Freesky Cheetah MT-380 moped-style dual-motor fat-tire electric bike in Red on a studio floor, side profile showing the long two-person seat, the red tank cover, the twin rear coil shocks and both hub motors

Moped-style frame · 2 × 2,000 W peak hub motors · 120 N·m per motor · 48 V 60 Ah, 2,880 Wh · 120–200 miles on pedal assist · 20 mph each time it starts · seat for two · 122 lb · 400 lb capacity · $1,849 · verified September 25, 2026

Quick Answer — The Freesky Cheetah MT-380 is a $1,849 moped-style fat-tire e-bike with two 2,000 W peak hub motors, a 48 V 60 Ah battery and a long seat for two, limited to 20 mph each time it starts. On both motors a 180 lb rider on flat pavement gets a computed 151 miles at 15 mph on the throttle.

At 20 mph the same full charge runs about 112 miles. Freesky's own figure is 120 to 200 miles on pedal assist, and the range section turns it into the ride you have in mind: your speed, your hills, your load with or without a passenger, the weather and the tires, on one motor or both.

The speed rule comes first. Freesky's FAQ says exceeding the 20 mph default needs "a license, license plates, and insurance", and the class section sets that beside the statutes; the passenger section does the same for the second seat.

On September 25, 2026 the Cheetah was orderable on our store at the price Freesky charges on its own: $1,849, with $3,049 shown as the regular price on both stores. It comes in one colorway, Red, and ships free within the contiguous United States.

A 2,880 Wh moped-style bike with a seat for two

The Cheetah looks like a small motorcycle and keeps a bicycle's pedals, chain and gears. A long bench runs from the red tank cover to the tail, a hub motor sits in each 20-inch wheel, and a removable 48 V 60 Ah pack is built into the frame in what Freesky calls an "integrated design".

Freesky's page titles it a "Dual-Motor Electric Motorbike" and describes "a moped-style electric motorcycle"; its comparison chart files it as a "Moped-style eBike".

From the front: the headlight grille, the fork and the front hub motor, with the long seat behind the tank cover.

The seat is what sets it apart. Freesky's page promises "tandem seating" and "an extended, cushioned saddle designed for both rider and passenger", with "Dedicated foldable footrests for rear passengers". The passenger section reads that against the law, because a seat built for two does not settle where two may ride.

Freesky published the Cheetah's product record on September 22, 2025, and on September 25, 2026 its page and ours both sold the Red Cheetah for $1,849, with $3,049 as the price shown crossed out.

Sizing: 5'4" to 6'5" and a seat fixed at 35 inches

Freesky publishes one size of Cheetah, for riders from 5'4" to 6'5" with inseams of 27 to 35 inches.

Geometry Freesky's figure
Rider height 5'4"–6'5"
Inseam 27"–35"
Seat height 35.0" lowest and highest
Standover height 28.7"
Reach 18.5"
Wheelbase 46.9"
Total length 70.1"
Total height 45.7"
Wheel diameter 24"

Freesky's Size & Fit and Geometry tables on the product page, read September 25, 2026; both tables print the same figures.

The seat does not go up or down, so your inseam decides the fit. The geometry table prints 35.0 inches as both the lowest and the highest seat height, and the manual adjusts the saddle only "backward or forward" and in tilt, recommending "A seat position horizontal to flat ground" for most riders.

Measure your inseam in socks against a wall and compare it with 35 inches: the closer you come, the more of your foot reaches the ground at a stop. The other number is Freesky's 28.7-inch standover height, the frame height you straddle when you stand over the bike; there is no step-through, so you mount by swinging a leg over the seat.

At 70.1 inches long and 45.7 inches tall in Freesky's geometry table, the Cheetah needs a garage bay or a ground-floor room more than a hallway, so measure where it will live as well.

One frame fits riders from 5'4" to 6'5", with a seat that stays at 35 inches. Email us your height and inseam and we will hold them against Freesky's seat and standover figures before you pay; the Cheetah is $1,849 in Red, its only colorway.

Two 2,000 W peak motors and 240 N·m

Freesky lists "2000W + 2000W Peak Motor" and "a combined 4000W peak power and 240 N·m torque", and its comparison chart splits the torque as "120 N·M*2". Peak output is the short burst a motor can give; what it can sustain is its continuous rating.

Freesky's torque explainer of August 14, 2026 lists the Cheetah at "120 N·m × 2" and matches it with "Extreme terrain and maximum climbing force".

The rear hub motor of the Freesky Cheetah with its seven-cog freewheel, the chain and the rear brake rotor

The rear motor sits in the hub, with the seven-cog freewheel threaded onto it; Freesky pairs this picture with the motor in its feature list.

Each hub motor spins with its wheel. Shifting gears changes how fast your legs turn and nothing about the motors, so the choice that moves the battery is how many motors are working. The manual starts a new rider "using rear-wheel drive only", and its display carries a "Drive Mode" indicator.

The front wheel of the Freesky Cheetah: the four-piston caliper, the disc rotor and the front hub motor behind them

Up front, the four-piston caliper and rotor sit ahead of the second hub motor.

Assistance comes from a cadence sensor: once the cranks turn, the motors add help at the level you pick from 0 to 5, and the throttle moves the bike with no pedaling at all. The manual's first ride is gentle: "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."

On easy flat miles one motor draws less; on climbs two draw less. Pedaling easily at 12 mph, one motor uses 7.4 Wh a mile and two use 8.7; up an 8% grade at 10 mph on the throttle, one uses 124.5 and two use 95.7 (the one-or-two table).

The 48 V 60 Ah battery: 2,880 Wh, about 12 hours from empty

48 V × 60 Ah is 2,880 watt-hours, and Freesky's page prints the same figure itself: "a massive 60Ah removable battery (2880Wh)". Every range figure below starts from it.

