Class 1 and Class 2 electric-assist bicycles can operate on a shared-use path (e.g. sidewalk or bike trail) or any part of a highway designated for the use of bicycles. E-Bikes are classified as follows:
Class 1: The motor provides assistance when a rider is pedaling and stops assisting when the bicycle reaches a speed of 20 mph. Class 2: The motor can propel the bicycle without pedaling but does not assist when the bicycle reaches a speed of 20 mph. Class 3: The motor assists when the rider is pedaling and stops when the bicycle reaches a speed of 28 mph. It also has a speedometer. Riders must be at least 16 years old to operate a Class 3 e-bike (there is no age restriction for slower e-bikes). Class 3 bikes are not permitted on a shared-use path.
