A bicycle shifting control apparatus comprising: a gear selection signal receiving section that selectively receives a first gear selection signal and a first/second gear selection signal; a gearshift determination section that determines a first rider shift intention for first gear shifting when the first gear selection signal is received by the gear selection signal receiving section, 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 the gear selection signal receiving section, which meets a second signal criteria that is different from the first signal criteria; a gearshift output section that outputs a first gearshift signal upon the gearshift determination section determining the first rider shift intention or the second rider shift intention and that outputs a second gearshift signal upon the gearshift determination section determining the second rider shift intention; wherein the gearshift determination section determines the first signal criteria is met when the first gear selection signal is received via a first input of the gear selection signal receiving section, and the gearshift determination section determines the second signal criteria is met when the first/second gear selection signal is received via a second input of the gear selection signal receiving section that is different than the first input of the gear selection signal receiving section; and characterized by: a first gearshift operating device having a first single rider gear input member (41,42,43,44) that is selectively operable in a first operation manner that produces the first gear selection signal and that is selectively operable in a second operation manner that produces the first/second gear selection signal; wherein the first single rider gear input member (41,42) of the first gearshift operating device is movably mounted to move between a rest position, a first operation position and a second operation position that is past the first operation position during a single progressive stroke of the first single rider gear input member (41,42) from the rest position to the second operation position such that the first operation manner occurs when the first single rider gear input member (41,42) is moved from the rest position to the first operation position and such that the second operation manner occurs when the first single rider gear input member (41,42) is moved from the rest position to the second operation position. a gear selection signal receiving section that selectively receives a first gear selection signal and a first/second gear selection signal;