Freesky's range band sets a ceiling on what each mile may draw from those 2,880 Wh:

Freesky's figure Watt-hours per mile it allows
200 miles on pedal assist 14.4
120 miles on pedal assist 24.0

2,880 Wh divided by each end of Freesky's band. The range section finds the steady ride that fits each row.

The side of the Freesky Cheetah's frame under the red tank cover, the view Freesky places beside its battery description

Freesky pictures this side of the frame beside its battery description; the pack is removable, and the manual covers charging it on the bike or off it.

Plan on about 12 hours to charge from empty. Freesky's comparison chart gives 8–10 hours, and the charger is a "US Standard 5A Smart Charger"; 60 Ah at 5 A is 12 hours by plain division, so treat the longer figure as the one to plan around and charge overnight with room to spare.

Keep it dry, and charge and store it at 50 to 77 °F. The manual says the bike "is not intended to be used and stored" below 32 °F or above 104 °F, allows charging only in that same span, and asks for charging and storage "in a dry location, between 50 °F – 77 °F". For days when you will not need every mile, Freesky's summer charging guide says "charging to 80–90% can reduce thermal and chemical stress."

How far the Cheetah goes: your range, one motor or two

With both motors on flat pavement, a 180 lb rider covers about 151 miles on a full charge at 15 mph on the throttle, 112 at 20 mph, and 219 at 15 mph with easy pedaling. Up an 8% grade at 10 mph on the throttle, the same charge lasts 30 miles on both motors and 23 on one.

To find your own figure:

  1. Choose your speed and effort in the first two tables.
  2. Set aside 168 to 206 Wh of the 2,880 for each 1,000 feet you climb on both motors (10 mph on the throttle, 4 to 10% grades), and run both on the climb (one motor or two).
  3. Correct for your load, a passenger included, and the temperature, then plan on 80% of the answer.

Every table works out one steady ride at a time, from Freesky's specifications, Bafang's published figures for a comparable 48 V geared hub motor, drum measurements of ten 26 × 4.00 fat tires standing in for the Cheetah's 20-inch ones, and a road-cycling power model validated on a real road. The formula and one worked ride close the section.

Does riding faster cut range? Miles at each speed

Speed is the biggest single cost on the flat. The charge that carries you 151 miles at 15 mph carries you 112 at 20, because at 20 mph the air takes about 2.4 times the power it takes at 15, the ratio (20 ÷ 15)³.

Speed, flat Per mile Full charge At an 80% charge
10 mph 14.4 Wh 200 mi 160 mi
12 mph 16.0 Wh 180 mi 144 mi
15 mph 19.1 Wh 151 mi 121 mi
18 mph 22.9 Wh 126 mi 101 mi
20 mph (the default limit) 25.8 Wh 112 mi 89 mi
25 mph 34.8 Wh 83 mi 66 mi
28 mph 41.2 Wh 70 mi 56 mi

Throttle only, both motors, flat pavement, a 180 lb rider, 77 °F. The last column starts from an 80% charge, the level Freesky's summer charging guide offers when the whole range is not needed. Rows above 20 mph price speeds beyond the limit the Cheetah starts with; the class section deals with them.

No habit these tables price adds more range on the flat than light pedaling: at 15 mph, 75 W from you stretches a full charge from 151 miles to 219. Easy pedaling here means 75 W from you, steady pedaling 150 W. Without the motors, 75 W would move this bike at about 8.4 mph on level pavement and 150 W at about 12.6, so pick the column that matches what you could hold on your own.

Speed, flat Throttle only Easy pedaling (75 W) Steady pedaling (150 W)
12 mph 180 mi 330 mi legs alone
15 mph 151 mi 219 mi 380 mi
18 mph 126 mi 161 mi 219 mi
20 mph 112 mi 135 mi 170 mi
25 mph 83 mi 93 mi 105 mi
28 mph 70 mi 76 mi 83 mi

Miles from a full charge, both motors, flat pavement, a 180 lb rider; at 15 mph easy pedaling draws 13.2 Wh a mile against 19.1 on the throttle. In the 330- and 380-mile cells your legs out-push the motors, so those figures lean hardest on the model's least certain part, its motor losses at light load (Limitations item 5). "Legs alone" means 150 W holds 12 mph with the motors idle.

Your assist level is only the controller's rule for how much it adds while you pedal. Whichever level you ride, read the row for the speed you hold and the effort you give; the manual says as much for hills: "Use lower PAS levels and pedal when climbing hills."

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

Shift for your legs; choose your motors for the battery. Each motor turns with its wheel whatever gear you are in, so a shift changes your cadence and nothing more. How many motors run does change the draw:

Your ride One motor Both motors Both vs one
15 mph, flat, throttle 18.7 Wh 19.1 Wh +2%
20 mph, flat, throttle 26.1 Wh 25.8 Wh −1%
12 mph, flat, easy pedaling 7.4 Wh 8.7 Wh +18%
10 mph, 4% grade, throttle 58.6 Wh 49.8 Wh −15%
10 mph, 8% grade, throttle 124.5 Wh 95.7 Wh −23%
10 mph, 8% grade, easy pedaling 101.9 Wh 80.4 Wh −21%

Watt-hours from the battery per mile, a 180 lb rider. "One motor" is the rear motor alone with the front hub freewheeling, the rear-wheel drive the manual starts new riders on; "both motors" shares the push evenly.

On a climb the second motor pays for itself. A motor's winding loses energy in proportion to the square of its current, so two motors each carrying half the current waste much less than one carrying all of it: 95.7 Wh a mile against 124.5 up an 8% grade at 10 mph, which is 30 miles of climbing from a full charge instead of 23.

On gentle flat miles the arithmetic tips the other way, if only slightly, because a turning motor carries friction and magnet losses however lightly it is loaded.

Pedaling easily at 12 mph, that overhead shows as 8.7 Wh a mile against 7.4. On the throttle the two modes stay within 5% of each other from 10 to 20 mph, and at 25 and 28 mph both motors come out 3 and 5% ahead of one.

