    Abstract: A drive unit has three axles, three rotation transmitting members and an acting force detecting unit. The first axle is configured to be rotated by a crank arm. The first rotation transmitting member is arranged on the first axle to transmit rotation of the first axle by the crank arm. The second axle is spaced from the first axle. The second rotation transmitting member is arranged on the second axle, and is operatively engaged with the first rotation transmitting member to transmit rotation of the first rotation transmitting member. The third axle is spaced from the first axle and the second axle. The third rotation transmitting member is arranged on the third axle, and operatively engaged with the second rotation transmitting member to transmit rotation of the second rotation transmitting member. The acting force detecting unit arranged to detect a force acting on the second axle.

    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: A bicycle drive unit includes a motor, a crank axle, a torque combining mechanism, and a clutch mechanism. The crank axle is rotatable about a first rotational axis. The torque combining mechanism is operatively coupled to the motor and the crank axle. The torque combining mechanism has a sprocket mounting portion that is configured to be operatively attached to a sprocket such that the sprocket rotates about a second rotational axis of the sprocket in a first direction as the crank axle rotates about the first rotational axis in the first direction. The clutch mechanism is operatively disposed between the crank axle and the sprocket. The clutch mechanism is configured to rotate the sprocket about the second rotational axis in a second direction as the crank axle rotates about the first rotational axis in the second direction. The second direction is opposite the first direction.
