0 Wh 96 mi 77 mi
15 mph 18.0 Wh 80 mi 64 mi
18 mph 21.7 Wh 66 mi 53 mi
20 mph (the default limit) 24.6 Wh 58 mi 47 mi
25 mph 33.7 Wh 43 mi 34 mi
28 mph 40.5 Wh 36 mi 28 mi
34 mph 58.7 Wh 25 mi 20 mi

On the throttle alone, on level pavement, with a 180 lb rider in 77 °F air and both motors on. The table stops at 34 mph, where the stand-in motors reach their rated speed. The last column is what an 80% charge gives, the point at which Freesky's summer charging guide suggests stopping a charge that the ride will not use in full.

Pedaling lightly pays off fast on level ground: 75 W from your legs at 15 mph stretches a full charge from 80 miles to 122. In these tables easy pedaling is 75 W and steady pedaling 150 W. With the motors idle, 75 W alone would move this bike at about 8.8 mph on level ground and 150 W at about 13.0, so pick the column you could hold without help.

Speed, flat Throttle only Easy pedaling (75 W) Steady pedaling (150 W)
12 mph 96 mi 100+ mi legs alone
15 mph 80 mi 100+ mi 100+ mi
18 mph 66 mi 88 mi 100+ mi
20 mph 58 mi 73 mi 94 mi
25 mph 43 mi 49 mi 56 mi
28 mph 36 mi 39 mi 44 mi

Full-pack miles on level pavement for a 180 lb rider, both motors on. "100+ mi" marks any cell past a hundred miles, and "legs alone" marks a speed that 150 W from the rider holds with no help from the motors. That same 15 mph costs 11.8 Wh a mile with easy pedaling and 18.0 on the throttle alone. Above 20 mph the throttle column is a speed past Freesky's default limit, which the class section covers.

The manual gives the same advice in plain words on page 31: "Ride at a lower PAS level", "Use lower PAS levels and pedal when climbing hills" and "Pedal when starting from a standstill."

Which gear and which motors save battery? One motor or two

Pick the gear for your knees and pedal for the battery; pick the motors for the road. On the flat, one motor and two draw nearly the same energy, and on a hill two draw less. A hub motor turns with its wheel in every gear, so a shift changes your cadence and leaves the motors' load where it was; speed, grade and your own watts set that load.

Your ride One motor Both motors Both vs one
15 mph, flat, throttle 18.2 Wh 18.0 Wh −1%
20 mph, flat, throttle 25.7 Wh 24.6 Wh −4%
12 mph, flat, easy pedaling 6.3 Wh 7.4 Wh +17%
10 mph, 4% grade, throttle 61.4 Wh 49.6 Wh −19%
10 mph, 8% grade, throttle 139.5 Wh 99.9 Wh −28%
10 mph, 8% grade, easy pedaling 109.5 Wh 81.3 Wh −26%

Pack watt-hours per mile for a 180 lb rider in 77 °F air. In the last column a minus sign means the second motor lowers the draw. The model splits torque evenly between the motors.

The last column says what the second motor does to the energy: −1% at 15 mph on the flat, −4% at 20, +17% at 12 mph with easy pedaling, and −19% and −28% on 4% and 8% grades at 10 mph on the throttle. On the flat the two modes sit within 4% of each other at a steady throttle; the second motor earns its keep when the load is high.

Freesky's own description matches that split: in its post of September 1, 2025, rear motor mode is for "efficiency" and dual motor mode for "maximum traction and climbing power."

Does going uphill drain the battery faster?

Much faster: at 10 mph on the throttle up 4 to 10% grades, every 1,000 feet you climb costs 171 to 224 Wh with both motors on and 228 to 343 on one motor, on top of what the same distance costs on the level. Lifting the rider and the bike accounts for 47 to 61% of that figure, and the motors and the pack lose the rest, a share that grows as the road steepens.

A 180 lb rider on the 97 lb Warrior Pro weighs 277 lb together, and raising 277 lb through 1,000 feet takes 104 Wh at the wheel.

On an 8% grade at 10 mph with both motors on, the pack pays 205 Wh for each 1,000 feet, so the full 1,440 Wh would climb about 7,011 feet with nothing left for the flat. The model gives no credit for descents, so a budget built from these rows keeps a margin.

Freesky's own photograph of the bike parked on a grassy ridge.

Grade Per mile, both motors Full charge, both motors Full charge, one motor
2% 30 Wh 48 mi 42 mi
4% 50 Wh 29 mi 23 mi
6% 73 Wh 20 mi 15 mi
8% 100 Wh 14 mi 10 mi
10% 131 Wh 11 mi 7 mi
12% 168 Wh 9 mi 5 mi
15% 234 Wh 6 mi 4 mi

All at 10 mph with a 180 lb rider on the throttle. The model holds each motor to the stand-in motor's rated 1,000 W, so it prices a climb's energy; how fast the Warrior Pro climbs a grade depends on motors Freesky rates at 2,000 W peak each, so no climbing speed is printed.

For a hilly ride, price the level miles from the speed tables and the climbing from the hills table, then add them. Twenty level miles at 15 mph on the throttle use about 360 Wh, and 1,000 feet of 8% climbing with both motors on adds about 205, near 565 Wh of the 1,440 in all. Wind, stops and starts come on top, because each mile in the model is ridden at an even pace.

Does rider weight affect range?

Load matters little on level ground and a great deal on a grade. More mass loads the tires and the slope and leaves the air untouched, so the gap between rows grows with the grade.

You plus your load 15 mph flat, throttle 20 mph flat, throttle 8% climb, 10 mph
130 lb 87 mi 62 mi 19 mi
180 lb 80 mi 58 mi 14 mi
300 lb 68 mi 51 mi 9 mi

The rider plus whatever they carry; the bike's own 97 lb is added to every row as well, since the motors move it too. Throttle only, both motors on. The 300 lb row is the load capacity Freesky's U.S. page prints, which that page counts as the rider and cargo; Freesky's other stores print 400 lb.

Moving from 180 lb to 300 lb takes 12 miles off the level 15 mph ride, from 80 to 68, and cuts the 8% climb from 14 miles to 9, because on a grade most of the wheel's power goes into lifting the load.

Does cold weather drain the battery?

Yes: each colder row below costs more range than the last. Easy pedaling at 15 mph takes 122 miles at 77 °F, about 93 at 32 °F and 83 at 14 °F.

