Folding 26-inch fat-tire e-bike · one motor Ridstar prints at 1,500 W for its US model and at 2,000 W, dual, for its EU one · 48V 20Ah pack, 960 Wh · 26 × 4.0 tires, front fork and rear shock, hydraulic discs · 330 lb load, rider windows of 5.5 to 6.2 ft and 5'7" to 6'7" · $803.85 on October 15, 2026 · verified October 15, 2026
Quick Answer — The Ridstar H26 Pro is a $803.85 folding fat-tire e-bike with a 48V 20Ah pack, 960 Wh by arithmetic, and a motor Ridstar prints at 1,500 W for the US and 2,000 W for the EU. With no pedaling at a steady 15 mph on level pavement, a 180 lb rider computes to 54 miles; Ridstar prints 44 miles.
Ridstar's pages give more than one answer to the motor, the pack, the top speed, the range, the weight and the rider window, and the specification table sets them side by side. Settle three things before you order: which motor and pack our listing ships (which H26 Pro), what your state calls a motor of this size (class), and the weight you will lift (weight and load).
Our store listed the H26 Pro at $803.85 on October 15, 2026, and ridstar.com's US variant showed in stock that day at $1,399.00. This button opens checkout, which took a credit card or Google Pay that day. We pay the freight to the contiguous United States and file the carrier claim ourselves if a box arrives damaged.
Buy the H26 Pro, $803.85The maker's record, before you buy. The Consumer Product Safety Commission issued two 2026 stop-use warnings for Ridstar e-bikes made by Huizhou Xingqishi Sporting Goods Co., Ltd. of China: 26-337, for the Q20 and Q20 Pro, over batteries and wires that can ignite, and 26-584, for the Q20 and Q20 Lite, over a front wheel that can detach. The H26 Pro is in neither, no Ridstar recall exists, and the record section quotes both.

How we verified this Ridstar H26 Pro review
Every H26 Pro figure here was read on October 15, 2026 from Ridstar's ridstar.com listing with the US market selected, its page text and its fourteen gallery images, one of them a dimension drawing enlarged for reading. Ridstar's earlier ridstar.net page for the same name was read from its September 4, 2026 capture and our August 26 deposit.
The warnings, the recall list, the dockets and our store's price, stock, shipping, checkout and refund terms were read the same day. Every figure is verified against Ridstar's published specification and recomputed where arithmetic is involved, and the range and fit sections name each input. We sell the H26 Pro, so the red flags get the same care as the green ones.

Ridstar's H26 Pro specification, figure by figure
Ridstar's ridstar.com page prints two top speeds, two weights, two rider windows, three ranges and a headline that says "Dual Motor" above a one-motor US variant, and the table sets each reading beside the text it comes from. The third column quotes the listing, and the fourth gives what other Ridstar pages print for the same name.

Read October 15, 2026 from Ridstar's ridstar.com listing and its gallery drawing, from ridstar.net's September 4 capture and from ridstar.eu's H26 PRO page.
On October 15, 2026 ridstar.com asked $1,399.00 in US dollars for its US variant, in stock, and $1,499.00 for the EU one, sold out. ridstar.net answered 404 for the H26 Pro, though the Wayback Machine holds the page live on September 4, 2026 at $699 with the line "Many in stock". Ours is $803.85, and the buying section sets out what that difference buys and what it does not.
The August page and the DC26's carried descriptions that match on 51 of their 52 lines, and the line that differs is the motor's. Where Ridstar's pages disagree with each other, this review prints both figures with their sources and does not say which is right; where a calculation has to run one figure it says which and shows the other, and the range section works out what each range figure asks of the rider.
Which H26 Pro is this? One name, three configurations
On our shelf the H26 Pro is Ridstar H26 Pro 2000W Folding Fat Tire Mountain Electric Bike, a name that follows the one ridstar.net gave its page, and Ridstar's pages describe three machines under the H26 Pro name. The motor and the pack are the two things that differ, and a buyer should know which pair arrives.
ridstar.net's page, live until at least September 4, 2026, called the bike "Ridstar H26PRO 2000W Folding Fat Tire Mountain Electric Bike" and gave it a PEAK 2000 W motor, a 48V 20Ah pack, "70 LBS", a 21-speed drivetrain and a 5'7" to 6'7" window for $699. The store has since removed it.
ridstar.com's US variant is "48V 1500W", a 48V 20Ah pack and seven speeds for $1,399.00, and its EU variant is "52V 2000W (Dual 1000W motors)". The dealer ridstar.eu lists an "H26 PRO" at 1,500 W and 23Ah for €1,199 and a separate "H26PLUS" at 2,000 W with dual motors for €1,499.
| Where | Name it carries | Motor | Pack | Price, October 15, 2026 |
|---|---|---|---|---|
| ridstar.com, US variant | H26 Pro | "48V 1500W" | 48V 20Ah | $1,399.00, in stock |
| ridstar.com, EU variant | H26 Pro | "52V 2000W (Dual 1000W motors)" | 52V 20Ah | $1,499.00, sold out |
| ridstar.net, September 4 capture | H26PRO | PEAK 2000 W | 48V 20Ah | $699, "Many in stock" (page removed) |
| ridstar.eu | H26 PRO | "1500W DC brushless" | 23Ah | €1,199 |
| ridstar.eu | H26PLUS | dual 1,000 W, front and rear | 52V 20Ah in its table, 48V in its title | €1,499 |
| Our listing | H26 Pro 2000W | 2000W in the title | 48V 20Ah | $803.85, buyable |
Ridstar's prices as each page printed them on October 15, 2026, in US dollars on ridstar.com with the US market selected and in euros on ridstar.eu. ridstar.eu calls itself an "Official e-shop", and ridstar.net's statement calls every other Ridstar-named site a dealer.
The 2,000 W in our listing's title is a peak figure on the page ridstar.net removed, and ridstar.com's US variant prints 1,500 W. The August H26PRO text says "PEAK 2000W", and the DC26's matching line says "1500W (PEAK 2000W)", so on that store the 2,000 W was a peak and the 1,500 W the headline rating. ridstar.com adds "Motors up to 1500W peak" to its US variant's text.
Ridstar publishes no continuous rating for any of them. An owner wrote on r/ebikes on September 30, 2025: "Motor is a typical hub motor with 1000W nominal power and 1500W peak power", one person's statement about their own bike.
Email us before you order and we will answer in writing which motor and which pack the unit on our listing carries. Put your state in the same email if the motor rating matters to where you ride, and you will have our answer before you pay.
Ask us which H26 ProThe DC26 is a different listing and this review does not cover it. ridstar.com prints it as a separate bike with its own figures today, and the two names carried near-identical descriptions on ridstar.net in the August record. Google suggests "ridstar h26 plus" as a search, and the only H26 Plus on the record is ridstar.eu's dual-motor listing above.
Our Q50 review sets out Ridstar's other big-pack bike, with the same figure-by-figure table. It is the nearest sibling on our shelf if the H26 Pro's hinge is not what you need.
Read the Q50 reviewOf the other Ridstar bikes we review, the warnings name three: the Q20 in both, the Q20 Pro in the fire warning and the Q20 Lite in the front-wheel warning. The two-motor Q30 Pro, the step-through MN26 and the Q30 Lite, listed on ridstar.com as the Q50 Lite, are named in neither, and all of them sit in our e-bike reviews index beside other makers' bikes.
Who the H26 Pro fits: Ridstar's two windows
By the standard saddle formula, 109% of inseam from the pedal axle, a median 5'10" rider in the US Army's ANSUR II survey needs the saddle top 36.8 inches above the pedal, and a median 6'2" rider 39.3 inches. Ridstar prints a rider window in two forms, and a window cannot say which bodies it suits: in the same survey, riders of one height differ by about three inches of inseam.
Ridstar's specification block prints "5.5- 6.2 Ft", which is 5'6" to 6'2.4" read as decimal feet. The carousel panel and the dimension drawing print "5'7" -6'7"" and "5'7"-6'7"ft", the window ridstar.net's September 4 capture printed too.
The tables below run from 5'0" to 6'4", the tallest height with 30 or more bodies in the survey, so they cover the first window and the second up to 6'4".

