ABSTRACT OF THE DISCLOSURE The hub of a spoke-wheel such as spoke-wheel for a wheelchair is produced by injection molding such that the central tubular part of the hub and the end flanges are injection molded from a suitable plastic material. The openings for retaining the ends of associated spokes are then machined, cut out or molten away in a subsequent step. Preferably, the hub is produced from two halves interconnected at the center of the tubular central part. The advantage is in that no expensive injection molding tools are required such as those used in regular bicycle wheels which normally do not require considerations of axial pressures to which the hub is exposed quite frequently in the case of a wheelchair or the like.
