Abstract: A human-powered vehicle includes a crank axle, a first rotational body, a wheel, a second rotational body, a transmission body that transmits a driving force between the first rotational body and the second rotational body, a derailleur configured to operate the transmission body to change a transmission ratio, and a motor configured to drive the transmission body. A control device has an electronic controller configured to control the motor and drive the transmission body with the motor upon determining the derailleur has been actuated to change the transmission ratio and a predetermined condition related to pedaling is satisfied, and control the motor to increase a rotational speed of the motor as a difference of a first rotational speed, which is calculated in correspondence with a rotational speed of the wheel and the transmission ratio, and a predetermined rotational speed or a rotational speed in a predetermined range increases.

Abstract: A bicycle controller includes an electronic control unit that controls a transmission device. The transmission device is configured to change 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. The motor transmits torque to an upstream side of the transmission device in a transmission path of manual driving force that is input to the crank. The electronic control unit is configured to switch 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 is configured to control a rotational speed of the motor in accordance with the ratio in the second mode.
