Abstract:
1. An apparatus for controlling a bicycle transmission to set a speed stage of a bicycle, comprising: a shift command communication path for communicating electronic shift commands to select a speed stage of the bicycle; a transmission command communication path for communicating information for controlling the operation of the bicycle transmission; a transmission control unit operatively coupled to the shift command communication path and to the transmission command communication path for receiving the shift commands from the shift command communication path and for generating the information for controlling the operation of the bicycle transmission and outputting the information for controlling the operation of the bicycle transmission on the transmission command communication path; wherein, when the transmission control unit receives at least one shift command requesting a shift through N speed stages to a destination speed stage, where N is an integer greater than one, the transmission control unit generates information for causing the bicycle transmission to move to the destination speed stage and outputs the information for causing the bicycle transmission to move to the destination speed stage on the transmission command communication path; and wherein the shift command requesting a shift through N speed stages comprises a first command signal and a second command signal, wherein the first command signal and the second command signal occur simultaneously.
