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.

Abstract: A bicycle drive unit is basically provided with an assist motor and a housing such that the distance between a crankshaft and a rear end of the housing is prevented from becoming long. The assist motor is configured to apply an assisting force to a manual drive force, which is inputted from a crankshaft. The housing is provided to the assist motor and at least a part of the crankshaft. The housing is disposed around the crankshaft. The housing is formed so that, when the bicycle drive unit is attached to a bicycle frame, the minimum distance from a center axis of the crankshaft and the rear end surface of the frame on the rear end side of the housing is equal to or less than 50 mm and greater than the radius of the crankshaft, as viewed from parallel to the center axis of the crankshaft.

Abstract: A continuously variable bicycle transmission mechanism includes a ring roller, at least one conical planetary roller, a sun roller and a carrier. The at least one conical planetary roller is frictionally engaged with the ring roller. The at least one conical planetary roller is rotatable about a rotational axis of a roller axle of the at least one conical planetary roller. The sun roller is frictionally engaged with the at least one conical planetary roller. The carrier rotatably supports both ends of the roller axle of the at least one conical planetary roller. The carrier is movable along an axis with the at least one conical planetary roller.
