Abstract
A single wheeled trailer for carrying an occupant is provided. The frame of the trailer is comprised of tow bar members of rectangular cross section and two non-symmetrical rear fork members which retain the single wheel. A hitch connected to a driving bicycle tows the trailer. A pedal assembly coupled to the frame enables the occupant to power the trailer wheel. The occupant of the trailer is forward facing and may help power the bicycle or be towed by the prime mover. The frame design allows ease of mounting and dismounting of the child.
