A wheel assembly, including a rim and a central hub assembly, having a plurality of spokes threaded to a central hub. Each of the spokes movable under spring load within a tangential slots provided on the rim. A spring surrounding each spoke, with a first end of the spring engaging the central hub. When the wheel assembly is rolling and encounters a force caused by a bump and the rim deflects radially, the rim moves radially, causing the slots to move radially and tangentially along the spokes while the springs absorb the impact caused by the bump.
