Abstract
A self-propelled trailer may be attached to a bicycle. The speed of the trailer is adjusted based on a signal from a force gauge which indicates whether the bicycle is pulling the trailer or the trailer is pushing the bicycle. In the former situation, the force gauge indicates a tensile load, and in the latter situation, the force gauge indicates a compressive load. Based on the feedback from the force gauge, the speed of the motor attached to the self-propelled trailer is adjusted so that the trailer and bicycle are moving at the same speed or the bicycle is pulling the trailer.
