Ridstar E26 Pro Review: 2 Motors, 1 UK Safety Report

26 × 4.0 fat tires and suspension at both ends on a mountain e-bike with a hub motor in each wheel, 2000W together by Ridstar's count · 48V 23Ah (1,104 Wh) · 75 lb on Ridstar's fit image · named in UK product safety report 2506-0011 for its charger · our E26 Pro listing sold out at $826.85 · verified October 25, 2026

Quick Answer — Our listing is sold out. The E26 Pro is Ridstar's 26 × 4.0 fat-tire mountain e-bike with a hub motor in each wheel, 2000W together, and a 48V 23Ah pack. Computed for a 180 lb rider holding 15 mph on the flat with no pedaling, the pack lasts 61 miles; Ridstar's text says 30 miles in electric mode.

Ridstar still sells it in the US from one of its two stores: on October 25, 2026, with the US market selected, ridstar.com's E26 Pro listing showed its US variant in stock at $1,489.00, while ridstar.net's read sold out at $719.00.

The identity section sets the two listings and ours side by side, and the verdict points you to three bikes in stock here that can take its place.

Read the maker's record before anything else. Britain's Office for Product Safety and Standards named the E26 Pro in report 2506-0011 of June 19, 2025, risk level "Serious", for its charger: "The import has been rejected at the border." That is a UK action on a UK shipment.

In the US, the Consumer Product Safety Commission's two Ridstar stop-use warnings, 26-337 and 26-584, name Q20 models and not the E26 Pro, and on October 25, 2026 the Commission's recall list held no Ridstar entry. The record section quotes all of it.

How we verified this Ridstar E26 Pro review

Every Ridstar figure on this page was verified against its two E26 Pro listings, ridstar.net's and ridstar.com's, with the US market selected on October 25, 2026, and every Ridstar photograph was opened at full size that day. Any figure we computed comes with its working in the section that prints it.

The same day we read the CPSC record, Britain's product safety report, two court dockets, Ridstar's parts catalog, four other sites selling under the Ridstar name, an owners' forum thread of 115 posts, the federal and California statutes this page quotes, and our own stock and checkout. Part of our e-bike reviews.

The E26 Pro's figures, as Ridstar printed them

Ridstar's two stores print three top speeds, six range figures, two rider windows, two brake descriptions and two warranties for the E26 Pro, from text that is otherwise word for word the same. Our reading leads each row, followed by Ridstar's own words and what its pictures show you.

Image 1 of ridstar.net's E26Pro gallery, image 3 of ours. The blue glow on the rims is in Ridstar's file; no Ridstar photograph of this bike shows the rims without it.

The bullets, description and "Technical Details" tab of ridstar.net's E26Pro listing, the bullets, slider and copy of ridstar.com's, and their images, among them the motor strip and the fit image, each read on October 25, 2026 with delivery to the US selected.

Three rows deserve your second read. The motor row and the top-speed row decide which vehicle class your state gives the bike, as the class section shows; the weight row is the one figure an owner disputes; and the rider-height row is two windows on one ridstar.com page, which the fit section sets against the printed saddle range.

Image 2 of ridstar.net's E26Pro gallery, image 4 of ours. Its "31MPH" sits three miles an hour over the "28+++ mph" of the text beside it.

Where Ridstar contradicts itself, you get both figures here, and the papers that come with your bike settle it; any calculation that needs a single number names the one it used.

Two stores, one machine: what the E26 Pro is

The E26 Pro is a full-suspension fat-tire mountain e-bike on 26 × 4.0 tires with a hub motor in each wheel, a rear rack and a battery in the down tube, sold under one listing on each of Ridstar's two stores. Our own listing read sold out on October 25, 2026.

Prices are in US dollars, read October 25, 2026 with the US market selected on every page; creation dates come from each store's own product record. ridstar.net lists $1,699.99 as a compare-at price beside its $719.00, and ridstar.com $1,789.00 beside its $1,489.00.

Whichever store you read, the two describe one machine. Their "About this item" bullets, on ridstar.net and ridstar.com, match word for word except the warranty line, and each store's text and photographs were the same on October 25 as on the copies we took on August 26, 2026.

Five of our listing's photographs are ridstar.net's five E26 Pro photographs; two more are Ridstar photographs of a different bike. The cockpit close-up and the front view of the bars on our listing are the photographs Ridstar runs for its E26, a 1000W model shown in gray.

Three others match none of the E26, DC26, H26 Pro or MN26 photographs on either Ridstar store, so you will not find any of those five on this page as the E26 Pro.

The first photograph on ridstar.com's E26 Pro listing, the bike's left side; ridstar.net's lead shows its right.

Asked on the Endless Sphere forum whether the bike folds and what it weighs, an owner answered on December 6, 2024: "That's the bike I have. It does not fold. It weighs just under 100lbs." Ridstar's fit image prints "75LBS"; both figures are on this page, and the range tables run on Ridstar's.

The "folding" in the web address of ridstar.net's listing, and of ours, appears in neither store's title, text or photographs, and that owner's answer agrees: you should plan on lifting a full-size frame.

If you already own one, ridstar.net's parts store sells E26 Pro spares under options spelled "US / E26 PRO", "US / E26PRO" or "US / E26Pro", among them a charger at $69.00, a front fork at $189.00, a front wheel nut kit at $25.00 and a battery at $499.00. The record section says which of those listings also sell Q20 parts.

Who the E26 Pro fits: a 33.8 to 38.5-inch saddle and two height windows

Ridstar's fit image puts the E26 Pro's saddle top 33.8 to 38.5 inches off the ground, so with an inseam over 35.3 inches the top setting sits below the 109%-of-inseam pedaling height whatever the pedal height. In the US Army's ANSUR II body survey, that inseam belongs to at least 58 of every 100 riders at 6'1" and 97 of 100 at 6'4".

If your inseam is under 35.3 inches, the top setting can still come up short by however high the pedal sits off the ground, a figure Ridstar does not print.

ridstar.com's E26 Pro page prints two rider windows for its one frame size: "Recommended Height 5'7" -6'7"" on the slider, and "5.3-6.3FT" on the fit image below. Taken as decimal feet, the image's window is 63.6 to 75.6 inches and opens 3.4 inches under the slider's; taken as feet and inches, it is 5'3" to 6'3".

Your fit, in three steps:

1. Take off your shoes, stand with your back flat to a wall, and lift a hardcover book, spine up and level, until it sits firmly in your crotch; mark the wall at the top of the spine and measure from the floor to that mark: that is your inseam.
2. Over 35.3 inches, the top-setting table is your answer; at any inseam, the saddle table gives the pedaling height your legs want.
3. When the bike arrives, set the saddle with the heel check, and if the post runs out first, you know the change you need.

Image 6 of ridstar.com's E26 Pro gallery; neither ridstar.net's listing nor ours carries it. Arrow H runs from the ground to the top of the black saddle, 33.8 inches, and arrow I to the top of the gray one above it, 38.5.

An owner's account points the same way. Describing themselves as "just over 6 ft maybe 6'2" in boots", an E26 Pro owner wrote on Endless-Sphere in May 2025 that "this bike is a little taller than is actually comfortable for me", adding: "I have the seat all the way up for proper leg geometry but then I can't even come close to touching the ground from the seat."

Will the E26 Pro's saddle go high enough for me?

Each row gives you a saddle height for the median leg at that height three ways, all counted from the axle of the lower pedal up to the saddle's top. The middle figure is the 109%-of-inseam rule, which Peveler et al. (2005) compared with the heel method; the outer two are 106% and 110.4%.

Both outer figures are from Ferrer-Roca et al. (2012): their recommended range begins at 106%, and the range their own equation produces ends at 110.4%, so reading the two as one band is our step. At each height, the inseam span covers the 5th through the 95th percentile of the 6,068 soldiers in the Army's ANSUR II survey.

Pedal axle to saddle top, by rider height: 109% of the median inseam in the third column, 106% and 110.4% in the last two. Heights with fewer than 30 surveyed bodies have no row. No crank length appears in Ridstar's E26 Pro figures, which leaves LeMond's 88.3%, a crank-axle formula, with nothing to work from here.

Ridstar's 33.8 and 38.5 inches start at the ground; the distances above start at the pedal, which at the bottom of its stroke sits some way off the ground. At any setting, then, your saddle stands less than its printed figure above the pedal, and the table below counts only the riders that fact settles on its own.