Air Pack energy vs 77 °F 15 mph, easy pedaling 20 mph, throttle
95 °F 99% 131 mi 61 mi
77 °F 100% 122 mi 58 mi
68 °F 98% 115 mi 56 mi
50 °F 93% 101 mi 50 mi
41 °F 91% 96 mi 48 mi
32 °F 89% (80–93) 93 mi (83–97) 47 mi (42–49)
14 °F · below Freesky's floor 82% (40–83) 83 mi (40–83) 42 mi (20–42)

Level ground, 180 lb aboard, both motors on. The middle figure in each row comes from McMaster University's LG HG2 cell data, recomputed at a 0.5C discharge; the lab measured 77, 50, 32 and 14 °F, the rows between are interpolated, and the cells are assumed to sit at air temperature. Freesky prints Samsung cells on some pages and LG on others, so the LG data stand in for whichever make the pack carries.

The figures in brackets show how far published cell data disagree. Each low end is the smallest capacity Samsung's data sheets give at that temperature for a cell discharged at one to four times its capacity per hour (the 25R and 30Q at 32 °F, the 35E at 14 °F); each high end is the most energy Casado and colleagues measured at a slower rate.

Three losses add up at freezing. The cells deliver about 89% of their 77 °F energy at freezing (80 to 93%, depending on the source), and the gas law in the U.S. Standard Atmosphere makes the air about 9% denser.

Cold rubber is the third: the model raises rolling resistance 0.5% for each °F below 77 °F and lowers it at the same rate above, between Rothhämel's fit for a 42 mm tire and Bicycle Rolling Resistance's road-tire average.

At 95 °F the model lands slightly ahead of 77 °F: warm tires and thin air save more than the cells give up. Whatever the air on the ride, the manual allows the pack to be charged only between 0 °C and 40 °C, so a winter rider brings it indoors to warm before plugging in.

Do fat tires cut range? Tires and riding position

Tire choice moves range more than posture does on level ground. Bicycle Rolling Resistance's drum measured ten 26 × 4.00 fat tires at 23.2 to 42.1 W at 12 psi, 18 mph and a 94 lb load. Freesky does not name the Warrior Pro's tread on the pages we read, so the model takes the middle of the ten, a coefficient of 0.0105, as the stand-in.

Rolling resistance 15 mph, throttle 15 mph, easy pedaling 20 mph, throttle
0.0070 · lowest of ten 93 mi 153 mi 65 mi
0.0105 · median of ten (used here) 80 mi 122 mi 58 mi
0.0126 · highest of ten 74 mi 109 mi 55 mi

Miles from a full pack for a 180 lb rider on level ground, both motors on. The Schwalbe Jumbo Jim LiteSkin rolled easiest of the ten and Kenda's Juggernaut Pro hardest, which the site lists at 0.01262.

The manual says on page 27: "Freesky recommends 16-20 PSI for the stock tires." That is firmer than the drum's 12 psi. Sand, dirt and grass have no drum reading at all; send us a route and we will run it through the model.

Posture starts to count as speed rises. The model's drag area is 0.603 m², the value Tengattini and Bigazzi measured for 90 everyday riders on mountain bicycles, chosen because the Warrior Pro's flat bars and big knobby tires match that group.

Their 0.640 m² for 37 upright cruiser riders would take the 20 mph throttle ride from 58 miles to 56, and the 0.357 m² of seated mountain-bike cyclists in a field coast-down study would take it to 80.

Freesky's 60 to 95 miles and 60 to 120 miles, matched to real rides

Freesky has printed more than one range for the Warrior Pro, and each one maps onto a steady ride. Its U.S. page of October 10, 2025 gives 60 to 95 miles on one motor and 40 to 60 on two; its post of September 1, 2025 and its Canada and UK pages of October 14, 2026 give 60 to 120 miles on one motor and 40 to 60 on two.

The manual says what any such figure is: "The listed range and top speed of the bike are estimates, not guarantees of performance" (page 31).

  • 120 miles allows 12.0 Wh per mile: about 8.0 mph on the throttle, or 15.6 mph with easy pedaling.
  • 95 miles allows 15.2 Wh per mile: about 12.3 mph on the throttle, 17.4 with easy pedaling or 20.2 with steady pedaling.
  • 60 miles allows 24.0 Wh per mile: about 19.1 mph on one motor's throttle (19.6 on two), or 22.3 with easy pedaling on two.
  • 40 miles allows 36.0 Wh per mile: about 26.1 mph on the throttle with both motors on, or 27.8 with easy pedaling.

So the top of Freesky's one-motor band fits easy pedaling in the mid-teens, its 60-mile figure fits riding near the 20 mph default, and its 40-mile floor fits riding near 26 mph, past that default.

The model's 15 mph throttle ride, 80 miles, falls inside the one-motor band; its 20 mph throttle ride, 58 miles, falls inside the two-motor band; and easy pedaling at 15 mph, 122 miles, runs a little past the 2026 band's top of 120. Read this way, Freesky's two bands describe how fast a rider goes more than the cost of a second motor, which the model prices within 4% of one on the flat.

Base your plans on 80% of whichever figure fits your ride. Freesky's charging guide suggests stopping at that level when the ride will not use the whole pack, which leaves 20% in the pack as a reserve. On the throttle at 15 mph with both motors on, that is 64 miles of the full 80.

Read your row, then plan on 80% of it. Every 1,000 feet of climbing at 10 mph costs 171 to 224 Wh with both motors on, less when you pedal. Planned on 80%, a 180 lb rider on level pavement has 64 miles at 15 mph on the throttle or 47 at 20.

Twenty level miles at 15 mph and 1,000 feet of 8% climbing use about 565 of the 1,440 Wh with both motors on, well inside the 1,152 Wh an 80% charge holds. If your rides are longer than that, our guide to long-range e-bikes compares what each maker publishes, and sending us your distance, climbing and weight gets you our computed answer for any Freesky we carry.

How every figure here is worked out

Holding a steady speed takes a steady flow of power at the wheel. Martin and colleagues' 1998 model, validated on an open road, gives that power in one line for a constant speed in still air:

Power at the wheel = v × [ m × g × (Crr × cos θ + sin θ) + ½ × ρ × CdA × v² ]

Here v is speed, m the combined mass of rider, cargo and bike, g gravity, θ the angle of the slope, Crr the tires' rolling resistance (0.0105 is a drag of 1.05% of the weight on the tires), ρ the density of the air and CdA the drag area, a measure of how much air the rider pushes aside.

