Abstract: A control device includes an electronic controller that controls a motor of a human-powered vehicle. The electronic controller outputs a signal to change a transmission ratio by operating a linking body with a derailleur while driving the linking body with the motor where a first condition related to pedaling is satisfied. The first condition relates to at least one of a pedal state, a human driving force input to the pedal, a crank arm state, a human driving force input to the crank arm, a crank axle angular acceleration, a rotational state of a first rotational body, a tire state, a rotational state of a second rotational body, an operational state of the linking body, an operational state of the derailleur, a rotational state of the motor, an electric energy supplied to the motor, a handlebar state, a saddle state, and positional information of the human-powered vehicle.

Abstract: A bicycle rear derailleur includes a base element including a first attachment end for coaxial installation on a rear-wheel axis and a second attachment end, a movable element movable relative to the base element, a linkage mechanism connecting the movable element to the base element, and a chain guide arrangement rotatably connected to the movable element. The second attachment end is coupled to the linkage mechanism. The first attachment end includes a first arm and a second arm, which are spaced apart in an axial direction with respect to the rear-wheel axis. The base element includes an angular position adjustment structure that adjusts an angular position of the derailleur relative to a bicycle frame by rotating the first arm and the second arm about the rear-wheel axis. The angular position adjustment structure is disposed between the first and second attachment ends in a radial direction of the rear-wheel axis.

Abstract: A bracket device is configured to mount a bicycle rear derailleur on a rear-wheel axis of a bicycle. The bracket device includes a frame attachment end for coupling to a bicycle frame and a derailleur attachment end for coupling to the bicycle rear derailleur. The frame attachment end has a first arm and a second arm, which are spaced apart in an axial direction with respect to the rear-wheel axis. The first arm has a first attachment opening through which the rear-wheel axis coaxially passes in a mounting state of the bracket device. The second arm has a second attachment opening through which the rear-wheel axis coaxially passes in the mounting state of the bracket device. The derailleur attachment end has a third attachment opening configured to receive a derailleur fastener for coupling to the base element of the bicycle rear derailleur.

Abstract: A human-powered vehicle control device for a human-powered vehicle comprises an electronic controller. The electronic controller is configured to control a motor, which applies a propulsion force to the human-powered vehicle, in accordance with a human driving force input to the human-powered vehicle. The electronic controller is configured to control the motor to change at least one of a maximum value of an output of the motor, a first changing ratio of an increase rate of the output of the motor to an increase rate of the human driving force, and a second changing ratio of a decrease rate of the output of the motor to a decrease rate of the human driving force in accordance with transmission information related to a transmission ratio in a power transmission path between an input rotational shaft of the human-powered vehicle and a wheel of the human-powered vehicle.