Of 100 ANSUR II riders at each height: how many want more than 38.5 inches from pedal to saddle at 109% or at 106%, so the top setting cannot reach whatever the pedal height, and how many want 33.8 inches or more at 106%, so the lowest setting is certainly low enough. The first two are floors; outside the last count, the answer turns on the pedal height Ridstar does not print.

From 6'1" to 6'3", heights inside both of Ridstar's windows, the top setting falls short of 109% for more than half of riders. At 6'1" that is at least 58 of 100, and at least 24 of 100 come up short even at 106%; at 6'4" the counts are 97 and 94.

At the bottom of the range the count reads the other way. At 5'7", where the slider's window opens, the lowest setting is certainly low enough at 106% for 64 riders in 100, and at 5'4" for 8; for everyone else at those heights it may also be, depending on the pedal height.

Seven months before that post, in October 2024, the same owner had written about a replacement saddle "about two inches taller the the original" (sic) that "gives me perfect leg geometry with the seat post at full extension". A taller saddle or a longer post shifts every row, and your own heel check settles whether you need one.

Can I put a foot down at a stop?

Ridstar publishes no standover height for the E26 Pro, so the gap between you and the top tube when you straddle the bike is not computed here. The fit image labels the top tube "C . 57cm-22.4in", a length along the tube, not a height above the ground, and nothing is measured off the drawing, for the reason the fit arithmetic gives.

Seated, the record is the owner above: at the top setting, "I can't even come close to touching the ground from the seat". Before your first ride, straddle the bike in socks to see the gap over the top tube for yourself.

Will you sit stretched or cramped on the E26 Pro?

Your lean to the bars is not computed here, because Ridstar's E26 Pro figures give no seat-tube angle, stem length or grip reach. Its one cockpit figure is vertical: the fit image's "B . 117cm-46in" puts the top of the bar 46 inches off the ground, 7.5 inches above the top saddle setting and 12.2 above the lowest.

ridstar.com's "Design highlights" say the E26 Pro "uses an adjustable saddle, height-adjustable handlebars", and give no range for either. The owner quoted above reported that "120mm riser bars made the bike much more comfortable for me", one rider's change at one height; send your arm length with your inseam if reach is your worry.

How much weight goes through your wrists?

The load on your hands is not computed for the E26 Pro, because it depends on a lean angle that Ridstar's figures do not give. The closest measurement in print comes from another machine: in a University of Colorado thesis, Carahalios (2015) recorded about 15% of body weight on the stem for ten road racers pedaling a stationary bike with their hands on the brake hoods.

The E26 Pro's bar stands 7.5 to 12.2 inches over its saddle, a different position from those racers', so that 15% is a reference point from another kind of riding, never a number for you on this bike.

How do you set the saddle when it arrives?

Turn a crank until it points straight down along the line of the seat tube, put your heel on that pedal, and raise or lower the saddle until the leg is straight with the heel still on it. That is the heel method the 109% formula was set beside. Ridstar's feature list calls the saddle an "Adjustable Seat", and ridstar.net's fifth gallery image gives it a panel, "ADJUSTABLE SADDLE", with arrows for up and down.

Then ride a few turns on the balls of your feet and watch the knee at the bottom. Peveler, Pounders and Bishop (2007) give 25 to 35 degrees of bend as the cycling literature's range there. Ferrer-Roca et al. (2012) treat 30 to 40 degrees as the optimal bend.

A post that tops out before your heel straightens the leg calls for a longer post or a taller saddle.

The fit arithmetic, step by step

All 6,068 bodies in ANSUR II go through two calculations: its inseam times 1.09, 1.06 and 1.104 gives the pedal-to-saddle distance it wants, and that distance is set against the 38.5 and 33.8 inches Ridstar prints for the top and bottom saddle settings.

Dividing 38.5 by 1.09 gives the 35.3-inch inseam above which the top setting cannot reach at 109%, and by 1.06 the 36.3-inch line at 106%; 33.8 over 1.06 gives 31.9 inches, the inseam from which the lowest setting is certainly low enough.

Worked through for 5'8": the survey's median inseam at that height, 32.6 inches, wants 35.6 inches from pedal to saddle at 109% and 34.6 at 106%.

That is under the 35.3-inch line, so the top setting reaches it only if the pedal axle at the bottom of its stroke sits no more than 2.9 inches off the ground, 38.5 less 35.6, and Ridstar prints no figure that settles it. At 106% it is over 33.8, so the lowest setting goes low enough.

Nothing is measured on the fit image, because its arrows do not agree with their own labels. Scaled to the 46-inch arrow from the ground to the bar, only the arrow between the axles lands within 3.5% of its printed length; the two saddle arrows come out 13.2% and 15.6% long, the overall length 6.5% short and the front-wheel arrow 38.3% short.

A drawing earns measurement here when three of its arrows agree within 3.5%.

The 109% figure has a check in the same 2005 paper: Greg LeMond's method, measured from the pedal, set its riders at 109.2 ± 0.9% of inseam. What the missing frame figures leave open is listed under Limitations.

Two hub motors, 1000W each and 2000W together

Ridstar gives the E26 Pro a brushless hub motor in each wheel and prints the pair three ways: "two brushless motors with a total power output of 2000W" in both stores' bullets, "2000W(1000W*2)" on ridstar.com's slider, and "Motors up to 2000W peak" in ridstar.com's copy. No continuous rating appears, no motor maker is named, and the one torque figure is "90NM" over "Torque" on the motor image.

You ride it three ways, by Ridstar's list: "pure electric, pedal-assist, and classic bike modes". The controls Ridstar names are a "Twist Grip Throttle" and a display with "a 5-speed mode", which one owner describes as "5 PAS settings". Neither store tells you whether one motor can be switched off; owners write that it can.

An owner on Endless-Sphere wrote in May 2025: "I mostly ride on just the rear motor just kicking the front on as needed for sloppy conditions or steep hills." A reviewer on ridstar.com's own listing put the difference this way: "having the second motor on doesn't make you go any faster you just reach the top speed faster".

Ridstar's top speed is "28+++ mph" in the bullets, "Max Speed 28 MPH" on the slider, and "a maximum speed of 31mph" in ridstar.com's copy and on the motor image; owners report higher.

The owner quoted above gives "33-35mph wide open on level ground" and pedal-assist steps of "1)13.3 2)18.4 3) 23.4 4) 28.5 5) 33-35mph"; another wrote "Top speed on mine is 34.1 mph", and the ridstar.com reviewer "my top speed is 30.7 mph".

The range model reads Ridstar's 31 mph as the speed the motors spin up to with nothing to push, and on that reading a 180 lb rider tops out at 28.6 mph on the flat. On current, Ridstar prints nothing; the record is one owner's reading of the display's settings, "the controller is set at 12 amps", with the remark that "12A times 48V is NOT 1,000 watts".

A 48V 23Ah pack: 1,104 Wh, and 4 to 6 hours on the charger

One removable pack feeds both motors: a "UL certified 48V 23Ah removable battery" in both stores' bullets and "48V 23AH Removable lithium battery" on ridstar.com's second image; multiplied out, Ridstar's 48 V and 23 Ah come to 1,104 Wh. Ridstar prints no watt-hour figure, no cell type and no cell maker, and the UL section sets its UL wording against the record.

The right half of image 2 in ridstar.com's E26 Pro gallery, cropped at native scale; its left half carries the motor figures of the motor image above. Its "4-6 HOUR" is the only charge time Ridstar gives the E26 Pro; neither store's text prints one.

Ridstar prints no charger output for this bike, so you cannot check the four to six hours against one: filling 23 Ah in 4 hours takes 5.75 A, and in 6 hours about 3.8 A. Ridstar's charger listing sells an "E26 PRO" option at $69.00, and its text names only two outputs, "Q20 Lite 48V15AH(2A)" and "Q20 48V20AH(3A)".

The charger is the part a UK regulator flagged. OPSS report 2506-0011 found that the wall-plug charger with three Ridstar models, the E26 Pro among them, "has poor quality soldering, and the transformer does not meet the minimum requirements for creepage and clearance distances"; the record section gives the report in full.

