The statute also states that "Motorized bicycles such as pocket bikes and scooters that do not meet the requirements of this policy shall not be registered." As R.S. 32:1(41) refers to motorized bicycles using "an automatic transmission" with helper motors rated in horsepower and cylinder capacity, not by watts or volts, the statute arguably does not cover bicycles powered by an electric motor(s), whether self-propelled or pedal-assist designs. Maryland defines an "electric bicycle" as a vehicle that (1) is designed to be operated by human power with the assistance of an electric motor, (2) is equipped with fully operable pedals, (3) has two or three wheels, (4) has a motor with a rating of 500 watts or less, (5) and is capable of a maximum speed of 20 miles per hour on a level surface when powered by the motor. (Senate Bill 379, approved by the Governor 5/5/2014, Chapter 294.) This legislation excludes "electric bicycle" from the definition of "moped", "motorized minibike", and "motor vehicle", and removes the titling and insurance requirements required for electric bicycles under prior Maryland law. Before September 20, 2014, Maryland law had classified an electric bicycle as a moped. Mopeds are specifically excluded from the definition of "motor vehicle" per § 11-135 of the Maryland Transportation Code. Mopeds may not be operated sidewalks, trails, roadways with posted speeds in excess of 50 mph, or limited-access highways. Standard requirements for bicycle lighting, acceptable bicycle parking locations, and prohibitions on wearing earplugs or headsets over both ears apply. Recent legislation has passed putting Maryland ebike laws in line with the popular class 1,2,3 systems previously implemented in states such as California. This legislation becomes effective October 2019. The most significant portion of this change is the increased max limit on power and speed. It will be increased from a max of 500w / 20 mph to 750w / 28 mph (assuming the ebike in question meets class 3 criteria)  Massachusetts General Laws define three classes of motorized two-wheeled vehicles: "Motorcycle", "Motorized bicycle", and "Motorized scooter". Although the definition of "motorized scooter" includes two-wheeled vehicles propelled by electric motors with or without human power, motorized scooter specifically excludes anything which falls under the definitions of motorized bicycle and motorcycle.
