Abstract: A bicycle driving device that allows a second motor to be reduced in size includes a first planetary mechanism, a first motor, a second motor, and a speed reduction mechanism. The first planetary mechanism includes a first input body to which rotation of a crank is input, a first output body that rotates when the first input body rotates, and a first transmission body that transmits rotation of the first input body to the first output body. The first motor is capable of rotating at least one of the first input body, the first output body, and the crank. The speed reduction mechanism reduces rotation produced by the second motor in speed and transmits the rotation to the first transmission body.

Abstract: A bicycle drive unit has a planetary gear mechanism, a switching mechanism, a motor and a housing. The planetary gear mechanism includes an input body, an output body and a plurality of transmission paths having different transmission ratios between the input body and the output body. The switching mechanism is configured to switch between the plurality of transmission paths. The motor is configured to transmit rotational force to the input body. The housing rotatably supports a crankshaft and on which are provided the planetary gear mechanism, the switching mechanism and the motor. A manual drive force that is input to the crankshaft joins with a rotational force that is output from the output body of the planetary gear mechanism in a transmission path of a driving force from the output body of the planetary gear mechanism to a wheel.

Abstract: A bicycle drive unit has a transmission and a motor that transmits torque to the transmission. The transmission includes first and second input side rotating bodies, first and second output side rotating bodies, an output unit and a switching mechanism. The first and second output side rotating bodies are coupled to the first and second input side rotating bodies, respectively. The switching mechanism switches between a first state in which rotation of the first input side rotating body is transmitted to the output unit, and a second state in which rotation of the second input side rotating body is transmitted to the output unit. Only torque of the motor is transmitted from the first and second input side rotating bodies to the output unit, while torque outputted from the output unit merges with a manual drive force in a drive force transmission path from the output unit to a wheel.

Abstract: A bicycle transmission includes an axle, an input component, a power transmission mechanism, a shift mechanism and an output component. The input component receives manually applied rotational force. The output component is rotatably supported by the axle. The power transmission mechanism transmits the rotational force of the input component to the output component through one of a plurality of power transmission paths. The shift mechanism includes a shift input member, a shift control member, a first saver spring and a second saver spring. The shift input member is settable in a plurality of rotational positions. The shift control member rotates in conjunction with movement of the shift input member to select one of the power transmission paths. In the shift mechanism, as the shift input member rotates in the first direction, the shift control member receives the rotational force applied in a first direction through the first saver spring.

Abstract: A bicycle drive unit includes a planetary gear mechanism, a first motor and a power switching mechanism. The planetary gear mechanism includes an input body, an output body and a transmitting body. The input body receives a rotational input of a crankshaft. The output body outputs the rotation of the planetary gear mechanism to the outside. The first motor controls the rotation of the transmitting body. The output body rotates in a direction corresponding to a first rotational direction when rotation in the first rotational direction is input from the crankshaft to the input body. The power switching mechanism rotates the output body in a direction corresponding to a second rotational direction when rotation in the second rotational direction is input from the crankshaft to the input body.

Abstract: A bicycle controller limits decreases in the assist force when the rotational speed of a crank changes. The bicycle controller can be mounted on a bicycle including a first transmission having at least two shift stages and configured to change a ratio of rotation of a wheel to rotation of a crank, a motor that provides assistance to human power input to the crank, and a second transmission configured to transmit a rotation force from the motor to a power transmission path extending from the crank to the wheel without changing the ratio of the rotation of the wheel to the rotation of the crank. The bicycle controller includes an electronic control unit that controls the second transmission in accordance with a condition of the bicycle and either one of a condition of the first transmission and a shift instruction to the first transmission.
