A quick release apparatus for a bicycle tire or tube is provided, which reduces time and effort spent in changing the tire or tube. A main wheel frame and a sub wheel frame are provided. These two frames with rim respectively can be assembled to construct a complete wheel frame set. When said main wheel frame connects with the sub wheel frame, it provides a complete rim with two walls for containing the tube. When said main wheel frame leaves said sub wheel frame, it generates a gap between these two frames for removing the tube easily.

Systems and methods disclosed herein may be useful for use in a wheel assembly. In this regard a wheel assembly may comprise a wheel base with a center axis, a side rim disposed about a circumference of the wheel base, wherein the side rim includes a frustoconical radially inward surface, and a lock ring comprising a single unitary member. The lock ring may secure the side rim onto the wheel base, the lock ring preventing the side rim from sliding axially with respect to the wheel base, wherein a frustoconical radially outward surface of the lock ring comprises a first angle with respect to the frustoconical radially inward surface of the side rim.

Aircraft wheel rim in two parts, one of them a main part (1) comprising a hub (2), a disc (4) extending between the hub and an annular external portion (3) intended to accept a tire and shaped to have a flange (5) at one of its ends. The other end is shaped to accept the second part, a removable part (10) forming a flange (12) which removable part is attached to the annular external portion after the tire has been fitted. The rim has a structure for preventing the removable flange from rotating relative to the rim. The structure comprises at least one link (20) having ends, the centers of which define an axis which extends in a plane perpendicular to an axis of rotation of the rim while at the same time extending obliquely to make an angle () with respect to a radial direction, one of the ends being coupled to the main part and the other of its ends being coupled to the removable part.

A wheel for a pneumatic tire has a rim with one monolithic bead seat and a removable beat seat. The removable bead seat has two halves that embrace the rim and engage a groove to retain the tire. The removable bead seat may have a second lip either monolithically formed or as a part of a separate retainer that bolts to the bead seat. The wheel may be made from aluminum alloy.

A method of coupling a tire to a wheel is disclosed. A bead of the tire is placed against a side rim that is movable with respect to the wheel base. The side rim is moved along the axis of the wheel base and against the tire bead to couple the tire to the wheel.
