Ask any bike shop owner if they fix electric bikes, and you'll get an interesting array of stories. MacKenzie Hardt from Aurora, Colorado, has learned the hard way: he knows a guy who lost a finger working on ebikes, and he himself tore his tendons after accidentally triggering a cadence sensor on a stand.

The problem isn't just about parts or safety; it's also about regulation. An electric vehicle sold as an ebike might not actually be one, leading to confusion over what qualifies. In 46 states, ebikes are classified into three categories based on speed and power, but many online models exceed the Class 3 limit of 28 mph.

Repairing such bikes can also land a shop in a quagmire of liability issues. Bike shops, part of the product liability chain, might find themselves responsible for injuries if they even inflate a tire on an electric vehicle. Hospital data shows ebike-related injuries have jumped more than 1,020 percent from 2020 to 2024.

With no national standard and many states following PeopleForBikes' Model Legislation, the industry struggles to coalesce around a universal definition of an ebike. As Matt Moore points out, the US bicycle industry has sold durable products designed for repair, but during the pandemic, demand surged, leading to online purchases with specialized or proprietary parts that are hard to find.

The good news is that reputable companies like Liv Cycling offer UL-certified batteries and motors, ensuring a smooth repair process. However, this often means dealing with authorized shops rather than the convenience of an online purchase. For now, it seems fixing an ebike remains more of a challenge than a routine service call.
