This patent is on a flywheel apparatus which includes a pair of radially extending diametrically opposed spokes with a rim mounted theoreon. The rim is elliptical with the major axis being substantially coextensive with the longitudinal axis of the spokes. The difference in length between the major and minor axes is such that when the flywheel is at full speed the rim is substantially circular. With this arrangement contact and low stress are maintained between the rim and the spokes when the flywheel apparatus is at full speed.
