Amazon and safety-certification firm UL have settled a lawsuit against several Chinese manufacturers accused of falsely claiming their Aipas-branded ebikes carried UL safety certification. A federal judge signed a permanent injunction on 15 July barring the firms from using the UL mark or helping others do so, though the companies admitted no wrongdoing. Wired found the ban is already being flouted, with adverts still running that display UL's logo, underscoring a wider problem of fraudulent safety marks on ebikes and their batteries sold through online marketplaces.

Wired identified a Facebook account tied to Aipas Ebike still serving adverts bearing UL's logo, including one shown to a reporter in mid-July after the injunction took effect, and another that had been running since April. UL said it was "aware and working to resolve" the issue, while Amazon and Aipas declined to comment. The stakes are significant: a US government report found 45 deaths linked to lithium-ion battery fires in mobility devices between 2017 and 2024, 19 of them involving ebikes, while New York City recorded 277 such fires in 2024, up from 268 the year before. Experts say fake certifications are especially common on marketplaces like Amazon, where consumers face a heightened risk of buying counterfeit or falsely certified products.
