Abstract
A bicycle control device is provided that uses power from a rotating member to assist the operation of a bicycle mechanism, wherein the control device includes an input member that requests assistance of the rotating member and an output member that is assisted by the rotating member, and wherein the input member electrically moves from a first position to a second position and then to a third position. A method of operating the control device comprises the steps of providing an input signal for moving the input member from the first position to the second position and then to the third position; sensing a position of the input member with an input position sensor; and determining whether the input position sensor indicates the input member is in the third position.
