Abstract: A transmission control system is configured to be used with a human-powered vehicle that includes a crank, a first rotation body rotated independently from the crank, a drive wheel, a second rotation body rotated independently from the drive wheel, a transfer body that transfers rotation force between the first and second rotation bodies, and a transmission that controls the transfer body and shifts a transmission ratio. The transmission control system includes a motor that drives the transfer body, a first detector that detects at least one of acceleration and vibration of the human-powered vehicle, and an electronic controller configured to control the motor in accordance with a detection result of the first detector upon generation of a shift request for the transmission in a state in which the drive wheel is rotated and a rotational angle of the crank is maintained in a predetermined range.

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 controls a motor in accordance with the riding environment of a bicycle. The bicycle controller includes an electronic control unit that is configured to control a motor that assists in propulsion of a bicycle in accordance with a manual driving force. The electronic control unit is further configured to sets a response speed of the motor with respect to a change in the manual driving force for a case in which a vehicle speed of the bicycle is less than or equal to a first speed to be different from the response speed for a case in which the vehicle speed of the bicycle exceeds the first speed.

Abstract: A bicycle drive unit is basically provided with an assist motor and a housing such that the distance between a crankshaft and a rear end of the housing is prevented from becoming long. The assist motor is configured to apply an assisting force to a manual drive force, which is inputted from a crankshaft. The housing is provided to the assist motor and at least a part of the crankshaft. The housing is disposed around the crankshaft. The housing is formed so that, when the bicycle drive unit is attached to a bicycle frame, the minimum distance from a center axis of the crankshaft and the rear end surface of the frame on the rear end side of the housing is equal to or less than 50 mm and greater than the radius of the crankshaft, as viewed from parallel to the center axis of the crankshaft.
