Abstract
A pressure modulator for an anti-lock braking system of a bicycle. The pressure modulator includes a cylinder, and a piston having a through opening for hydraulic fluid, the piston being situated inside the cylinder and subdividing the cylinder into a first accumulator chamber and a second accumulator chamber, the first and second accumulator chambers being connectable to each other via the through opening. The pressure modulator further includes a valve system, which includes a closing element and an actuating device for the closing element, the closing element being situated in the through opening, and the actuating device being situated at a bottom of the cylinder, and an actuator for moving the piston.
