1,200 watt-hours on the Q30 frame. The pack is the whole upgrade.
The long-range Q30: same frame, same motor, a quarter more battery than the 20Ah beside it.
Quick answerThe Q30 25Ah is the long-range Q30 at $849: 2000W, a 48V 25Ah pack holding 1,200 watt-hours, hydraulic dual brakes, a front fork, seven speeds and a 330 lb rating, published at 33 mph. It is out of stock with us today; the Q50 matches it at $799.
Out of stock right now. The Q50 is in stock at $799 and carries the identical published pairing: 2000W, a 48V 25Ah pack holding 1,200 watt-hours, hydraulic dual brakes and a 330 lb rating, at $50 less. See the Q50.
The Q30 2000W 48V 25Ah 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
The upgrade1,200 watt-hours, a quarter more than the 20Ah
Ridstar's 48 volts times its 25 amp-hours. Against the 960 watt-hour version of the same bike that is a quarter more energy for a small price step, and it is the only specification that separates the two on Ridstar's own numbers.
BrakesHydraulic dual brakes
Published at both ends, and the appropriate specification on the family Ridstar rates highest for speed. Less hand pressure for the same bite, and consistent when wet.
Rated330 lb, seven speeds, four to six hours
The load ceiling covers rider and cargo together, the gears keep you useful with the assist off, and the charge window is short enough to turn the bike round in an afternoon despite the bigger pack.
ForkFront suspension, published
Ridstar specifies a fork at the front and states nothing at the rear for the Q30 family. A simpler frame with one less pivot, and the fork takes what the fat tires do not.
Why buy the Q30 25Ah here
The Q30 25Ah is $849 when it is here. Today the Q50 carries the same 2000W rating, the same 1,200 watt-hours and the same hydraulic brakes for $799. Free freight in the lower 48 covers both, and Shop Pay instalments are there at checkout.
Free US shipping
Your Q30 25Ah ships free anywhere in the lower 48, with tracking emailed the day it leaves. Nothing is added at checkout: the $849 on this page is the $849 you pay.
Pay over time
Shop Pay instalments are live at our checkout, so you can split the $849 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 25Ah 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®-q30-2000w-48v25ah-wide-tire-electric-bicycle, 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.

The first 48 hours
Open the box and look it over on the day it lands. Report damage or a wrong item with photos inside 48 hours and it becomes our problem to solve. You send the photos; we handle the rest.
Bikes with power, charging, or component issues are covered under the manufacturer warranty; Redtail coordinates repair or replacement remotely at no cost to the customer.
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.

Specifications as published by Ridstar at ridstar.net/products/ridstar®-q30-2000w-48v25ah-wide-tire-electric-bicycle, 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 50-70 miles for the range; Ridstar also prints 5-6 hours for the charge window; Ridstar prints “hydraulic dual brakes”, “disc brakes” and “disc brake” across its copy for this model.
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 page prints more than one range 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 charging time 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 brakes figure for this bike. Both are in the table above rather than one of them being chosen for you.
- Ridstar publishes no figure for 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 1200 Wh figure is ours, not Ridstar's: it is the published 48 volts multiplied by the published 25.0 amp-hours. It is the number to compare bikes on, because a bigger amp-hour count at a lower voltage is not more energy.
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 25Ah is a 20-inch fat bike for trails, tracks and private land, and Ridstar publishes 33 mph for it, the highest figure in this range.
Ridstar publishes the motor as 2000W and the top speed as 33 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 25Ah
Four things buyers ask before ordering this one, and what each actually means for the ride you are planning.
33 mph sits a long way outside the federal definition.
Ridstar publishes 33 mph for the Q30 family, 13 mph above the 20 mph federal low-speed threshold, and it is the highest published speed of anything in this range.
Ride it where a 2000W fat bike belongs: private land, trails and tracks. Before any public road or path, check your state, because a speed claim is what many statutes turn on; our state-by-state e-bike law guide carries the table. If a lower published figure suits you better, the Q30 Lite is published at 28 mph and is in stock.
Is the extra battery worth it over the 20Ah?
The two bikes differ in one published specification: 1,200 watt-hours against 960. Motor, brakes, frame, gearing and load rating are identical on Ridstar's numbers.
If your rides regularly run past what 960 watt-hours covers, the extra quarter is the cheapest range you will buy anywhere in this family. If they do not, spend less. Either way the Q50 publishes the same 1,200 watt-hours at $799 and is the one on the shelf today.
Two range figures and two charge times on one page.
Ridstar publishes 55 miles and 50 to 70 miles, and four to six and five to six hours. This page uses 55 miles and the four-to-six-hour window.
Both spreads are narrow enough to be planning noise. The figure to reason from is the 1,200 watt-hours, which comes from published volts and amp-hours rather than from copy.
Can I order it today?
Not right now; it is away from our store, and the page stays up so the specification and its sources stay readable.
Message us and we will let you know the day it is back. On Ridstar's own published figures the Q50 is the same motor, the same pack and the same brakes for $50 less, and it ships free today.
Frequently asked questions
How fast does the Ridstar Q30 25Ah go?
Ridstar publishes 33 mph, the highest figure in this range and 13 mph above the federal low-speed line. That is a throttle figure from the manufacturer, published without test conditions.
What is the difference between the Q30 20Ah and 25Ah?
One published specification: 1,200 watt-hours against 960. Same motor, same hydraulic brakes, same frame, same gearing, same 330 lb rating. Neither is in stock today; the Q50 publishes the same 1,200 watt-hours at $799.
How far will it go on one charge?
Two figures appear on the page, 55 miles and 50 to 70; this one uses 55. The pack holds 1,200 watt-hours, 48 volts times 25 amp-hours.
Is the Ridstar Q30 street legal?
Your state decides, and this family sits furthest from the federal definition of anything we list. Federal law defines a low-speed electric bicycle as having a motor under 750 watts and a motor-only top speed under 20 mph; Ridstar publishes 2000W and 33 mph here. The statute is quoted in full above.
How much is the Ridstar Q30?
$849 for the 25Ah version here when it is in stock. The Q50 publishes the same motor, pack and brakes at $799 and is available today, with free shipping in the lower 48.
How heavy is the Ridstar Q30?
Ridstar publishes no weight for this model. That 330 lb number is the ceiling for rider plus cargo, not the bike's own weight.
Does the Ridstar Q30 have rear suspension?
No. Ridstar publishes a front suspension fork for the Q30 family and states nothing at the rear.
Ready to ride?
The Q30 25Ah is out of stock today. The Q50 matches this bike's published motor, pack and brakes, costs $50 less, and ships today.