The first bracketed term covers the tires and the grade and the second the air; multiplied by v, the air term grows with the cube of the speed.

Four steps lie between the wheel and the battery:

  1. Your legs drive the rear wheel through the chain at 97.7% efficiency, Martin and colleagues' figure, and the motors make up the difference.
  2. The two hub motors do all of the motors' pushing, each turning with its own wheel and sharing the load evenly in the model.
  3. Each motor is modeled on a comparable motor's published figures. In Bafang's 2021 OEM workbook, the RM G0H0, a 48 V geared hub, has an n0 of 510 rpm, an nT of 426 rpm, a rating of 1,000 W and an efficiency of "≥ 80" percent. On Freesky's 29.3-inch wheel those speeds come to 44.5 and 37.1 mph, which is why no row here goes past 34 mph. The model uses 80% at the rated point and lets efficiency fall at lighter loads.
  4. The pack loses some energy inside itself, at the battery efficiency Arango, Lopez and Ceren measured on a 48 V pack.

Then watt-hours per mile = battery watts ÷ mph, and miles = 1,440 Wh × the share of the pack's energy left at that temperature ÷ watt-hours per mile.

One ride, worked through: 180 lb aboard, 15 mph, level pavement, throttle only, both motors on. Rolling takes 87.1 W and the air 107.6 W, which adds up to 194.7 W at the wheels. At that speed the 29.3-inch wheels spin at 172 rpm.

In the motor model (0.899 N·m of torque per amp, a 0.304 Ω winding and a 1.10 A no-load current, each worked out from Bafang's published figures), each motor makes 5.4 N·m on 7.1 A at 75% efficiency, under its 80% because the load is light, and the pair draws 261.1 W.

With the pack's own losses added the battery supplies 269.2 W: 17.95 Wh a mile at 15 mph, and 1,440 ÷ 17.95 comes to about 80.2 miles, or 64.2 from an 80% charge.

Two published benchmarks, recomputed. Each half of the model reproduces the figure its source prints:

Check Published figure This model
Road physics, Martin and colleagues' worked example 45.7 W for tires and grade, 158.8 W for the air 45.8 W and 158.8 W
The comparable motor at Bafang's rated point at least 80% efficient 80%

Recomputed by the model's self-test: the worked example in Appendix I of Martin and colleagues (8.36 m/s ground speed, a 90 kg system, a 0.3% grade) and the RM G0H0's rated point in Bafang's workbook.

Brakes and lights

Freesky specifies "180MM Hydraulic" brakes on a four-piston caliper, front and rear, to stop a 97 lb bike. Its U.S. page lists "4-piston Hydraulic Brakes" and its Canada page "Dual 4-Piston Hydraulic Disc Brakes", while its post of September 1, 2025 says "large 203mm rotors". Measure the rotor on your bike before you order one.

The manual puts the riding rule plainly under "Use Both Brakes" on page 6: "Relying only on the rear brake will significantly increase your stopping distance."

The Freesky Warrior Pro in Blue from the side, showing the front and rear disc brakes, the rotors and the rear shock

Freesky's own side view in Blue: a disc and caliper at each wheel, and the shock above the chainstay.

The headlight is "800 lumen" in Freesky's September 2025 post and an "800 Lumen LED Headlight" in the feature list of its March 5, 2026 product record. The Canada page's "Steering Light" is a turn-signal system "Integrated into the handlebars" that works "with a simple press of a button", and the post of September 1, 2025 adds "Integrated turn & brake lights".

The manual's night-riding advice on page 23 is to ride with "lights on both the front and rear of your bike."

Full suspension on 26 × 4 tires

The fork is a lockable, adjustable hydraulic unit, and Freesky prints its travel two ways. The U.S. page says "Downhill Full Suspension" and describes a "lockable and adjustable front hydraulic downhill fork and rear suspension"; its Canada and UK pages give a "120 mm Oil-Sprung Front Fork" and a "180 mm Rear Shock"; and the manual's fork chapter says on page 20 that the fork "can move up and down up to 80mm to cushion bumps in the riding surface."

The older manual Freesky's U.S. page linked in October 2025 does not carry that sentence. For your own bike, the two numbers to trust are the ones you can measure on it.

The Freesky Warrior Pro in Blue from the front three-quarter view, showing the suspension fork, the headlight, the front mudguard and the front hub motor

The fork under the headlight, with the front mudguard over a 26 × 4 tire.

The manual describes two controls on the fork: a preload knob on the left leg that stiffens the ride clockwise and softens it counterclockwise, and a lockout lever on the right leg that "can be turned counterclockwise until it stops to completely lock out the suspension fork's travel" (page 20). Locking it out "will typically yield higher efficiency while pedaling", and the manual says so in the same chapter.

The tires are 26 × 4-inch fat tires with inner tubes, run at 16 to 20 psi under the manual on page 27, firmer than the 12 psi in the tire table. Around them sit a Shimano 7-speed rear derailleur, a KMC chain, an "Upgraded 6061 Aluminum" frame and an adjustable heavy-duty aluminum kickstand, in the words of Freesky's page.

97 pounds, and a 300-pound or 400-pound load

Freesky lists 97 lb for the Warrior Pro on its U.S. and Canada pages, and its UK page gives "44 KG (97 lbs)". Load capacity is the figure that moved: 300 lb on the U.S. page archived October 10, 2025 and 400 lb on the Canada and UK pages read October 14, 2026.

Either capacity covers the rider and everything the bike carries; the 97 lb bike is outside it. Freesky's hunting-bike guide of September 8, 2026 says so directly: "Remember that total payload includes the rider and cargo, so always check the specifications for your specific FREESKY model before loading the bike." A 300 lb rider with gear on a 97 lb bike puts 397 lb on the wheels, which sits at the 300 lb figure and well inside the 400.

Size a hitch rack, a lift or a stair plan for the 97 lb plus whatever rides on the bike, and for the 75 inches of length and 43.3 of height in Freesky's Geometry table. The manual's note on moving the bike (page 36) is brief: "Electric vehicles are relatively heavy and need to be careful when moving to avoid causing electric vehicles to flip over."

