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.

A wheel includes a first hoop attached to a second hoop about a circumferential interface. The first and second hoops form at least part of an enclosed box structure positioned circumferentially around the wheel and adjacent to an outboard side of the wheel. The box structure may be formed at least in part by circumferential projections of the first hoop and the second hoop. The wheel may also include a central hub that optionally includes spokes. In some embodiments, the central hub may form part of the enclosed box structure. In some embodiments, a first hoop portion and a second hoop portion may be integral or unitary, with a box structure integrally formed between the hoop portions.

A wheel includes a rim that is at least partially made from a fiber reinforced plastic. The rim has an inner side extending to the hub region of the wheel and an outer side extending centrifugally away from the hub region of the wheel whereby the outer side includes a well which is interconnected with an outer shoulder by a transition area. A wheel center is interconnected with the inner side of the rim by at least one fastener wherein the at least one fastener penetrates the rim via at least one opening that extends from the inner side of the rim to the outer side of the rim. An annular cover is arranged at the outer side of the rim in a circumferential direction around the wheel and thereby covers the at least one fastener and/or the at least one opening.

An assembled wheel includes a spoke, a T nut, a screw, a fixing ring, a rim, a brake drum. In use, the T nut is installed in the outermost T groove of the spoke; a second boss on a connecting ring fits with the groove on the back of the spoke; the spoke, the connecting ring and the fixing ring are connected together by the first screw; grooves on the outer side of the brake drum fit with a first boss in the right circumferential direction of the fixing ring; and the second screw axially fixes the brake drum in the fixing ring through a spacer.

An apparatus for measuring a speed of a vehicle having an in-wheel motor including a lock nut part fixed to an outer portion of a rotation shaft rotated by receiving power of the in-wheel motor, and restricting movement of a bearing part positioned outside the rotation shaft; a connection part coupled to the lock nut part; a magnet part having a magnetic force, and fixed to the connection part; and a speed sensor part installed to be separated from the magnet part, and measuring rotations of the magnet part.

An improved clamping mechanism to secure a tire between a bead ring and a wheel utilizing a bolt is provided. The bolt has a ball seat that pivots within an enlarged pilot hole in the bead ring as the bolt threads engage in threaded section of the wheel, pulling the bead ring toward the wheel. As the bead ring is tightened upon the wheel, eventually the bead ring contacts a fulcrum on the wheel, at which point the outer edge of the bead ring is leveraged against the tire bead bundle and pressing down the tire bead to lock it in place against the wheel. As the bead ring can pivot within the enlarged pilot hole around the bolt, the bolt is not stressed. Further, the wheel comprising a safety bead and non-skid coating on the inner wall of the wheel to prevent the wheel sliding around the wheel.