Ridstar's gallery drawing, as it prints it. The letters A to K carry no names, and the drawing's weight badge disagrees with the specification block's.
Get your own figure in three steps:
- Measure your inseam in stocking feet against a wall, with a book pressed up between your legs.
- Find your height in the saddle table and read the saddle top to the pedal axle that matches your inseam.
- Set the saddle with the heel check in the setup subsection, then bend the knee to the 25 to 35 degree target.
The listing prints two geometry figures, "120CM" for the handlebar height from the ground and "105CM" for the seat height from the ground, and says neither where the seat height is measured nor whether it is a highest or a lowest setting. Of the drawing's eleven lettered dimensions, only F, at 1,200 mm and 47.2 in, matches one of those two lines, the handlebar height; none is 1,050 mm, the seat height.
Ridstar prints no crank length, saddle range, standover or reach. The model therefore prints the formula and both windows, and it computes no lean, hand load or clearance for a frame whose dimensions are not defined.
Email us your height and your inseam, in inches, and this model's saddle figures for your body come back in writing. If you also want the seat height measured from the pedal axle on the bike you would receive, put it in the same email and you will have our written answer before you order.
Ask us to run your fitWhat seat height does the Ridstar H26 Pro need?
The saddle top goes at 109% of your inseam, measured from the pedal axle, the figure Peveler et al. (2005) compared with the heel method. Ferrer-Roca et al. (2012) give 106% to 109% as their recommended range and 108.6% to 110.4% from their equation, so the table prints 106% and 110.4% as its two ends.
The inseam bands are the middle 90% of the 6,068 bodies in the US Army's ANSUR II survey. Ridstar prints one seat height, "105CM", and no range, so the table shows where the formula puts your saddle and cannot say whether the seat post reaches it.
| Your height | Typical inseam | Saddle top to pedal axle | At 106% | At 110.4% |
|---|---|---|---|---|
| 5'0" | 27.1–29.7 in | 31.0 in | 30.2 in | 31.4 in |
| 5'2" | 28.0–31.1 in | 32.2 in | 31.3 in | 32.6 in |
| 5'4" | 29.1–32.2 in | 33.3 in | 32.3 in | 33.7 in |
| 5'6" | 30.2–33.5 in | 34.5 in | 33.6 in | 34.9 in |
| 5'8" | 31.1–34.3 in | 35.6 in | 34.6 in | 36.0 in |
| 5'10" | 32.2–35.5 in | 36.8 in | 35.8 in | 37.3 in |
| 6'0" | 33.2–36.7 in | 38.1 in | 37.0 in | 38.6 in |
| 6'2" | 34.3–37.5 in | 39.3 in | 38.2 in | 39.8 in |
| 6'4" | 36.3–39.1 in | 41.0 in | 39.9 in | 41.6 in |
The formula saddle table. Inseam bands are the middle 90% of ANSUR II bodies at each height, at least 30 per band. The 109% column is Peveler et al.'s figure, and the 106% and 110.4% columns are the ends of the Ferrer-Roca ranges. Ridstar publishes no crank length, so LeMond's 88.3% column is not computed.
A median 5'10" rider sets the saddle top 36.8 inches above the pedal axle and a median 6'2" rider 39.3 inches, and Ridstar's one seat height cannot say whether the post reaches either.
What is the Ridstar H26 Pro's standover height?
Ridstar prints no standover height for the H26 Pro, so the clearance over its frame cannot be computed. For scale, the median inseam in the Army survey is 33.8 inches at 5'10" and 36.0 inches at 6'2".
Measure the frame on the bike you receive before you count on both feet reaching the ground at a stop. The email offer above covers it before you order.
Will you sit stretched or cramped on the H26 Pro?
The lean is not computed, because Ridstar publishes no grip position or reach for the H26 Pro. The lean depends on both, and the photographs show the bike without a rider on it. Sit on one at rest if you can; otherwise the email offer above takes your arm length too.
Weight on your hands
Hand load depends on where the grips sit, and no grip position is published for the H26 Pro, so no hand load is computed. The one measured reference this page can cite is about 15% of body weight through the stem, from Carahalios (2015) on ten road racers with their hands on the hoods; it is a ceiling for a racer leaning forward, and no H26 Pro figure is computed from it.
What size is the Ridstar H26 Pro?
Ridstar's listing offers one frame on 26 × 4.0 tires for riders it puts between 5.5 and 6.2 ft or between 5'7" and 6'7", so the fitting happens at the seat post when the box opens.
Start with the heel check: sit with the heel on the pedal at the bottom of the stroke and the crank in line with the seat tube, and straighten the leg. If your hips rock on the saddle, or the leg cannot straighten, the saddle is too high.
Then pedal on the ball of the foot and aim for 25 to 35 degrees of knee bend at the bottom of the stroke, the target Peveler, Pounders and Bishop (2007) and Ferrer-Roca et al. (2012) bracket. Two riders of one height can need different settings, so treat the formula as the first guess.
The fit arithmetic, step by step
The model reads each body's inseam from ANSUR II and prints the saddle top at 109%, 106% and 110.4% of it, from the pedal axle. Worked through for a 68-inch rider: the model's inseam at that height is 32.6 inches, so the 109% saddle sits 35.6 inches above the pedal axle, the 106% saddle 34.6 inches and the 110.4% saddle 36.0 inches.
| Input | Value | Source |
|---|---|---|
| Bodies | 6,068 ANSUR II bodies | US Army ANSUR II survey |
| Inseam bands | at least 30 bodies per band | the same survey |
| Saddle formula | 109% of inseam, from the pedal axle | Peveler et al. (2005) |
| Saddle band | 106% and 110.4% of inseam | Ferrer-Roca et al. (2012) |
| Rider windows | 5.5 to 6.2 ft and 5'7" to 6'7" | Ridstar's ridstar.com listing |
| Crank, seat range, standover, reach | not published by Ridstar | Ridstar's H26 Pro listing |
At 109% the model gives the figure Peveler et al. (2005) report, 109.2 ± 0.9%. Ridstar prints no saddle range to check the output against, and Limitations lists that gap.
Folding: 3 seconds, 10 seconds or one button
Ridstar's page says "3-second folding" in its text and "Folds in 10 Sec" in its title, and it prints three folded sizes that do not match. The listing adds "one-button folding, convenient storage, easy to put into the trunk", and its specification block gives "Foldable: Yes" beside a "Foldable size" of "113/10/100cm" with no unit on the first two numbers and no label on any of the three.

| Where | Folded size as printed | In inches |
|---|---|---|
| ridstar.com spec block | "113/10/100cm" | 44.5 × 3.9 × 39.4 |
| ridstar.com drawing, letters I, J, K | 1000 × 1000 × 730 mm | 39.3 × 39.3 × 28.7, as Ridstar prints them |
| ridstar.net, September 4 capture | "393928.7" when folded | 39 × 39 × 28.7 |
| ridstar.com box | "(1603180CM)" | 63.0 × 12.2 × 31.5 |
Read October 15, 2026 from the ridstar.com listing and its gallery drawing, and from ridstar.net's capture. The inches in the first and last rows are our conversion.
The drawing's folded size and ridstar.net's agree, so a folded footprint of about 39 by 39 inches, 28.7 inches deep, is the figure two Ridstar pages share. The spec block's three numbers fit no folded bike as written, since a 3.9-inch middle figure would be a bike thinner than its tires.
An owner who rides it for deliveries wrote on r/ebikes on March 19, 2025 that "it is very easy to store in a garage or a small space in your house, it is not hard to fold, just take the battery out while half folded so it is easier." That is one person's account of one bike, and the page lists no battery-removal step for folding.

If you will fold it every day, email us the stairs, the trunk or the closet it has to fit; our answer arrives in writing before you order. The folded footprint, the weight and the fold steps are the three figures to ask for.
Ask us how it foldsA motor hub in the rear wheel, rated two ways
Ridstar's ridstar.com page rates the US variant's motor at 1,500 W in its specification block and calls it "up to 1500W peak" in its text, and it heads the description "1500W Dual Motor". The spec block gives "48V 1500W (US/CA/UK warehouses)" and, for the EU, "52V 2000W (Dual 1000W motors)(EU warehouse)", and it puts the motor's position "On the F&R wheel and rear luggger".

