Abstract
A wheel comprises a sheet metal rim of radially outwardly open, generally U-shaped cross-section, a central portion extending around a hub and a plurality of spoke portions extending radially outwardly from the central portion to the rim. Each of the spoke portions is of sheet metal and has a closed, hollow transverse cross-section. Curved metal strips contiguous with the inner periphery of the rim are secured within the radially outermost ends of the spoke portions, and releasable fasteners secure the rim to the curved metal strips. This wheel is of rugged construction, the rim being readily replaceable, and obviates the adjustment of multiple wire spokes required in conventional bicycle wheels.