Settle where the Warrior Pro will live and how it will travel before it arrives. A garage, a ground-floor room or a hitch rack rated for its 97 lb with a margin suits it better than a daily carry up stairs, and the pack comes out when you need to lift less.

The Mercer fit test

Each review we publish puts the bike in front of the same seven people, the Mercers, so every machine answers the same fit questions (meet the Mercers). Each verdict below rests on a figure Freesky publishes (its rider windows, the seat range, the standover figure) or on the age line in the manual, or on the fit tables computed from them. The two share counts in each row are the labeled seat range first and Freesky's drawn lines second.

Member Age · Height Verdict The number behind it
Frank Kowalski 63 · 5'10" Inside both windows; the saddle is his check At 5'10" the post reaches the formula height for 21 of 100 riders on the labeled range and 95 of 100 on the drawn lines
Ruth Kowalski 61 · 5'5" Inside both windows, at the bottom edge At 5'5" the post reaches it for 97 of 100 on the label and 15 on the drawing, and 95 of 100 riders her height clear the standover by 2.6 inches or more
Jack Mercer 48 · 6'1" Inside both windows; the saddle is his check At 6'1" the post reaches it for 1 of 100 on the label and 82 on the drawing
Dana Mercer 45 · 5'7" Inside both windows At 5'7" the count is 81 of 100 on the label and 52 on the drawing
Maya Torres 32 · 5'6" Inside both windows At 5'6" the count is 89 of 100 on the label and 32 on the drawing
Cole Mercer 16 · 5'11" Not until 18 He is inside both windows, and the manual says: "Riders must be at least 18 years old."
Ivy Mercer 12 · — No The manual's 18-year minimum; she is on the table so the answer is here

For this family the question is the top of the post. The standover table clears Freesky's 27.1 inches for 95 of 100 riders at every height from 5'4" up, and the saddle's reach is what separates Frank and Jack from Ruth and Maya.

Is it UL certified?

Yes: Freesky publishes a UL 2849 certificate for the M-530's electrical system and a UL 2271 certificate for its 30 Ah pack, and TÜV SÜD America issued both in 2025. The badges on Freesky's Canada page read "UL2849 Certified by TÜV" and "UL2271 Certified by TÜV"; its U.S. page archived October 10, 2025 carried a "UL2849 Certified" badge and a feature headed "UL2271 Certified Battery".

Certificate What it names Dated
UL 2849 certificate, No. U14 128702 0008 Rev. 00 "Electrical Systems for E-Bikes", brand FREESKY, models M-530, M-540, M-410 and A-340, rated voltage 47.19 V DC, charger 54.6 V DC at 3.0 A, degree of protection IP34 July 31, 2025
UL 2271 certificate, No. U10 128702 0001 Rev. 00 "Batteries (Rechargeable Li-ion Battery)", model FP4830R0, nominal voltage 47.19 V, rated capacity 29.4 Ah, IP code rating IP33 March 17, 2025

Both read October 14, 2026 from the PDFs Freesky's Canada page links; each names GuangZhou Yansan Science & Technology Co., Ltd. as the holder. Check the model number on your pack's label against the second certificate's.

Freesky's own description of the two standards, in its post of May 19, 2026: "UL 2271 focuses specifically on the battery pack itself", while UL 2849 "evaluates the entire electrical system as a complete unit, including: Motor, Controller, Charger, Wiring, Battery integration."

The UL 2849 certificate also rates a charger at 54.6 V DC, 3.0 A, the rating of the 3 A charger Freesky specifies. Should a landlord, a building manager or an insurer want the documents, email us and we will request them from Freesky in writing.

Has it been recalled?

No. Our October 14, 2026 search of the Consumer Product Safety Commission's recall database looked in the recall title, description and product-name fields for Freesky, Warrior Pro, M-530 and Yansan, and no record matched any of them. A fourth field, manufacturer, was queried as well, but its control returned no row, so it does not count toward the answer.

The one stray hit, for "M530" in a description, was a May 26, 1999 recall of stereo speakers by Polk Audio, whose model number RM5300 contains those characters.

Before its empty answer counted, the search of the CPSC database had to find a recall known to exist, and it did: the October 13, 2022 recall of Ancheer e-bikes came back in the title, description and product-name fields, and the two-word phrase "Rocky Mountain" matched 13 times in recall descriptions.

The class question: 20 mph by default, 40 mph published

Settle this before you ride it, because Freesky gives the Warrior Pro more than one top speed. Its U.S. page prints "Top Speed 40 MPH" and "speeds of up to 40 MPH with pedal assist or throttle", while its FAQ says:

All Freesky eBikes are limited to a maximum speed of 32 km/h (20 mph) by default, which complies with local e-bike regulations. If you wish to exceed this speed, you will need to obtain a license, license plates, and insurance for your eBike.

That is two settings in one bike: the Warrior Pro as delivered, whose help ends at 20 mph, and the 40 mph machine on the spec sheet, which Freesky's FAQ ties to a license, plates and insurance. Freesky's post of September 1, 2025 adds: "US: varies by state, with class 1–3 e-bike regulations", and "high-speed modes are best used on private or off-road terrain."

California's definition, in Vehicle Code § 312.5(a) as read on October 14, 2026, requires a bicycle "equipped with fully operable pedals and an electric motor that does not exceed 750 watts of power".

Its class lines follow in the same section: a class 2 bicycle's motor "is not capable of providing assistance when the bicycle reaches the speed of 20 miles per hour", and a class 3 bicycle helps "only when the rider is pedaling" and "ceases to provide assistance when the bicycle reaches the speed of 28 miles per hour".

The federal definition of a low-speed electric bicycle, 15 U.S.C. § 2085(b), covers "a two- or three-wheeled vehicle with fully operable pedals and an electric motor of less than 750 watts (1 h.p.), whose maximum speed on a paved level surface, when powered solely by such a motor while ridden by an operator who weighs 170 pounds, is less than 20 mph."

Setting The speed line Where the Warrior Pro sits
As delivered, help ending at 20 mph by default A class 2 throttle stops at 20 mph in California On the class 2 speed line; the watt line is the open question below
At the 40 mph Freesky publishes Class 3 assist stops at 28 mph, a class 2 throttle at 20 Past both speed lines, where Freesky's FAQ asks for a license, plates and insurance

From § 312.5(a)(2) and (a)(3), Freesky's U.S. page and its FAQ, each read October 14, 2026.

