Federal safety warning, read before anything else on this pageThe US Consumer Product Safety Commission has told consumers to stop using the Ridstar Q20 Pro immediately over a battery fire hazard, and its instruction is not to sell it or give it away. We list it, and the Commission's words open this description so that you read them first.
The March 19, 2026 warning covers the "Ridstar Q20 and Q20 Pro e-bikes": "The e-bikes' batteries and wires can ignite, posing a fire hazard to consumers." The Commission "is aware of 11 reports of fire, including one burn injury, five reports of smoke inhalation, and two reports of property damage totaling over $40,000." Its instruction: "remove the battery from the e-bike immediately and dispose of the battery following local hazardous waste disposal procedures. Do not sell or give away these hazardous batteries."
Neither notice is a recall, and there is no repair, refund or replacement program. The March notice states that "the manufacturer, Huizhou Xingqishi Sporting Goods Co., Ltd., of China, has refused to agree to an acceptable recall"; the June notice states that it "has been unresponsive to CPSC's requests for information about these products or a recall."
Before either US notice, the UK Office for Product Safety and Standards published Product Safety Report 2506-0011 on 19 June 2025 for the "Ridstar E-Bikes Q20-Plus, Q20-Mini, E26 Pro and Chargers", risk level "Serious": "the charger has poor quality soldering, and the transformer does not meet the minimum requirements for creepage and clearance distances." Its corrective measure: "The import has been rejected at the border."
Two product-liability suits over a detached Ridstar front wheel were filed in 2026 and are undecided: Cunanan v. Amazon.com Services LLC (D. Or., filed April 7, 2026) alleges a Ridstar Q20 caused "numerous facial fractures"; L.E. v. Walmart Inc. (Palm Beach County, filed July 30, 2026, removed to S.D. Fla.) alleges a Walmart-bought Ridstar's front wheel "unexpectedly detached during normal operation" and injured a minor. Both are allegations, not findings.
If you already own one: the Commission's instruction is to stop riding it and dispose of it through your local household hazardous-waste program, not to sell it or give it away. The full record, the lineup, and the models no regulator has named are in our Ridstar brand profile, verified September 11, 2026.
A 52-volt pack and a motor at each end. What the Q20 Pro sells you is traction, and traction is not a number on a spec sheet.
Both wheels drive. That is the whole argument for the Q20 Pro, and no tire choice substitutes for it.
Quick answerThe Q20 Pro is Ridstar's dual-motor Q20 at $1,369: two motors, a 52V 20Ah pack (1,040Wh), hydraulic dual brakes, dual suspension and 20x4.0 tires. It is the Q20 to buy for loose ground and two-wheel drive. Order it here for free US shipping, Shop Pay instalments, and a US warranty claim we file for you.

Why this bike
Two-wheel driveA motor at each end, and grip you cannot buy with tires
Put a single-motor fat bike on wet grass, loose gravel or a sand track and the rear wheel spins while the front just steers. The Q20 Pro drives both. You get out of the soft stuff by rolling on rather than by paddling, you climb loose ground seated, and you stop breaking traction every time the surface changes. Ridstar publishes brushless motors at both ends with a combined 2000W output.
52-volt platform1,040 watt-hours, at 52 volts instead of 48
Only this bike and the Q30 Pro run 52 volts in our Ridstar range; everything else is 48. Higher voltage moves the same power at lower current, which means less heat in the controller and the wiring on a long climb. It is the one advantage on this bike that does not depend on how anybody words a spec sheet. The 1,040 watt-hours is Ridstar's published 52 volts multiplied by its published 20 amp-hours.
Brakes and suspensionHydraulic brakes at both ends, suspension at both ends
This is the heaviest bike in the Q20 family and the only one specified to stop like it. Hydraulic brakes pull harder for less hand pressure, which is what you want on a loaded fat bike coming downhill, and they stay consistent when the levers get wet. Suspension front and rear is the difference between riding a rutted fire road and enduring it. It is the most complete component list Ridstar publishes anywhere in the Q20 range.
Tires and gearing20 x 4.0 fat tires and a 7-speed drivetrain
Four-inch tires at 20 inches float over sand, snow and broken ground that would stop a commuter bike, and they let you run low pressure for grip without pinch-flatting. The 7-speed drivetrain means you still have gears when the battery is low or the climb is long — you are never left with one ratio and a tired pack.
Why buy the Q20 Pro here
$1,369 here. The same Q20 Pro is listed at $1,760.95 on ridstar.com, Ridstar's other storefront, checked 29 August 2026 — $391.95 more for the identical machine, and that is before freight. Ours ships free in the lower 48.
