Abstract: The disclosure provides a wear warning device including a caliper, two brake pads, an elastic component and a first switch. The caliper has two push parts. The two push parts are respectively disposed at a first wall surface and a second wall surface of the caliper. The brake pads are located between the two push parts. The elastic component includes two arm parts and a connection part located between the arm parts. The arm parts are respectively disposed on the brake pads. The first switch is located between the arm parts. When the brake pads are in a worn-out state and the push parts are moved toward each other to force the brake pads to clamp a brake disk and to force the two arm parts to move toward each other, one of the arm parts activates the first switch to produce a wear warning signal.

Abstract: A derailleur includes a fixed component, a movable component, a linkage component, a deceleration component and a drive component. The fixed component is for being fixed to a bicycle frame. The movable component is for being fixed to a chain guide. The linkage component includes a first linkage and a second linkage. Two ends of the first linkage pivot on the fixed component and the movable component, respectively. Two ends of the second linkage pivot on the fixed component and the movable component, respectively. The deceleration component includes a circular spline, a flex spline and a wave generator. The flex spline is disposed inside the circular spline, for rotating the first linkage and the second linkage relative to the fixed component. The wave generator is disposed inside the flex spline. The drive component is connected to the wave generator, for rotating the wave generator.

Abstract: A bicycle braking and parking device includes a casing, two brake pads, a locking pin, and an electromagnetic driver. The casing has an accommodation space and two pistons located at two opposite sides of the accommodation space. The accommodation space can accommodate part of a brake disk. The brake pads are located at the accommodation space and located between the pistons. The pistons can push the brake pads, and the brake pads can clamp the brake disk. The locking pin is movably disposed on the casing. The electromagnetic driver can force the locking pin to move between a released position and a locked position. when the locking pin is in the released position, the locking pin is separated from the brake disk. When the locking pin is in the locked position, the locking pin is inserted into the brake disk to limit a motion of the brake disk.