So the working rule is one motor for easy, level riding and both for hills, loose ground and higher speeds, and Freesky's manual already starts you on the rear motor.

Does going uphill drain the battery faster?

Yes: at 10 mph on the throttle up 4 to 10% grades, each 1,000 feet of climbing takes 168 to 206 Wh more on both motors than the same distance on level ground, and 212 to 289 Wh on one. Lifting the rider and the bike is 55 to 68% of that on both motors; the motors and the pack lose the rest, a share that grows as the grade steepens.

A 180 lb rider on the 122 lb Cheetah is 302 lb, and raising 302 lb by 1,000 feet takes 114 Wh at the wheels.

At 10 mph up an 8% grade on both motors the battery spends 193 Wh per 1,000 feet, so the whole 2,880 Wh would lift you about 14,930 feet with nothing kept for the flat. The model credits nothing for descents, and because a descent costs less than a level mile, a climbing budget built from these rows errs on the generous side.

Grade Per mile, both motors Full charge, both motors Full charge, one motor
2% 31 Wh 93 mi 86 mi
4% 50 Wh 58 mi 49 mi
6% 71 Wh 40 mi 32 mi
8% 96 Wh 30 mi 23 mi
10% 123 Wh 24 mi 17 mi
12% 152 Wh 19 mi 14 mi
15% 202 Wh 14 mi 10 mi

Throttle only at 10 mph, a 180 lb rider; the last column runs the rear motor by itself. The model holds each motor to a comparable motor's rated 1,000 W, so it prices the energy a climb costs; how fast the Cheetah holds a grade depends on motors Freesky rates at 2,000 W peak, so no hold speed is printed.

Price a hilly ride as its level miles plus its climbing. Forty flat miles at 15 mph on the throttle take about 762 Wh, and 3,000 feet of 8% climbing on both motors adds about 579, near 1,341 Wh of the 2,880 in all. Stops, starts and wind come on top, since the model rides each mile at a steady pace.

Does rider weight affect range?

Weight costs a little on the flat and a lot uphill. A heavier load raises the cost of the tires and the hill but not of the air, so the gap widens on a climb, and a passenger is weight like any other.

You plus your load 15 mph flat, throttle 20 mph flat, throttle 8% climb, 10 mph
130 lb 162 mi 117 mi 37 mi
180 lb 151 mi 112 mi 30 mi
300 lb 130 mi 99 mi 20 mi
400 lb 116 mi 91 mi 15 mi

Everyone and everything on the bike, with the bike's own 122 lb added in each row because the motors move it as well; both motors, throttle only. The 400 lb row is Freesky's full load capacity, a figure Freesky's own guidance counts as rider and cargo, so two riders and their gear fill it.

Going from 180 to 300 lb takes 21 miles off the level 15 mph ride, 151 down to 130, and on the 8% climb the 30-mile charge becomes a 20-mile one. Two-up at the full 400 lb, the level 15 mph ride still covers about 116 miles, while the 8% climb drops to 15, because on a grade most of the power at the wheels goes into lifting.

Does cold weather drain the battery?

Yes, and each colder step costs more. At 32 °F the easy-pedaling 15 mph ride that reaches 219 miles at 77 °F comes down to about 167. The manual sets 32 °F as the floor for riding, storing and charging, so the 14 °F row describes a day Freesky rules out.

Air Pack energy vs 77 °F 15 mph, easy pedaling 20 mph, throttle
95 °F 99% 232 mi 116 mi
77 °F 100% 219 mi 112 mi
68 °F 98% 206 mi 106 mi
50 °F 93% 182 mi 96 mi
41 °F 91% 173 mi 92 mi
32 °F 89% (80–93) 167 mi (150–175) 89 mi (80–93)
14 °F · below Freesky's floor 82% (40–83) 151 mi (73–151) 80 mi (39–81)

Flat pavement, both motors, a 180 lb rider. The central figure is the energy recomputed from McMaster University's LG HG2 cell data at a 0.5C discharge; 77, 50, 32 and 14 °F were measured and the rows between are interpolated, with the cells taken to be at air temperature.

The brackets show where published cell data disagree. The low end is the lowest capacity Samsung's data sheets print at that temperature for discharges of one to four times capacity an hour (the 25R and 30Q at 32 °F, the 35E at 14 °F); the high end is the most energy Casado and colleagues measured at a gentler rate in 2025.

Freezing air hits three ways at once. The cells return about 89% of their 77 °F energy (80 to 93% across the sources), and the air is about 9% denser, by the gas law the U.S. Standard Atmosphere uses.

Cold tires are the third. The model moves rolling resistance by 0.5% for every °F (0.9% per °C) away from 77 °F, up when colder and down when warmer, a rate between Rothhämel's fit for a 42 mm tire and Bicycle Rolling Resistance's road-tire average, and holds the 41 °F value below 41 °F.

At 95 °F the model edges past its 77 °F figure: warm rubber and thin air give back more than the 1% of energy the cells lose.

Do fat tires cut range? Tires and riding position

On level ground the tires move your range more than the motor choice does. Bicycle Rolling Resistance's drum put ten 26 × 4.00 fat tires between 23.2 and 42.1 W at 12 psi, 18 mph and a 94 lb load. It has measured no 20-inch fat tire, so the model borrows the median of the ten, a coefficient of 0.0105, for the Cheetah's 20 × 4 CSTs.

Rolling resistance 15 mph, throttle 15 mph, easy pedaling 20 mph, throttle
0.0070 · lowest of ten 175 mi 270 mi 124 mi
0.0105 · median of ten (used here) 151 mi 219 mi 112 mi
0.0126 · highest of ten 140 mi 196 mi 105 mi

Miles from a full charge, both motors, flat pavement, a 180 lb rider. The lowest of the ten is Schwalbe's Jumbo Jim LiteSkin and the highest Kenda's Juggernaut Pro, which the site lists at 0.01262.