Free US shipping
Your Q20 Pro ships free anywhere in the lower 48, with tracking emailed the day it leaves. Nothing is added at checkout: the $1,369 on this page is the $1,369 you pay.
Pay over time
Shop Pay instalments are live at our checkout, so you can split the $1,369 into payments instead of putting it on a card in one go. You pick it at the payment step.
We file the warranty claim
If something covered fails, you send us photos and we take it from there — we file and track the claim, and arrange the part or the replacement. You never deal with the factory, and you never pay to be helped.
A US company answers
Support, warranty handling and returns are all run from here, in your timezone, under US consumer law. One storefront, one set of terms, one company that has to stand behind the sale.
That last one is worth more on this brand than on most. Search “Ridstar” and four storefronts come back, each presenting itself as the official one, at prices that differ by hundreds of dollars for the same machine — and they do not share return terms. Ridstar.net publishes a statement on its own site that reads, in full: “Except ridstar.net, other similar websites are our dealers. We hope that all customers can find the right merchants to make purchases, so that they can get the best, most complete and most timely after-sales service.” Buying the Q20 Pro here removes that question entirely: the terms below are ours, they are the ones that govern your order, and the specifications on this page come from one named listing on ridstar.net/products/ridstar®-q20pro-2000w-fat-tire-ebike, retrieved 2026-08-26 with the U.S. market forced.
The full working on which Ridstar domain is which — registration dates, contact addresses, the dealer statement and what stays unresolved — is in our Ridstar brand profile. Source: Ridstar Official Statement, retrieved 2026-08-26. Ridstar's own return policy charges 15% processing fee plus $200 return shipping per e-bike on a cancellation after despatch, and ridstar.com, the other storefront, publishes a different set: a 14-day window and a 25% restocking fee. Two storefronts, two return policies, same brand. Those terms govern an order placed with Ridstar. Yours is placed with us.
Is the Q20 Pro the right one for you?
Buy it if
- You ride loose ground — sand, gravel, wet grass, snow — where two driven wheels change traction in a way no tire choice matches
- You want the 52-volt platform rather than 48: higher voltage moves the same power at lower current, and only two bikes in our Ridstar range publish it
- You want hydraulic brakes at both ends and suspension at both ends on one bike — the most complete component list in the Q20 family
- You want the flagship of the Q20 family rather than a variant of it — the 52-volt pack, both motors, and the full brake and suspension specification on one bike at $1,369
Or one of these instead
- Riding pavement and commuting most days? The Q20 1500W is the single-motor version at $909 — one published motor rating, 48V 20Ah, the same hydraulic dual brakes.
- Range is what you are optimising for? The Q50 carries 48V 25Ah — 1,200Wh, the largest pack we can ship today — at $799.
- Want more published power for less money? The Q30 Pro is the same 52V 20Ah dual-motor platform with a 4000W rating, at $1,269.

Warranty, filed by us
A one-year limited warranty from Ridstar Bikes, running from the original owner's receipt or purchase date, whichever is later, as verified by Ridstar. Redtail files and tracks the claim for you; you do not deal with the factory.
Change-of-mind returns run on unopened, factory-sealed items requested within 72 hours of delivery, at a 15% restocking fee plus return shipping — against Ridstar's own return policy, which charges 15% processing fee plus $200 return shipping per e-bike direct, and ridstar.com, the other storefront, publishes a different set: a 14-day window and a 25% restocking fee. Two storefronts, two return policies, same brand. Cancellations carry a 3% transaction fee because card processing is non-recoverable. Full terms: Redtail Shipping Policy · Redtail Refund & Return Policy. Alaska, Hawaii, U.S. territories, P.O. boxes, and remote areas may incur extra charges or be excluded — contact us before ordering.

What it covers
This Limited Warranty covers any defects in hardware or firmware under regular use during the Warranty Period.
What you must do
- Keep the purchase proof — Ridstar states a claim without an invoice or receipt is not covered
- Register the claim through the seller you bought from; Redtail files it for you
- Keep the original packaging for a while after delivery — Ridstar asks for this on its own product listings
Not covered
- Anything not resulting from a hardware or firmware defect
- Claims made after the warranty period, which Ridstar handles at material cost instead
- Claims with no associated purchase proof
A one-year limited warranty issued by Ridstar Bikes, beginning from the original owner's receipt or purchase date, whichever is later, as verified by Ridstar, as published on its warranty page and retrieved 2026-08-26. One caveat worth knowing: Ridstar's own product listings print a bullet headed "ONE-YEAR WARRANTY" that then states a warranty on the motor, battery and charger — on some models one year, on others two — while its warranty page states one year for the whole bike. Every page states the figure from that model's own listing and says the page disagrees.
