Abstract: A bicycle control device includes an electronic controller that controls a motor, which assists propulsion of a bicycle. The electronic controller is configured to decrease an output of the motor to less than or equal to a limit value upon determining a shifting device is performing a shifting action to change a transmission ratio of the bicycle. The electronic controller is further configured to change at least one of the limit value of the output of the motor and a time in which the output of the motor is decreased upon determining the shifting device is performing the shifting action in accordance with at least one of an actuation state of the shifting device in the shifting action and a parameter of the bicycle that is changed by the shifting action performed by the shifting device.

Abstract: A bicycle controller includes an electronic control unit that controls a transmission unit and a motor in accordance with a shift request that changes the transmission ratio. If the transmission ratio is changed in multiple steps in accordance with the shift request, then the electronic control unit selectively executes one of first and second shifting operations. In the first shifting operation, the output of the motor is limited and the transmission unit is operated to reach a requested transmission ratio that corresponds to the shift request. In the second shifting operation, the output of the motor is limited and the transmission unit is operated to reach an intermediate transmission ratio of the requested transmission ratio, and after the electronic control unit temporarily reduces the limitation on the output of the motor, the electronic control unit again limits the output of the motor and operates the transmission unit.

Abstract: A bicycle control apparatus is basically provided for controlling a bicycle having a drive assistance electric motor. The bicycle control apparatus includes a manual drive force detector, a shift state detector and a controller. The manual drive force detector detects a manual drive force. The shift state detector detects a shift state of the bicycle. The controller issues a command for controlling a drive assistance force to be outputted by the drive assistance electric motor in accordance with the manual drive force detected by the manual drive force detector. The controller controls the drive assistance force to delay a reduction in the drive assistance force in relation to a reduction in the manual drive force upon determining the manual drive force is reduced, and controls the delay in the reduction of the drive assistance force in accordance with the shift state of the bicycle.

Abstract: A bicycle control device controls a motor to assist driving of a wheel of a bicycle. The bicycle control device includes a controller configured to control the motor and an operation unit configured to be operated to switch operation modes of the motor. The controller includes at least a walk mode as the operation modes. In a case that a rotation speed of a wheel becomes lower than or equal to a predetermined value while the motor is driven in the walk mode, the controller is configured to control the motor so as to gradually decrease output of the motor and then stop driving the motor.

Abstract: A bicycle control apparatus is provided that permits a determination of a rotating body to be detected of a sensor that outputs a signal that reflects the rotational speed of a rotating body, and a bicycle assist device equipped with this control apparatus. The bicycle control apparatus includes a controller that, based on an output of a first sensor for outputting a signal that reflects a rotational speed of a rotating body provided to a bicycle, and an output of a second sensor for outputting a signal that reflects a rotational speed of a rotating body provided to the bicycle, determines whether or not the detection target of the first sensor and the detection target of the second sensor are the same rotating body.

Abstract: A bicycle control apparatus is provided with a controller for controlling an output of an assist motor according to a manual drive force. The controller is configured to selectively set a first control state and a second control state, in which output states of the assist motor with respect to the manual drive force are different from each other. The controller controls the output of the assist motor so that a response speed of the assist motor with respect to changes in the manual drive force in the first control state will be faster than the response speed of the assist motor with respect to changes in the manual drive force in the second control state, when a crank of a bicycle is rotated from a stopped state and/or when a rotational speed of the crank is less than or equal to a prescribed first speed.
