US Patent 7445034 Bicycle wheel without an inner tire

A bicycle wheel includes a wheel rim, a lining strap, and a tire. Thus, each of the edges of the lining strap is clamped in the clamping space of the respective clamping hook of the wheel rim and closely retained by the respective clamping hook of the wheel rim and the respective sidewall of the opening, and the protruding lips of the tire are movable freely on the smooth face of the lining strap, so that when the tire is subjected to an external force, the lining strap will not driven by the tire to prevent a gap from forming between the lining strap and the tire and to prevent the air contained in the tire from leaking from the mounting holes of the wheel rim.
