Abstract: A human-powered vehicle control device includes an electronic controller that controls a transmission device to shift a ratio of a rotational speed of a wheel to a rotational speed of a crank axle in stages. The controller controls the transmission device so that the transmission device performs a first shifting action that shifts the ratio by only one stage in a case where a shifting condition is satisfied. The transmission device is controlled by the electronic controller so that the transmission device performs a second shifting action that shifts the ratio by two or more stages in a case where the shifting condition is satisfied and a vehicle state of the human-powered vehicle is a predetermined state. The predetermined state includes a state in which a change amount of a parameter related to the vehicle state is a predetermined amount or greater.

Abstract: An electronic automatically decoupling hub assembly. The decoupling hub assembly has an axle and a hub shell rotationally positioned about the axle. A controller provides automatic activation/deactivation signals to an inductor. The decoupling hub assembly has a bearing rotationally positioned about the axle and a cassette body assembly, having a plurality of teeth, rotationally positioned about the bearing. One or more pawls are provided to engage with at least some of the teeth of the cassette body assembly and a seal is used to contain the pawls within the decoupling hub assembly. A cassette body assembly is coupled with the ratchet ring and an end cap is used to prevent a contaminant from entering into the decoupling hub assembly.

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 bicycle derailleur system is applied to a bicycle and includes a controller, a camera, a derailleur assembly, and the memory device that are electrically connected to the controller. The camera records a real-time video of a road ahead. When the derailleur assembly is operated to shift, the derailleur assembly sends a chain shifting signal to drive the controller to process the video captured by the camera to obtain a section of video between a predetermined time before and after the chain shifting signal. The controller stores the section of the video along with information in the chain shifting signal to the memory device, to establish a basis for image similarity comparison. When the bicycle derailleur system is operated automatically, the image similarity comparison between real-time video recorded by the camera and the sections of the videos stored in the memory device is conducted to determine whether to shift.

Abstract: A human-powered vehicle includes a crank axle, a first rotational body, a wheel, a second rotational body, a transmission body that transmits a driving force between the first rotational body and the second rotational body, a derailleur configured to operate the transmission body to change a transmission ratio, a motor configured to drive the transmission body and an electric actuator configured to operate the derailleur. A control device has an electronic controller configured to control electric actuator and the motor. The electronic controller is configured to control the electric actuator and drive the transmission body with the motor so that the transmission ratio is changed in a predetermined shifting range in upon determining the derailleur has been actuated to change the transmission ratio and a predetermined condition related to pedaling is satisfied.