A spare costs $499.00. ridstar.net's battery listing, titled for the Q20, DC26 and H20 at 20Ah and 15Ah, sells a "US / E26Pro" option at that price and names no capacity for it, and YVY's twin listing prices its "US / E26 Pro" option the same; both showed available on October 25, 2026. Ask which capacity ships before you pay for one.

Ridstar sells the E26 Pro's throttle as a part with "two keys included", $59.00, and a would-be buyer on Reddit named its "key ignition" as the draw for leaving it parked on food deliveries.

Charging costs you little. At 18.16 cents per kWh, the US residential average in the Energy Information Administration's August 2026 figure, released October 23, an empty pack refills for about 20 cents before the charger's own losses; if you ride 1,000 miles a year at 15 mph on the motors alone, the model's 18.1 Wh a mile comes to about $3.28 a year.

Range: 61 miles at 15 mph, 27 at 28 mph

For a 180 lb rider on level pavement with no pedaling, the model gives the 1,104 Wh pack 61 miles at a steady 15 mph, 45 at 20 mph and 27 at 28 mph; at Ridstar's 330 lb load limit, 15 mph returns 51. Climbing at 10 mph on the motors alone costs about 128 Wh per 1,000 feet of rise on a 4% grade and 151 Wh on 10%, by Martin and colleagues' equation.

Three steps to your own number:

1. Open the speed tables, pick the row for your usual cruising speed and the column for how hard you pedal, then shift that figure for your weight and cargo.
2. Add the climbing on your route and, in winter, the cold row for your temperature.
3. Use the reserve column for planning: it keeps a quarter of the charge in hand.

All of it is arithmetic from one model: Ridstar's E26 Pro figures go in beside Bafang's published curve for a comparable hub motor and fat-tire rolling resistance measured on a drum, and the arithmetic subsection works a whole ride through.

How far does the Ridstar E26 Pro go on one charge?

On flat pavement with no pedaling, a 180 lb rider gets 82 miles at 10 mph, 61 at 15, 45 at 20 and 32 at 25. The first table ends with the planning column; the second adds your legs.

Watt-hours a mile and miles from a full 1,104 Wh pack at each steady speed: flat pavement, 77 °F, a 180 lb rider on the 75 lb bike, rolling resistance at the median of ten fat tires on a drum. The last column keeps back 25%, the share Schmitt, Decker and Doppelbauer (2019) found left unused when they ran a complete pedelec drive on a test bench; Ridstar names no reserve.

Full-pack miles with your legs adding 75 W (easy) or 150 W (steady), beside the motors alone, on flat pavement with a 180 lb rider and the 75 lb bike.

The tables stop at 28 mph. On Ridstar's 31 mph the model's top steady speed for a 180 lb rider is 28.6 mph, where a full pack lasts 25.9 miles, and each step up in speed costs miles: 32 at 25 mph, 27 at 28.

With the motors off, 75 W from your legs holds about 9.0 mph on the flat and 150 W about 13.1 mph. The effort table begins at 15 mph, where the motors still carry part of the load at either effort.

What do the E26 Pro's seven gears change?

Both stores sell "the Shamano 7-speed gear system" (sic), ridstar.net's Technical Details list "Number of Speeds 7", and ridstar.net's fifth image labels its shifter "7-SPEED"; ridstar.com's third image labels the same kind of panel "21-SPEED" over a shifter printed "SHIMANO 7SPEED".

A hub motor turns with its wheel rather than through the chain, so shifting changes how fast your legs spin, not what the pack spends; the table prices your effort instead.

Watt-hours a mile on four rides at three efforts, 180 lb rider, 75 lb bike: 15 and 20 mph on the flat, and 12 mph up 4% and 8% grades.

Easy pedaling at 12 mph up an 8% grade saves the pack 10.4 Wh a mile against the motors alone. One owner found the stock gearing short for pedaling at speed and swapped the "factory 14-28" freewheel for an 11-28: "So now I can pedal up to 28 in 7th gear with the motor also powering."

What a climb costs the E26 Pro's pack

Holding 10 mph on the motors alone, a mile of 2% grade costs 26 Wh, so a full pack lasts 42 miles of it; a mile of 15% costs 150 Wh, and the pack is empty in 7. With easy pedaling, each 1,000 feet of climbing costs 118 to 140 Wh between 4% and 10%.

Full-pack miles uphill at a steady 10 mph on grades from 2% to 15%, 180 lb rider, 75 lb bike: on the motors alone, and with 75 W of easy pedaling added.

Ridstar's own climbing figure is "conquer 45° hills" in its bullets and "45°" over "Gradient" on its second image. A 45° slope rises as far as it runs, a 100% grade, and Ridstar attaches no speed, load or length to it; this table stops at 15%.

On these rows the torque is not the limit. At 10 mph a 15% grade asks 71.3 N·m at the wheels, within the 90 N·m Ridstar prints for the pair, and 1,355 W from the pack, about 28 A at 48 V. The model splits that evenly between the motors, because neither store says how the controllers share it.

On steep ground the second motor is the point of the bike for its owners: "It hardly even slows down on seriously steep hills with both motors pulling", the May 2025 post reads, and an October 2024 post says the bike "without the front motor would be in a world of hurt with the hills and mud around here".

How many miles does a heavier load cost?

Loaded to Ridstar's "Maximum load capacity of 330 lbs", a full pack gives 51 miles at 15 mph on the flat with no pedaling, against 61 for a 180 lb rider; on an 8% climb at 10 mph, 15 miles become 8. Ridstar does not say what the 330 lb includes, so the model counts you and your cargo together against it.

Miles from a full pack for each total of rider plus cargo on the 75 lb bike, motors alone: 15 and 20 mph on flat pavement and an 8% climb at 10 mph. The last row is Ridstar's 330 lb.

Every table runs the bike at 75 lb, the "75LBS" "Product Weight" on ridstar.com's fit image and the only weight Ridstar prints for it. An owner answered a forum question about the weight with "It weighs just under 100lbs", so the model also runs 100 lb, the top of that report: 2 fewer miles at 15 mph on the flat, and 2 fewer on the 8% climb.

Ridstar's 75 lb against 100 lb, the ceiling of one owner's "just under 100lbs", for a 180 lb rider on the motors alone; every other table uses 75 lb.

Range in the cold

The 61 miles a 180 lb rider gets at 15 mph on a 77 °F day compute to 49 at 32 °F, bracketed 44 to 51, and 45 at 14 °F, bracketed 22 to 45. Ridstar names no cell, so the energy column borrows the published temperature behavior of LG's HG2, an 18650 cell.

The pack's energy at each air temperature as a share of its 77 °F value, and the miles it gives a 180 lb rider on the 75 lb bike at 15 mph on the flat, motors alone. At 32 °F and colder, each bracket covers the range of the published cell tests.

At 95 °F the cells give up 1% of their energy, yet the ride gains 2 miles over 77 °F, because rubber rolls more freely warm. Bicycle Rolling Resistance's temperature test measured an average 17.6% drop as a tire's surface warmed from 20 °C to 40 °C, about 0.88% a degree, and Rothhämel's (2023) climate-chamber work about 0.97%; the model takes 0.9% a degree Celsius and makes no correction below 41 °F.

The pack lifts out, so on winter days you can keep it indoors until you leave; every row assumes cells already at the outdoor temperature.

Fat tires and the way you sit

Swap in the best-rolling tire of the ten fat tires a drum test measured and 61 miles at 15 mph becomes 69; the worst-rolling one makes it 57. Ridstar's E26 Pro text never names a tire maker, a tread or a pressure; it says only "26"*4.0" puncture-resistant fat tires" for "grass, dirt, sand, snow, and gravel".

An owner names them: one post calls them "the chow yang's that came on it", and the October 2024 post reports putting "Flat Out in both tires after seeing so many complaints about how easy these tires puncture".

Your posture is the other big lever. Tengattini and Bigazzi (2018) measured 0.640 m² of drag area on upright cruiser riders, and the model uses it; ride leaning forward like their everyday mountain-bike group, at 0.603 m², and 15 mph on the flat reaches 63 miles.

Flat-pavement miles at 15 and 20 mph with the lowest, median and highest rolling resistance among ten fat tires on a drum, motors alone, 180 lb rider, 75 lb bike. The grass, sand and snow of Ridstar's copy are beyond a paved-road model.

