Abstract
A bicycle may tow a trailer for the purposes of carrying a heavy or large object across great distances. A motor may be mounted to the trailer which drives a rear wheel of the bicycle. To this end, a transmission is added to the rear hub of the bicycle which is mechanically coupled to the output shaft of the motor. When the trailer is detached or not used in conjunction with the bicycle, the rider does not have to carry the weight of the motor. Also, this setup provides a stable configuration since the bicycle is pulling the trailer.