Ask for each motor's continuous rating, in writing. Freesky's figure, "2000W + 2000W Brushless Peak Motors", is a peak and names two motors. California's wording is "an electric motor that does not exceed 750 watts of power" and the federal wording "an electric motor of less than 750 watts"; both are written in the singular, and neither says whether a peak or a continuous figure counts or how two motors are counted.

Where a watt line applies to you, email us and we will get the continuous rating of each motor from Freesky in writing before you decide. Our 50-state e-bike law atlas prints each state's definition, and the manual leaves the checking to you: "Riders are responsible for adhering to all local, state, and federal laws and regulations regarding the operation of electric bicycles" (page 33).

Look at your insurance as well. The manual says on page 30: "Note that your insurance policies may not provide coverage for accidents involving Freeksy eBikes. To determine if coverage is provided, you should contact your insurance company or agent."

As delivered, the Warrior Pro's help stops at 20 mph by default, and Freesky's FAQ ties anything faster to a license, plates and insurance. Before the first ride, read your state's definition and your trail manager's rule, and where a 750 W line applies, have us get each motor's continuous rating in writing.

Where you can ride it

Once you leave the pavement, whoever manages the land decides whether the Warrior Pro may go there, and federal managers start from the e-bike classes, so the 20 mph default and the watt line both count.

The Forest Service's final e-bike directives, issued March 31, 2022, "provide for managing all classes of e-bikes as motor vehicles and require local-level decision-making and environmental analysis to allow use of e-bikes on non-motorized trails", as its notice at 87 FR 41278 puts it.

Where a Ranger District has published a motor vehicle use map, 36 CFR 261.13 bars operating a motor vehicle "other than in accordance with those designations".

On Bureau of Land Management land, 43 CFR 8340.0-5 builds the three classes around "an electric motor of not more than 750 watts (1 h.p.)" and treats an e-bike as a non-motorized bicycle only where "the authorized officer has expressly determined" so.

Where you plan to ride Who decides What to read
A National Forest road or trail the Ranger District its motor vehicle use map (36 CFR 261.13)
BLM land the field office its e-bike decision; 43 CFR 8340.0-5 holds the definitions
A state park, county open space or city path that agency the class wording posted at the trailhead
Private land, your own or with permission the owner the owner's say-so

Each landowner writes its own rule, and a spec sheet answers to none of them.

On a National Forest, 36 CFR 261.1b puts the price of breaking the part's prohibitions at "imprisonment of not more than six months or a fine in accordance with the applicable provisions of 18 U.S.C. 3571 or both". Agency by agency, our public-land e-bike guide sets out who decides what.

Tell us the trails or land you plan to ride before you choose a bike. We will give you a plain answer on whether the Warrior Pro's settings fit the rule there, plus the continuous motor rating in writing if a watt line applies, and see our guide to electric mountain bikes for what we carry in the same class.

What owners say

Owners rate the Warrior Pro 4.92 out of 5 across 166 reviews on Freesky's review widget, 152 of them five stars and 14 four stars, written between February 24, 2024 and September 22, 2026. The widget marks 125 of the 166 as verified buyers. Sixty are dated before November 20, 2024, the day the record the widget belongs to was created, so they may describe an earlier build.

That record carried the name Warrior Pro M-530 in Freesky's capture of March 5, 2026 and in its feed on October 13, 2026; the newest review, from September 22, 2026, comes before Freesky's feed gave it another model's name on October 14. Everything quoted below is owners' own words, dated, and none of it is our measurement.

On power and hills, an owner who bought one in February 2025 wrote: "I am a stocky fellow, 5ft 10in 240lbs and it has no problem pulling me up a hill." The same owner added: "Using one motor, I can ride all day long in the hills of Alabama and still leave with 40% battery."

In February 2026 another owner wrote: "Although quite powerful running rear motor only having the dual motors takes it to another level especially on hilly trails loaded with gear."

On fit and size, an owner wrote in March 2025: "Im 6ft4 and 215 lbs and this bike fits well." In February 2026 one wrote: "6'3" 275lbs and doesn't even phase this beast."

On weight, a verified owner wrote in July 2026: "It is a little heavy, but for what bought it for it is great." The same review says: "With the front motor engaged it is great for going through longer or wet grass."

Freesky's own blog carries a UK owner's account from April 24, 2026, who wrote that building the bike "took just over an hour to assemble". Treat every line here as a lead about one rider's bike, and weigh the 166 as a whole: they average 4.92 and they cover more than one build.

Settings, passwords and the manual

Freesky's U.S. page linked one manual in October 2025 and its Canada page links another now; this page quotes the newer one and says where the older one differs. The file Freesky's U.S. page archived October 10, 2025 linked is Warrior_Pro_M-530_user_manual.pdf, and the Canada page links M-530_Instruction_English.pdf. Both carry the first-ride, saddle, tire-pressure and age text quoted here; only the newer one has the fork's 80 mm sentence and the "recommended charger" sentence.

Turning it on. The manual says on page 22: "Then, use NFC to swipe the screen, or hold the power button and then enter the password: 1212 to turn on the bike." Freesky's post of September 1, 2025 calls it "NFC card or password unlock (default: 1212)". The battery comes first: take it out, press its switch, and put it back, because it ships off (the battery section).

Choosing an assist level. The manual, page 22: "Level 1 corresponds to the lowest level of pedal assistance, and level 5 corresponds to the highest level of pedal assistance. Level 0 indicates pedal assistance is inactive. Start in PAS level 0 or 1 and adjust from there."

The settings menu, in Freesky's own words. The FAQ on its U.S. page gives two procedures and nothing more:

What you want The steps the FAQ gives, and its warning
Miles or kilometers Hold "+" and "-" for 3 seconds; "If prompted, enter code 1313"; press POWER until P02 appears and set it to 00 for kilometers or 01 for miles; long-press POWER to save. The warning beside it: "DO NOT modify other parameters!"
A softer start Set P11 to 24 ("Higher value ↑ = Slower response") and P12 to 01 ("Lower value ↓ = Weaker startup acceleration"). The FAQ adds "Changes are subtle, not drastic" and "AVOID adjusting other settings!"

We print no other parameter, because Freesky prints none.

What the documents leave out. Neither the manual nor the U.S. page of October 10, 2025 describes a step for raising the 20 mph default; the page's FAQ describes the license, plates and insurance Freesky asks for beyond it, and the class section sets that beside the statutes.