Will the E26 Pro go Ridstar's 30 to 87 miles?

Across its two stores Ridstar states the E26 Pro's range six ways, and none comes with a speed, load or surface.

On ridstar.net the description reads "In electric mode, it offers a range of 30 miles, and with pedal-assist, you can go up to 50 miles"; both stores' bullets print "87 Miles Long Range" over "Pure electric range 50-75km, assisted range 70-90km"; ridstar.com's slider says "Max Range 50 Miles"; and its second image prints "25-47 MILES" over "Long range".

Run backward, the model finds the steady flat speed at which the full 1,104 Wh lasts exactly each distance for a 180 lb rider. "30 miles" in electric mode means holding 26.3 mph on the motors alone; "50 miles" means 18.2 mph, or 21 with easy pedaling; "87 Miles" means 8.9 mph on the motors alone or 15.2 with easy pedaling.

The steady flat-pavement speed at which a full pack would run out at each of Ridstar's figures, for a 180 lb rider on the 75 lb bike, at three efforts; a dash marks a distance the model reaches at no steady speed it can hold. Kilometers converted at 0.621 miles each; from ridstar.net's and ridstar.com's E26 Pro listings and ridstar.com's second image, read October 25, 2026.

The low "25" lies past the model: at its top steady speed, 28.6 mph, the pack still lasts 25.9 miles. Ridstar's 30 and 50 miles fit steady rides of about 26 and 18 mph with no pedaling; your own figure is in the speed tables, with the reserve column the one to plan on.

The range arithmetic, one ride at a time

Three forces hold the bike back: the tires' rolling resistance, the air's drag and, uphill, gravity; their sum times your speed is the power at the wheels, and the motors' and the pack's losses on top of it are what the cells pay. The arithmetic follows Martin and colleagues' (1998) equation, and the table below names a source for every input.

The model writes this provenance block each time it runs, and every row is taken from it: Ridstar's figures, the studies' figures, the comparables with their brackets, and physical constants. The references list every source again.

A ride worked through in full: a 180 lb rider on the 75 lb bike at 15 mph on flat pavement, motors alone. Rolling resistance takes 80.2 W and air drag 114.2 W, 194.4 W at the wheels, which the two motors share at 5.5 N·m each. They convert at about 74% and draw 262.5 W from the pack; the cells, after the pack's own losses, supply 271.0 W.

That is 18.07 Wh a mile, so 1,104 Wh lasts 61.1 miles, or 45.8 with a quarter kept back. On Martin and colleagues' own Appendix I inputs the model reproduces their 45.7 W of rolling and potential power and 158.8 W of aerodynamic power, and the comparable motor's efficiency at its rated point is 80%, the floor Bafang's workbook prints.

The motor curve is borrowed, so the model runs three motors, and the 15 mph flat figure stays between 61 and 70 miles across them. At 750 W each, the comparable gives 63 miles there and 14 on the 8% climb at 10 mph; at 82% efficiency, 70 and 16. Every table uses the 1,000 W case.

One owner's measured ride is the independent check, and the model comes out 20% longer. At "about 300lbs" on "a level paved former railbed", with pedal assist at 5, both motors on and full throttle, the owner rode 20 miles; the model's top steady speed for 300 lb is 28.5 mph, where its pack lasts 24.1 miles, 20.3% more.

That gap is printed, not tuned away. The owners' 33 to 35 mph wide open is faster than any steady speed the model holds, since it takes Ridstar's 31 mph as the motors' free-running speed, and riding faster costs miles.

Two looser reports come from the owner who gives a weight of 200 lb. "25 miles at fairly high speeds with no pedaling" sits near the model's 26.5 miles at 28 mph for that weight.

"41 miles" in pedal-assist level 1 at 13 mph, "pedaling the entire time" with "a little juice left", on a route with hills and two miles of rough off-road each trip, sits far under the model's flat 67 miles motor only and 111 with easy pedaling: if your routes look like that, read every table here as a ceiling.

Ridstar's "2000W(1000W*2)" goes into the model as two 1,000 W motors sharing the work evenly. Owners describe riding on the rear motor alone, which Ridstar does not describe, so Limitations carries it.

Two brake descriptions, LED lights and an LCD

Ridstar describes the brakes two ways: "Hydraulic dual brakes reduce braking distance by 50%" in both stores' bullets and "Dual Hydraulic Disc Brakes" in ridstar.net's description, against "dual disc brakes" in ridstar.com's design notes and "Brake Style Disc" in ridstar.net's Technical Details. The images split the same way, "HYDRAULIC DUAL BRAKES" on ridstar.net's four-panel image and "DUAL DISC BRAKE" on ridstar.com's.

Image 5 of ridstar.net's E26Pro gallery, image 7 of ours.

The third image on ridstar.com's E26 Pro listing. Its "21-SPEED" sits over a shifter printed "SHIMANO 7SPEED", and both stores' text says seven speeds.

Ridstar names no rotor size or brake maker and gives no test behind its 50%. One owner names the calipers twice: the bike "came with DY Island hydraulic brakes", by the October 2024 post, and the same owner's May 2025 post reads "I love the brakes DYIsland Hyd disc brakes and they work great!" Check the brake type on yours the day it arrives.

The same October post lists "headlight, turn, tail, and brake lights along with a horn and cell phone holder with a charging port", and names one gripe, "no regenerative braking", which the owner wanted for the local hills. Ridstar's copy promises a "Super Bright Headlight and Brake Light", "waterproof headlights and brake lights" and "IP5 waterproof protection".

Image 4 of ridstar.net's E26Pro gallery, image 6 of ours.

Two owners report light trouble. A review on ridstar.net's listing reads "the headlight and tail light wont turn on although the brake and turn signals do", and a Reddit owner wrote "my rear light broke off".

The display is an "LCD Colorful Display" tracking "your speed, mileage, battery level, PAS" in ridstar.net's description, and both four-panel images show it reading 15.9 km/h; neither store's text tells you whether it shows miles per hour. One owner calls it "the M5 display", and Ridstar's parts store sells an E26Pro display at $69.00.

An aluminum frame on a fork and a rear shock

The E26 Pro is sprung at both ends: a "100% reinforced front suspension fork" and a "rear hydraulic shock absorber" in both stores' bullets, which ridstar.com's copy calls "a 700Lbs shock absorber and dual front fork shock absorber system". ridstar.net's Technical Details give "Suspension Type Dual" and "Frame Material Aluminum", and neither store gives you the travel at either end.

Image 3 of ridstar.net's E26Pro gallery, image 5 of ours; the glowing springs are drawn into Ridstar's file.

Owners describe the suspension in plainer terms. One called the rear unit "the "shock absorber", which is just a spring", after "the tire has started rubbing the controller housing when the suspension compressed under normal pedaling", and a reviewer on ridstar.com wrote that "The front shops bottom out pretty often" (sic).

ridstar.net's fork listing sells an "E26PRO" front fork at $189.00. ridstar.net's Technical Details list "E-BIKE, Charger, Tool kits, User manual, LCD Smart Display, Headlight, Taillight, Rear Seat" as included, and Ridstar's text says its bikes "come 90% pre-assembled".

The Mercer fit test

The Mercers are our seven-person stand-in for the people who read these pages; below, each one lines up beside the E26 Pro, the adults by height and the children by age.

Each adult row sets a height against Ridstar's two windows, "5'7" -6'7"" on ridstar.com's slider and "5.3-6.3FT" on its fit image, then gives the 109% saddle height for a typical body that tall and the two counts the fit section explains. The figures belong to ANSUR II bodies of each height, so every row is an archetype.

Ages and heights are the ones we give each character, and their page introduces the family. The saddle heights and counts come from the fit model, run on ANSUR II bodies at each height and checked against the 33.8 and 38.5 inches on Ridstar's fit image.

Frank, Jack and Dana stand inside both of Ridstar's windows, and the taller the rider, the less room the 38.5 in top setting leaves: at Jack's 6'1" most riders need more than it gives. Ruth and Maya are under the slider's 5'7" and inside the image's window, so for them the two Ridstar figures disagree.

For the three shorter adults, Eunorau prints a window of "5'3" ~ 6'1"" for its two-motor FAT-AWD 2.0, a bike we sell in stock; our FAT-AWD 2.0 review sets its saddle against the same survey.

