Abstract: A drive train comprises a sprocket arrangement and a force-transmission coefficient. The sprocket arrangement includes a plurality of rear sprockets and a plurality of gear ratios respectively corresponding to the plurality of rear sprockets. The plurality of gear ratios includes a largest gear ratio and a smallest gear ratio. The sprocket arrangement includes at least one individual sprocket-space provided between two adjacent rear sprockets among the plurality of rear sprockets. The force-transmission coefficient is obtained by dividing a total gear range quotient by a total number of the at least one individual sprocket-space. The force-transmission coefficient is equal to or larger than 0.97 and is equal to or smaller than 1.36. The total gear range quotient is obtained by dividing the largest gear ratio by the smallest gear ratio.

Abstract: A human-powered vehicle control device is provided for controlling a human-powered vehicle. The human-powered vehicle control device includes an electronic controller that controls a human-powered vehicle component in accordance with a control state including first and second modes. The electronic controller changes a transmission ratio of a transmission device in accordance with a first shifting condition in the first mode, and changes the transmission ratio in accordance with a second shifting condition in the second mode. The electronic controller changes the first shifting condition in accordance with a converging reference value, which is related to a traveling state of the human-powered vehicle, for a case where the human-powered vehicle is in a riding converging state in the first mode, and changes the second shifting condition in accordance with a converging reference value for a case where the human-powered vehicle is in the riding converging state in the second mode.

Abstract: A human-powered vehicle control device controls the transmission to initiate a shifting operation based on a set of prescribed conditions that changes the transmission ratio of a human-powered vehicle. The control device includes an electronic controller that switches between a first control state for controlling the transmission to change the transmission ratio in accordance with a first prescribed set of conditions, and a second control state for controlling the transmission to prevent the change of the transmission ratio as compared with if the electronic controller is in the first control state. The electronic controller switches between the first control state and the second control state in accordance with a detection of at least one of a steering state of the human-powered vehicle, a surface condition of a travel path on which the human-powered vehicle travels, and a pedaling preparation state related to the pedals of the human-powered vehicle.

Abstract: A control device for a human-powered vehicle including a motor that applies a propulsion force to the human-powered vehicle, a crank axle, a driving wheel, and a transmission that automatically changes a transmission ratio of a rotational speed of the driving wheel to a rotational speed of the crank axle in accordance with a travel state of the human-powered vehicle. The control device includes an electronic controller that controls the motor in accordance with a human driving force input to the crank axle. The controller changes an assist state related to at least one of an assist ratio of an assist force by the motor to a predetermined human driving force and the assist force by the motor in accordance with the human driving force and controls the transmission to maintain the transmission ratio upon determining a parameter related to the human driving force satisfies a predetermined condition.
