Two motors and a 52-volt pack. The Q30 Pro is the fastest-accelerating thing Ridstar puts a fat tire on.
The highest power figure Ridstar publishes for anything, on the only other 52-volt platform in the range.
Quick answerThe Q30 Pro is the top of Ridstar's Q30 line at $1,269: two motors published at a combined 4000W, two 52V 20Ah packs (2,080Wh combined), hydraulic dual brakes and dual suspension on 20x4.0 tires.

The maker's safety record, before you buyThe Q30 Pro Dual-Motor Fat Tire Electric Bike is named in no regulator's notice as of September 11, 2026. It was built by the company that is. Everything below is quoted from the regulators and the courts, and it is on this page because a buyer choosing this bike deserves to know who made it and how that company answered a federal safety agency.
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."
The June 25, 2026 warning covers the "Ridstar Q20 and Q20 Lite e-bikes": "The front wheel can detach without warning, posing a crash hazard to consumers." The Commission "is aware of 32 reports of the front wheel detaching, including 31 reports of injuries such as concussions, broken bones, cuts, scrapes, and bruises." Its instruction: "stop using the e-bikes immediately and dispose of them. Do not sell or give away these hazardous e-bikes."
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.
The same company also sells the YVY brand. The full record, the Trustpilot scores, the warranty terms and every model's status are in our Ridstar brand profile, verified September 11, 2026.

Why this bike
Two-wheel driveMotors front and rear, and the biggest number Ridstar prints
A single-motor fat bike puts everything through the back wheel, and on gravel, wet grass or a sand track that wheel spins while the front one just steers. Drive both and the bike hooks up and goes. Ridstar publishes brushless motors at each end totalling 4000W here — the largest figure it prints against any bike it makes.
Price positionThe cheaper of the two 52-volt bikes we stock
At $1,269 this undercuts the Q20 Pro by $100 while carrying the same twin 52V 20Ah packs and the higher published power figure. If you were choosing between our two dual-motor bikes on paper alone, this is the one that costs less and claims more.
Stopping and staying plantedHydraulic brakes and suspension, front and rear
Speed is only worth buying if the bike is specified to lose it again. Hydraulic brakes need less hand pressure for the same bite and hold it when the levers are soaked, which matters on a heavy bike carrying pace down a rough descent. Suspension at both ends keeps the tires on the ground rather than skipping across ruts — no other Ridstar publishes a more complete component list.
Against the Q20 ProWhat actually separates our two dual-motor bikes
They share the twin 52V 20Ah packs, the 2,080 watt-hours they hold, hydraulic dual brakes, suspension at both ends, 20x4.0 tires and a 7-speed drivetrain. Two things differ: the power figure Ridstar prints, 4000W here against a combined 2000W there, and the frame family — Q30 rather than Q20. On price this one sits $100 below.
Why buy the Q30 Pro here
$1,269, and the freight is in it. That is $100 less than the 52-volt Q20 Pro on the same dual-motor platform, and the highest published power figure in our Ridstar range. Free shipping in the lower 48, and Shop Pay instalments at checkout.
Free US shipping
Your Q30 Pro ships free anywhere in the lower 48, with tracking emailed the day it leaves. Nothing is added at checkout: the $1,269 on this page is the $1,269 you pay.
Pay over time
Shop Pay instalments are live at our checkout, so you can split the $1,269 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 Q30 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®-q30pro-4000w-fat-tire-ebike-2, 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 Q30 Pro the right one for you?
Buy it if
- You want the largest power figure Ridstar publishes, driving both wheels, on ground that justifies it
- You want a 52-volt pack rather than a 48-volt one, and you want it at the lower of our two prices for that platform
- You want hydraulic brakes and suspension at both ends on a bike that will actually use them
- You are choosing between our two dual-motor bikes and want the one that costs $100 less
Or one of these instead
- Prefer the Q20 frame, or want the more conservative published power figure? The Q20 Pro is the same 52-volt dual-motor platform at $1,369.
- Chasing distance rather than acceleration? The Q50 holds 1,200 watt-hours on a 48V 25Ah pack, for $799.
- Same Q30 frame, single motor, half the outlay? The Q30 Lite runs 1500W on a 48V 15.6Ah pack at $899.

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.

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.

