E-bike classes usually describe how assistance works and the speed at which it stops. Trail, road and access rules vary by jurisdiction, so a class label is the beginning of your homework—not the end.
Class 1: pedal-assist only
A common U.S. three-class framework treats Class 1 as pedal-assist only, with assistance cutting off at 20 mph. This is a description of a legal framework, not permission to ride any given trail.
Class 2: a throttle enters the picture
Class 2 commonly allows motor assistance by a throttle up to 20 mph. Some bikes can be configured into multiple classes; always confirm how the bike actually ships and the rules where you ride.
Class 3: higher pedal-assist cutoff
Class 3 commonly offers pedal-assist up to 28 mph. States and cities can set separate helmet, age, trail and access requirements.
What to check before checkout
Check the current manufacturer configuration, local law, trail authority guidance, brake and tire suitability, and whether changing settings would alter its legal classification.
