Abstract: The disclosure provides a bicycle braking system including a lever assembly, a parking brake mechanism, and a positioning assembly. The lever assembly includes a housing and a brake lever pivotably disposed on the housing. The housing has a first positioning structure, and the brake lever has an engagement portion. The parking brake mechanism includes a control handle pivotably disposed on the housing so as to be engaged or disengaged with the engagement portion. The positioning assembly includes a positioning handle pivotably disposed on the control handle and having a locked position and an unlocked position. when the positioning handle is in the locked position, the positioning handle is positioned at the first positioning structure so as to stop the control handle from be pivoted with respect to the housing. When the positioning handle is in the unlocked position, the positioning handle is removed from the first positioning structure.

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.

Abstract: The disclosure provides a bicycle caliper including a casing assembly and a plurality of pistons. The casing assembly has a first fluid inlet, a second fluid inlet, a first fluid channel, a plurality of piston chambers, and a second fluid channel. The first fluid channel has a first connection opening and a second connection opening opposite to each other. The first connection opening and the second connection opening of the first fluid channel are respectively in fluid communication with the first fluid inlet and the second fluid inlet. The first fluid channel penetrates through the piston chambers. Two opposite openings of the second fluid channel are respectively in fluid communication with the first connection opening and the second connection opening of the first fluid channel, and the second fluid channel does not penetrate through the piston chambers. The pistons are respectively and movably disposed in the piston chambers.
