The U.S. Consumer Product Safety Commission issued a June 25, 2026 product safety warning telling riders to stop using Ridstar Q20 and Q20 Lite e-bikes immediately because the front wheel can detach without warning.
This is a serious safety notice for anyone who bought one of the black fat-tire Ridstar models through large online marketplaces. CPSC says it knows of 32 reports of front-wheel detachment, including 31 injury reports involving concussions, broken bones, cuts, scrapes, and bruises.
What CPSC Says Is Wrong
The warning covers Ridstar Q20 and Q20 Lite e-bikes. CPSC says the brand name Ridstar appears on the battery, while the model number Q20 or Q20 Lite appears on the purchase receipt.
The agency says riders should stop using the e-bikes immediately, dispose of them, and not sell or give them away. For the Ridstar Q20, CPSC adds that the battery was also part of an earlier product safety warning and must be disposed of through local hazardous waste procedures.
CPSC says the manufacturer, Huizhou Xingqishi Sporting Goods Co., Ltd. of China, has been unresponsive to agency requests for information about the products or a recall. That means this notice does not list a repair, refund, or replacement program.
Where The Bikes Were Sold
CPSC says the e-bikes were sold on AliExpress.us, Amazon.com, Ridstar.net, and Walmart.com. The agency lists the manufacturer as China-based Huizhou Xingqishi Sporting Goods Co., Ltd.
If you bought a Ridstar fat-tire e-bike secondhand, check your receipt, battery marking, and order history before riding again. The public warning names the Q20 and Q20 Lite models, and CPSC says the risk comes from the front wheel detaching without warning.
What Riders Should Do
Do not keep riding the bike while you look for parts or a home fix. A front wheel failure can turn a low-speed ride into a crash before the rider has time to react.
Owners should follow the CPSC stop-use instruction, check local rules for e-bike and lithium-ion battery disposal, and avoid reselling the bike. If the bike is stored at home, treat the battery separately from the frame when planning disposal.
This warning also gives shoppers a reason to be stricter with low-cost marketplace e-bikes. Price matters, but so do product support, parts traceability, and whether the seller responds when a federal safety agency asks for recall information.

What Is Confirmed
CPSC confirms the June 25, 2026 warning date, the affected Ridstar Q20 and Q20 Lite model names, the reported front-wheel detachment hazard, 32 detachment reports, 31 injury reports, the listed sales channels, and the agency’s stop-use and disposal advice.
What is not confirmed from the CPSC warning is how many affected bikes remain in use, whether any seller will later offer a remedy, or whether all online product pages have been removed. Riders should rely on their own purchase records and the official CPSC notice, not marketplace listing status.