Freesky's post of March 20, 2025 lists "Bluetooth Connectivity: Sync with the mobile app to access advanced settings", while the manual and the October 2025 page describe no app; if yours came with one, email us the serial number and we will ask Freesky what it covers.

Serial numbers matter. The manual (pages 2 to 4) asks you to note three: the frame's, "engraved on the head tube"; the motor's, found "on the motor, starting from the left side (brake disc side)"; and the display's, "on the back of the display". It also says: "Please register your Freesky Ebike warranty upon receiving the bike", at Freesky's registration page.

Freesky's own instruction for a replacement battery, motor or fork is the same serial number, in its words, on its front-fork listing: "To ensure compatibility, the front fork must be purchased based on the specific model and serial number of your vehicle."

Parts we sell for the Warrior Pro

Freesky's own listings name the Warrior Pro for every part below, and each was orderable on our store on October 14, 2026 except the one marked sold out. Prices are ours, read from our listings that day; the fitment column carries Freesky's own wording, read from its product record on October 13, 2026. Our Freesky parts collection lists every one.

Phone mount ($22.80), helmet ($70.80), air pump ($58.80), lock ($22.80) and bottle holder ($34.80) are on our shelf too, and Freesky's listings name the Warrior Pro for each. Our prices come from our listings on October 14, 2026.

Which pack is yours depends on the label. Freesky's page of September 18, 2024 described a 48V 25Ah pack and its page of December 11, 2024 a 48V 30Ah one, so a bike bought in 2024 may carry either, and Freesky sells both variants.

Freesky's listings for the pack, the motor and the fork say "shipping will take approximately 30-45 days"; our parts pages ask for your bike's model and serial number after you order. Email us the serial number first and we will confirm the fit with Freesky in writing and give you our delivery estimate before you pay.

Freesky lists a brake rotor and brake pads without naming a model. On our shelf its 180MM disc is $42 and its brake pad is $30, and neither listing names the Warrior Pro, so send us your serial number and we will confirm both with Freesky in writing before you order.

A spare pack is the part owners ask about first. The 48V 30Ah pack was orderable at $720 and the 25 Ah pack at $660 on October 14, 2026; check your pack's label against them before you buy, and send us your serial number first if you want the fit confirmed. Our parts collection lists the pack, brakes, fork, motors and the rest.

Green flags / Red flags

Green flags

Red flags

These are about fit: who the Warrior Pro is wrong for, and where to look instead.

  • Wrong if you want the formula's saddle height and you are 5'9" or taller. On the labeled 35 to 40 inches the post reaches it for fewer than half of riders from 5'9" up; our guide to e-bikes for tall riders is the next read, and we will put your height and inseam through the model.
  • Wrong if you need to ride it today. Our listing is sold out; our Freesky brand page lists the Freesky models we can ship.
  • Wrong if a 750 W line applies where you ride. Freesky prints a peak per motor; our 50-state law atlas lists each state's definition, and we will get each motor's continuous rating from Freesky in writing.
  • Wrong if rider and cargo together run near 300 lb and you need Freesky's 400 lb rating in writing. Email us and we will ask Freesky for the rating that applies to your build.
  • Wrong for a daily carry up stairs. At 97 lb, stairs and hitch racks may need a second person; tell us about the stairs and we will suggest a lighter bike from our range.
  • Wrong if you need the longest range a battery can buy. A 1,440 Wh pack computes to 80 miles at 15 mph on the throttle; our long-range guide collects bikes built around bigger packs.
  • Not for riders younger than 18. The manual sets 18 as the minimum age to ride, and our 50-state law atlas lists what each state adds.
  • Wrong for Class 1-only trails. The throttle keeps it off them; our public-land guide quotes each agency's rule, and we will check a specific trail with you.

Buy it if / Buy something else if

Buy it if you own one, or you find one whose label matches the specification you want, and you want a full-suspension fat-tire bike with a motor in each wheel that computes to 80 miles at 15 mph on the throttle and 58 at 20, with a one-motor mode for range and a two-motor mode for hills.

It asks that you be 18 or older, as the manual requires, and inside Freesky's rider window, with the saddle at the top of its post if your inseam runs past 33.0 inches.

The running cost is small: at 18.31 cents per kWh, the U.S. residential average for July 2026 in the Energy Information Administration's Table 5.6.A, a full 1,440 Wh charge costs about 26 cents before the charger's losses, and charging for 1,000 miles a year at 15 mph on the throttle costs about $3.29 a year.

Owners rated the bike 4.92 out of 5 across 166 reviews on Freesky's widget, across more than one build.

Buy something else if you need the longest range a battery can give, which our long-range guide covers; if you want a different dual-motor setup, which our dual-motor guide covers; if your trails allow Class 1 bikes only, in which case email us the trail system and we will match a bike to its rule; or if you want a bike you can order today, which our Freesky brand page shows.

How we verify our reviews, and how the bikes we have reviewed compare side by side, is set out on our e-bike reviews hub.

Before you buy: the checklist

Ten checks before you pay for a Warrior Pro from anyone, new or used; the first three settle which machine you would be buying.

  1. Read the motor label and the pack label. Freesky's pages have printed 1,000 W and 2,000 W peak per motor, and a 25 Ah and a 30 Ah pack; match both to the specification table.
  2. Ask for the serial number. Freesky's U.S. page says its warranty "applies only to original owners and is not transferable", and parts are ordered by serial number.
  3. Ask which manual came with it, and which equipment set: with or without the rack and mudguards.
  4. Find the rule where you will ride: your state's e-bike definition governs roads and paths, and the land manager's rule governs trails.
  5. Check the rider's age: the manual sets a minimum of 18.
  6. Ask us for each motor's continuous rating in writing wherever a watt line applies.
  7. Measure your inseam and find your row in the fit tables; above 33.0 inches the saddle runs at its highest setting on the labeled post.
  8. Add up the rider and all the cargo and stay inside whichever capacity Freesky gives your bike, 300 or 400 lb; the bike's 97 lb is separate.
  9. Decide where it lives and how you lift it: 97 lb and 75 inches before any cargo.
  10. Price your own ride in the range tables, keep 20% back and add the climbing.

Frequently asked questions

How fast is the Freesky Warrior Pro?

