Abstract: The disclosure provides an anti-lock brake device including an oil pressure tank, a valve, and a movable component. The oil pressure tank has an accommodation space, an oil inlet channel, and an oil outlet channel connected to the accommodation space. The valve is slidably located in the oil inlet channel and for sealing or opening an oil inlet of the oil inlet channel. The movable component is located in the accommodation space and has a connecting channel corresponding to the oil inlet and an oil outlet of the oil outlet channel. When the movable component is slid to a depressurized position, the movable component is moved away from the valve for sealing the oil inlet, a first volume is produced between the connecting channel and the oil inlet, and a second volume, smaller than the first volume, is removed from between the connecting channel and the oil outlet.

Abstract: A brake system includes a first and a second hydraulic brake assembly, a first and a second switch and a first electronic brake assembly. The first hydraulic brake assembly includes a first brake caliper and a first brake lever connected to each other. The second hydraulic brake assembly includes a second brake caliper and a second brake lever connected to each other. The first switch is activated by the first brake lever when the first brake lever is operated. The second switch is activated by the second brake lever when the second brake lever is operated. The first electronic brake assembly is connected to the second hydraulic brake assembly. The first electronic brake assembly controls an oil pressure applied to the second brake caliper according to whether the first switch and the second switch are activated.

Abstract: A control method for bicycle anti-lock brake device includes determining whether a wheel deceleration of the bicycle is larger than or equal to a deceleration threshold. When the wheel deceleration of the bicycle is determined to be smaller than the deceleration threshold, the anti-lock brake device of the bicycle is inactivated. When the wheel deceleration of the bicycle is determined to be larger than or equal to the deceleration threshold, determining whether a wheel speed of the bicycle is larger than or equal to a wheel speed threshold. When the wheel speed of the bicycle is determined to be larger than or equal to the wheel speed threshold, the anti-lock brake device of the bicycle is activated. when the wheel speed of the bicycle is determined to be smaller than the wheel speed threshold, the anti-lock brake device of the bicycle is inactivated.

Abstract: The disclosure provides an anti-lock brake device including an oil pressure tank, a first piston and a second piston. The oil pressure tank has an internal space, an oil inlet and an oil outlet that are connected to one another. The first piston is slidably located in the internal space, and has a first oil channel penetrating a contact portion of the first piston and connected to the oil inlet. The second piston is slidably located in the internal space and includes a push portion, and an outer diameter of the push portion is smaller than that of the contact portion. When the second piston is in a closed position, a chamber having a first unoccupied volume is formed in the internal space. When the second piston is moved from the closed position to a depressurized position, the first volume of the chamber is increased to a second volume.