A Ridstar gallery photograph, scaled uniformly: the rear wheel carries the motor hub and its disc. The front wheel's hub carries a disc and no motor housing.
Ridstar's photographs show a motor hub at the rear wheel and a plain hub with a disc at the front, while its spec block places the motor "On the F&R wheel and rear luggger" and its headline says "Dual Motor". A December 5, 2025 post speaks of "the rear hub motor", and a September 30, 2025 post of "a typical hub motor" with a noise "coming from the rear wheel".
Ridstar's controller and charger lines frame the 1,500 W figure. The listing prints "sine wave controller", "Voltage: 48V" and "Current: 28A", and its charger line "54.6V/3A". At the full-pack 54.6 V that charger implies, 28 A is 1,529 W, and at a nominal 48 V it is 1,344 W; both are arithmetic on Ridstar's figures, and Ridstar prints no continuous rating.
Two speeds sit on Ridstar's pages. The spec block says "37 MPH", the carousel panel "28 MPH" and the text "a top speed of 28 mph", and ridstar.net's September 4 page printed "28+++ mph".
Our range model rebuilds a published hub-motor curve, Bafang's RM G0H0, at 48 V and 1,500 W with its no-load speed set from Ridstar's 37 mph, and for a 180 lb rider on level pavement it holds 31.9 mph at most.

A Ridstar gallery photograph, scaled uniformly: the right grip and its controls. The listing names three riding modes, "Pure Electric, Power Assist, Bike Mode", and no throttle.
Owners write about this drivetrain from daily use. A delivery rider's first post, at 500 km, says "the motor is powerful and you can feel the 1500W" and that "the pedal assist uses a motion sensor, not a torque sensor". That owner's September 30, 2025 post, at about 4,500 km, says "I changed the planetary gears 1500KM ago" and asks about a noise between 18 and 26 km/h.
A second owner wrote on December 5, 2025 that "I was riding it in the snow today and started hearing weird clanking noises coming from the rear hub motor. A few seconds later the motor stopped working." Each post is one person's account, none is counted with another, and this review read no reply to either.
Ridstar's own parts store sells the drive train for it. The controller listing carries a "US / H26 Pro" variant at $89, the motor listing a "US / H26 Pro" variant at $209 and the charger listing a "US / H26 PRO" variant at $69, each in stock on October 15, 2026.
Ridstar's two ratings decide how the law reads the bike. 44 of the 51 state definitions in our census set a 750-watt motor limb, and the H26 Pro sits above it at 1,500 W and at 2,000 W. The range tables carry the 2,000 W reading as a sensitivity row.
Your state's definition decides what a 1,500 W motor is on its roads, and our atlas sets out each one from its statute.
Check your state's lawOne 48V 20Ah pack: 960 Wh
Ridstar's listing prints one removable 48V 20Ah pack for the US variant, which is 960 Wh computed from 48V and 20Ah as published. At our price that is 84 cents per watt-hour of pack, against 139 cents for the Samebike LO26 Plus's 720 Wh and 193 cents for the VTUVIA SF20H's 672 Wh.
The pack size is not settled on Ridstar's own pages. The title and the variant name say 20Ah, the product's handle reads "23ah", the dealer ridstar.eu lists "23Ah", and an owner calls the pack "the 23Ah battery". At 23Ah the pack would be 1,104 Wh and the 15 mph ride below would read 62 miles.
The spec block gives "5-7 hour full charge" and the charger line "54.6V/3A", which is 164 W; 960 Wh divided by 164 W is about 5.9 hours before the charger's losses, inside Ridstar's window. The same owner wrote that "after almost draining it it took about 4:30h".
Filling the pack costs about 18 cents. At 18.31 cents per kWh, the US residential average for July 2026 in the Energy Information Administration's Table 5.6.A, 960 Wh comes to about 18 cents before the charger's losses. A rider who covers 1,000 miles a year at 15 mph on the motor alone, at the model's 17.7 Wh a mile, spends about $3 a year on the same basis.
The maker sells a spare pack. Ridstar's parts store lists a "US / H26" variant at $379, in stock on October 15, 2026, under a product titled "Ridstar Q20/DC26/H20 48V 20AH 15AH Removable Electric E-Bike Battery". That is 47% of our price for the whole bike, and 39 cents per watt-hour if the spare is the same 960 Wh pack, which its variant name does not say.
Range: how far 960 Wh carries the H26 Pro
On level pavement, a 180 lb rider on an H26 Pro modeled at 81.5 lb computes to 54 miles at 15 mph on the motor alone, 39 miles at 20 mph and 83 miles at 15 mph with easy pedaling, on a full pack. Each 1,000 feet of climbing on the motor alone costs the pack about 156 to 205 Wh, depending on the grade, so a hilly route shortens the ride faster than its length suggests.

- Add the climb cost of your route from the hill table, about 156 to 205 Wh for each 1,000 feet on the motor alone.
- Correct for your weight with cargo and the air temperature, then plan on the column that keeps a quarter of the pack in reserve.
Every number in this section comes from one steady-state model. Its inputs are Ridstar's own figures, a comparable motor's published curve, measured fat-tire rolling resistance and a peer-reviewed cycling-power model, and the formula subsection walks one ride through it so you can check the arithmetic.
Email us your cruising speed, your hills, your weight with cargo and your climate, and the model runs your ride. The reply gives the miles for your ride and the reserve the planning column keeps.

