ABSTRACT:
A bicycle shifting control apparatus is provided with a gear selection signal receiving section, a gearshift determination section and a gearshift output section. The gear selection signal receiving section selectively receives a first gear selection signal and a first/second gear selection signal. The gearshift determination section determines a first rider shift intention for first gear shifting when the first gear selection signal is received, which meets a first signal criteria, and determines a second rider shift intention for performing second gear shifting in addition to the first shifting when the first/second gear selection signal is received by, which meets a second (different) signal criteria. The gearshift output section outputs a first gearshift signal upon determining the first rider shift intention or the second rider shift intention exists and outputs a second gearshift signal upon determining that the second rider shift intention exists.
