1. An anti-lock brake device for bicycle, comprising:
an oil pressure tank, having an accommodation space, an oil inlet channel, and an oil outlet channel, wherein the oil inlet channel and the oil outlet channel are connected to the accommodation space;
a valve, slidably located in the oil inlet channel and configured to seal or open an oil inlet of the oil inlet channel;
a movable component, located in the accommodation space, wherein the movable component has a connecting channel, two ends of the connecting channel respectively correspond to the oil inlet and an oil outlet of the oil outlet channel, the movable component is slidable between an initial position and a depressurized position, and the movable component in the depressurized position is located closer to the oil outlet channel than that in the initial position; and
a magnetic force generator, disposed in the accommodation space and surrounding the movable component, wherein the magnetic force generator is configured to generate a magnetic force to slide the movable component from the initial position to the depressurized position, and the magnetic force generator and the valve are coaxial;
wherein when the movable component is in the initial position, the valve does not seal the oil inlet; when the movable component is slid from the initial position to the depressurized position, the valve seals the oil inlet so as to create a depressurized volume in the accommodation space;
wherein the anti-lock brake device further comprises a circuit board, the circuit board is disposed in the oil pressure tank, and the oil inlet channel passes through the circuit board.