How much range does the Ridstar H26 Pro have?
On flat pavement on the motor alone, a full pack computes to 54 miles at 15 mph and 39 miles at 20 mph for a 180 lb rider, and the tables below show how each step in speed, pedaling, load and weather moves that figure.
The first table pairs the motor-only ride with the planning column, and the second shows what steady pedaling adds at each speed. Both use level pavement, the 180 lb rider, an 81.5 lb bike and 77 °F.
| Speed, flat | Per mile | Full charge | With 25% kept |
|---|---|---|---|
| 10 mph | 12.8 Wh | 75 mi | 56 mi |
| 12 mph | 14.5 Wh | 66 mi | 50 mi |
| 15 mph | 17.7 Wh | 54 mi | 41 mi |
| 18 mph | 21.7 Wh | 44 mi | 33 mi |
| 20 mph | 24.9 Wh | 39 mi | 29 mi |
| 25 mph | 34.9 Wh | 27 mi | 21 mi |
| 28 mph | 43.0 Wh | 22 mi | 17 mi |
Miles on a full 960 Wh pack, flat pavement, 180 lb rider, 81.5 lb bike, 77 °F, tires at the median rolling resistance of ten fat-tire tests. The last column keeps 25% of the pack in reserve, the share left after Schmitt, Decker and Doppelbauer (2019) measured a pedelec using 75% of its nominal pack; Ridstar publishes no reserve for this model.
| Speed, flat | Motor only | Easy pedaling (75 W) | Steady pedaling (150 W) |
|---|---|---|---|
| 15 mph | 54 mi | 83 mi | 163 mi |
| 18 mph | 44 mi | 58 mi | 83 mi |
| 20 mph | 39 mi | 48 mi | 62 mi |
| 25 mph | 27 mi | 31 mi | 36 mi |
| 28 mph | 22 mi | 25 mi | 27 mi |
Miles on a full pack at each effort, flat pavement, 180 lb rider, 81.5 lb bike. "Easy pedaling" adds 75 W of rider power and "steady pedaling" 150 W. The first column is the first table's.
At Ridstar's 37 mph the model's motor cannot hold the speed on the flat: its fastest steady speed for a 180 lb rider is 31.9 mph, so the tables stop at 28 mph, where the bike covers 22 miles on a full pack on the motor alone.
Pedaling alone would hold the bike at about 9 mph with 75 W and at 13 mph with 150 W, which is why the effort table starts at 15 mph.
What gears does the Ridstar H26 Pro have?
Seven speeds on ridstar.com: its spec block names "Shimano 7-Speed gears". The motor sits in the wheel, so the gears change your cadence and what your legs add, and no cog choice changes what the motor draws. ridstar.net's September 4 page printed 21 speeds, a front three by a rear seven.
The table therefore shows the energy each ride needs at three efforts, and it is not a gear chart. Pick the gear that lets you hold your effort; the pack feels the difference in your watts and not in your cog.
| Your ride | Motor only | Easy pedaling (75 W) | Steady pedaling (150 W) |
|---|---|---|---|
| 15 mph, flat | 17.7 Wh | 11.6 Wh | 5.9 Wh |
| 20 mph, flat | 24.9 Wh | 20.1 Wh | 15.5 Wh |
| 12 mph, 4% grade | 46.4 Wh | 35.9 Wh | 26.4 Wh |
| 12 mph, 8% grade | 90.1 Wh | 75.7 Wh | 62.6 Wh |
Watt-hours a mile from the pack on the flat and on two grades, 180 lb rider, 81.5 lb bike, at three efforts. The 12 mph rows show what a grade does to a slow ride.
Climbing and the pack
Each foot you climb draws on the pack at a rising rate. On the motor alone, climbing costs about 156 Wh per 1,000 feet at a 4% grade, 170 at 6%, 187 at 8% and 205 at 10%. At a steady 10 mph the cost of a mile rises from 28 Wh at 2% to 224 Wh at 15%.
| Grade | Per mile, motor only | Full charge, motor only | Full charge, easy pedaling |
|---|---|---|---|
| 2% | 28 Wh | 35 mi | 57 mi |
| 4% | 46 Wh | 21 mi | 29 mi |
| 6% | 67 Wh | 14 mi | 19 mi |
| 8% | 92 Wh | 10 mi | 13 mi |
| 10% | 121 Wh | 8 mi | 10 mi |
| 12% | 156 Wh | 6 mi | 7 mi |
| 15% | 224 Wh | 4 mi | 5 mi |
Full-pack miles by grade at a steady 10 mph, 180 lb rider, 81.5 lb bike, on the motor alone and with easy pedaling. The grades run from 2% to 15%.
Ridstar's "Max. Slope 30°" is a slope of 58% grade, far beyond the table, and the listing prints no speed or load for it. The model's motor holds every grade in the table at 10 mph.
What is the Ridstar H26 Pro's weight limit?
Ridstar prints "330 LBS" for the maximum load, and every pound you bring toward it shortens the ride. On the flat at 15 mph, going from a 100 lb load to Ridstar's 330 lb takes the pack from 62 miles to 44 miles. The 8% climb at 10 mph shows the larger drop, from 17 miles to 5.
| You plus your load | 15 mph flat, motor only | 20 mph flat, motor only | 8% climb, 10 mph |
|---|---|---|---|
| 100 lb | 62 mi | 42 mi | 17 mi |
| 130 lb | 59 mi | 41 mi | 14 mi |
| 180 lb | 54 mi | 39 mi | 10 mi |
| 220 lb | 51 mi | 37 mi | 9 mi |
| 260 lb | 48 mi | 35 mi | 7 mi |
| 330 lb | 44 mi | 33 mi | 5 mi |
Rider plus cargo, 81.5 lb bike, on the motor alone, flat pavement unless the column says climb. The heaviest row is Ridstar's own 330 lb maximum load, read as the rider and cargo the bike carries; Ridstar does not define it further.
The bike's own weight is printed twice, and the model runs the heavier figure and shows the lighter one: 81.5 lb from the spec block and 70 lb from the text and the drawing. The lighter case adds about one mile at 15 mph.
| Bike weight | 15 mph flat, motor only | 20 mph flat, motor only | 8% climb, 10 mph |
|---|---|---|---|
| 81.5 lb | 54 mi | 39 mi | 10 mi |
| 70.0 lb | 55 mi | 39 mi | 11 mi |
A 180 lb rider on the motor alone, flat pavement unless the column says climb, at the two printed weights. The first row is the one every other table uses.
Cold and the pack
The cold table uses the cell data of a representative 18650 lithium cell, because Ridstar's page names no cell; the dealer ridstar.eu calls the pack "18650 lithium". At 32 °F the model gives 43 miles at 15 mph on the motor alone for a 180 lb rider, within a bracket of 39 to 45 miles; at 14 °F it gives 39 miles, within 19 to 39.
| Air | Pack energy vs 77 °F | 15 mph flat, motor only |
|---|---|---|
| 95 °F | 99% | 57 mi |
| 77 °F | 100% | 54 mi |
| 68 °F | 98% | 52 mi |
| 50 °F | 93% | 47 mi |
| 41 °F | 91% | 44 mi |
| 32 °F | 89% (80–93) | 43 mi (39–45) |
| 14 °F | 82% (40–83) | 39 mi (19–39) |
Air temperature, the pack's energy against 77 °F, and the 15 mph flat range on the motor alone, 180 lb rider. Brackets are the spread across the cell data read; below freezing the sources disagree most.
Tires and riding position
Across ten measured fat tires, the 15 mph range on the motor alone runs from 50 to 63 miles. The model uses the median rolling resistance of ten fat-tire tests on a drum (0.0105), bracketed by the lowest of the ten (0.0070) and the highest, a knobby Kenda Juggernaut Pro (0.0126). Ridstar's listing names "Chaoyang" as the tire maker and prints no model or pressure, so the bracket covers the range the drum recorded.
Position is the other term. The model uses 0.640 m² for the frontal area of an upright cruiser, from Tengattini and Bigazzi (2018), because Ridstar does not publish the H26 Pro's riding position. Sit lower and the drag falls, which adds range.
| Rolling resistance | 15 mph flat, motor only | 20 mph flat, motor only |
|---|---|---|
| 0.0070 · the lowest of ten fat tires | 63 mi | 43 mi |
| 0.0105 · the median of ten fat tires (used) | 54 mi | 39 mi |
| 0.0126 · the highest of ten fat tires | 50 mi | 36 mi |
Rolling resistance as the drum measured it, with the 15 mph and 20 mph flat ranges on the motor alone for a 180 lb rider on the 81.5 lb bike.
How many miles of range does Ridstar give the H26 Pro?
Ridstar prints four range figures for the H26 Pro, from 44 to 75 miles, and the model reproduces each one as a ride. The two pure-electric figures ask for 18.1 mph (44 miles) and 14.9 mph (55 miles) on the motor alone, the 50-mile figure, whose mode Ridstar does not print, for 16.3 mph, and the 75-mile assist figure for 15.8 mph with 75 W of easy pedaling.
The table gives the steady speed at which a 180 lb rider on the 81.5 lb bike reaches each figure on flat pavement.
| Ridstar's figure | Per mile | Motor only | Easy (75 W) | Steady (150 W) |
|---|---|---|---|---|
| 75 mi, assist | 12.8 Wh | 10 mph | 15.8 mph | 18.7 mph |
| 55 mi, pure electric | 17.5 Wh | 14.9 mph | 18.6 mph | 21 mph |
| 50 mi, mode not printed (battery paragraph) | 19.2 Wh | 16.3 mph | 19.6 mph | 21.8 mph |
| 44 mi, pure electric (spec block) | 21.8 Wh | 18.1 mph | 21 mph | 23 mph |
The steady flat-pavement speed at which the model reaches each of Ridstar's range figures on a full 960 Wh pack, at three efforts, where "Easy" is 75 W of pedaling and "steady" 150 W. The sources are ridstar.com's spec block and battery paragraph and ridstar.net's September 4 page, which is no longer served.
None of the four prints a speed, a rider weight or a terrain beside it. The 44 miles in the spec block, for example, asks for 18.1 mph on the motor alone: a rider who holds that speed uses the whole of what the model gives, and one who rides at 15 mph has 54 miles on a full pack, 41 with the reserve kept.
For a ride with the motor doing the work, the speed table is the figure to plan on.
One owner's reported range is below the model's steady-ride figure. A delivery rider wrote that "the motor drains up the battery quickly if you are constantly braking and accelerating" and that "at 25-30KM/h it does about 30KM, in warmer days it does around 40."
Reading the 40 as kilometers, that is 19 to 25 miles against the model's 54 at a steady 15 mph, so stop-and-go riding and cold cost this owner more than half of the steady figure: one person's account of one bike, on a ride the model does not include (Limitations).
The formula behind the range tables
The power at the wheel is the rolling resistance, plus the climb, plus the aerodynamic drag, and the motor and battery losses are added on top. The model uses the cycling-power form of Martin et al. (1998): power equals speed times the sum of the rolling term, the gravity term and the drag term, divided through the drivetrain, motor and battery efficiencies.
The inputs, each with its source. A number with no row here does not enter the model.
| Input | Value used, with its bracket | Source |
|---|---|---|
| Rider plus bike | 180 lb plus 81.5 lb (118.6 kg); bracket: 70 lb bike, load rows 100 to 330 lb | Central rider; the bike's weight from Ridstar's spec block |
| Pack energy | 48 V × 20 Ah = 960 Wh; bracket: 1,104 Wh at 23 Ah | Ridstar's listing |
| Rolling resistance | 0.0105; bracket: 0.0070 to 0.0126 | Ten fat-tire tests on a drum, median |
| Frontal area × drag | 0.640 m²; bracket: 0.603 m² (mountain bicycle) | Tengattini & Bigazzi (2018), upright cruiser |
| Motor shape | Comparable Bafang curve at 48 V and 1,500 W, no-load speed from 37 mph; bracket: 750 W rated, 2,000 W, 82% efficiency | Bafang OEM workbook 2021 |
| Wheel diameter | 30.01 in for a 26 × 4.0 tire; it sets only the torque a climb needs | Sheldon Brown's tire-sizing table |
| Battery efficiency | Measured curve at the same C-rate; bracket: cell data at 0.5 C | Arango, Lopez & Ceren (2021) |
| Temperature | Air density and cell energy by temperature; brackets in the cold table | NOAA and NASA (1976); LG HG2 cell data |
| Planning reserve | 25% kept in the pack; Ridstar publishes no reserve | Schmitt, Decker & Doppelbauer (2019) |
Each row is a published input, a comparable with its bracket, or a constant, and each is read in the model's own provenance block. Sources are in the references.
One ride, worked through step by step. At 15 mph on flat pavement on the motor alone, a 180 lb rider on the 81.5 lb bike: the rolling term takes 82 W, the drag 114 W, and the wheel receives 196 W. The motor runs at about 77% efficiency at that load, so the battery supplies 256 W, and with the battery's own losses at 97% the cells give up 265 W.
On that 15 mph, 180 lb ride, at 17.7 Wh a mile, 960 Wh carries the bike 54.3 miles, and the planning figure is 40.8 miles.
The model reproduces Martin et al.'s Appendix I values, 45.7 W for the rolling and potential terms and 158.8 W for the aerodynamic term, to the printed digit, and its comparable motor gives 80% at its rated point, the Bafang workbook's published floor. No measured ride of an H26 Pro checks the output, which is the gap Limitations names.
The motor assumption alone moves the 15 mph figure from 54 to as much as 60 miles. If the motor behaved like a comparable rated at 750 W, the 15 mph ride reads 53 miles instead of 54, and 37 instead of 39 at 20 mph; at the 2,000 W rating Ridstar prints for the EU variant it reads 53 and 38, and at 82% motor efficiency 60 and 41.
All the cases come from the same inputs, none is a measurement, and the central figure sits near the middle of them.
Weight and load: two weights, and 330 lb on board
Ridstar prints a 330 lb maximum load for the H26 Pro and two weights for the bike, 81.5 lb in the spec block and 70 lb in the text and the drawing. The listing says "81.5 7LBS" in its "Net weight" row and, further down, "the entire vehicle weighs only 70 pounds", and the same page's gallery drawing prints "70 LBS". The box is "(1603180CM) 45KGS", which is 99 lb.

