Low-speed electric bicycle
What does Low-speed electric bicycle mean?
The US federal product definition of an e-bike: working pedals, a motor under 750 W, and under 20 mph on motor power alone.
A low-speed electric bicycle is the US federal term for an e-bike in consumer product law. 15 U.S.C. 2085 defines it as a two- or three-wheeled vehicle with fully operable pedals and a motor of less than 750 W (1 hp), with a top speed under 20 mph on motor power alone, measured with a 170 lb rider on a paved, level surface.
How does it relate to the three classes?
The federal definition covers product safety. Where and how you can ride is set by state law, which usually uses Class 1, 2 and 3. A Class 3 e-bike adds pedal assistance up to 28 mph.
