Abstract: A human-powered vehicle control device includes an electronic controller that controls a motor. The motor assists in propulsion of a human-powered vehicle including a transmission configured to change, in steps, a first ratio of a rotational speed of a drive wheel to a rotational speed of a rotary body to which human drive force is input. The controller changes a motor control state from a third control state to a fourth control state when the first ratio is changed by the transmission or a signal is received for changing the first ratio. The controller changes the motor control state from the fourth control state to a fifth control state in accordance with a value related to at least one of a speed of the human-powered vehicle, the human drive force, an inclination angle of the human-powered vehicle, and a state of a rider of the human-powered vehicle.

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.

Abstract: A drive train for a human-powered vehicle comprises a drive unit, a sprocket arrangement, and a total gear range quotient. The drive unit includes a motor configured to impart propulsion to the human-powered vehicle. The sprocket arrangement is operatively coupled to the drive unit. The sprocket arrangement comprises a plurality of rear sprockets and a plurality of gear ratios respectively corresponding to the plurality of rear sprockets. The plurality of gear ratios includes a largest gear ratio and a smallest gear ratio. The total gear range quotient is obtained by dividing the largest gear ratio by the smallest gear ratio. The total gear range quotient is larger than 5.

Abstract: An attachment member attaches a bicycle battery pack to a frame of a bicycle. The attachment member includes a coupling member and a lock. The coupling member restricts movement of the bicycle battery pack relative to the frame while the attachment member is in an attachment state in which the battery pack is attached to the frame. The coupling member extends through a first frame portion of the frame and coupled to a first housing portion of the housing while the attachment member is in the attachment state. The lock is provided on the coupling member and switchable between a restriction state that restricts movement of the coupling member relative to the housing and the frame, and a release state that permits movement of the coupling member relative to the housing and the frame while the attachment member is in the attachment state.