A Ridstar gallery photograph, scaled uniformly: the saddle, the rack and the tail light. The listing says "Rear Rack: Yes" and "Front Rack: No" and prints no rating for the rack beyond the 330 lb total.
Two other weights sit on the record. The dealer ridstar.eu lists "34 kg", 75 lb, and a delivery rider wrote "36Kg with the battery", 79 lb. The figures run from 70 to 81.5 lb, and the 11.5 lb between them is the size of the unknown.
The same owner wrote that "the vibrations make the rear rack fall off after a few hundred km if you do not tighten the screws a bit", one person's account that is also a maintenance step. Check the rack bolts when the box opens.
If you lift the bike, get its weight in writing before you order. The weight decides the stairs, the trunk and the hitch rack, and a folded bike is lifted whole.
Email us the stairs, the trunk or the rack you have in mind, and our written answer on the weight and the lift comes before you pay. The fold steps and the folded footprint ride in the same reply.
Ask us the bike's weightBrakes, lights and display
Ridstar lists hydraulic brakes on both wheels: its spec block gives "front & rear oil Disc Brakes", and a gallery panel is captioned "Dual Hydraulic Disc Brakes". The photographs show a red caliper on each wheel and a drilled rotor at the front. Ridstar prints no rotor size and no brake maker.

A Ridstar gallery photograph, scaled uniformly: the front wheel with its drilled disc and red caliper.
The spec block puts the lights "on the front fork and the rear lugger", a gallery panel is captioned "Super Bright Headlight", and the text promises "Super bright rear tail light design". It gives no lumen figure for either.
The display is "LCD crystal screen" in the spec block and an "Intelligent LCD digital display meter" in the text, with "mileage statistics, power display, mode switching, speed display and other functions", and the listing adds a 5V USB port for a phone or a light.

