Abstract
A two wheeled trailer is used to propel a two wheeled vehicle such as a bicycle or a scooter. The trailer is powered by an electric motor and at least one battery. The control of the motor is through a potentiometer attached to the handlebars of the vehicle and in electrical communication with a controller. The trailer is attached to the vehicle by an attachment arm that is mounted near the rear axle of the vehicle. A coupler that allows three axes of rotation attaches the trailer to the vehicle.
