UL 2849 is the US electrical and fire safety standard for e-bikes. It tests the whole electrical system together: the battery, motor, charger, controller and wiring.
It’s different from UL 2271, which covers only the battery pack. A bike with a UL 2271 battery doesn’t automatically meet UL 2849, because the whole-system test is a higher bar. (UL 2272, which you’ll sometimes see cited, is for hoverboards and e-scooters, not e-bikes.)
UL 2849 covers:
-
E-bikes, including pedal-assist bikes, tested as a complete system: the drive system, battery and charger together.
-
Fire and electric shock risks, including while charging, over the life of the bike.
It doesn’t evaluate how the bike handles or brakes. That’s what test rides and good components are for.
Why it matters in New York
NYC’s Local Law 39 (2023) bans the sale, lease or rental of e-bikes that aren’t certified to UL 2849. So we check every e-bike on our floor for UL 2849 specifically, not just for a UL-certified battery. Questions about a specific bike? Call or text us at 646-736-7716.