Run the tires at the manual's pressure, "Freesky recommends 16-20 PSI for the stock tires", firmer than the drum's 12 psi. Sand, dirt and gravel have no drum figure, so send us the route and we will price a trail ride before you plan one from these rows.

Posture starts to count as the speed climbs. Tengattini and Bigazzi measured 37 upright cruiser riders at 0.640 m² of drag area, the value this model uses for the Cheetah's moped seat, and 90 everyday mountain-bike riders at 0.603 m², which would take the 20 mph throttle ride from 112 miles to 116.

Freesky's 120 to 200 miles, matched to real rides

Freesky's one band, 120 to 200 miles on pedal assist, covers a wide spread of steady rides. The manual says what such figures are: "The listed range and top speed of the bike are estimates, not guarantees of performance."

  • 200 miles allows 14.4 Wh a mile: about 10.0 mph on the throttle with both motors, 15.8 mph with easy pedaling, or 18.7 with steady pedaling, all on flat pavement.
  • 120 miles allows 24.0 Wh a mile: about 18.9 mph on the throttle with both motors, 21.5 with easy pedaling, or 23.5 with steady pedaling.

On one motor the throttle speeds barely move, 10.9 mph at the 200-mile end and 18.8 at the 120, because the modes sit within 5% of each other on the flat. Freesky's band therefore lines up with gentle pedaled rides at its top end and with throttle riding close to the 20 mph limit at its bottom.

Plan on 80% of any figure here: 80% is where Freesky's charging guide suggests stopping when you will not need the whole range, and it leaves a 20% reserve. On the throttle at 15 mph, that turns 151 miles into 121.

Find your row, then plan on 80% of it. Allow 168 to 206 Wh of the 2,880 for each 1,000 feet of climbing on both motors at 10 mph, with both running on every hill. On level pavement a 180 lb rider's plan is 121 miles at 15 mph on the throttle and 89 at 20.

Forty level miles at 15 mph and 3,000 feet of 8% climbing use about 1,341 of the 2,880 Wh on the throttle, well inside the 2,304 Wh an 80% charge holds. Email us your distance, your climbing, your weight with gear and any passenger, and your usual speed, and we will run the ride through the model before you order the $1,849 Cheetah.

How every figure here is worked out

A steady speed needs a steady supply of power at the wheels. Martin and colleagues' model, checked against riders on a road in 1998, gives that power in one line for a constant speed in still air:

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

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

Inside the bracket, the first term is the tires plus the hill and the second is the air, whose share grows with the cube of the speed once the bracket is multiplied by v.

Four steps separate the wheels from the battery:

  1. Your pedaling reaches the rear wheel through the chain at 97.7% efficiency, Martin and colleagues' figure, and the motors make up the rest.
  2. One motor or two: the rear motor carries the whole push in rear-wheel drive, and each carries half with both working.
  3. Each motor is modeled on the published figures of a comparable motor. Bafang's 2021 OEM workbook lists its RM G0H0 48 V geared hub with an n0 of 510 rpm and an nT of 426 rpm at a rated 1,000 W and an efficiency of "≥ 80" percent. Read as the no-load and rated speeds, those are 36.4 and 30.4 mph on Freesky's 24-inch wheel, so no row here runs faster than 28 mph. At the rated point the model uses 80%, and less when the load is lighter.
  4. The pack loses a little inside itself, by the battery efficiency Arango, Lopez and Ceren measured on a 48 V pack.

Then watt-hours per mile = battery watts ÷ mph, and miles = 2,880 Wh × the share of the pack's energy the temperature allows ÷ watt-hours per mile.

One ride, worked through: 15 mph on flat pavement on the throttle, both motors, a 180 lb rider. The tires take 94.9 W and the air 114.2 W, so the two wheels need about 209 W between them.

At 15 mph the wheels turn at 210 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 gives 4.8 N·m on 6.4 A at 75% efficiency, under its 80% because the load is light, and the pair draws 277.5 W.

Counting the pack's own losses, the battery supplies 285.9 W: 19.06 Wh a mile at 15 mph, and 2,880 ÷ 19.06 is 151.1 miles, or 120.9 from an 80% charge.

No measured ride of the Cheetah has been set against the whole chain; Limitations item 5 explains why and which inputs that leaves unchecked.

Brakes, lights and sound

Freesky fits "2.3T*180MM 4-piston Hydraulic Brakes" at both wheels, to stop a 122 lb bike that can carry 400 lb. The manual asks for both levers: "For optimal stopping performance, use both the front and rear brakes", because "Relying only on the rear brake will significantly increase your stopping distance."

The 800-lumen LED headlight sits behind a grille between the fork legs.

Freesky lists an "800 Lumen LED Headlight" and turn signals "Integrated into the handlebars" that work "with a simple press of a button", with the signal lamps at the tail on either side of the brake light.

The tail of the Freesky Cheetah: the red taillight between two amber turn-signal lamps

At the tail, the brake light sits between the two turn signals.

The LCD, in the page's words, "clearly shows 5 PAS levels, headlight status, speed, battery power, and mileage". To start the bike, the manual has you switch on the battery, then "use NFC to swipe the screen, or hold the power button and then enter the password" that the manual prints.

The Bluetooth speaker Freesky builds into the Cheetah's frame, lit, beside the red frame panel

The built-in speaker, which Freesky says connects to a phone "in seconds".

The Cheetah also plays music. Freesky describes "built-in HiFi Bluetooth speakers" that are "seamlessly designed into the frame", so you can stream from a phone while you ride.

A 120 mm fork, two coil shocks and 20 × 4 tires

Freesky specifies a "120 mm Oil-Sprung Front Fork" and a "Dual Coil Rear Shock", describing the pair at the back as absorbing "bumps and impacts" for "enhanced stability, comfort, and control".

