  • Publication number: 20220226691
    Abstract: An integrated operating device has a brake mechanism having a brake cable, a resistance mechanism having a resistance cable, and an operating mechanism. The operating mechanism has a pivoting disk and an operating rod. The pivoting disk is pivotally mounted on a bike frame. An end of the resistance cable is connected to an edge of the pivoting disk. When the pivoting disk pivots, the resistance cable is winded around an outer annular surface of the pivoting disk. The operating rod is pivotally connected to the pivoting disk, is capable of turning the pivoting disk, and has a hook segment. The hook segment is connected to the brake cable. When the operating rod pivots relative to the pivoting disk, the hook segment moves to tighten or to release the brake cable. By this, the integrated operating device is capable of controlling the resistance mechanism and the brake mechanism with one operating rod.
