This disclosure provides an oil brake device for use in the bicycle in which a saddle support is resiliently suspended independent of a main body frame so as to prevent the transmission of shock and vibrations of front and rear wheels in bicycle riding. The brake device is designed to prevent sharp elevation of the saddle support when the bicycle is stopped, or sharp downward movement of the support when starting from the halted position. The device works in cooperation with the wheel brake.
