The U.S. NHTSA Code of Motor Vehicle Safety simply defines low-speed electric bicycles as consumer products and not Motor Vehicles for safety standards. In doing so they vest authority over commercial safety standards to the Consumer Product Safety Commission.
The Consumer Product Safety Commission(CPSC) stipulates
that commercially manufactured low-speed electric
bicycles, or tricycles, must have fully operable pedals,
an electric motor of less than 750W of power and a top
motor-powered speed not in excess of 20 miles per hour
An electric bike remaining within these specifications
will be regarded simply as a bicycle for purposes of
safety standards. This supersedes any state law that is
more stringent, but only regarding safety equipment
required on electric bicycles and the standard of
manufacture they must meet.. The
legislation enacting this amendment to the CPSC is also
known as HR 727.
IA problem with the motorcycle is that there is no
provision for pedal power because the vehicle weight is
much to high. So for a vehicle to have a motor and
pedal power it needs to be as light as possible.
That's especially important if climbing hills is involved
and not so important on flat ground. See:
