The present disclosure discloses a carbon fiber bicycle rim and a manufacturing method thereof. The carbon fiber bicycle rim comprises a ring-shaped rim body, which is integrally formed from carbon fiber. The rim body comprises an outer ring wall, an inner ring wall, and two side walls that connect the outer ring wall with the inner ring wall. The outer ring wall has an outer side that forms a semi-closed tire groove and an inner side that encloses together with the inner ring wall and the side walls to form a closed cavity. Connecting portions are arranged in the cavity. The connecting portions have one end that is connected to the outer ring wall and the other end that is connected to the side walls. The connecting portions enclose together with the outer ring wall and the side walls to form hollow channels.

The present invention is directed to a non-pneumatic tire comprising a circumferential tread band, spokes arranged radially inwards the tread band, and anchoring rails extending in an axial direction and attached to a radially inner side of the tread band along the circumferential direction. The spokes are slidably mountable to the anchoring rails in the axial direction, connecting the tread band and the spokes by mechanical interlocking. Furthermore, the present invention is directed to a non-pneumatic tire comprising on a radially inner side of a tread band axially extending anchoring portions, and two axially neighboring rows of X-shaped spokes, which are circumferentially shifted relative to each other so that each anchoring portion anchors a radially outer right leg of a spoke in a first row of the axially neighboring rows and a radially outer left leg of a spoke in a second row of neighboring rows of spokes.

A wheel for a vehicle comprises a rim to support a tire and a wheel disc connected to the rim and configured to engage an axle hub of a vehicle. The wheel disc comprises one or more spokes extending outwardly from a center section of the wheel disc to the rim, each spoke being formed by a substantially planar curbside spoke member and a substantially planar inside spoke member, The curbside and inside spoke members are oriented transversely to each other and to a portion of the center section lying between the curbside and inside spoke members to define a triangle. A plane of the triangle is substantially parallel to a center axis of symmetry of the disc.
