Abstract: A hydraulic braking device includes an engaging base, a hydraulic brake, and a locking device. The hydraulic brake is provided on the engaging base. The locking device is adapted to fix the engaging base on a suspension fork of a bicycle, and includes a bolt and a handle, wherein the bolt passes through the engaging base to be screwed into a tapped hole of the suspension fork. The handle has a cam-shaped head pivotally connected to the bolt, and is pivotable between a first position and a second position. When the handle is located at the first position, the head presses against the engaging base to fix the engaging base on the suspension fork. When the handle is located at the second position, the engaging base is no longer being pressed against by the head, whereby the engaging base is movable relative to the suspension fork.

Abstract: A quick release device for bicycle wheel is disclosed, including a mandrel, a wrench, at least one key, a limiting member, and an elastic member. The mandrel includes a shaft and an axial sleeve positioned at one terminal of the shaft and formed with multiple first grooves. The wrench includes a sleeve mounted on the axial sleeve, and is movable between a first position and a second position. The sleeve includes at least one second groove, wherein the key is positioned within one of the first grooves and the second groove when the sleeve is at the first position; the key is apart from one of the first grooves when the sleeve is the second position. The limiting member fits around the mandrel and includes a stopper. The elastic member is between the key and the stopper. Whereby, the application strength and lifetime can be increased with a lightweight feature.
