In Pennsylvania, both types are considered "pedal cycles with electric assist" as long as they meet certain criteria: a motor under 750 watts, a maximum speed of 20 mph on a level surface when using the motor only, and operable pedals. Electric-assist bicycles (e-bikes) are generally treated like traditional bicycles under PA state law. E-bike riders are expected to operate their bikes safely and responsibly.
