They're Fun to Ride, but are They Legal?

From the Baltimore County, MD. Police Department

Baltimore County, Md. (December 5, 2005) - Motorized scooters, mini scooters, "pocket rockets," and similar devices have grown in popularity and have generated a number of questions among consumers and community groups.  In response, the Baltimore County Police Department offers these guidelines on owning and operating equipment.

Motorized Scooter

Motorized scooter: A two-wheeled device with handlebars that is designed to be stood on by the operator and is powered by an electric or gas motor. 

Motor Scooter

Motor scooter: Has a seat for the operator, and two wheels, one of which is 10" in diameter or more and has a step-through chassis.  It has a motor with a rating of 2.7 brake horsepower or less, or a motor with a capacity of 50cc displacement or less and is equipped with an automatic transmission.

Moped

Moped: A bicycle designed to be operated with the assistance of a motor and is equipped with pedals that mechanically drive the rear wheels. It has two or three wheels, one of which is more than 14" in diameter, and has a motor with a rating of 1.5 horsepower or less, and an internal combustion engine of 50cc piston displacement or less.

Pocket Rockets, Mini-Cycles or Mini-Harleys

Vehicles popularly known as pocket rockets, mini-cycles, or mini-Harleys, do not have the characteristics of the devices listed above. For example, unlike motorized scooters, they have seats, and they do not have the step-through chassis of a moped. In addition, under state law, these vehicles do not fit the description of a motor vehicle, and they cannot be registered and insured.
