Abstract: This lightweight, compact, two-wheel conversion utility is specifically designed to serve as a dual-purpose device for use with a motorcycle. First, the structural design is such that a removable rail tongue hitch is fitted to the proposed invention allowing the conversion utility to be used as a carrier trailer for the motorcycle until arriving at the desired destination.