As delivered, its help ends at 20 mph; Freesky publishes 40 mph. Freesky's U.S. page prints "Top Speed 40 MPH" and its FAQ ties anything past 20 mph to "a license, license plates, and insurance"; its captures from September 2024 to August 2025 printed 38 mph. The class section sets both beside the statutes.

How far can the Freesky Warrior Pro go on one charge?

About 80 miles at 15 mph on the throttle for a 180 lb rider on flat pavement, 58 at 20 mph and 122 at 15 mph with easy pedaling, computed from Freesky's figures. Freesky prints 60 to 95 miles on one motor and 40 to 60 on two, and 60 to 120 on one motor on its other stores. The range section prices your own ride.

How much does the Freesky Warrior Pro weigh?

97 lb, on Freesky's U.S., Canada and UK pages. Its load figure is 300 lb on the archived U.S. page and 400 lb on its other stores, and either covers the rider and cargo with the bike's own 97 lb on top. The weight section works through racks and lifting.

How many watts is the Freesky Warrior Pro?

Freesky prints 2,000 W peak for each of two motors, 4,000 W combined, and its page printed 1,000 W for each through August 3, 2025. No capture we read prints 2,800 W. A peak is a ceiling, so the motor section explains the rated figure the range model uses.

Partly: as delivered its help ends at 20 mph, which sits on the class 2 speed line, and at the 40 mph Freesky publishes it is past every class line. Whether a 750 W limit applies depends on a continuous rating Freesky does not print for each motor. The class section quotes the statutes, and we will get the rating in writing.

How do I turn on or unlock the Freesky Warrior Pro?

Switch the pack on, then swipe NFC or hold the power button and enter the password 1212 (manual page 22); the settings menu opens by holding "+" and "-" for 3 seconds, with code 1313 if asked. Those are Freesky's own words. The settings section quotes the rest and says where the two manuals differ.

Will the Freesky Warrior Pro fit me, and is it good for tall riders?

Yes inside Freesky's window, with the saddle's reach as the check. The U.S. page gives 5'5" to 6'3" and its other stores 5'5" to 6'8"; at 5'10" the post reaches the fit formula's height for 21 of 100 riders on the labeled 35 to 40 inches and 95 on Freesky's drawn lines, and from an inseam of 33.0 inches up the formula asks for more saddle height than the labeled post gives. The fit section prints both.

Can you replace or upgrade the Warrior Pro's battery?

Yes: the pack comes out with its key, and Freesky sells replacements named for the Warrior Pro. We list "Warrior Pro 30AH" at $720 and "Warrior 25AH" at $660; match the label on your pack and order by serial number, since Freesky's own listing says shipping "will take approximately 30-45 days". The parts section has the details.

Which brakes and brake pads fit the Warrior Pro?

Freesky's Warrior brake sets, named for this bike: front or rear at $96 each, both at $168 on our store. The specification is "180MM Hydraulic" with four-piston calipers. Freesky's pad ($30) and rotor ($42) listings name no model, so send us your serial number and we confirm in writing first. The brakes section has the manual's braking rule.

Does the Freesky Warrior Pro come with a rear rack and fenders?

The 2026 equipment set does, and the 2025 set did not. Freesky's Canada page lists "Rear Rack" and "Front & Rear Mudguards" under "What You'll Receive", while the manual's box list names neither and the 2025 photographs show neither. A rear rack package for the Warrior is $144 on our shelf and sold out. The specification section shows both photo sets.

Is the Freesky Warrior Pro waterproof?

Splash-resistant, not submersible: Freesky's FAQ says "IPX4 splash-resistant (withstands light rain/wet roads)". It lists what to avoid, "Riding in heavy rain/storms", "Submerging in water (depth above pedals)" and "Pressure washing", and says to dry the chain after rain, apply lubricant, and wipe moisture near the controller and the battery compartment.

How long does the Warrior Pro battery take to charge?

About 10 hours, by Freesky's U.S. page; its September 2025 post says 8 to 10. The UL 2849 certificate rates the 3 A charger at 54.6 V DC and 3.0 A, which is up to 163.8 W, so 1,440 Wh takes at least 8.8 hours before losses. Charge only between 0 °C and 40 °C (manual page 12).

Does the Warrior Pro arrive assembled?

Partly: the manual's box list holds the bike with its front wheel, two pedals, a saddle, a headlight and tools to attach. Its assembly chapter covers the headstock, front wheel, headlight, saddle and pedals, and it asks for a mechanic's inspection before the first ride; a UK owner wrote that the bike "took just over an hour to assemble".

Can you ride the Warrior Pro on one motor?

Yes: Freesky's pages describe "switchable rear-wheel drive and dual-motor drive modes", and the manual starts a first ride on "rear-wheel drive only". On the flat, the model prices one motor and two within 4% of each other; on an 8% grade at 10 mph two draw −28% against one. The range section has the table.

Is a dual-motor e-bike better than a single-motor one?

Better on hills and loose ground, no better on the flat. The model's second motor changes energy per mile by −1% at 15 mph on the flat and −28% on an 8% grade at 10 mph, and it adds a second motor to maintain; Freesky sells the front and rear motors as separate parts, $540 and $576 on our shelf. The range section has the numbers.

Can the Warrior Pro climb steep hills?

Yes, on the energy side: an 8% grade at 10 mph costs 205 Wh per 1,000 feet with both motors on, so a full charge climbs about 7,011 feet. Freesky rates the pair at 240 N·m, and an owner at 240 lb wrote that it "has no problem pulling me up a hill". How fast it climbs depends on motors rated by peak, so we print no speed. The hills table has the grades.

Is the Freesky Warrior Pro still for sale, and what did it cost?

Not from us: our listing is sold out, and Freesky's U.S. page for it answered "page not found" on October 14, 2026. Freesky's own price was $1,849 in September 2024, $1,949 in March 2025, $1,749 in October 2025, $1,849 in March 2026, $1,749 in its U.S. feed on October 13, 2026 and $1,999 on a newer record in that feed on October 14. The availability section has each date.

How does the Warrior Pro compare with the rest of Freesky's lineup?

Freesky sells more than one dual-motor model, and our brand page lists each current one with what we can ship. This review prices only the Warrior Pro, 1,440 Wh with 2,000 W peak per motor by Freesky's figures. Our Freesky brand page and our dual-motor guide are the places to compare.