How the Q20 Pro compares with the rest of our Ridstar range
Ridstar's Q20 name covers several different bikes — Luxe Lite, Luxe, the 1500W “Upgraded” and the Pro — from 1000W to 2000W and 720Wh to 1,040Wh. The Q20 Pro against the three other Ridstars we can ship today, side by side.

Specifications as published by Ridstar at ridstar.net/products/ridstar®-q20pro-2000w-fat-tire-ebike, archived 2026-08-26 — read out of the copy on that page — Ridstar publishes no specification table for this model, so every figure above traces to a sentence in its own description, and the sentence behind each one is on file. Watt-hour totals are our arithmetic from Ridstar's own volts and amp-hours and are marked as such. These are the manufacturer's ratings, not our test results.
Where Ridstar's own material prints more than one figure, the row above carries the value this page uses and the alternate is recorded here: Ridstar also prints 1000W for this bike in a separate line, and publishes no per-motor rating anywhere; Ridstar also prints “front and rear suspension” alongside “dual suspension”.
How to read this spec sheet
Manufacturer pages carry marketing, and marketing sometimes disagrees with the marketing an inch below it. Every place Ridstar's own material disagrees with itself for this model, every figure it leaves out, and which value this page uses:
- Ridstar's own copy prints more than one wattage for this bike: 1000W, 2000W Both printed. We state every figure Ridstar publishes and label which sentence each came from, rather than choosing one.
- Ridstar's two storefronts publish different top speeds for this model: ridstar.net says 28 mph; ridstar.com says 34 mph. Both attributed to the storefront that published them.
- Ridstar's page prints more than one motor figure for this bike. Both are in the table above rather than one of them being chosen for you.
- Ridstar's page prints more than one suspension figure for this bike. Both are in the table above rather than one of them being chosen for you.
- Ridstar publishes no figure for charging time, maximum load, bike weight, rider height on this model. Those rows read “not published” rather than being filled in from a sibling model that happens to share the frame.
- The 1040 Wh figure is ours, not Ridstar's: it is the published 52 volts multiplied by the published 20.0 amp-hours. It is the number to compare bikes on, because a bigger amp-hour count at a lower voltage is not more energy.
- Ridstar publishes this bike on its other storefront, ridstar.com, at $1,760.95 for the US variant, read from that storefront's own catalog on 29 August 2026. Prices, and sometimes specifications, differ between the two sites; every figure on this page comes from ridstar.net.
What we counted
We pulled Ridstar's entire live catalog on 2026-08-26 — all 93 published listings — and worked out what is actually on the shelf: 26 bike listings, 11 scooters and 41 accessories. Among the bikes we found 4 pairs of listings that are the same machine listed twice, counted only where the descriptions are byte-identical or the two listings share most of the same image files. The widest gap is the Q30 Pro 4000W, which appears at $899.00 and $1269.00 on the same storefront. That is why the price on this page is matched to a named listing rather than to “the manufacturer”.
Redtail original analysis, counted from Ridstar's public storefront feed and collection endpoints on 2026-08-26; every price cross-checked against a second, independently fetched endpoint. Method: Two listings are called the same bike only where their description text is byte-identical after markup is stripped, or they share 60% or more of the same image FILES. Shared boilerplate paragraphs alone were not enough — an earlier pass that keyed on the first 400 characters produced four false pairs and was discarded.
Where to ride it, and what to check first
The Q20 Pro is a two-wheel-drive machine built for loose ground — trails, private land, sand and snow — and that is where it does its best work.
Ridstar publishes the motor as a combined 2000W and the top speed as 28 mph. Federal law defines the low-speed electric bicycle category this way:
the term “low-speed electric bicycle” means a two- or three-wheeled vehicle with fully operable pedals and an electric motor of less than 750 watts (1 h.p.), whose maximum speed on a paved level surface, when powered solely by such a motor while ridden by an operator who weighs 170 pounds, is less than 20 mph.
15 U.S.C. § 2085(b) (Pub. L. 107–319, § 1, Dec. 4, 2002, 116 Stat. 2776), carried into 16 C.F.R. § 1512.2(a)(2). Retrieved 2026-08-26 from the U.S. Government Publishing Office and confirmed word for word against Cornell's Legal Information Institute.
Set those two published numbers against that threshold and this bike sits outside the federal low-speed electric bicycle definition. What that means where you live is decided by your state: some apply moped, motor-driven cycle or off-highway vehicle rules above the federal line, and those can reach registration, insurance, licensing, helmets and which paths and trails are open to you. Some states set their own wattage ceiling instead. Check yours before you ride on any public road, bike path or trail.