Cole, 16, and Ivy, 12, are ruled out by the listing itself: "Notice: E-Bikes Are Not for Sale to Persons Under the Age of 18. Underage riders MUST be accompanied by parents or adults when riding." A parent wrote on Reddit in July 2025: "So I mistakenly bought my son a Ridstar E26 Pro before I knew he had to be 16 to ride a Class 3 bike."

By Ridstar's own 2000W the E26 Pro is no class of e-bike at all, so a class's age line is not the rule that governs it; the class section shows which rules do. If you are buying for someone under 18, the bikes we sell are grouped by the rider's age in our kids and teens guide, with the age rules of every state alongside.

Is the Ridstar E26 Pro UL certified?

Ridstar's one UL claim for the E26 Pro concerns the battery alone, "UL certified 48V 23Ah removable battery" in both stores' bullets, and no standard, certificate holder or file number stands beside it. Before you pay any seller, get all three in writing.

An earlier image went further. In five Wayback Machine captures of ridstar.net's E26Pro listing, from November 3, 2024 to October 24, 2025, a third image showed the battery with a "UL LISTED" mark; the listing as served on October 25, 2026 no longer carries that image, and no Ridstar page names the certificate behind the mark.

UL Solutions calls UL 2849 "the Standard for Electrical Systems for eBikes". That certification, in UL's own description, is earned "by examining the electrical drive train, battery, and charger system combinations in e-bikes", the three parts together. A battery claim alone tells you nothing about the drive train or the charger, and the charger is the part the UK report found at fault.

Hold our shelf to the same request: for any bike you buy from us, ask us in writing which standard, holder and file number stand behind a safety claim.

In ridstar.net's footer, "Our Qualifications" offers three PDF links: "US trademark", "CE trademark" and "European trademark". Ridstar's name is registered as US Reg. No. 6,936,242, dated December 27, 2022, and as EU 018609888, dated March 16, 2022, each time to "Huizhoushi Xingqishi Sports Goods Co., Ltd.".

The "CE trademark" link opens an EN 15194 test report, ATS240329142LR, issued April 2, 2024 for a "Cargo electric bicycle", model "FM-002, CDDA20", with a "Maximum power measurement" of "250W". None of the three files names the E26 Pro, and none comes from UL; UL Solutions adds that "EN 15194 does not cover the safety of electrical systems utilizing battery packs in the same manner that UL 2849 covers this subject."

Has the Ridstar E26 Pro been recalled?

Not in the US. On October 25, 2026 the CPSC's recall list carried nothing from Ridstar, and no recall, warning or feed item named the E26 Pro. Both of the Commission's Ridstar stop-use warnings are about Q20 models and nothing else, and Britain's border rejection of 2025, which does name the E26 Pro, is a product safety report and not a recall.

The recall list ran to 10,058 records with the newest dated October 22, 2026; the recall feed's 40 items ran September 24 to October 22; and the warning list held 379 rows, two of them Ridstar's. A search for "E26" alone turns up two lamp recalls, one for a lamp socket and one for a bulb, both the E26 base size, so search the whole name, "E26 Pro", when you check.

Run the bike's name through the CPSC list again on the day you order, whichever store you order from.

The maker's record

One regulator has named the E26 Pro: Britain's Office for Product Safety and Standards, whose 2025 report on its chargers ends with the import rejected at the border. The US record holds two CPSC stop-use warnings and two lawsuits, all about Q20 models, and the E26 Pro's parts listings sell Q20 options beside its own.

The UK report that names the E26 Pro

Report 2506-0011, published June 19, 2025, covers "Ridstar E-Bikes Q20-Plus, Q20-Mini, E26 Pro and Chargers", each "A lithium-ion battery-powered bike with wall plug charger", at risk level "Serious" for fire. Its finding, in full:

"The product presents a serious risk of fire as the charger has poor quality soldering, and the transformer does not meet the minimum requirements for creepage and clearance distances. The plug also does not meet the dimensional requirements of BS 1363 because the distance from the live pin to the outside edge is too small. If the product was left plugged in overnight, the charger and plug could overheat, causing a fire."

The report adds that "The products do not meet the requirements of the Supply of Machinery (Safety) Regulations 2008 or the Plugs & Sockets etc. (Safety) Regulations 1994", and its corrective measure reads "The import has been rejected at the border."

The plug finding rests on BS 1363 and the UK's Plugs & Sockets etc. (Safety) Regulations 1994, so it concerns a charger made for British sockets; the report does not say whether chargers sold with US bikes share the soldering and transformer it describes. One E26 Pro owner, linking the report on Endless-Sphere, wrote "My charger has never once even gotten warm much less hot!"

Two CPSC warnings, both for Q20 models

The two releases as cpsc.gov served them on October 25, 2026; the E26 Pro appears in neither.

The March release names the maker, Huizhou Xingqishi Sporting Goods Co., Ltd., of China, says it "has refused to agree to an acceptable recall", and carries its reply: "The company objects to this press release." The June release names the same company, reports that it has "been unresponsive to CPSC's requests for information about these products or a recall", and urges owners "to stop using the e-bikes immediately and dispose of them".

Where the warnings reach the E26 Pro is the parts catalog. All eleven ridstar.net part listings with an E26 Pro option on October 25, 2026 sell Q20-family options too, among them the front axle "（Through shaft）" at $35.00, the front wheel nut kit at $25.00 and the front fork at $189.00.

Whether any E26 Pro part is the same part as a warned Q20's, no Ridstar page says. So ask your seller to state in writing which front axle and fastening hardware your bike carries, and follow the note at the top of ridstar.net's E26Pro listing: "Front tires must be securely installed".

Both warnings list Amazon.com, Ridstar.net and Walmart.com as sellers of the warned bikes, and the June release adds AliExpress; redtailebikes.com is not among them. The model number on your purchase receipt is how both releases say to check a bike against them.

Two lawsuits, both about a front wheel

Each suit alleges that a Ridstar lost its front wheel in use, and in each the defendant is the store that sold the bike, not Ridstar. Cunanan v. Amazon.com Services LLC concerns a "Ridstar Q20". Filed in federal court in Oregon as No. 3:26-cv-00692, it has a stipulated protective order of July 8, 2026 as its docket's newest entry, number 19.

L.E. v. Walmart Inc., No. 9:26-cv-81045 in the Southern District of Florida, was filed on a minor's behalf. Its complaint names the bike only by the title of a Walmart listing: "Ridstar Electric Bike, Peak 1500W30MPH,48V 15.6Ah Electric Bicycle, Full Suspension Mountain Bike UL2849".

Its newest entry, of October 23, 2026, is an "Order on Motion to Dismiss", and the free docket offers its text only for purchase on PACER.

Neither suit names the E26 Pro, whose 2000W and 23Ah match neither bike, and what the complaints say remains allegation.

What E26 Pro owners wrote

The fullest owner record is one Endless-Sphere thread on the E26 Pro: 115 posts from 13 authors between October 2024 and July 2026. It is owners writing to owners, so you are reading each one's own account; the three reviews on each Ridstar store add more.

The praise is specific: "The bike performs flawlessly so far and without the front motor would be in a world of hurt with the hills and mud around here", from the thread's opening post; "Right now I got about 1,300 miles on my Ridstar E26 pro", from a ridstar.com review.

So are the problems. One owner reported in January 2025 that "Ridstar sent me a new display and motor controller, but still no fix"; the same owner wrote in September 2025 that "They are fairly responsive, overnight response". Another, the same month: "My display has been acting up all year", with "Only one month left under warranty".

Who would you be buying from?

ridstar.net's company page gives a Hong Kong address in Hung Hom for "HK RIDSTAR TRADE LIMITED". The E26 Pro text on both stores, though, has Ridstar "Established in New Jersey and proudly serving the US since 2008". Ridstar prints both, and neither page tells you how the two fit together.

The paperwork adds two more names: the trademark certificates belong to "Huizhoushi Xingqishi Sports Goods Co., Ltd.", and the EN 15194 report lists "Huizhou Xingqishi Sporting Goods Co.,Ltd." as applicant and manufacturer, the name the CPSC gives for the maker of the warned Q20s. Our Ridstar profile sets out how Ridstar and its sister brand YVY connect.

