A bicycle controller includes an electronic control unit. The electronic control unit controls a transmission device that changes a ratio of a rotational speed of a wheel of a bicycle to a rotational speed of a crank of the bicycle, and a motor that transmits torque to an upstream side of the transmission device in a transmission path of a manual driving force that is input to the crank. The electronic control unit switches between a first mode that drives the motor in accordance with the manual driving force and a second mode that allows the motor to be driven to assist walking of the bicycle. The electronic control unit controls the transmission device to change the ratio upon detection of the electronic control unit switching between the first mode and the second mode or the electronic control unit being in the second mode.
