E-bike class explained
- Class 1: you must pedal for motor assistance; assistance stops at 20 mph.
- Class 2: a throttle can power the bike without pedaling; motor assistance stops at 20 mph.
- Class 3: pedal-assisted riding, with motor assistance stopping at 28 mph.
Classes 1 and 2 share a 20 mph assistance limit. The key difference is whether the motor can propel you without pedaling.
Use the bike’s label and current configuration, not its appearance. Motorcycles and e-motos are not Class 1–3 e-bikes. A class label or “Street” selection does not establish legal road or trail use; modifications can change classification.