Which Ridstar store would you be buying from?

Each of Ridstar's two stores claims the warranty for itself. On ridstar.net, Ridstar's official statement classes other sellers as dealers: "Except ridstar.net, other similar websites are our dealers". A buyer from any of those dealers is on their own after the sale, since Ridstar writes "we will not provide any after-sales service to customers who purchase ridstar products from other places".

On ridstar.com's E26 Pro page the line is "The Ridstar Warranty Policy is only available to customers ordering from ridstar.com".

On October 25, 2026, ridstar.net showed the E26 Pro sold out at $719.00 and ridstar.com in stock at $1,489.00. Two other sites offered it in stock at $510.00, ridstaearshop.it.com and ridssttaar.it.com, and a third, ridstar-ebike.com, listed "Ridstar E Bike E26 1500W E26 Pro 2000W Motor 48V 15AH/23AH Battery" at $999.00; Ridstar's European dealer, ridstar.eu, showed its E26PRO out of stock.

Before you pay any of them, get in writing who honors the warranty and who handles after-sales service, and hold the answer up against those two statements. The warranty itself differs by store: "a 1-year warranty on the motor, battery, and charger" in ridstar.net's text, and "a 2-year warranty" in ridstar.com's.

Where the E26 Pro sits among Ridstar's bikes

Of the nineteen Ridstar bikes reviewed here, the E26 Pro is the only one with two motors on 26-inch wheels: the H26 Pro, MN26 and DC26 drive one wheel on 26 × 4.0 tires, and the two-motor Q20 Pro and Q30 Pro ride on 20 × 4.0. The identity section sets out the E26 trims that share its name.

Eighteen more Ridstar reviews are live here for you to compare, each worked from Ridstar's published figures:

2000W at 28 to 31 mph: outside all 49 e-bike definitions

The federal "low-speed electric bicycle" of 15 U.S.C. § 2085(b) comes down to pedals and two numbers: "fully operable pedals and an electric motor of less than 750 watts (1 h.p.)". With a 170-pound rider aboard and the motor alone driving it, its top speed "is less than 20 mph". The E26 Pro has the pedals and misses both numbers on Ridstar's own figures.

Ridstar's 2000W is 1,250 W over the federal motor line, and both printed speeds, 28 and 31 mph, exceed the speed line by at least 8 mph.

Both statutes read October 25, 2026, the federal one on govinfo and California's on the Legislature's site, set beside Ridstar's two E26 Pro listings.

Every e-bike class in California's § 312.5(a) needs a motor that "does not exceed 750 watts of power", and the 2000W fails that before speed comes into it. The state's moped definition is the next one to read, and here Ridstar's two printed speeds give two answers.

§ 406(a) reads in full: "A "motorized bicycle" or "moped" is a two-wheeled or three-wheeled device having fully operative pedals for propulsion by human power, or having no pedals if powered solely by electrical energy, and an automatic transmission and a motor that produces less than 4 gross brake horsepower and is capable of propelling the device at a maximum speed of not more than 30 miles per hour on level ground."

§ 406(a)'s power limb is met: 2,000 W is about 2.7 horsepower. At Ridstar's 28 mph, so is the speed limb, and the range model's 28.6 mph for a 180 lb rider agrees; at the 31 mph in ridstar.com's copy and on both stores' motor image, it is not, and neither are the 33 to 35 mph owners report.

Neither § 406(a) nor any Ridstar page says whether the E26 Pro's hub motors count as "an automatic transmission". So the E26 Pro may be a California moped or no defined vehicle at all, and the answer turns on which speed your bike actually runs; ask the California DMV in writing before your first ride on a public road, and read our California page for the code around both sections.

State by state

An e-bike definition exists in 49 of the 51 jurisdictions, the 50 states plus DC. In 44 the motor limit is a wattage, Rhode Island states its limit in horsepower, and four definitions, the District's, Montana's, New Jersey's and Oregon's, carry no power figure at all. Alaska and Kentucky write no definition.

At 2000W and either 28 or 31 mph, the E26 Pro fits none of the 49. Even at 750 W, a 31 mph top speed would leave it outside all 49: the speed by itself rules it out.

Capped at 20 mph, a 2,000 W throttle bike would satisfy three definitions, the District's, Montana's and Oregon's; New Jersey's turns it away because it covers assistance only while you pedal. Neither Ridstar store gives you a 20 mph setting, and ridstar.net's E26Pro listing carries the line "Non-professionals please do not adjust the controller circuit！！！".

The 750 W line catches bikes beyond this one. Held to 20 mph, a 750 W throttle bike fits 29 of the 49 definitions: 19 states word the line as "less than" or "fewer than" 750 watts, which a motor of exactly 750 W does not meet.

The twentieth definition it misses is New Jersey's, which names no watt figure and covers assistance only while the rider pedals. For the wording itself, our atlas of state e-bike laws prints each definition as its statute has it.

Mud, sand and mountain trails: who decides where it rides

Ridstar sells the E26 Pro as "a mountain electric bicycle designed for mountain riding", on tires for "grass, dirt, sand, snow, and gravel" and "Perfect for off-road adventures in rugged terrains"; on each of those grounds, the agency that manages it decides whether a 2000W bike may go there. On a trail that admits e-bikes by class, your bike has no class to be admitted under.

Read as a California moped, the E26 Pro would fall under § 21207.5(a), which keeps a motorized bicycle off "a bicycle path or trail, bikeway, bicycle lane", equestrian trails and "hiking or recreational trail" unless the path is "within or adjacent to a roadway" or the agency in charge allows it "by ordinance".

The quoted words are Ridstar's, from its two E26 Pro listings. An agency's own posted rule takes precedence over this table; hold any watt or speed figure it gives up against Ridstar's 2000W and 28 to 31 mph.

National Forest rules treat the E26 Pro as a motor vehicle: the definition in 36 CFR 261.2 covers "any vehicle which is self-propelled", with exceptions only for rail vehicles and for devices built for people with impaired mobility.

After a Ranger District designates its motor vehicle routes and shows them on a motor vehicle use map, 36 CFR 261.13 declares it "prohibited to possess or operate a motor vehicle" on the District's National Forest land "other than in accordance with those designations".

Break any rule in Part 261 and the sentence under 36 CFR 261.1b can be "imprisonment of not more than six months", a fine at the level 18 U.S.C. 3571 sets, or both. Our public-land guide takes each federal land manager in turn before you load the bike for a trip.

Green flags / Red flags

What the E26 Pro does well, and what to settle before you buy one: eight of each, with every red flag closed by a step you can take today.

Green flags

• A motor in each wheel. Ridstar prints "2000W(1000W*2)", and at 10 mph up a 15% grade the model asks 71.3 of the pair's 90 N·m; one owner credits the front motor on "the hills and mud around here".
• 1,104 Wh in one removable pack. A 180 lb rider gets 61 miles at 15 mph on the motors alone on flat pavement, and you can lift the pack out to charge it indoors.
• Sprung at both ends. A "100% reinforced front suspension fork" and a "rear hydraulic shock absorber" in the bullets, and "Suspension Type Dual" in the Technical Details.
• Hydraulic calipers, by an owner's account. One owner names DY Island hydraulic brakes in two posts, and both stores' bullets print "Hydraulic dual brakes".
• A 330 lb load. At that total, the load rows still give 51 miles at 15 mph on the flat.
• Lights, a horn and a phone holder. An owner lists "headlight, turn, tail, and brake lights along with a horn and cell phone holder with a charging port", and Ridstar's feature list adds a "USB Charging Port".
• Parts the maker sells by name. On October 25, 2026, ridstar.net offered eleven parts with an E26 Pro option, from a $25.00 wheel nut kit to the $379.00 rear hub with its motor, every one available.
• We ship it free and file any damage claim. When it returns to stock here, delivery to you within the contiguous United States costs nothing; send photos within 48 hours of delivery and we handle the carrier and the repair or replacement.

