ABSTRACT:
A wheel for lessening rolling resistance and other forces that retard the rolling of the wheel consisting of a circular wheel rim, a hub member positioned concentrically within the wheel rim and a spoke arrangement connecting the wheel rim with the hub member for storing and releasing externally applied energy to provide propulsive torque to the wheel. The spoke arrangement is formed from a single strand of wire that is wound around the hub and is extended to the rim to form spoke loop portions. As the wheel is rolled over a supporting surface, each spoke loop portion is flexed as the portion of the wheel adjacent thereto engages the roadway. As that portion of the wheel approaches a point where it breaks contact with the roadway the spoke portion closest thereto unflexes imparting a torque on the wheel in the direction in which it is being rolled.
