Abstract: A scooter wheel assembly consists of a rim which holds a tire and said rim having as its axial hole two tapers meeting at its mid-plane. The rim accepts two hub halves of which each is a frustum, such that clamping forces across the opposed conical surfaces of the pair of frusta firmly enforce concentricity between the axle and the rim and its tire. The rim and tire are connected to the axle exclusively by frictional coupling. Advantageously for changing a rim or tire, the hub parts can be quickly disassembled with common tools.