Specifications as published by Ridstar at ridstar.net/products/ridstar®-q30pro-4000w-fat-tire-ebike-2, 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 2000W 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: 2000W, 4000W Both printed. We state every figure Ridstar publishes and label which sentence each came from, rather than choosing one.
- 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 2080 Wh figure is ours, not Ridstar's: it is the published 52 volts multiplied by the published 20.0 amp-hours, then doubled for the second pack Ridstar publishes on this bike. It is the number to compare bikes on, because a bigger amp-hour count at a lower voltage is not more energy.
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 Q30 Pro is a two-wheel-drive machine built for loose ground — trails, private land, sand and snow — and that is where its power is worth having.
Ridstar publishes the motor as a combined 4000W 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 Q30 Pro
Four things buyers ask before ordering this one, and what each actually means for the ride you are planning.
Ridstar prints two different power figures. Which one am I buying?
Ridstar's own page for this bike carries 4000W in its title and describes two motors totalling 2000W in its copy, and publishes no per-motor rating. The table on this page carries the 4000W nameplate figure and records the other.
The hardware is the same either way you read it: two brushless motors, one at each wheel, pulling from a 52-volt pack. That is what you feel when you open the throttle on a loose climb. The figure earns its importance on paper, where a handful of states write their rules around a per-motor rating — our state-by-state e-bike law guide carries the table. Want a single number and nothing to reconcile? The Q30 Lite publishes 1500W, at $899.
Ridstar lists this same bike a second time, at $899.
We pulled Ridstar's whole catalog on 26 August 2026 and found the Q30 Pro published twice, with byte-identical descriptions and the same photographs, at $899 and $1,269. Our $1,269 matches the listing Ridstar merchandises in its own bike collections.
Here is what the difference buys: freight included both ways in rather than $200 back if you cancel after despatch, a US company that files the warranty claim instead of you emailing a factory, our return terms rather than Ridstar's, and Shop Pay instalments at checkout. If the budget is the deciding factor rather than the second motor, the Q30 Lite is $899 here, ships free, and is a bike we can put on a truck today.
Is the 180-mile range claim real?
180 miles is Ridstar's best-case pedal-assist figure for this bike, published with no rider weight, assist level or terrain attached, on 2,080Wh of pack feeding two motors.
Buy the pack, not the headline: 2,080 watt-hours is the fuel tank, and two motors will empty it faster than one in exchange for grip you cannot get any other way. Want the miles instead? The Q50 holds 1,200 watt-hours for $799.
Ridstar doesn't publish a weight, a load rating or a rider height for this one.
Ridstar leaves four rows blank for the Q30 Pro: charging time, maximum load, bike weight and rider height. Blank is what they stay — no figure is carried across from a Q30 that happens to share the frame.
The figures that decide most of these purchases are published: the Q30 frame on 20x4.0 tires, hydraulic brakes front and rear, suspension front and rear. If the missing one is what settles it for you — whether it clears a garage door, fits a hitch rack, goes in the back of an SUV — send us the measurement and you will have an answer before you order.
Frequently asked questions
How fast does the Ridstar Q30 Pro go?
Ridstar publishes 28 mph for the Q30 Pro. That is a manufacturer claim on throttle with no test conditions published against it, and it puts the bike above the 20 mph federal low-speed line — see where to ride it, above.
Is the Ridstar Q30 Pro 2000W, 3000W or 4000W?
Ridstar publishes 4000W in the product title and describes two motors totalling 2000W in the body copy. The specification table on this page carries 4000W, the nameplate figure, and the 2000W is recorded beneath it. No per-motor rating is published for either motor.
How many miles can the Ridstar Q30 Pro go?
Ridstar claims 180 miles in pedal assist, with no rider weight, assist level or terrain attached. The number to plan around is the 2,080 watt-hours the two packs hold — 52 volts times 20 amp-hours each, both published. If distance is your priority, the Q50 holds 1,200 watt-hours.
Is the Ridstar Q30 Pro street legal?
Your state decides. Federal law defines a low-speed electric bicycle as having a motor under 750 watts and a motor-only top speed under 20 mph, and Ridstar publishes this bike at 28 mph with a 4000W nameplate, so it sits outside that definition. Some states write their rules around a per-motor rating, which Ridstar does not publish. The statute is quoted in full above, and our state-by-state guide has the detail for yours.
How much does the Ridstar Q30 Pro cost?
$1,269, with free shipping anywhere in the lower 48 and Shop Pay instalments available at checkout. That is $100 below the Q20 Pro, the other 52-volt dual-motor bike we stock. Ridstar also publishes this same bike on a second listing of its own at $899 — what the difference buys you is set out under Straight answers, above.
Does the Q30 Pro have dual suspension?
Yes — Ridstar publishes suspension at the front and the rear, together with hydraulic dual brakes. That pairing is the most complete component specification Ridstar lists for any bike in the range.
What is the difference between the Q30 Pro and the Q20 Pro?
On paper, two things. Ridstar prints 4000W for the Q30 Pro and a combined 2000W for the Q20 Pro, and each sits on its own frame family. Everything else matches: twin 52V 20Ah packs, 2,080 watt-hours, hydraulic dual brakes, suspension both ends, 20x4.0 tires, 7-speed. The Q30 Pro is the cheaper of the two here, at $1,269 against $1,369.
Ready to ride the Q30 Pro?
The largest power figure Ridstar prints, both wheels driven, 52 volts, and $1,269 with the freight already paid. Order it and it leaves our dock for the lower 48, backed by a warranty we handle on your behalf.
