An assisting apparatus for using power from a rotating member to assist the operation of a bicycle transmission includes a mounting unit and an input transmission member coupled to the mounting unit, wherein the input transmission member moves to at least a first input position, a second input position and a third input position. An output transmission member is coupled to the mounting unit, wherein the output transmission member moves to at least a first output position, a second output position, and a third output position corresponding to the first input position, the second input position and the third input position of the input transmission member, respectively. A rotating member engaging member moves between a rotating member engaging position and a rotating member disengaging position, and a motion transmitting mechanism is provided for transmitting motion from the rotating member engaging member to the output transmission member.
