legally\u003c\/h2\u003e\n\u003cp\u003eFederal law defines a low-speed electric bicycle at 15 U.S.C. § 2085(b): a \"low-speed electric bicycle\" is a two- or three-wheeled vehicle with fully operable pedals, a motor of less than 750 watts, and a maximum motor-powered speed on a paved level surface of less than 20 miles per hour when ridden by an operator weighing 170