The front of the Freesky Cheetah: the oil-sprung fork, the front mudguard and a 20 × 4 CST tire

A coil shock on each side carries the rear of the long seat.

The tires are 20 × 4" fat tires with inner tubes, inflated to 16 to 20 psi per the manual, above the 12 psi in the tire table. The rest of the running gear is a Shimano 7-speed derailleur on a KMC chain, an "Upgraded 6061 Aluminum" frame and an adjustable heavy-duty aluminum kickstand.

122 pounds and a 400-pound capacity

Freesky publishes 122 lb for the Cheetah, in its specification and again in its comparison chart, and a 400 lb load capacity.

The 400 lb covers whoever and whatever rides on the bike, a passenger included; the bike's own 122 lb is outside it. Freesky's hunting-bike guide defines the term plainly: "Remember that total payload includes the rider and cargo." A 180 lb rider and a 150 lb passenger with 40 lb of gear come to 370 lb, 30 lb inside it.

Two of Freesky's September 2025 posts about the Cheetah printed lower load figures, 300 lb and 350 lb, before the product page settled on 400. If two riders and their gear will come close to the limit, email us and we will get the figure confirmed by Freesky in writing before you order.

Plan for the bike's own weight too. Freesky's hunting-bike guide also says that at about 122 pounds the Cheetah "is not a lightweight e-bike", and that its size and weight "are worth considering if you frequently need to lift the bike onto a vehicle or maneuver it through tight areas."

Decide how the 122 lb will move when nobody is riding it. A ramp into a truck, a step up to a porch or a trip on a hitch rack may need two people and a rack rated for the weight, so settle the storage and the transport before you order.

Riding two-up: the seat, the footrests and the law

Freesky builds the Cheetah for two; the law where you ride decides whether two may ride it there. Freesky's page describes "tandem seating", "an extended, cushioned saddle designed for both rider and passenger", and "Dedicated foldable footrests for rear passengers".

The saddle Freesky describes as designed for both rider and passenger.

One of the folding footrests Freesky fits for a rear passenger.

States write the passenger rule in different words, and California's and Texas's show how far apart they can be.

California asks for a separate seat. Read on September 25, 2026, Vehicle Code § 21204(b) says: "An operator shall not allow a person riding as a passenger, and a person shall not ride as a passenger, on a bicycle upon a highway other than upon or astride a separate seat attached thereto."

California's Legislature has since widened that rule. AB 1614, approved by the Governor on June 30, 2026 as Chapter 40, Statutes of 2026, applies the same words on "a highway or a Class I bikeway, as defined in Section 890.4 of the Streets and Highways Code".

AB 1614 is not an urgency measure, so under article IV, section 8(c)(1) of California's constitution it takes effect "on January 1 next following a 90-day period from the date of enactment of the statute", which is January 1, 2027.

Texas asks what the bicycle was built to carry. Transportation Code § 551.102(b) reads: "A person may not use a bicycle to carry more persons than the bicycle is designed or equipped to carry."

Where The test in the statute What it asks of the Cheetah's seat
California, highways (Class I bikeways from January 1, 2027) The passenger rides "upon or astride a separate seat attached thereto" Whether one long saddle shared by two counts as a separate seat; the section does not define the term
Texas No more persons than the bicycle "is designed or equipped to carry" Freesky describes the saddle as designed for rider and passenger, and fits passenger footrests

Sources: Cal. Veh. Code § 21204, AB 1614 and Tex. Transp. Code § 551.102, read September 25, 2026.

Both rules are written for bicycles, and each state carries its bicycle rules to e-bikes: California's § 312.5(a) defines an electric bicycle as "a bicycle", and Texas's § 551.002 says a bicycle provision "also applies to ... an electric bicycle". They reach the Cheetah while it is ridden as an e-bike under the state's definition, which the class section sets out.

Neither statute mentions a moped-style seat, and § 21204 does not define "a separate seat". In California the long saddle can be read either way: as one seat two people share, which the words "a separate seat" do not describe, or as a seat with a place for each rider, built and sold for two.

Until a court or the Legislature settles it, a California rider who carries a passenger on the long saddle is relying on the second reading; in Texas the question is what the bike was designed for, and Freesky's own description answers it. For every other state, our 50-state e-bike law atlas prints the definitions, and our California and Texas pages set out those states in full.

Keep a passenger inside the numbers too. The 400 lb covers both of you and your bags, and the weight table shows the full 400 lb still covering about 116 miles at 15 mph on level ground. Before you carry anyone, check the rule on the roads and paths you will use, and email us if you want a second opinion on yours.

The Mercer fit test

The Mercers are a fixed family of seven that every bike we review is measured against, so the same questions get asked each time (meet the Mercers). Each verdict below rests on a figure Freesky publishes: the height range, the fixed 35-inch seat, the weight, the load capacity, or the age line in the manual.

Member Age · Height Verdict The number behind it
Frank Kowalski 63 · 5'10" Fits the range; the weight is his question 5'10" is inside 5'4"–6'5", but 122 lb is a lot to wheel into a garage, and with no step-through he swings a leg over the seat to mount
Ruth Kowalski 61 · 5'5" Check her inseam first 5'5" is one inch inside the range, and the seat stays at 35 inches, so her reach to the ground decides it
Jack Mercer 48 · 6'1" Fits, and can take a passenger where the law allows 6'1" is inside the range; with Dana behind him, the two of them and their gear must come to 400 lb or less
Dana Mercer 45 · 5'7" Fits as rider or passenger 5'7" is inside the range; as a passenger she uses the folding footrests Freesky fits
Maya Torres 32 · 5'6" Fits, if she can store and move 122 lb every day 5'6" is inside the range; for a car-free commuter the daily cost is the 122 lb, more than the range
Cole Mercer 16 · 5'11" Not until 18 He is tall enough, and the manual says: "Riders must be at least 18 years old."
Ivy Mercer 12 · — No The manual's 18-year minimum to operate it; she is on the table so the answer is here

Ruth and Jack show where the Cheetah divides a family. At 6'1", Jack clears every fit number and can share the seat if the two of them and their gear stay within 400 lb; at 5'5", Ruth is inside the height range yet has to check her inseam against a seat that will not come down.

