The disclosure provides a wheel, drive wheel and wheel chair. The wheel includes an annular rim and a disk covering the rim on one side in an axial direction of the rim. The disk of the wheel includes a skin and a cushion member. The skin is formed of a fiber-reinforced material. The cushion member includes a cushion part and a shape retaining part. The cushion part is formed of a shock absorbing material and is disposed adjacent to the skin. The shape retaining part is formed of a fiber-reinforced material and is disposed adjacent to the cushion part.

A wheel disc adapted for use in a fabricated vehicle wheel includes a steel wheel disc defining an axis and includes a center mounting portion, an outer rim connecting flange, a plurality of radially outwardly extending spokes connecting the center mounting portion to the outer rim connecting flange and a ventilation opening provided between each pair of adjacent spokes. A width defined by a center wall of the spoke is tapered inwardly along a substantial portion of a radial length thereof as the center wall of the spoke extends generally from the center mounting portion to the outer rim connecting flange or wherein a width defined by outer walls of the spoke is tapered inwardly along a substantial portion of a radial length thereof as the outer walls of the spoke extends generally from the center mounting portion to the outer rim connecting flange.

A bicycle disc wheel comprises a first disc panel and a second disc panel. The first disc panel has a first side outer surface and a first side inner surface and the second disc panel has a second side outer surface and a second side inner surface. The first side outer surface radially extends from a first disc panel outer perimeter to a center opening and the second side outer surface radially extends from a second disc panel outer perimeter to the center opening. The second side inner surface faces the first side inner surface. A brace is coupled to the first side inner surface and the second side inner surface that provide radial and axial structural support to the disc panels.

A disk wheel for a motor vehicle, in particular a single-track motor vehicle, includes: a wheel hub for mounting the disk wheel on the motor vehicle, which wheel hub is concentric to an axis of rotation of the disk wheel; a wheel rim, which is likewise concentric thereto; and a first and a second wheel disk. The first wheel disk and the second wheel disk each extend from the wheel rim toward the wheel hub, are mutually spaced on the wheel hub in a transverse direction which is parallel to the axis of rotation of the disk wheel, and run toward each other as they approach the wheel hub. The disk wheel also has at least two reinforcement ribs, which extend from the first wheel disk to the second wheel disk and interconnect the first wheel disk and the second wheel disk. The reinforcement ribs are distributed evenly around the axis of rotation of the disk wheel.
