The hydraulic engine includes a rotatable spindle, and a coupling device coupled between the spindle of the hydraulic engine and the hub shell, to allow the hub shell to be driven or rotated by the hydraulic engine. A plate and a casing are rotatably received in the hub shell, to rotatably support the hydraulic engine in the hub shell with the plate and the casing. A directional control device may be used to control rotational movements between the spindle of the hydraulic engine and the hub shell.
