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; and
a movable component, located in the accommodation space, wherein the movable component has a connecting channel penetrating through the movable component, two opposite 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;
wherein when the movable component is in the initial position, the movable component presses against the valve so as to open the oil inlet; when the movable component is slid from the initial position to the depressurized position, the movable component is moved away from the valve, the valve seals the oil inlet, a first volume is produced between the connecting channel and the oil inlet, and a second volume is removed from between the connecting channel and the oil outlet;
wherein the first volume is larger than the second volume, and a difference between the first volume and the second volume creates a depressurized volume.