Is it UL certified?

Freesky's page says the battery is. Under the heading "UL2271 Certified Battery", Freesky writes that its batteries "are rigorously tested to meet the UL-2271 safety standard", and its September 2025 post describes the pack as "UL-certified".

If a landlord, a building manager or an insurer asks for the certificate itself, email us and we will obtain the Cheetah's battery certificate from Freesky in writing before you order.

Has it been recalled?

No. On September 25, 2026 we searched the Consumer Product Safety Commission's recall database through a 623-record corpus built from bicycle, e-bike, battery and scooter terms, reading every field of every record, and queried the title, description, product-name and manufacturer fields directly for Freesky. No record names Freesky, and none of the 623 names Yansan Technology, the company on the cover of the Cheetah's manual.

The same run found the recalls it should have before its empty answer was trusted: Ancheer 1, Specialized 49, Trek 34.

The class question: 20 mph at every start, 40 mph published

Settle this before anything else, because Freesky gives the Cheetah two speeds. Its product page describes the motors "reaching up to 40 MPH via pedal assist and 20 MPH with the throttle", its comparison chart says "40 MPH (Throttle & PAS)", and the FAQ further down the page reads:

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.

The manual adds the detail that matters day to day: "The default speed limit is 20MPH each time the machine is turned on."

So there are two machines in one box: the Cheetah as it starts every time, helping up to 20 mph, and the 40 mph machine Freesky also describes, which its own FAQ ties to a license, plates and insurance.

The name describes the look. A moped-style e-bike keeps working pedals under a motorcycle-like body, and the law sorts it by its motor and its speed, the same lines California draws for any e-bike.

Read on September 25, 2026, California Vehicle Code § 312.5(a) defines an electric bicycle as a bicycle "equipped with fully operable pedals and an electric motor that does not exceed 750 watts of power".

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", while class 3 assists "only when the rider is pedaling" and "ceases to provide assistance when the bicycle reaches the speed of 28 miles per hour".

Federal law describes a low-speed electric bicycle in 15 U.S.C. § 2085(b) as "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 Cheetah sits
As it starts, assist and throttle stop at 20 mph California's class 2 throttle stops at 20 mph 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 and a class 2 throttle at 20 Past both speed lines, where Freesky's FAQ calls for a license, plates and insurance

Sources: § 312.5(a)(2) and (a)(3), Freesky's product page and the manual, read September 25, 2026.

Ask us for the continuous motor rating. Freesky lists "2000W + 2000W Peak Motor", a peak figure for each motor. California's text says "does not exceed 750 watts of power" and the federal text "less than 750 watts", and neither says whether peak or continuous output is meant.

Where the watt line applies to you, email us and we will get the Cheetah's continuous rating from Freesky in writing before you order. Our 50-state e-bike law atlas prints each state's definition.

Check your cover as well. The manual says "your insurance policies may not provide coverage for accidents involving Freeksy eBikes" and tells you to "contact your insurance company or agent" to find out.

Each time you switch it on, the Cheetah helps only up to 20 mph, and Freesky's FAQ links anything faster to a license, plates and insurance. Look up your state's definition and your trail manager's rule before you ride, and ask us for the continuous motor rating in writing if a 750 W line applies.

Where you can ride it

Off pavement, the land manager decides whether the Cheetah is allowed, and federal land managers start from the e-bike classes, so the 20 mph start-up limit and the watt line both count.

On National Forest land, the Forest Service's final e-bike directives of 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 records.

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

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

The ground you have in mind Who sets the rule The document 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 for that trail
Your own land, or land you are allowed to ride the owner the owner's permission

Each of the four answers to a different document, and none of them is a spec sheet.

On a National Forest the stakes are set in 36 CFR 261.1b: a violation of the part's prohibitions carries "imprisonment of not more than six months or a fine in accordance with the applicable provisions of 18 U.S.C. 3571 or both". Our public-land e-bike guide takes each federal agency in turn.

Red flags

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

  • Wrong if the bike must be lifted often. At 122 lb, steps and hitch racks may need two people; email us the stairs or the rack and we will point you to a lighter bike on our shelf. Our Smartravel Rocket ST201F review covers a moped-style bike at 104.1 lb, with the stops counted at your height.
  • Wrong if you need to touch the ground easily at a stop. The seat stays at 35 inches; send us your inseam and we will find a bike with a lower seat on our shelf. For two motors on a 33-inch bench, our Smartravel Raptor ST202 Pro review prints how many riders of each height sit with both feet flat.
  • Wrong for short, flat trips. A 2,880 Wh pack is built for distance; our hub-drive picks match single-motor bikes to short commutes.
  • Wrong for a rider younger than 18. The manual's minimum age to operate it is 18; our 50-state law atlas sets out each state's age rules, and we will suggest a bike a teenager can ride.
  • Wrong if you mean to ride public roads above 20 mph without a license. Freesky's FAQ requires a license, plates and insurance past 20; email us and we will point you to a bike built inside your state's class limits.
  • Wrong if a passenger rule where you ride calls for a separate seat. The passenger section sets out California's wording; check yours in our law atlas, and ask us before you plan to ride two-up.
  • Wrong if you want assist that follows how hard you pedal. Its cadence sensor reacts to the cranks turning rather than to how hard you push; our e-bike motor guide sets out both sensor types, and we can suggest a torque-sensing bike from our shelf.
  • Wrong for trails open to Class 1 bikes only. The throttle rules it out there; our public-land guide quotes each agency's wording, and we will check your trail with you.

