Abstract
A one wheeled trailer is disclosed for use with and for pulling behind a two wheeled vehicle such as a motorcycle or motorbike. The trailer is configured to track behind the motorcycle or motorbike and to lean with the cycle as a unit so as to respond in the same manner as the motorcycle or motorbike. The trailer is supported on a single tire aligned to track behind the motorcycle tires thereby eliminating the sideways torque when the trailer hits a pothole or a curb. The trailer is designed to perform on the road and in turns the same as the motorcycle and does not limit the motorcycle from performing the way it was intended.
