Abstract:
An assisting apparatus for using power from a rotating member to assist operation of a bicycle transmission comprising:a mounting member; a cam member coupled to the mounting member for rotation around a cam axis, wherein the cam member has a cam surface; a cam follower cooperating with the cam surface for moving in response to rotation of the cam member; a transmission actuating element coupling member for communicating movement of the car follower to a transmission actuating element; a first coupling member that moves between a first engaged position and a first disengaged position; wherein the first coupling member rotates the cam member when the first coupling member is in the first engaged position; an operating member for moving the first coupling member to the first engaged position; and a decoupling member that moves the first coupling member to the first disengaged position in response to a rotational position of the cam member.
