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.

A control device is provided for controlling for a brake system of a human-powered vehicle that includes a rotary body and a brake device that brakes the rotary body. The control device of the brake system includes an acquisition portion acquiring information related to at least one of the rotary body and the brake device to appropriately brake the rotary body with the brake device.

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.

To provide a brake controller and a brake system that appropriately brake a rotary body of a human-powered vehicle, a brake controller includes one or more processors configured to programmatically control a braking portion of a brake device so that the braking portion brakes a rotary body of the human-powered vehicle based on first information related to travel of the human-powered vehicle, the first information excluding a road surface gradient.