• At 2000W it fits no state's e-bike definition. Read your state's wording in our atlas and learn what vehicle class a 2000W bike falls into where you live before it meets a public road.
• A UK safety report names its charger. Ask in writing which charger ships with the bike, and never leave it plugged in overnight, the case the report describes.
• Two brake descriptions, hydraulic and plain disc. Look at the calipers the day it arrives, and get the brake type in writing from any seller first; the brakes section quotes both descriptions.
• Every E26 Pro part listing also sells Q20 options, front axle and fork included. Ask whoever sells it to put the front axle and its hardware in writing, and check the front wheel's mounting before every ride; the maker's record lists the shared listings.
• The top saddle setting is short for most riders from 6'1". Measure your inseam: over 35.3 inches, plan on a taller saddle or a longer post, the change one owner made, and use the fit tables below that.
• Two stores, two warranties, each claiming the other's buyers get none. Decide whose warranty you are buying before you pay; Buying it from us sets Ridstar's two stores beside us.
• Two weights: Ridstar's 75 lb and an owner's "just under 100lbs". Plan racks, stairs and lifting on the heavier figure; the weight rows give the range cost of both.

Buy it if / Buy something else if

Buy it if the E26 Pro comes back into stock and a two-motor fat-tire mountain bike with suspension at both ends, a 1,104 Wh pack and room for 330 lb is the bike you want; your inseam sits under 35.3 inches, or you will fit a taller saddle; and you accept the vehicle class your state gives a 2000W bike.

At the August 2026 US residential rate, 18.16 cents a kWh, a full charge costs about 20 cents, and 1,000 miles at 15 mph on the motors alone about $3.28.

Buy something else if you cannot wait. The Freesky Eurostar Turbo M-410 is $1,299 here, in stock in four colors, and Freesky's record prints "2 × 2000W Peak Motors, Torque 105N·M *2", a "48V 25Ah Battery", "Front and Rear Suspension" and a "4-piston Hydraulic Brake".

At its printed "34 MPH by Pedal Assist or Throttle" it, too, sits outside every state's e-bike definition, which makes it a fit for the same rider as the E26 Pro.

Buy something else if you want a bike with a 20 mph top speed. The Eunorau FAT-AWD 2.0, $1,699 in Raven or $1,799 in Maple, keeps two motors and prints "Maximum Speed: 20MPH", "Total Payload Capacity: 375 lbs" and a rider window of "5'3" ~ 6'1""; check its "Front 48V/500W+Rear 500W" against your state's wording in our atlas.

Buy something else if you ride rough ground on one motor. The Samebike STORM, $1,299 here, lists a "Rear Shock", a "Dual-shock front fork", "Hydraulic disc brakes" and a "Shimano 8 Speed" on a "1000W motor can peak to 1800W".

Before you buy: the checklist

Whoever sells you an E26 Pro, us once it is back or anyone else, these six checks come before the order and again before the bike's first public-road ride.

1. The class. Look up what your state calls a 2000W bike in our atlas, and have whatever that class demands in place before the first ride.
2. The saddle. Measure your inseam barefoot; over 35.3 inches, the fit section shows the top setting falls short, so budget for a taller saddle or a longer post.
3. The load. Step on a scale in your riding clothes, holding everything you bring along; past 330 lb you are over Ridstar's limit, and the load rows show the miles for each total.
4. The front end. The maker's record explains the shared parts listings; ask for the front axle and its hardware by name, in writing, and look over how the front wheel is mounted before each ride.
5. The charger. Ask the seller in writing which charger ships with the bike, and never leave it plugged in overnight.
6. The first day. Open the box the day it arrives, because our shipping policy asks for damage reports within 48 hours; Ridstar ships its bikes "90% pre-assembled", so check each bolt you tighten yourself, then use the heel check to set the saddle.

Buying it from us

Our E26 Pro listing was sold out at $826.85 on October 25, 2026; the terms below are what you get when it returns, and what you get today with the M-410, the STORM and the FAT-AWD 2.0. Each row quotes the page that says it.

Every term comes from its own page, read October 25, 2026: shipping policy, refund policy, terms of service, contact page and our checkout. That day our checkout quoted $0.00 shipping on the M-410 to California, Florida, Illinois, New York and Texas, and to Alaska and Hawaii; the policy asks buyers in those last two to write first.

Changing your mind is possible, but only briefly. Our refund policy requires a return to be "unopened and in factory-sealed original packaging" and "within 72 hours (3 days) of delivery". Even then you lose "a 15% restocking fee plus return shipping", and canceling an order costs "a 3% transaction fee".

ridstar.com sold the E26 Pro in stock on October 25, 2026, and ridstar.net showed it sold out; the table sets both stores beside us.

Sources, all October 25, 2026: ridstar.com's E26 Pro page, which prints its "15-Day Money-Back Guarantee", return and warranty wording, and the "Ridstar/YVY User Manual" page its support menu links, which prints the cancellation fee; ridstar.net's return policy, its official statement and the E26Pro listing; our own policies for the first column.

Get repairs settled in writing before you pay. ridstar.net's warranty page has "Ridstar dealers or Ridstar authorized partners" repairing defects "at no charge", while each store's own words withhold support from the other's buyers.

Should a bike bought here arrive defective, the manufacturer's warranty covers it under our refund policy, and the repair or replacement is ours to coordinate, so a Ridstar from us carries Ridstar's terms and ours together.

Frequently asked questions

How much does the Ridstar E26 Pro cost?

On October 25, 2026, ridstar.com sold the E26 Pro in stock at $1,489.00 against a "Regular price" of $1,789.00, and ridstar.net showed it sold out at $719.00. Our listing was sold out at $826.85. Two .it.com sites offered it at $510.00 and ridstar-ebike.com at $999.00; the maker's record explains why you should get the warranty in writing before you pay any of them.

How fast does the Ridstar E26 Pro go?

ridstar.com prints "a top speed of 28+++ mph", "Max Speed 28 MPH" and "a maximum speed of 31mph". The range model, reading 31 mph as the motors' free-running speed, holds a 180 lb rider at 28.6 mph on the flat; owners report 30.7, 34.1 and "33-35mph wide open on level ground". Whichever of those speeds you take, the class section shows the bike landing outside every state's e-bike definition.

How far can the Ridstar E26 Pro go on one charge?

With no pedaling on flat pavement, a 180 lb rider computes to 82 miles at 10 mph, 61 at 15 and 27 at 28; plan on three quarters of each. Ridstar's own figures run from 25 to 87 miles with no speed attached. Hills cut the distance hard, to 15 miles on an 8% grade at 10 mph, and the range tables give your speed, load and temperature.

How long does the Ridstar E26 Pro's battery take to charge?

Ridstar prints "4-6 HOUR" over "Charge Time" on ridstar.com's second image, and no charger output. Filling 23 Ah in that time would take a charger of about 3.8 to 5.75 A, so ask the seller for the charger's rated output before you rely on the figure, and don't leave it plugged in overnight.

Can you buy a spare battery for the Ridstar E26 Pro?

Yes, at $499.00 on October 25, 2026: ridstar.net's battery listing, titled for the Q20, DC26 and H20, sells a "US / E26Pro" option, and YVY's twin listing sells "US / E26 Pro" at the same price. Neither names the capacity for that option, so confirm in writing that it is 48V 23Ah before you pay.

How heavy is the Ridstar E26 Pro?

Ridstar prints "75LBS" over "Product Weight" on ridstar.com's fit image, and neither store's text gives a weight. When a shopper on Endless-Sphere asked "What's the weight of the bike? I could not find it anywhere online.", an owner answered: "It does not fold. It weighs just under 100lbs." The weight rows show you the range at both.

Does the Ridstar E26 Pro fold?

No, by one owner's account. ridstar.net's address for the listing says "folding", but its title, "Ridstar® E Bike E26Pro Fat Tire Mountain Electric Bike", does not, and when a forum member asked "Is it really foldable, where?", an owner answered: "That's the bike I have. It does not fold."

Does the Ridstar E26 Pro have hydraulic brakes?

Ridstar says so and says otherwise. Both stores' bullets print "Hydraulic dual brakes" and ridstar.net's description "Dual Hydraulic Disc Brakes", while ridstar.com's design notes say "dual disc brakes" and ridstar.net's Technical Details "Brake Style Disc". One owner names DY Island hydraulic brakes on their bike; check the calipers on yours.

Can you ride the Ridstar E26 Pro on one motor?

Owners say yes, though Ridstar does not describe it. One writes on Endless-Sphere "I mostly ride on just the rear motor just kicking the front on as needed", and a ridstar.com reviewer that the second motor "doesn't make you go any faster you just reach the top speed faster". The range model splits the work evenly between the two, so if you ride on one, the tables do not cover you.

