Thousands of electric bikes are being recalled over concerns their lithium-ion batteries can explode and burn consumers, the U.S. Consumer Product Safety Commission announced Thursday.

Manufacturer Ancheer said should stop using the batteries on e-bike model number AM001907, of which there are roughly 22,000 units, per the CPSC.

The CPSC said the bikes were sold on the following websites from January 2016 to June 2022: Amazon, Walmart, eBay, Sears, Wish, Rakuten, Overstock, Aliexpress, Ancheer, and Newegg. The bikes were priced between $280 and $930, according to the CPSC.

The company, which said it issued the recall voluntarily, "has received six reports of incidents involving fire, explosions, or sparks, including four reports of burn injuries," according to the CPSC's news release.

The affected model number can only be found on the product's packaging, and not on the bike itself, Ancheer said.

Alternatively, Ancheer said customers can mail the recalled batteries to them by requesting a pre-paid mailing package and shipping label at the same email. The manufacturer said it can be reached at 888-661-1330 for additional information.
