We take accessory development as seriously as bike design. Every Tern accessory prototype undergoes rigorous testing to withstand bumps, scratches, and varying weather conditions. See here how it works.

We prioritize your safety by using batteries and electrical systems that are rigorously tested by third parties. Tern's choice, Bosch’s eBike Battery System, is one of the few systems certified to UL 2849 safety standards.

Tern bikes meant for carrying heavier loads all come with proven structural integrity. Learn about how we put our cargo and passenger-carrying bikes through rigorous testing to ensure they're safe and reliable up to their claimed load limit.
