Abstract
A one wheel trailer for a two-wheeled vehicle such as a motorcycle, or the like, is disclosed. The trailer includes a first and a second arm, each arm having a first and a second end. The first end of each arm is connected preferably to the site corresponding to a passenger footpeg of the two wheeled vehicle or the like. A rigid frame is secured adjacent the second end of each arm. A container is secured to the bulkhead and a spring biased suspension arm is pivotally connected to the bulkhead. A castor arm is mounted adjacent the distal end of the suspension arm enabling swivelling of the castor arm relative to the suspension arm. A wheel is rotatably mounted relative to the castor arm permitting the wheel to support the container.