Buy it if / Buy something else if

Buy it if you want long rides from one charge, 151 miles computed at 15 mph on the throttle; you ride dirt roads, gravel, your own land or long rural routes; you want a seat and footrests for a second rider where your state allows it; you are 18 or older, 5'4" to 6'5" and at home on a 35-inch seat; and you can keep a 122 lb bike dry and charged at 50 to 77 °F.

For $1,849 you get two 2,000 W peak hub motors, a 2,880 Wh pack, full suspension, four-piston hydraulic brakes, lights and signals, and a built-in speaker. On our listing, Shop Pay's sample plan is $166.89 a month for 12 months at 15% APR, $2,002.68 in total, subject to an eligibility check.

Owners on Freesky's page rated the Cheetah 4.8 out of 5 across five reviews as of September 25, 2026, and one of them wrote: "If you're looking for a dual motor long range moped style ebike this is one I put at the top of your list."

Buy something else if your trips are short and flat, where our hub-drive picks fit a single motor to the job, or you need a seat low enough to put both feet down; if your trails allow Class 1 bikes only, email us the trail system and we will match a bike to its rule. Our e-bike reviews hub gathers every review we have published.

Before you buy: the checklist

Nine checks before you spend $1,849; the first three tell you whether the Cheetah is yours to ride at all.

  1. Look up the rules for where you will ride: your state's e-bike definition for roads and paths, and the land manager's for trails.
  2. Confirm the rider is 18 or older, the manual's minimum.
  3. If you will carry a passenger, read your state's passenger rule (the passenger section has California's and Texas's).
  4. Ask us for the continuous motor rating in writing if a watt line governs where you ride.
  5. Measure your inseam against the fixed 35-inch seat, and your height against 5'4" to 6'5".
  6. Add up everyone and everything that rides on it and keep the total at or under 400 lb; the bike's own 122 lb is not part of that sum.
  7. Plan the storage and the lift: where the bike will live, and how 122 lb gets up a step or onto a rack.
  8. Find your ride in the range tables, plan on 80% of it, and run both motors on climbs.
  9. Choose a charging spot that stays dry and between 50 and 77 °F, and allow about 12 hours from empty.

Frequently asked questions

How far can the Freesky Cheetah go on one charge?

Freesky's figure is 120 to 200 miles on pedal assist. On our computation for a 180 lb rider on flat pavement with both motors on, a full charge covers about 151 miles at 15 mph on the throttle, 112 at 20 and 219 at 15 with easy pedaling. At 10 mph up 4 to 10% grades, climbing adds 168 to 206 Wh for every 1,000 feet; the range tables break it down.

How fast does the Freesky Cheetah go?

It starts limited to 20 mph every time it is switched on, as the manual says. Freesky's page publishes 40 mph on pedal assist, and its FAQ says going past 20 mph requires "a license, license plates, and insurance".

At its start-up setting its assist and throttle stop at 20 mph, where California's class 2 throttle must stop; each definition also draws a 750 W line and Freesky lists peak output, so ask us for the continuous rating in writing. At the published 40 mph it passes every class's speed line, and Freesky's FAQ calls for a license, plates and insurance.

What is a moped-style e-bike?

An e-bike with working pedals under a motorcycle-like body and a long seat, which is how Freesky's comparison chart files the Cheetah. The style does not decide the category: state definitions sort e-bikes by motor power and speed (the class section).

Should you get an e-bike or a moped?

The law draws that line by speed and power rather than by look. The Cheetah as it starts is inside the 20 mph line California sets for a class 2 throttle; ridden at the 40 mph Freesky publishes, its own FAQ asks for a license, plates and insurance.

Can two people ride the Freesky Cheetah?

Freesky builds it for two, with a saddle "designed for both rider and passenger" and folding rear footrests, inside a 400 lb load for both riders and their gear. Whether two may ride depends on your state: California requires the passenger to ride on "a separate seat", Texas limits a bicycle to the persons it is "designed or equipped to carry" (the passenger section).

How does carrying a passenger change the range?

Weight costs little on the flat and a lot on hills. At the full 400 lb, two riders and their gear, a full charge covers about 116 miles at 15 mph on level ground against 151 for one 180 lb rider; up an 8% grade at 10 mph it covers 15 miles against 30 (the weight table).

Is a dual-motor e-bike worth it?

For hills and loose ground, the model says yes: up 4 to 8% grades the Cheetah's two motors use 15 to 23% less battery a mile than one. On easy level miles the rear motor alone uses slightly less, and the manual starts new riders on rear-wheel drive.

How much does the Freesky Cheetah weigh?

122 lb, the figure Freesky publishes in its specification and its comparison chart. The riders and their gear come on top of it, and the weight table includes the bike in every row.

What is the Cheetah's weight limit?

Freesky lists a 400 lb load capacity, for everyone and everything the bike carries. Its hunting-bike guide says "total payload includes the rider and cargo", so the Cheetah's own 122 lb is not counted in the 400.

What rider heights fit the Freesky Cheetah?

Freesky publishes 5'4" to 6'5" and an inseam of 27 to 35 inches, on one frame whose seat stays at 35 inches with a 28.7-inch standover.

How long does the Cheetah battery take to charge?

Allow about 12 hours from empty. Freesky's comparison chart says 8–10 hours on its 5 A charger, and 60 Ah at 5 A is 12 hours by division. The manual asks for charging in a dry place between 50 and 77 °F.

How much is the Freesky Cheetah?

$1,849 in Red on September 25, 2026, the same on our store and Freesky's, with $3,049 shown as the regular price on both; shipping is free within the contiguous United States.

Can I finance the Freesky Cheetah?

Yes, with Shop Pay on our listing: the sample plan on September 25, 2026 was $166.89 a month for 12 months at 15% APR, $2,002.68 in total, subject to an eligibility check by Affirm's lending partners. The listing shows the plan you are offered before you pay.

What warranty does the Cheetah have?

