    • An assisting apparatus for using power from a rotating member 290 to assist the operation of a bicycle transmission includes a mounting unit; a input transmission member coupled to the mounting unit, wherein the input transmission member moves to at least a neutral position, to an upshift position and to a downshift position; and an output transmission member coupled to the mounting unit, wherein the output transmission member moves to at least a first output position and a second output position. A rotating member engaging member 394 moves between a rotating member engaging position and a rotating member disengaging position, and a motion transmitting mechanism transmits motion form the rotating member engaging member 394 to the output transmission member. A switching mechanism moves the rotating member engaging member 394 to the rotating member engaging position when the input transmission member is in a least one of the upshift position and the downshift position.
      A power saving apparatus is provided for the assisting apparatus that uses power from a rotating member 290 to assist the operation of the bicycle transmission. The power saving apparatus comprises the rotating member engaging member 394 that moves between a rotating member engaging position and a rotating member disengaging position, a setting mechanism 407' that sets the rotating member engaging member 394 toward the rotating member engaging position, and a power saving unit 1300. The power saving unit 1300 saves power communicated between the setting mechanism 407' and the rotating member engaging member 394 when the setting mechanism 407' attempts to move the rotating member engaging member 394 into the rotating member engaging position and the rotating member engaging member encounters a force that resists the rotating member engaging member 394 being in the rotating member engaging position.
