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. There, the rail tongue hitch is detached from the frame, the motorcycle is backed between the two wheels of the utility, and is quickly and easily mounted to the rear axle and frame, thus converting the carrier trailer to a stabilizer for the motorcycle giving it a three wheel appearance. This makes it capable of increasing load capacity and less likely to overturn. The wheels are located on the outside of the conversion utility's frame and are laterally spaced apart on opposite sides of the rear wheel of the motorcycle.

Abstract: A tandem adapter frame that attaches to the back of a single-rider bicycle, transforming the bicycle into a tandem bicycle.

This transforms the single-rider bicycle into a rigid frame, two wheel, tandem bicycle with a rider in front and a rider in back. Both riders have pedals. An adapter axle assembly with sprockets on the lower front of the adapter frame serves two functions. It easily attaches between the rear dropouts of the single-rider bicycle using a standard axle and quick-release, and it transmits drive power to the rear crank without modifying the drive chain of the single-rider bicycle.