Does the Ridstar E26 Pro need a key?

Ridstar sells the E26 Pro's throttle as a part with "two keys included", $59.00 on ridstar.net, and its return policy counts "keys" among the items a return must include. It does not say what the key turns on or locks, so ask the seller before you buy if it matters to how you park.

Is the Ridstar E26 Pro street legal?

At Ridstar's 2000W it matches none of the 49 e-bike definitions that the states and DC have written (Alaska and Kentucky wrote none), so where it may ride depends on the vehicle class your state gives it. In California it may be a moped under § 406(a) at 28 mph and no defined vehicle at 31; the class section quotes the text.

Can a teenager ride the Ridstar E26 Pro?

No. Ridstar does not sell the bike to anyone under 18, and its own listing says so: "Notice: E-Bikes Are Not for Sale to Persons Under the Age of 18. Underage riders MUST be accompanied by parents or adults when riding." A parent on Reddit bought one for a son before learning the class rules, and at 2000W the bike is no class of e-bike at all; our kids and teens guide matches bikes to ages.

Is the Ridstar E26 Pro safe?

No US recall or CPSC warning names it. Britain's OPSS rejected an import of Ridstar chargers, the E26 Pro's among them, finding "a serious risk of fire", and the CPSC's two Ridstar warnings name Q20 models. Ridstar's one UL claim covers the battery and names no certificate. Ask for the charger's paperwork, never leave yours plugged in overnight, and read the maker's record.

Does the Ridstar E26 Pro fit tall riders?

Ridstar's slider says "5'7" -6'7"", but its fit image puts the top saddle setting at 38.5 inches off the ground, short of the 109%-of-inseam height for at least 58 of 100 riders at 6'1" and 97 at 6'4" in the Army's ANSUR II survey. One owner at about 6'2" fitted a saddle two inches taller; the fit section has your row.

Where can I get a replacement display for the Ridstar E26 Pro?

From Ridstar: on October 25, 2026, ridstar.net's LCD listing sold an "E26Pro" display at $69.00, available, beside its $89.00 E26 Pro controller. An owner whose display failed wrote that Ridstar support "sent me a new one" and a controller, with "overnight response", so contact support first if yours is under warranty.

Is there a manual for the Ridstar E26 Pro?

A paper one ships in the box: ridstar.net's Technical Details list a "User manual" among the included components. Online, ridstar.com's support menu links a "Ridstar/YVY User Manual" page, but on October 25, 2026 that page carried the store's return terms and linked no manual file, so ask Ridstar's support for a PDF before you buy if you want one.

Can you make the Ridstar E26 Pro faster?

Ridstar's E26Pro listing carries the line "Non-professionals please do not adjust the controller circuit！！！", and at its printed 28 to 31 mph no state's e-bike definition covers the bike already, and more speed only widens that gap. If you need more speed than the E26 Pro offers, Freesky prints the M-410 at "34 MPH by Pedal Assist or Throttle".

Is the Ridstar E26 Pro worth it?

If it comes back into stock and you want two motors, suspension at both ends and 1,104 Wh on 26 × 4.0 tires, its 61 miles at 15 mph and $826.85 price make a strong case, provided you clear its saddle range, its class and its charger question. If you need a bike now, the M-410 does the same job in stock.

Limitations of this review

Each item below marks where the published record stops, what this review assumed in its place, and what that gap means for your purchase or your ride.

1. Where Ridstar's own figures disagree, every version is printed. Top speed: "28+++ mph", "28 MPH" and "31mph". Range: six statements from 25 to 87 miles. Rider window: "5'7" -6'7"" and "5.3-6.3FT". Brakes: hydraulic and plain disc. Gears: "7-speed" and "21-SPEED". Warranty: one year on ridstar.net, two on ridstar.com.
2. No continuous motor rating, no motor maker, no controller figure. Bafang's RM G0H0 curve, scaled to 1,000 W for each motor from "2000W(1000W*2)", stands in for the motor; the sensitivity rows move the 15 mph figure between 61 and 70 miles.
3. The motors are modeled sharing the load evenly. Ridstar does not publish how its controllers split the work, and owners describe riding on the rear motor alone, which no table here covers.
4. The model cannot reach the owners' top speeds. It takes Ridstar's 31 mph as the motors' free-running speed, while owners report 33 to 35 mph, and at its fastest speed the model's figure runs 20.3% over the one measured ride; another report, 41 miles on hilly, partly off-road ground, sits far under the flat tables.
5. The fit image's arrows do not match its labels. At the scale of the 46-inch bar arrow, the saddle arrows run 13.2% and 15.6% long, so the page uses the printed 33.8 and 38.5 inches and measures nothing on the drawing.
6. The pedal's height is unpublished. With no bracket height or crank length, the fit counts are floors at the top setting's ceiling and certainties at the bottom, and every rider between them depends on a figure Ridstar does not print.
7. "5.3-6.3FT" can be read two ways. As decimal feet it is 63.6 to 75.6 inches; as feet and inches, 5'3" to 6'3". The page prints both.
8. ANSUR II measured soldiers. Soldiers are not a sample of the public at large, and above 6'4" the 4,082 men and 1,986 women thin out too far to fill a row.
9. No cockpit or grip figures. Without a grip reach, stem length or seat-tube angle from Ridstar, the page computes no lean and no hand load, and its one hand figure comes from road racers on another kind of bike.
10. No knee is measured. The page gives the cycling literature's 25 to 35 degree knee range as Peveler, Pounders and Bishop report it and measures no rider's knee, so the heel check on your own bike settles the height.
11. The cold rows rest on one cell's data. Ridstar names no cell, so the energy column uses LG's HG2.
12. The charger's output and the US charger's design are unpublished. The UK report describes chargers rejected at its border; whether chargers sold with US bikes are the same is not on the record.
13. The bike's weight has two sources. Ridstar's fit image prints 75 lb, an owner reports "just under 100lbs", and the model runs both.
14. Two regulators could not be read. Australia's ACCC refused the request and the EU's Safety Gate search would not answer on October 25, 2026, so this page says nothing about either.
15. The owner record is small. One forum thread of 115 posts from 13 authors, six store reviews and eight Reddit posts name the bike.
16. Five photographs on our own listing are not the E26 Pro's evidence. Two are Ridstar's photographs of its 1000W E26, and three match no Ridstar listing; nothing on this page rests on them.
17. The Florida order's text is behind PACER. The free docket shows the October 23 "Order on Motion to Dismiss" by title only.
18. California's moped test has an open limb. No source read says whether the E26 Pro's hub motors count as "an automatic transmission" under § 406(a).
19. No UL file number to look up. Neither Ridstar store, nor the "UL LISTED" battery image its listing carried until at least October 2025, names a certificate holder or file number, so UL's own directory had nothing to be searched for.

The bottom line

When it is back in stock, the E26 Pro earns your look if you want two motors, suspension at both ends and 1,104 Wh on 26 × 4.0 tires for $826.85, have an inseam under 35.3 inches or a taller saddle in mind, and accept riding under whatever class your state gives a 2000W bike.

Its pack computes to 61 miles at 15 mph on flat pavement for a 180 lb rider on the motors alone. Wherever you order one, read the maker's record first, ask which charger comes in the box, and have the front axle named in writing.

It was sold out here on October 25, 2026. Of the bikes you can order today, the Freesky Eurostar Turbo M-410 comes closest: two motors and a 25Ah pack at $1,299; for a 20 mph top speed with two motors, the Eunorau FAT-AWD 2.0 starts at $1,699.

Image credit: below the cover, every image is one of Ridstar's own pictures from its ridstar.net and ridstar.com E26 Pro listings, used whole and scaled evenly without retouching, except the battery panel, which crops ridstar.com's second image to its right half.

Cover: the bike is Ridstar's own studio photograph, the first image on its ridstar.net E26Pro listing, scaled evenly and otherwise untouched; the blue glow inside the wheels is in Ridstar's file.

The charcoal studio around it was generated with Nano Banana Pro on Playcut (playcut.ai) for an earlier cover and is reused as it was. Under the tires, the photograph's own floor shadow is carried onto the studio floor with a contact shade at each tire, and the type and the badge are ours.
