A gear shift control apparatus (15, 65, 85) comprises a shift command input that receives shift commands indicating a desired gear shift operation, a control output that outputs controls signals that control a gear shift unit to shift the bicycle transmission, a gear shift monitor (24) that monitors a progress of a gear shift operation by the gear shift unit, and a gear shift controller (23) operatively coupled to the shift command input, to the control output, and to the gear shift monitor (24). The gear shift controller (23) receives a shift command and outputs a control signal that controls the operation of the gear shift unit to shift the bicycle transmission to a target gear. The gear shift controller (23) modifies the control signal when the gear shift controller (23) receives a second shift command corresponding to a second target gear that differs from a first target gear corresponding to a first shift command and the gear shift operation initiated by the first shift command has not completed. <IMAGE>
