Abstract: The present invention provides a propulsion assembly for a bicycle. The propulsion assembly includes a support member that at least extends from the bicycle frame to a distal end spaced-apart from the rear wheel. The assembly includes a first drive mechanism rotatably mounted on the frame and axially connected to the rear wheel for transmitting motion thereto. A second drive mechanism is rotatably mounted at the distal end of the support member and coupled with the first drive mechanism. Ratchet mechanisms axially extend from the second drive mechanism and connect to a pair of elongate members having pedals. The pedals are movable from an upper position to a lower position for transmitting one-way rotational power to the second drive mechanism. There is a means for selectively returning the pair of elongate members from the lower position to the upper position.