A Ridstar gallery photograph at its native 1024 pixels: the headlight, the fork crown and the wordmark on the main tube.
An owner wrote that "some stuff like the plastics of the controls and phone holder break easily", one person's account of one bike, and the phone holder in the cockpit photograph is a plastic clamp on the bar.
At $803.85 on our listing you get hydraulic discs on both wheels, a 960 Wh pack and a hinge, rated by Ridstar for 330 lb of rider and cargo. Checkout takes a credit card or Google Pay, and the freight to the lower 48 is ours.
Order the H26 Pro at $803.85Suspension and tires
Ridstar fits a front fork and a rear shock and puts the bike on 26 × 4.0 tires. The spec block names a "suspension front fork" and the text a "front and rear shock absorption system, combined with wide tire design, no fear of bumps", with "a 700lbs back shock absorber". Ridstar prints no travel for either end and no unit for the 700.
The tires are "26inch 4.0 Chaoyang fat tires" on a "26inch Aluminum alloy single deck spoke rim", and Ridstar's listing names fenders front and rear in "HCS". It names no tire model and prints no pressure. Our range model brackets the rolling resistance between the lowest and the highest of ten measured fat tires.
An owner wrote: "The wheels are amazing, sturdy and very good on sand and wet dirt." The same post says: "The tires while good offroad are stupidly bad in the rain (for city)". Those are one rider's opinions at 500 km, and a tire pressure or a different tread is a change a rider can make.
The Mercer fit test
Seven members of the Mercer family, the fixed archetypes we hold every reviewed bike against, are set against the H26 Pro. Each row reads Ridstar's two windows, the model's saddle figure for that height, and the load rating or the law in the class section; the people are archetypes and never testers.
| Member | Age · Height | Verdict | The number behind it |
|---|---|---|---|
| Frank Kowalski | 63 · 5'10" | Inside both windows | Saddle top 36.8 in above the pedal axle by the formula; the bike's weight is printed as 70 and as 81.5 lb |
| Ruth Kowalski | 61 · 5'5" | Below both windows | Saddle top 33.8 in by the formula; ask for the seat height before you order |
| Jack Mercer | 48 · 6'1" | Inside both windows | Saddle top 38.8 in by the formula; his weight plus gear up to Ridstar's 330 lb |
| Dana Mercer | 45 · 5'7" | At the bottom of one window, inside the other | Saddle top 35.1 in by the formula; Ridstar prints a 330 lb load and no passenger rating |
| Maya Torres | 32 · 5'6" | At the bottom of one window, below the other | Saddle top 34.5 in by the formula; read the class section before a commute |
| Cole Mercer | 16 · 5'11" | No | 1,500 W and 28 mph or more sit above the e-bike limits in the class section |
| Ivy Mercer | 12 · not in the family's record | No | Above the e-bike limits on Ridstar's own figures, so off the table at her age |
The people are the Mercer family. Heights and ages are theirs; the saddle figures are the model's at each height, from the ANSUR II survey.
Jack and Ruth sit on opposite sides of Ridstar's windows. Jack at 6'1" is inside both, and Ruth at 5'5" is below both, so the seat height Ridstar prints once, "105CM", and the seat height she needs are the figures to compare in writing.
Dana at 5'7" and Maya at 5'6" sit at the edge of the two windows, where the page prints two answers. Cole is 16 and Ivy is 12, and on Ridstar's own figures the bike sits above the e-bike limits in the class section, so neither row is a yes.
Is the Ridstar H26 Pro UL certified?
None of Ridstar's H26 Pro pages, and none of the 14 images on the ridstar.com listing, prints a UL standard, a certificate holder or a file number for the bike, the pack or the charger. UL Solutions certifies e-bikes to UL 2849, which examines the drive train, battery and charger as one system. The listing's text, and ridstar.net's September 4 text, name no safety standard at all.
A certificate has a holder's name and a UL file number, and a seller can be asked for both before you pay. If a certificate on paper decides your purchase, VTUVIA's SF20H page prints "UL2271 & UL2849 Safety Certified" beside its specifications, and the same two questions apply there.
Has the H26 Pro been recalled?
No. The CPSC's recall list carries no Ridstar recall, and the Commission's two Ridstar warnings name the Q20, the Q20 Pro and the Q20 Lite, and not the H26 Pro. On October 15, 2026 the whole recall list, 10,047 records to the newest recall of October 8, 2026, held no Ridstar, Xingqishi, HK Ridstar or YVY term and no record naming an H26, and the Commission's recall feed of 40 items held none either.
A warning is not a recall, and no recall also means no recall remedy for any Ridstar model. The CPSC recall search is the place to check the bike again before you buy, and the next section sets out what the two warnings say.
The maker's record
Two CPSC stop-use warnings, a UK safety report and two lawsuits concern Ridstar bikes, and none of them names the H26 Pro. The record concerns the company you would be buying from, so it is set out here in full, in the regulators', the courts' and Ridstar's own words as they printed them.
| Warning | Models named, as printed | Hazard, as printed | What the Commission reports |
|---|---|---|---|
| 26-337, March 19, 2026 | "Ridstar Q20 and Q20 Pro e-bikes" | "The e-bikes' batteries and wires can ignite, posing a fire hazard to consumers." | "11 reports of fire, including one burn injury, five reports of smoke inhalation, and two reports of property damage totaling over $40,000" |
| 26-584, June 25, 2026 | "Ridstar Q20 and Q20 Lite e-bikes" | "The front wheel can detach without warning, posing a crash hazard to consumers." | "32 reports of the front wheel detaching, including 31 reports of injuries" |
Both rows as the Commission printed them, re-read word for word on October 15, 2026.
The Commission names the manufacturer in both releases as Huizhou Xingqishi Sporting Goods Co., Ltd., of China. The first says it "has refused to agree to an acceptable recall", and the second that it "has been unresponsive to CPSC's requests for information about these products or a recall." The first also prints the company's reply: "The company objects to this press release."
What the record does not say. Neither warning names the H26 Pro, and neither the Commission nor Ridstar publishes whether the H26 Pro shares the warned bikes' batteries, wiring or front-wheel hardware.
Both releases tell owners how to identify the bikes: they are black, "the brand name Ridstar is printed on the battery", and the model number sits "on the purchase receipt", "Q20 or Q20 Pro" in the first and "Q20 or Q20 Lite" in the second. The H26 Pro in Ridstar's photographs is black and carries the Ridstar name on its frame, so if you own any Ridstar, the model number on your receipt is the line to read.
No warning, report or suit on this record names the H26 Pro, no Ridstar recall exists, and nothing published says whether the H26 Pro shares the warned bikes' parts.
Britain has its own record. The Office for Product Safety and Standards reported Ridstar's "Q20-Plus, Q20-Mini, E26 Pro and Chargers" as a serious fire risk on June 19, 2025, because "the charger has poor quality soldering, and the transformer does not meet the minimum requirements for creepage and clearance distances." The import "has been rejected at the border." The report does not name the H26 Pro.
Two product-liability suits allege that a Ridstar front wheel came off: the Oregon suit against Amazon, No. 3:26-cv-00692, over a "Ridstar Q20", and the Florida suit against Walmart, No. 9:26-cv-81045, over a "Ridstar Electric Bike, Peak 1500W30MPH,48V 15.6Ah".
Both are allegations, and as CourtListener held the dockets on October 15, 2026, neither shows a ruling on the claims; the Florida docket shows a motion to dismiss and its briefing, and no ruling on it. Neither names the H26 Pro, and Ridstar is not a named defendant in either.
Who you would be buying from. Ridstar's company page names its business as "HK RIDSTAR TRADE LIMITED", at an address in Hung Hom, while ridstar.net's September 4 page for this bike said "Established in New Jersey and proudly serving the US since 2008." YVY's own company page names the same business, HK Ridstar Trade Limited, so YVY and Ridstar bikes come from one company.
Which Ridstar store you would be buying from. ridstar.net prints "Official Statement of Ridstar: Except ridstar.net, other similar websites are our dealers" and "The only official website of ridstar", yet its own catalog no longer lists the H26 Pro, while ridstar.com's listing sells it and says "The Ridstar Warranty Policy is only available to customers ordering from ridstar.com." The buying section sets out what that means for a bike bought from us.
Our Ridstar profile sets out the whole brand: its four storefronts, the warnings, the suits and every Ridstar model we list. Each Ridstar review links back to it.
Read our Ridstar profileNo e-bike class fits the H26 Pro's figures
On Ridstar's own figures, a 1,500 W motor, or a 2,000 W one, and a top speed of 28 or 37 mph sit outside the definitions the e-bike classes are built on, and Ridstar's pages assign the H26 Pro no class. Read your state's definition before any ride on a public road, lane or path.
At the federal level, 15 U.S.C. § 2085(b) defines a low-speed electric bicycle as one 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."