What do owners say about the Freesky Warrior Pro?

They rate it 4.92 out of 5 across 166 reviews on Freesky's widget and write about power on hills, size and weight. A 6'3" owner at 275 lb wrote that it "doesn't even phase this beast", and a verified owner called it "a little heavy". The owners section quotes more.

Is the Freesky Warrior Pro UL certified, and has it been recalled?

Yes to the first, no to the second. Freesky publishes UL 2849 for the electrical system (July 31, 2025) and UL 2271 for the 30 Ah pack (March 17, 2025), both issued by TÜV SÜD America, and our October 14, 2026 search of the CPSC's database found no recall naming Freesky, Yansan, the Warrior Pro or the M-530. The UL section and the recall section have the records.

Limitations of this review

Twenty things this review cannot settle, listed so you can weigh them.

  1. We sell Freesky e-bikes and parts. Read the red flags as closely as the green.
  2. This is a specification-verified review. Its figures come from Freesky's published documents, statutes, our own store record, the published research the range and fit sections cite, or arithmetic on this page.
  3. Freesky's U.S. page for the Warrior Pro was not being served on October 14, 2026. Its U.S. figures come from the capture of October 10, 2025, its product record and the documents it published; the Canada and UK pages carry a newer specification, and wherever the two differ this page prints both.
  4. Each range figure is for one steady ride, at one speed on one grade, with no wind and no stops. Wind, stops and starts cost more, and a tailwind less.
  5. Bafang's figures stand in for Freesky's motors. Freesky prints a peak for each motor; the model uses Bafang's published figures for a 1,000 W 48 V geared hub and splits the load evenly, because how Freesky's controller shares torque is not published. At 82% efficiency in place of Bafang's 80% floor the 15 mph throttle figure moves from 80 miles to 89; on Bafang's 750 W version it is 81.
  6. No ride of this model to an empty battery was available to check the model against. Six video reviews read in full carry speeds and impressions, one that logs time and speed gives no measured pack voltage, and a seventh could not be read; the 166 owner reviews describe partial rides. The physics reproduces Martin and colleagues' worked example, and the motor reproduces Bafang's 80% at the rated point.
  7. Every figure assumes Freesky's 1,440 Wh. At the pack certificate's 47.19 V and 29.4 Ah the pack holds 1,387 Wh, 3.7% less, and at 47.19 V and 30 Ah it holds 1,416 Wh; every mile figure scales with that energy. The documents read here do not say how much of the pack the battery management releases.
  8. The tire coefficient is the median of ten 26 × 4.00 fat tires at 12 psi; Freesky does not name the Warrior Pro's tread on the pages we read, and the tire table brackets the choice with the lowest and highest of the ten.
  9. The cold figures rest on one cell's laboratory data. Freesky prints Samsung cells on some pages and LG on others, so the central line uses McMaster University's measured LG HG2 cell, bracketed by other published cell data, with the cells assumed to be at air temperature.
  10. Freesky publishes more than one figure for the same row on the motors (1,000 W or 2,000 W each), the top speed (38 or 40 mph), the range (60 to 95 miles, or 60 to 120), the load (300 lb or 400), the cells, the controller, the rider window and the fork's travel. The specification section prints each with its date and this review follows the archived U.S. page for the model's primary figures.
  11. The manual differs from the page on two rows. The page prints a thumb throttle, while the manual describes "rotating the throttle backward toward the rider" (page 22), and the Canada and UK pages give the fork 120 mm while the manual says "up to 80mm" (page 20).
  12. The fit tables stop at 6'4". The Army survey holds 35 men and women at 6'4", 17 at 6'5", 6 at 6'6" and none above, so Freesky's 6'8" top is beyond what the tables can say.
  13. Freesky's drawing and its labels disagree on the saddle. The model keeps the labeled seat range as its answer and prints the drawn lines beside it; the seat post's angle is measured on the drawing because Freesky publishes none.
  14. The owner reviews span builds. Sixty of the 166 are dated before November 20, 2024, the day the record they sit on was created, and on October 14, 2026 Freesky's feed gave that record another model's name; every review is dated before the change, and none is used for fit.
  15. Trail access is set locally. Your land manager's rule decides, it can change, and neighboring systems differ; this page does not replace it.
  16. The recall search covers the CPSC's US database under the names listed; a recall filed under another company name would need that name searched, and the manufacturer field's control returned no row, so it is not counted.
  17. Freesky's feed moved the Warrior Pro name to another record while we read it. The record it named Warrior Pro M-530 was priced $1,749 on October 13, 2026 and the record carrying that name on October 14 was priced $1,999; our listing is sold out, so no price here is an offer.
  18. The fit figures use the US Army's ANSUR II bodies: 6,068 soldiers aged 17 to 58, measured in 2010 to 2012, who are not the US public, so your own inseam decides your row.
  19. The hand figure is a ceiling with a relaxed back. On a real ride your back and arms carry part of it, and we found no study that measures the hand load on a bike set up like this one.
  20. The 109% formula is a starting point. In 19 trained cyclists it put 55 to 65% inside the 25-to-35-degree knee range and the heel check put 70%, so the knee range and the heel check set the saddle.

The bottom line

The Freesky Warrior Pro is a full-suspension fat-tire e-bike with a motor in each wheel, a one-motor mode for range and a two-motor mode for hills, and on October 14, 2026 it is one we cannot ship.

A 180 lb rider on level pavement can count on about 80 miles at 15 mph on the throttle, or 122 with easy pedaling, and every 1,000 feet of climbing at 10 mph costs 171 to 224 Wh with both motors on. Charging for 1,000 such miles a year costs about $3.29 a year at the Energy Information Administration's July 2026 residential price.

If you own one, the parts we sell for it were orderable on October 14, 2026 and the settings section holds Freesky's own steps.

If you are shopping, read the label on any Warrior Pro for its motors, pack and equipment set against the specification table, check the saddle's reach against the fit tables, and sort out the class before you ride past 20 mph.

If you want a Freesky we can ship, our brand page shows what is orderable; tell us where you ride and we will match one to it, and get a motor's continuous rating in writing where a watt line applies.

The Warrior Pro is sold out here, and the rest of the Freesky line is one page away. Our brand page shows what we carry and can ship; an email to support@redtailebikes.com with your height, inseam, route and weight gets you the same computed answers this review prints, for the Freesky that fits you.
