The present invention is directed to airless tires. Exemplary airless tires include a hub configured for attachment to an axle and includes a hub support extending away from the hub. Such exemplary airless tires also include a heel configured around the hub and connected at a distal end of the hub support, whereby the heel includes an elastomer base oriented in a ring around a circumference of the hub support. Such exemplary airless tires also include elastomeric tubes extending radially outward from the heel. Other exemplary airless tires include a centerless hub assembly configured for attachment to an axle and a heel configured around the centerless hub assembly. The heel in such exemplary airless tires includes an elastomer base oriented in a ring around a circumference of the centerless hub assembly. These other exemplary airless tires include elastomeric tubes extending radially outward from the heel.

A rim portion of a composite wheel comprises a shaped annulus formed about a central axis of rotation of the composite wheel and having a circumferential axis extending circumferentially about the central axis and around the rim portion, said rim portion having a fibre layup comprising a stacked laminate formed from alternating layers of: a hoop tow layer comprising elongate fibre tow in which the fibres are substantially aligned with the circumferential axis of the rim portion, the hoop tow layer being formed from at least one annularly wound elongate fibre tow; and a bias ply layer comprising at least one fibre ply in which the fibres are substantially orientated at an angle of + or to the circumferential axis of the rim portion, wherein is from 26 to 40.

Embodiments described herein provide aerodynamic bicycle rims and wheels. Embodiments can include a bicycle rim that is wider than the width of the tire proximate to the outer edge of the rim and is shaped so that there is a tangent line tangent to the rim and the tire. The tangent line can be tangent to the rim on the sidewall or elsewhere on the rim. The widest part of the rim can be radially inward from the outer edge of the rim or elsewhere on the rim and the tangent line can be tangent at the widest part of the rim or elsewhere on the rim.

An apparatus for reducing tire noise may include a rim with a tire mounted thereto in a wheel; a resonance tube provided along an external circumferential surface of the rim, and configured such that a first edge portion thereof in a width direction is provided with a first flange locked to a first side wall of the rim and a second edge portion thereof in the width direction is provided with a second flange; a strap provided along the external circumferential surface of the rim to surround the second flange of the resonance tube such that the resonance tube is brought into contact with the external circumferential surface of the rim; and a protruding portion configured to protrude from the external circumferential surface of the rim to prevent the resonance tube and the strap from being moved in the width direction thereof.

The present invention relates to an in-wheel motor. The in-wheel motor according to an embodiment of the present invention includes: a circular rim to which a tire is coupled by being wrapped around an outer ring thereof and a shaft is connected by passing through a center thereof; a motor assembly which is disposed in an inner portion of the rim and includes a stator connected to the shaft and a rotor disposed to be wrapped around the stator and configured to rotate; a cover coupled to cover one open side surface of the rim and configured to seal the inner portion of the rim; and a lead-out wire entry/exit portion waterproof structure configured to seal an entry/exit portion for a lead-out wire connected to supply power from outside of the in-wheel motor to the inner portion of the rim via a hollow portion of the shaft, wherein the lead-out wire entry/exit portion waterproof structure includes an elastic stopper, to which the lead-out wire is connected to pass through a center thereof and which is configured to be elastically contracted after being inserted into the hollow portion of the shaft in an axial direction and seal between the hollow portion of the shaft and the lead-out wire, and a stopper fixing body fastened to the shaft and configured to press the elastic stopper in the axial direction so that the elastic stopper is inserted and fixed inside the hollow portion of the shaft.

A pneumatic tyre comprises a tread portion, a pair of opposing sidewall portions and a pair of opposing bead portions, the tread portion extending radially outwards from the sidewall portions and the sidewall portions extending radially outwards from the bead portions, wherein each bead portion comprises an axially inward side and an axially outward side which are joined at a base of the bead portion and each axially outward side of the bead portion comprises a concave region extending axially inwards. Each concave region further comprises a convex region located within the concave region which extends axially outwards.

Bicycle rims that allow tires to be more easily mounted in a tubeless configuration are disclosed. More specifically, a bicycle rim may control the two beads of the tire with separate bead channels for each bead and a center bridge extending between the two bead channels.
