A bicycle control device includes a housing member, a control lever member, a shift-operating mechanism and a hydraulic fluid pressure generator. The housing member has an attachment part for attachment to a handlebar, and a grip part extending longitudinally between first and second ends of the grip part. The control lever member pivots respect to the housing member. The shift-operating mechanism is coupled to a shifting device by a control cable. The hydraulic fluid pressure generator has a cylinder and a piston movably disposed within the cylinder to generate fluid pressure for controlling a braking device. The hydraulic fluid pressure generator has an output port that transmits hydraulic pressure generated in the cylinder to outside of the cylinder, and a hydraulic fluid channel coupled to the output port. A connecting part fluidly communicates with the output port through the hydraulic fluid channel, and is connected an external hydraulic hose.

A gearbox having a primary shaft, a secondary shaft, gears forming the gear ratios, sliding gears providing the changes in gear ratio, and forks, each fork having a guide finger and a control barrel. The primary and secondary shafts are connected to one another by the gears. Each gear includes a wheel connected fixedly in terms of rotation to a shaft, and an idling pinion mounted on the other shaft. Each idling pinion includes claws. Each sliding gear collaborates with one or two idling pinions and is moved towards the associated one or two idling pinions by a fork. Each sliding gear includes claws that complement the claws of the idling pinion or pinions with which it collaborates. The barrel includes guide members, each guide member guides the guide finger of the fork. The assembly including the forks, sliding gears, idling pinions and guide members forms a gear selection system.

A bicycle component fixing structure includes at least one bracket including at least one connecting portion and at least one fixing portion. The connecting portion is connected to the bicycle component. The fixing portion extends from the connecting portion and is fixed with respect to an outer peripheral surface of a cylindrical portion having an open end. The fixing portion includes at least one inner surface that opposes an outer peripheral surface of the cylindrical portion, and at least one outer surface that faces in the opposite direction from the inner surface. The fixing portion is fixed to the outer peripheral surface of the cylindrical portion by a pressing force that acts on the outer surface. The bracket fixes the bicycle component to the open end of the cylindrical portion, in a state in which the fixing portion is fixed to the outer peripheral surface of the cylindrical portion.

An e-bike interface is a hybrid wired/wireless e-bike control system that integrates wireless bicycle components into operation of an e-bike. The e-bike interface provides a frame-mounted control and display that is wired to, for example, an assist motor and a battery, and provides a wireless communication bridge between wireless bicycle components and corresponding wireless controls located on a handlebar.

A generator assembly comprises an internal combustion engine connected to a generator by a transmission. The transmission comprises multiple outputs such that another mechanically powered device can be driven by the engine. The transmission includes a shift mechanism for selecting which output receives power from the engine. The assembly may also be a vehicle and one of the devices can be a drivetrain for powering a drive wheel of the vehicle.

An arrangement for actuating a shift element for a bottom bracket gearbox (1) includes a shift ring (4) rotatably mounted in a housing (3) and assigned to a gearbox component. A shift pawl (5) for locking or releasing the shift ring (4) is assigned to the shift ring (4) for shifting a gear stage. A support region mechanically reinforces the housing (3) and is provided at least along a contact region (14) between an inner wall (8) of the housing (3) and an outer circumference of the shift ring (4). The contact region (14) is defined by reaction forces (16) acting when the shift ring (4) is locked.

A control value is corrected and learned based on a difference angle between a drum shaft conversion spindle integration angle s obtained by converting a detected spindle angle detected by a spindle angle sensor 78 into a drum angle and a detected drum angle d detected by a drum angle sensor 89, over a predetermined learning time T from when the shift motor 61 is driven, and a drive engagement portion 83d of a shift driven gear 83 reduces the play angle to abut on a driven engagement portion 82d of a drum center 82 to accompany the driven engagement portion 82d. In this manner, rotation of a shift drum 80 can be accurately controlled by the shift motor 61, while the number of components of a variable speed drive mechanism 60 is reduced.