Start here: our state-by-state e-bike law guide. Current as of 2026-08-26; state law changes, so re-check yours before relying on it.
Straight answers on the Q20 Pro
Four things buyers ask before ordering this one, and what each actually means for the ride you are planning.
Ridstar prints two different wattages. Which one am I buying?
Ridstar's page describes the pair as a combined 2000W and separately prints 1000W, and gives no per-motor rating for either motor. The table on this page carries the 2000W combined figure and names the line it came from.
On the trail the number that decides how this bike feels is not the wattage — it is that both wheels drive, which is what gets you out of sand and wet grass. On paper it can matter: several states write their rules around a per-motor rating, and our state-by-state e-bike law guide has the table for yours. If you want a single published motor figure on the sticker, the Q20 1500W publishes one number at $909.
The two Ridstar storefronts publish different top speeds.
ridstar.net publishes 28 mph for the Q20 Pro. ridstar.com publishes 34 mph for the same model.
Every figure on this page is taken from one named listing — ridstar.net, retrieved 26 August 2026 — so the 28 mph in the table is that listing's number, and the other one is recorded rather than quietly dropped. Either way both sit above the 20 mph federal line, so the section above on where to ride it applies whichever figure your bike turns out to match.
Is the 180-mile range claim real?
180 miles is Ridstar's best-case pedal-assist figure, published with no conditions attached, on a 1,040Wh pack that feeds two motors rather than one.
Plan on the pack, not the claim: 1,040Wh is the thing you are actually buying, and on a dual-motor bike you are trading some of it for traction you cannot get any other way. If distance is the priority instead, the Q50 carries 1,200Wh at $799 — more energy, one motor, less money.
Ridstar doesn't publish a weight or a rider height for this one.
Ridstar publishes no bike weight, rider-height range, maximum load or charge time for the Q20 Pro. Those rows read “not published” rather than being filled in from a sibling model that happens to share the frame.
What is published is the part that usually decides the purchase: the 20-inch Q20 platform on 20x4.0 tires, hydraulic dual brakes and dual suspension. If the missing number is the one that decides it for you — rack fit, a garage door, the back of an SUV — ask us before you order and we will answer it before the bike ships.
Frequently asked questions
How fast does the Ridstar Q20 Pro go?
Ridstar.net publishes 28 mph; ridstar.com publishes 34 mph for the same model. Both are manufacturer claims with no test conditions, and the six mile an hour gap between two of the brand's own storefronts is why this page shows you both rather than one.
How many miles can the Ridstar Q20 Pro go?
Ridstar claims 180 miles in pedal-assist mode. That is a best case with no rider weight, assist level or terrain published against it. The pack holds 1,040 watt-hours — our arithmetic from its published 52 volts and 20 amp-hours — which is less than the single-motor Q30 25Ah carries, and this bike has two motors drawing on it.
Is the Ridstar Q20 Pro a 1000W or 2000W bike?
Ridstar's page describes two motors with a combined 2000W output and separately prints 1000W in another line. It publishes no per-motor rating at all. Both figures are in the specification table above; we are not going to choose between them on the manufacturer's behalf.
Is the Ridstar Q20 Pro street legal?
Your state decides, and this is among the least likely bikes in the range to qualify anywhere. Federal law defines a low-speed electric bicycle as a motor under 750 watts with a motor-only top speed under 20 mph; Ridstar publishes this as a dual-motor bike at a combined 2000W and 28 mph, with a second storefront saying 34. Some state statutes turn on the per-motor rating, which is not published. The statute is quoted in full above.
Does the Ridstar Q20 Pro have a throttle?
Yes. Ridstar publishes three riding modes for this bike — pure electric, pedal assist and pedal only — and pure electric mode is the throttle.
How much does the Ridstar Q20 Pro cost?
$1,369 here as of 26 August 2026, matched to Ridstar's own US listing that day. Its other storefront lists the same model at $1,760.95.
What is the difference between the Q20 Pro and the Q30 Pro?
Both are dual-motor bikes on a 52V 20Ah pack (1,040Wh) with hydraulic dual brakes and dual suspension, and both carry a 180-mile assisted claim. The published difference is the wattage figure — Ridstar gives 4000W for the Q30 Pro and a combined 2000W for the Q20 Pro — and the frame each is built on. Neither publishes a per-motor rating.
Ready to ride the Q20 Pro?
Two driven wheels, 52 volts, hydraulic brakes front and rear, and $1,369 with the freight already in it. It ships from us in the lower 48, on our terms, and if a covered part ever fails we file the claim.
