One embodiment of an assisting apparatus 14 for using power from a rotating member 534 to assist the operation of a bicycle transmission includes a mounting unit and an input transmission member 176 coupled to the mounting unit, wherein the input transmission member 176 moves to at least a first input position, a second input position and a third input position. An output transmission member 280 is coupled to the mounting unit, wherein the output transmission member 280 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 280. A switching mechanism is provided for moving the rotating member engaging member to the rotating member engaging position when the input transmission member 176 is in one of the first input position, second input position or third input position and the output transmission member 280 is not in the corresponding first output position, second output position, or third output position, and for moving the rotating member engaging member to the rotating member disengaging position when the input transmission member 176 is in one of the first input position, second input position or third input position and the output transmission member 280 is in the corresponding first output position, second output position, or third output position. <IMAGE> |