| Motor | 1,500 W for the US variant, "up to 1500W peak" in its text, 2,000 W for the EU variant; no continuous rating printed | "less than 750 watts (1 h.p.)" | "does not exceed 750 watts of power" |
| Top speed on the motor | 37 mph (spec block); 28 mph (carousel panel and text) | "less than 20 mph" | class 2 stops assistance at "20 miles per hour" |
| Pedals | yes | "fully operable pedals" | "fully operable pedals" |
Statute text read October 12, 2026 at govinfo and California's legislative site; Ridstar's figures from its listing, read October 15, 2026.
In California the motor alone takes the H26 Pro outside the electric bicycle definition at either rating, because § 312.5(a) tests a motor that "does not exceed 750 watts of power" and Ridstar prints 1,500 W and 2,000 W. The US figure is called a peak in one paragraph and given no continuous value, and the statute does not say which one counts.
The code's definition of a motorized bicycle or moped, § 406(a), asks for "fully operative pedals", "an automatic transmission" and "a motor that produces less than 4 gross brake horsepower" with a top speed "of not more than 30 miles per hour on level ground".
A 1,500 W motor is about 2.0 horsepower and a 2,000 W motor about 2.7, both under 4. Ridstar's 28 mph sits under the speed limb and its 37 mph above it, and the page prints both.
Ridstar names "Shimano 7-Speed gears", and whether that is "an automatic transmission" is a question for the California Department of Motor Vehicles and our California page; this review does not decide it.
Our census of the 51 state definitions, the 50 states and DC, read September 24, 2026, found 44 that set a 750-watt motor limb, California's among them, and Rhode Island's "rated not more than two (2) (S.A.E.) horsepower", about 1,491 W.
At 1,500 W the H26 Pro is above the 44 that set 750 watts, and at 2,000 W it is above all 45. It is also about 9 W above Rhode Island's, if 1,500 W is its rating.
Four definitions set no power figure, the District's, Montana's, New Jersey's and Oregon's, and Alaska and Kentucky define no electric bicycle. Our 50-state atlas sets out each one from its statute, with the speed limits that decide a bike in the states that set no wattage.
On Ridstar's own figures the H26 Pro is outside the California e-bike definition at either motor rating, and its motor is above the 750-watt limb of 44 of the 51 state definitions we read. Read your state's definition before any ride on a public road or path.
Where you can ride it
A path or trail that admits e-bikes by class admits this machine only if its own posted wording says so, and on Ridstar's figures no class covers the H26 Pro. In California, if the bike is read as a motorized bicycle, § 21207.5(a) keeps it off "a bicycle path or trail, bikeway, bicycle lane" unless the path is "within or adjacent to a roadway" or a local ordinance permits it.
| Where you want to ride | Who sets the rule | The document to read |
|---|---|---|
| A street or a bike lane | your state, then your city | the state's definitions (our atlas) |
| A multi-use path or park trail | the park or trail agency | the class wording posted at the trailhead |
| A National Forest trail | the Ranger District | the motor vehicle use map (36 CFR 261.13) |
Each rulebook reads its own posted wording first, and the specification matters once that wording names watts or speed.
National Forest rules define a motor vehicle as "any vehicle which is self-propelled, other than" a vehicle operated on rails or a wheelchair or mobility device (36 CFR 261.2), and a breach of a Part 261 rule carries "imprisonment of not more than six months or a fine in accordance with" the federal criminal code (36 CFR 261.1b). Our public-land guide covers each federal land agency.
Green flags / Red flags
The green flags are checkable facts on Ridstar's pages and ours. Each red flag ends in something you can do before you buy or ride.
Green flags
- A 960 Wh pack for $803.85. About 84 cents per watt-hour at our price, against 139 cents for the Samebike LO26 Plus and 193 for the VTUVIA SF20H.
- It folds, and two Ridstar pages agree on the folded size. The drawing and ridstar.net's September 4 page both print about 39 by 39 inches, 28.7 inches deep.
- In stock at the maker's US store and buyable here. Ridstar's ridstar.com listing showed the US variant in stock on October 15, 2026, and our listing took orders that day.
- A load rating and a rider window are published. Ridstar's page prints 330 lb and two windows, 5.5 to 6.2 ft and 5'7" to 6'7".
- The maker sells the parts. ridstar.net lists H26 or H26 Pro variants of a pack, a motor, a controller and a charger, all in stock that day.
- Hydraulic brakes on both wheels, a front fork, a rear shock and seven speeds, in Ridstar's own words.
Red flags
- On Ridstar's own figures no e-bike class covers it. Read your state's definition first; for a 750 W bike inside a class, look at the VTUVIA SF20H.
- Ridstar prints two motors, two weights, two speeds and two rider windows under one name. Email us and we will answer in writing which motor and pack the unit on our listing carries, before you order.
- The bike's weight is printed as 70 and as 81.5 lb. The weight section runs both and the range tables show the difference, so get the figure you need in writing before you lift it.
- The maker's record includes two CPSC warnings on other models and no recall. Read the record; for the same folding format from a maker no CPSC notice names, look at the Samebike LO26 Plus.
- Ridstar's statements limit after-sales service to buyers from its own stores. Read our warranty answer and ask us in writing which terms apply before you buy.
- No UL standard, certificate holder or charger rating is printed. The UL section says what to ask a seller for, and the VTUVIA SF20H prints "UL2271 & UL2849 Safety Certified".
Buy it if / Buy something else if
Buy it if you want a fat-tire e-bike that folds to about 39 by 39 inches, you are between 5'7" and 6'2", inside both of Ridstar's windows, and you ride where your state's rules take a motor Ridstar prints at 1,500 W and at 2,000 W.
At $803.85 the pack costs about 84 cents per watt-hour, and charging for 1,000 miles a year at 15 mph on the motor alone costs about $3 a year.
Buy something else if you ride bike lanes or paths that admit e-bikes by class. The VTUVIA SF20H, $1,299 on our store on October 15, 2026, prints "750W Motor Power" and "UL2271 & UL2849 Safety Certified" on VTUVIA's page, lists "Speed Class 2" among its specifications, and folds, with a 672 Wh pack and a 60 lb net weight that includes its rear racks and fenders.
VTUVIA showed the SF20H in stock in White and Black that day, and our SF20H review computes its range and fit for your height and route.
Buy something else if you want the same 26-inch folding format from a maker no CPSC notice names. The Samebike LO26 Plus, $999 on our store, lists "Motor 1000W Peak Motor 1500W", a "48V 15Ah" pack of 720 Wh and "26*3.0 inch" tires on Samebike's page.
Samebike showed it in stock in Black, White, Gray and Navy on October 15, 2026. Its printed figures sit above the 750-watt line as the H26 Pro's do, so the class question is the same, and our LO26 Plus review computes its range and fit.
Buy something else if you need the store that sold you the bike to hold the maker's warranty. Ridstar's statements and our policy are set side by side in buying it from us; ask us in writing before you order.
Our SF20H review computes the range and fit of the 750 W folding fat-tire bike on our shelf, from VTUVIA's own figures. Its page prints UL2271 and UL2849, and it is the folding bike we point to for rides on paths that admit e-bikes by class.
Read our SF20H reviewBefore you buy: the checklist
Six checks cover the H26 Pro: your state's definition, your inseam and the seat height, the weight and folded size Ridstar prints two ways, the maker's record, the figures to ask for, and the first week of riding.
- Read your state's definition and the posted class wording on any path you plan to use, in our atlas.
- Measure your inseam and read your row in the saddle table before you order.
- Settle the weight and the folded size if you lift or store the bike: the weight section runs 70 to 81.5 lb, and the figure you need is the one in writing.
- Read the maker's record and our warranty answer, and ask us anything they leave open.
- Ask for the missing figures in writing: which motor and pack the unit carries, the top speed, the charger rating, and a UL certificate holder and file number if you want one.
- In the first week, inspect the delivery within 48 hours, check the axle nuts and the rear rack bolts, and set the saddle with the heel check.

