some moped salesman you are. Here is the actual California law straight from the dmv's website.
406. (a) A "motorized bicycle" or "moped" is any two-wheeled or three-wheeled device having fully operative pedals for propulsion by human power, or having no pedals if powered solely by electrical energy, and an automatic transmission and a motor which produces less than 2 gross brake horsepower and is capable of propelling the device at a maximum speed of not more than 30 miles per hour on level ground.
(b) A "motorized bicycle" is also a device that has fully operative pedals for propulsion by human power and has an electric motor that meets all of the following requirements:
(1) Has a power output of not more than 1,000 watts.
(2) Is incapable of propelling the device at a speed of more than 20 miles per hour on ground level.
(3) Is incapable of further increasing the speed of the device when human power is used to propel the motorized bicycle faster than 20 miles per hour.
(4) Every manufacturer of motorized bicycles, as defined in this subdivision, shall provide a disclosure to buyers that advises buyers that their existing insurance policies may not provide coverage for these bicycles and that they should contact their insurance company or insurance agent to determine if coverage is provided.
(c) The disclosure required under paragraph (4) of subdivision (b) shall meet both of the following requirements:
(1) The disclosure shall be printed in not less than 14-point boldface type on a single sheet of paper that contains no information other than the disclosure.
