Abstract
A bicycle shifting control apparatus comprises a transmission controller configured to control a guide actuator of a derailleur to move a chain guide of the derailleur between a plurality of shift positions in response to an input shifting signal. The transmission controller is configured to control, in a shifting operation of the chain guide between adjacent two shift positions of the plurality of shift positions, the guide actuator to temporarily decelerate the chain guide at a deceleration position defined between the adjacent two shift positions so that the bicycle chain engages with and/or disengages from one of the sprockets having a shift assist structure prior to completion of the shifting operation of the chain guide.