Bought from us, a fault comes to us: send photos or video with your order number, and our listing says we "file and manage the claim with Freesky on your behalf" (buying it from us). Email us before you order and we will get the warranty terms for your order confirmed by Freesky in writing.

Where do I find the Cheetah manual?

Freesky's manual page lists a "Cheetah MT-380 User Manual", the PDF quoted throughout this review, covering assembly, start-up, the display, tire pressure, temperatures and the warranty.

Is Freesky legit?

Look at the record for this bike: no CPSC recall record names the brand as of September 25, 2026, the figures this review computes from are printed on Freesky's own page, and the Cheetah's manual carries the name Yansan Technology on its cover. The verdict says who the Cheetah suits.

Limitations of this review

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

  1. We sell this bike. Read the red flags with the same attention 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 section cites, or arithmetic on this page.
  3. Each range figure is for a steady ride: one speed on one grade with no wind and no stops. Stops, starts and headwinds cost more, and a tailwind less.
  4. Bafang's figures stand in for Freesky's motors. Freesky gives peak output, 2,000 W, and 120 N·m per motor; the model uses Bafang's published figures for a 1,000 W 48 V geared hub, reading its n0 and nT as the no-load and rated speeds. On the 24-inch wheel those are 36.4 and 30.4 mph, below Freesky's 40, so no row passes 28 mph and no hold speed on a grade is printed. At 82% efficiency in place of Bafang's 80% floor the 15 mph throttle figure moves from 151 miles to 169; on Bafang's 750 W version it is 154.
  5. No measured ride checks this model. The physics reproduces Martin and colleagues' worked example and the motor reproduces Bafang's 80% at the rated point, but the Cheetah reviews we found on YouTube report speeds and short rides, one of 11 to 12 miles, and none a range test. On Freesky's page one owner reports 90 km, about 56 miles, "throttle only and more or less full speed", with a photo of the display whose battery gauge is a little over half lit; the model's 20 mph throttle row spends about half the pack over 56 miles, but a bar gauge reads in coarse steps and the review gives no speed, load or weather, so it is a consistency check, not a measurement. No measured hub-motor map was available to check the motor model at light loads either.
  6. The model shares the push evenly between the motors with both on, and lets the front hub freewheel with one on, as a geared hub's clutch allows. Freesky calls them hub motors without saying geared or direct drive, and nothing Freesky publishes says how the controller splits torque.
  7. Every figure assumes Freesky's 2,880 Wh. The documents read here do not say how much of the pack the battery management system releases; on one measured pedelec, researchers at KIT found 75% used in a standard range test.
  8. The tire coefficient is borrowed from 26-inch tires. No drum figure exists for a 20 × 4 fat tire in the tables read, so the model uses the median of ten 26 × 4.00 tires at 12 psi, and the tire table brackets it with the lowest and highest.
  9. The cold figures rest on one cell's laboratory data. Freesky does not name the cells, 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. Where Freesky's documents differ, this review follows the product page read on September 25, 2026. Freesky's September 5, 2025 post about the Cheetah gives 77 lb, a 300 lb load, a 2,640 Wh pack, 60 miles on electric power and 90–120 with pedal assist, 6–8 hours of charging, an 80 mm fork, 38 mph and a 5'2"–6'1" rider range; its September 8 post gives a 350 lb load, 90–150 miles and 100 N·m per motor; its October 3 post gives up to 200+ miles, 38 mph and a 1,000-lumen headlight; and its May 2026 buyer's guide lists the Cheetah among bikes with "dual-battery systems", where the product page describes one "60Ah removable battery". On request we will get any of these confirmed by Freesky in writing.
  11. Smaller rows differ the same way. The page specifies a thumb throttle while the manual describes rotating the throttle "backward toward the rider". The page's feature list reads "40 MPH via pedal assist and 20 MPH with the throttle", while its comparison chart says "40 MPH (Throttle & PAS)" and the product record's feature list "40 MPH by Pedal Assist or Throttle". The record also carries 108 lb in its variant weight field, against the 122 lb the page publishes. No range figure depends on these rows.
  12. The passenger question in California is open. Section 21204 does not define "a separate seat", this review did not research case law on moped-style saddles, and the manual's text says nothing about passengers. Treat the passenger section as the statutes' words, not a ruling.
  13. Trail access is set locally. Your land manager's rule decides, it can change, and neighboring systems differ; this page does not replace it.
  14. 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. Freesky's manual-download page, read September 25, 2026, lists UL certificates for other models and none for the Cheetah.
  15. Stock and price were read on September 25, 2026, and both can change.

The bottom line

For $1,849, the Cheetah puts a 2,000 W peak hub motor in each wheel of a full-suspension, moped-style fat-tire bike with a 2,880 Wh pack, four-piston hydraulic brakes, lights, signals, a built-in speaker, and a seat and footrests for a passenger.

On level pavement a 180 lb rider gets about 151 miles at 15 mph on the throttle, and two riders at the full 400 lb about 116; on 4 to 8% climbs at 10 mph both motors use 15 to 23% less battery a mile than one.

It suits long rides on dirt roads, gravel, rural routes and your own land, for riders 18 and over between 5'4" and 6'5" who are comfortable on a 35-inch seat and can handle 122 lb. Through Shop Pay on our listing it comes to $166.89 a month over 12 months at 15% APR, $2,002.68 in total, subject to an eligibility check.

Before you pay, settle the class and the passenger: the bike starts limited to 20 mph every time, Freesky publishes 40, and on Freesky's own account anything faster needs a license, plates and insurance. Tell us where you will ride, and with whom, before you order, and we will get Freesky's continuous motor rating in writing if a watt line applies.

One colorway, Red, at $1,849. Shop Pay can spread it over 12 months at $166.89 a month and 15% APR, subject to an eligibility check; shipping is free within the contiguous United States, and if it arrives damaged we file the carrier claim for you.
