ABSTRACT:
A power assist apparatus which includes a battery powered motor which is mounted on a manually operated vehicle such as a bicycle, which is to be selectively usable by the rider of the bicycle to not only assist in the manual operation of the bicycle but can be used as a sole source of operation of the bicycle. The power assist apparatus is normally fixedly mounted on the bicycle and is carried with that bicycle at all times. The power assist apparatus includes a housing and exteriorly mounted on that housing is a handle. Movement of the handle to various positions locates the power assist apparatus in either a disengaged position relative to a support wheel of the bicycle or to an engaged position relative to the support wheel of the bicycle. The engaged position actually includes a further engagement position that the handle can be moved to which is to be used when the bicycle is being operated in a wet environment to insure positive frictional engagement between a drive wheel of the power assist apparatus and the support wheel of the bicycle to which it is connected.