Read October 15, 2026 from our shipping policy, our refund policy and our checkout.
Change-of-mind returns are for unopened bikes in factory-sealed packaging, requested within 72 hours of delivery, with a 15% restocking fee and the return freight, and an order cancellation carries a 3% transaction fee, as our refund policy sets out.
Who repairs it is the question to settle before you buy. Ridstar's official statement says: "Except for customers who purchase from ridstar.net, we will not provide any after-sales service to customers who purchase ridstar products from other places." ridstar.com's listing says "The Ridstar Warranty Policy is only available to customers ordering from ridstar.com." Our refund policy says a power, charging or component fault "is covered under manufacturer warranty — we coordinate repair or replacement remotely."
For a bike bought here those statements do not agree, and this review does not settle the disagreement. Ask us in writing which applies to the unit you are offered, and we will answer before you order.
Our price is $803.85, and we pay the freight within the contiguous United States. Ridstar's own ridstar.com asked $1,399.00 for its US variant that day, and ridstar.net no longer lists the bike.
Your H26 Pro, $803.85Frequently asked questions
What is the Ridstar H26 Pro?
The Ridstar H26 Pro is a folding 26-inch fat-tire electric bike that Ridstar lists on ridstar.com, $1,399.00 for its US variant. Ridstar prints a 1,500 W motor for that variant and 2,000 W as dual motors for the EU one, a 48V 20Ah pack that is 960 Wh by arithmetic, 26 × 4.0 tires, a front fork, a rear shock, hydraulic discs and a 330 lb load. The specification table quotes each figure.
Is the Ridstar H26 Pro 1500W or 2000W?
Ridstar prints both. Its ridstar.com spec block gives "48V 1500W (US/CA/UK warehouses)" and "52V 2000W (Dual 1000W motors)(EU warehouse)", and ridstar.net's September 4 page called the motor a PEAK 2000 W. Our listing's title says 2000W, so ask us in writing which motor the unit carries.
Does the Ridstar H26 Pro have a dual motor?
Ridstar's pages point both ways. The headline says "1500W Dual Motor", the spec block places the motor "On the F&R wheel and rear luggger", the US variant lists "48V 1500W" as one figure, and the EU variant lists "Dual 1000W motors". The photographs show a motor hub at the rear wheel and a plain hub at the front, and the question to ask us is which configuration ships.
How fast does the Ridstar H26 Pro go?
Ridstar prints "37 MPH" in its spec block, "28 MPH" on its carousel panel and "a top speed of 28 mph" in its text; ridstar.net's September 4 page said "28+++ mph". The range model's motor holds 31.9 mph on flat pavement with a 180 lb rider. No measured top speed is published, so ask for one in writing before you rely on any of them.
How far can the Ridstar H26 Pro go on one charge?
The model computes 54 miles at 15 mph on the motor alone, 39 at 20 mph and 83 at 15 mph with easy pedaling, on flat pavement with a 180 lb rider. Keep a quarter of the pack in reserve and plan on 41 miles at 15 mph on the motor alone. Ridstar prints four figures from 44 to 75 miles and no speed beside any of them, and the range section shows the ride each one asks for.
How much does the Ridstar H26 Pro weigh?
Ridstar's spec block says "81.5 7LBS", while its text and its drawing say 70 lb; the dealer ridstar.eu lists "34 kg", 75 lb, and an owner wrote "36Kg with the battery", 79 lb. The box is 45 kg. If you lift the bike, get the weight in writing before you order.
What battery does the Ridstar H26 Pro have?
A removable 48V 20Ah pack on ridstar.com's US variant, 960 Wh by arithmetic. The product's handle reads "23ah" and the dealer lists 23Ah, which would be 1,104 Wh. Ridstar's parts store sells a spare for $379; ask which pack you would receive.
Is the Ridstar H26 Pro street legal?
On Ridstar's own figures its motor alone puts it outside the federal low-speed electric bicycle definition and outside California's electric bicycle definition at either rating, and it is above the 750-watt limb of 44 of the 51 state definitions we read. Your state decides whether and where a machine of this power may ride; the class section has the detail.
Is the Ridstar H26 Pro named in the CPSC warnings?
No. The Commission's two Ridstar warnings, on fires and on front wheels, name the Q20, the Q20 Pro and the Q20 Lite, and neither names the H26 Pro. Neither the Commission nor Ridstar publishes whether the H26 Pro shares the warned bikes' parts, and no Ridstar recall exists; the record section quotes both warnings.
Is there a Ridstar H26 Plus?
Not on Ridstar's US stores. The dealer ridstar.eu lists an "H26PLUS" at 2,000 W with dual 1,000 W motors for €1,499, but none of ridstar.net's 85 product titles or ridstar.com's 55 names an H26 Plus on October 15, 2026. ridstar.com's EU variant of the H26 Pro carries the same "Dual 1000W motors".
How do you fold the Ridstar H26 Pro?
Ridstar's listing says "3-second folding" and "one-button folding" and prints no steps. An owner wrote "just take the battery out while half folded so it is easier". Folded, two Ridstar pages agree on about 39 by 39 inches and 28.7 inches deep; the folding section sets out the sizes.
Where is the Ridstar H26 Pro manual?
No H26 Pro manual is linked. The page titled "Ridstar/YVY User Manual" on ridstar.com holds return-policy text and links no manual, and the same address on ridstar.net answered 404 on October 15, 2026. Ask us for the torque, tire pressure and charger figures in writing before you order.
How tall do you need to be for the Ridstar H26 Pro?
Ridstar's page prints two windows, "5.5- 6.2 Ft" in its spec block and "5'7" -6'7"" on its carousel panel, so 5'7" to 6'2" is inside both. If you are 5'10" with the Army survey's median inseam of 33.8 inches, the formula sets the saddle top 36.8 inches above the pedal axle; the saddle table gives each height.
Which Ridstar website sells the H26 Pro?
On October 15, 2026 ridstar.com sold the US variant at $1,399.00, the dealer ridstar.eu listed an H26 PRO at €1,199, and ridstar.net no longer listed it, though its statement calls itself "The only official website of ridstar". Service for a bike bought elsewhere is Ridstar's to state, and for a bike bought here buying it from us states ours.
Is the Ridstar H26 Pro worth it?
At $803.85 it gives 960 Wh, about 84 cents per watt-hour, and a hinge. It is worth it if you want a folding fat-tire bike, ride where a motor of this size is allowed and have weighed the maker's record; if not, the verdict names the bikes to read instead.
Limitations of this review
Each item below is a limit on what this page can tell you about the H26 Pro, and what that limit means for your own decision.
- Ridstar's figures disagree, and each is printed. The motor is 1,500 W and 2,000 W; the top speed 37 and 28 mph; the weight 81.5 and 70 lb; the rider window 5.5 to 6.2 ft and 5'7" to 6'7"; the range 44, 50, 55 and 75 miles; the folded size three ways; and the pack 20Ah and 23Ah.
- Which motor and pack our unit carries is not published. Our listing's title says 2000W, ridstar.com's US variant says 1,500 W, and this review prints both and does not decide.
- Our own listing's text predates parts of this page. On October 15, 2026 our listing's title and text carried the 2,000 W, 21-speed, 70 lb and 5'7" to 6'7" figures of ridstar.net's removed page; where they differ from ridstar.com's current page, this review prints both.
- The page ridstar.net removed is read from its record. Its September 4, 2026 capture and our August 26 deposit are the sources; the live address answered 404 on October 15, 2026.
- The motor in the range model is a comparable whose curve is not the H26 Pro's own. Bafang's published curve is rebuilt at 48 V and 1,500 W with its no-load speed set from Ridstar's 37 mph, and the sensitivity cases move the 15 mph figure from 54 to as much as 60 miles.
- The tire's outer diameter is derived. Ridstar prints a 26 × 4.0 tire and no outer diameter, and the model uses 30.01 inches from the ISO bead seat plus twice the tire width; it sets the torque a climb needs and does not change the flat-road figures.
- The model runs the 20Ah pack. At 23Ah the same ride reads about 15% farther.
- No ride of an H26 Pro to an empty pack is used in the model. One owner reported 30 to 40 km at 25 to 30 km/h in stop-and-go delivery riding, a ride the steady-state model does not include, so the tables are an upper envelope for a smooth ride.
- The tires were not measured. Ridstar names Chaoyang and no model, so the bracket covers the ten fat tires the drum recorded.
- The cold table uses LG HG2 cell data, and Ridstar names no cell; the dealer lists 18650 cells. The brackets widen below freezing.
- The speed behind each of Ridstar's four range figures is not printed, so the maker's band shows the rides they would take.
- Ridstar's drawing letters its dimensions without naming them. Only the handlebar height matches one of the listing's two geometry lines, so the standover, the cockpit lean and the hand load are not computed and the saddle figures are the formula's.
- The fit tables use the US Army's ANSUR II survey, 4,082 men and 1,986 women, a population different from the general public. Your own inseam outranks any row.
- The saddle formulas are averages. Published recommendations run from 106% to 110.4% of inseam, and the heel check is the test on your own leg.
- Ridstar's pages carry no UL certificate to read. None of the page's text or its 14 images prints a UL standard, a certificate holder or a file number.
- The warnings, the UK report and the suits do not name the H26 Pro, and nothing published says whether it shares the warned bikes' parts; this review does not say either way.
- No H26 Pro manual is linked. The page titled "Ridstar/YVY User Manual" on ridstar.com holds a returns policy, and the same address on ridstar.net answered 404, so the torque, tire pressure and charger figures a manual might give are unknown here.
- Four r/ebikes posts by two owners name the H26 Pro. Each is one person's account, none is totaled with another, and the replies were not read.
- The store comparison covers ridstar.net, ridstar.com and ridstar.eu. ridstar-ebike.com answered every request with a captcha and ridstar.uk answered 404 on every route on October 15, 2026, so those two could not be read.
- The state census is a reading of statutes as published on September 24, 2026. A change after that date is outside it; our atlas carries each state's current definition.
The bottom line
Buy the Ridstar H26 Pro if you want a folding fat-tire bike with a 960 Wh pack for $803.85, you are between 5'7" and 6'2", and you ride where your state's rules take a motor Ridstar prints at 1,500 W and at 2,000 W.
On flat pavement it computes to 54 miles at 15 mph on the motor alone for a 180 lb rider, 41 with a quarter kept in reserve, and charging for 1,000 such miles a year costs about $3 a year.
Read the maker's record and our warranty answer before you order, and ask us which motor and pack your unit carries. If you ride bike lanes or paths, the VTUVIA SF20H is the folding bike with a printed 750 W motor; if you want the same 26-inch format from a maker no notice names, the Samebike LO26 Plus is $999.
This button opens checkout for the H26 Pro at $803.85, our price on October 15, 2026, with free shipping within the contiguous United States. Our shipping policy dispatches an order within 1–3 business days of confirmation and emails you the tracking number when it ships.
