Abstract: A bicycle transmission device basically includes an input rotational shaft, an output part, a transmission mechanism and a switching mechanism. The transmission mechanism includes a first rotating body configured to transmit rotation of the input rotational shaft and a fourth rotating body configured to transmit the rotation of the input rotational shaft. The switching mechanism is configured to selectively switch between a first state in which a ratio of a rotational speed of the output part to a rotational speed of the input rotational shaft is a first ratio and a second state in which the ratio is a second ratio that is different from the first ratio. The switching mechanism includes a one-way clutch and a switching unit.

Abstract: A bicycle shifting device includes a first shifting mechanism, a transmission mechanism, and a setting mechanism. The setting mechanism sets paths in the transmission mechanism to transmit rotation from an input body to an output body at transmission ratios of at least three steps. The transmission mechanism establishes a first path transmitting the rotation at one of first and second transmission ratios by changing a rotational speed with the first shifting mechanism, and a second path transmitting the rotation at a greater transmission ratio than the first and second transmission ratios by changing the rotational speed with a different shifting mechanism from the first shifting mechanism. The first path includes first and second planetary mechanisms. The setting mechanism sets the transmission mechanism so that the rotational speed is not changed by the first planetary mechanism in the second path.

Abstract: A bicycle drive unit is basically provided with an input rotational shaft, an output part, a transmission mechanism, an assist motor and a switching mechanism. The transmission mechanism has at least two shift stages, and is configured to change a speed of a rotational input that is input from the input rotational shaft and output this rotational input to the output part. The assist motor is coupled to a power transmission path from the input rotational shaft to the output part, and is driven according to a manual drive force. The switching mechanism is configured to switch a gear changing state of the transmission mechanism by using a rotational force of the assist motor.
