IN BRIEF
A Florida resident, Therese Evans, is suing Walmart on behalf of a minor injured on 1 November 2025 while riding a Ridstar electric bike bought from the retailer. According to Bicycle Retailer, which has read the complaint, the machine « suddenly and catastrophically failed when the front wheel unexpectedly detached », causing « serious and permanent injuries ». The complaint was filed on 30 July with the Palm Beach County court before being transferred to the federal court for the Southern District of Florida. The connection is hard to ignore: in June 2026, more than seven months after the crash, the federal product safety agency, the CPSC, told owners of the Ridstar Q20 and Q20 Lite to stop using them immediately, citing 32 reports of the front wheel detaching.
In that case, the manufacturer did not respond: the CPSC writes that it « has been unresponsive » to its requests. The Ridstar Walmart lawsuit filed in Florida, for its part, targets the retailer that sold the bike.
A Ridstar Walmart lawsuit aimed at the retailer
Bicycle Retailer reported on 28 August the filing of an action brought by Therese Evans against Walmart Inc., on behalf of a minor identified by their initials. According to the complaint, as reported by Bicycle Retailer, the young rider was riding on 1 November 2025 « in a reasonably foreseeable manner » when the bike « suddenly and catastrophically failed when the front wheel unexpectedly detached ». The complaint refers to « serious and permanent injuries ».
The central argument turns on what the seller knew. Still according to Bicycle Retailer, the complaint contends that Walmart « knew or should have known of complaints, customer reports, warranty claims, product failures and other information » pointing to a risk. In other words, the complaint argues that a retailer putting a product on its website could not hide behind the identity of the manufacturer once the reports pile up.
As of the publication date of the Bicycle Retailer article, no response from Walmart appeared in it. The proceedings, meanwhile, have changed jurisdiction: « the complaint was originally filed on 30 July in Palm Beach County circuit court, but the case was moved to federal court in the Southern District of Florida ».
According to Bicycle Retailer, medical costs exceeding $120,000 were submitted on 14 August, and Therese Evans is seeking damages in excess of $50,000, plus costs, interest and a jury trial. The outlet notes, however, that the complaint « does not specify a total damages amount ».
What the CPSC had already written about the Ridstar Q20
The background is documented by the federal agency itself. In a public warning, the CPSC « warns consumers to immediately stop using Ridstar Q20 and Q20 Lite electric bicycles because they pose a risk of serious injury and death ». The defect is named bluntly: « the front wheel can detach without warning, posing a crash hazard to consumers ».
The scale is quantified: the agency « is aware of 32 reports of the front wheel detaching, including 31 reports of injuries such as concussions, fractures, cuts, abrasions and contusions ». It asks people not to pass the problem on to someone else: « do not sell or give away these dangerous e-bikes ». The Q20 batteries, it points out, had already been the subject of an earlier warning and must go through hazardous waste disposal.
A manufacturer that does not answer, four sales channels
According to the CPSC, « the manufacturer, Huizhou Xingqishi Sporting Goods Co., Ltd., of China, has been unresponsive to CPSC’s requests for information about these products or a recall ». With no counterpart to talk to, there is no organised recall: the agency is left publishing a warning and counting the reports.
The warning also lists the points of sale: « the e-bikes were sold on AliExpress.us, Amazon.com, Ridstar.net and Walmart.com ».
To help identify the machines concerned, the CPSC gives physical markers: « the e-bikes are black and the brand name Ridstar is printed on the battery. The model number Q20 or Q20 Lite is printed on the purchase receipt. » A telling detail about this market: you have to dig out your receipt to know which model you are sitting on.
