Abstract: A human-powered vehicle drive unit that reduces loss of human driving force includes an electric motor, a crankshaft, an output portion, a speed reducer, and a clutch. The electric motor is configured to assist in propulsion of a human-powered vehicle. The output portion is coupled to the crankshaft. The speed reducer reduces a rotational speed of the electric motor in multiple steps. The clutch is provided between the output portion and the speed reducer. In a case in which the crankshaft rotates in a first rotational direction, the output portion is configured to rotate in the first rotational direction. In a case in which the crankshaft rotates in a second rotational direction, the output portion is configured to rotate in the second rotational direction. The clutch is configured to transmit a rotational force of the electric motor to the output portion from the speed reducer.

Abstract: A battery holder is configured to appropriately hold a battery unit. The battery holder includes a first holding portion that supports a first end of a battery unit while in an installed state where the battery unit is held by the battery holder. The first holding portion includes a movable member and a first biasing member. The movable member includes a first support surface that contacts the first end of the battery unit while in the installed state. The movable member is movable relative to a frame of a human-powered vehicle while in a mounted state where the battery holder is mounted to the frame of the human-powered vehicle. The first biasing member biases the movable member toward the battery unit.

Abstract: A bicycle drive unit includes a crank axle, a motor, an output member and a torque combining mechanism. The crank axle is rotatable about a first rotational axis. The motor has an output shaft rotatable about a second rotational axis. The output member is rotatable about the first rotational axis in a first rotational direction as the crank axle rotates about the first rotational axis in the first rotational direction. The torque combining mechanism operatively couples the output shaft of the motor to the output member to transmit rotation of the output shaft of the motor to the output member. The torque combining mechanism operatively separates the output shaft of the motor from the output member for preventing rotation of the crank axle from being transmitted to the output shaft of the motor as the crank axle rotates about the first rotational axis in a second rotational direction.
Abstract translation: 自行车驱动单元包括曲柄轴，马达，输出构件和扭矩组合机构。 曲柄轴可绕第一旋转轴线旋转。 马达具有可围绕第二旋转轴线旋转的输出轴。 当曲柄轴沿第一旋转方向围绕第一旋转轴线旋转时，输出构件可绕第一旋转轴线以第一旋转方向旋转。 扭矩组合机构将马达的输出轴可操作地连接到输出构件，以将马达的输出轴的旋转传递到输出构件。 扭矩组合机构可操作地将马达的输出轴与输出构件分开，以防止当曲柄轴沿第二旋转方向围绕第一旋转轴线旋转时曲柄轴的旋转传递到马达的输出轴。

Abstract: A human-powered vehicle component includes a housing and a joint provided on the housing and configured to be attached to a support of the human-powered vehicle by a fastener. The joint includes a metal base, a metal coupling portion provided on the base and coupled to the fastener, and an intermediate portion provided between the coupling portion and the base. The base includes a first material having a first standard electrode potential. The coupling portion includes a second material having a second standard electrode potential. The intermediate portion is formed by a third material having a third standard electrode potential or a fourth material having an electric insulating property. A difference of the third and first standard electric potentials and a difference of the third and second standard electrode potentials are each smaller than a difference of the first and second standard electrode potentials.

Abstract: A bicycle apparatus comprises an assist motor, an ABS unit, an assist selection switch and a control device. The ABS unit is configured to control a braking force that is applied to a bicycle wheel. The assist selection switch is configured to switch the assist motor between an ON mode in which the assist motor is ON and an OFF mode in which the assist motor is OFF. The control of the ABS unit by the control device is dependent on an operation of the assist selection switch. The control device is configured to control the assist motor to add the assisting force to the manual drive force when the assist motor is in the ON mode. The control device is configured to set the ABS unit to an ABS operating mode to begin control of the ABS unit when the assist selection switch selects the ON mode.

Abstract: A method of controlling an ABS unit is provided for controlling a braking force of a bicycle. The method includes determining whether a vehicle speed is greater than or equal to a prescribed speed, and then determining whether the bicycle is in a prescribed state. The prescribed state is at least one of a first state and a second state. The first state is a state in which a difference between a rotational speed of the front wheel and a rotational speed of the rear wheel is greater than or equal to a prescribed rotational speed. The second state is a state in which a change in the rotational speeds of the front and rear wheels is greater than or equal to a prescribed value. The method further includes controlling the ABS unit upon based on the vehicle speed and the prescribed state.
