Class 1: pedal-assist only, max 20 mph — allowed on most bike paths. Class 2: pedal-assist plus throttle, max 20 mph — allowed on most roads and some bike paths. Class 3: pedal-assist only, max 28 mph — often restricted from bike paths, may require helmet. Class determines where you can legally ride, so check your local regulations before buying.
