A bicycle gear changing control apparatus includes a controller that is programmed to control a gear changing state of a bicycle transmission according to an operation of a gear changing operating device upon determining a bicycle traveling speed is greater than a first speed. The controller controls the transmission automatically to be in a first prescribed gear changing state upon determining the bicycle traveling speed becomes less than or equal to the first speed and upon determining a gear ratio of a current gear changing state of the transmission is larger than a preset gear ratio of the first prescribed gear changing state. The controller controls the transmission automatically, after controlling the transmission to be in the first prescribed gear changing state, to a larger gear ratio than the gear ratio of the first prescribed gear changing state, upon determining the bicycle traveling speed becomes greater than a second speed.
