The coefficient cycling aero foil system is designed to reduce drag and turbulence from a tire and spokes used to support a bicycle wheel. The system is integrated into a rim on a bicycle wheel which allows for increased forward momentum by cutting drag and reducing wheel turbulence that occurs during the rotation of a bicycle wheel. The foils may be strategically placed for optimum aerodynamic wind flow and are precisely angled to force wind past the foil creating increased forward momentum.

The present disclosure relates to a rim for a wheel. In one aspect, there is provided a rim for a wheel. The wheel comprising a rim, spokes, and hub. The rim depth varies wherein the section approximately half way between spoke connection points to the rim is of the greatest depth. Further, the section of rim located between the spoke connection point to the rim and the centre-point of the rim between spokes is of the shallowest depth. The spokes being of the type to provide support under forces of compression and tension. In a further aspect, there is provided a wheel comprising the rim.

A wind-diverting apparatus for minimally shielding only the faster-moving drag-sensitive uppermost wheel surfaces from headwinds reduces overall vehicle drag. The apparatus includes various upper wheel fairings of FIGS. 1-6. Each fairing shields a primary vehicle-drag-inducing upper wheel surface from headwinds otherwise impinging directly thereon.

A pedal driven cycle comprising a cantilevered frame member coupled to a power input sprocket and a driven sprocket; a belt drive connecting the power input sprocket to the driven sprocket; and a side mounted rear wheel releasably coupled to a multi-speed gear hub that is coaxial with the side mounted rear wheel, wherein the multi-speed gear hub is coupled to the driven sprocket.

The invention relates to a stable one piece wheel, which is particularly suitable for cycles having an increased system weight such as electrically powered bicycles or cargo bikes, and a method producing said vehicle wheel. Said vehicle wheel comprises an annular portion (110), a plurality of spokes (120) and a hub portion (130) integrally formed by mould injection of fibre reinforced or carbo nano tubes containing thermoplastic, wherein each of the plurality of spokes (120) comprise a substantially Z-shaped cross section with a middle leg (122) and a pair of outer legs (121, 123), wherein the angle (γ) enclosed by each of the pair of outer legs and the middle leg is greater than a right angle and wherein the length of the middle leg (122) increases from the annular portion (110) toward the hub portion (130).

The present invention relates to a vehicle (100), in particular a bicycle, for performing tests for a driver assistance system. The vehicle (100) has a base body (101) and at least one strut (102), which is formed to be dimensionally stable without influence of an impact force, which is generatable upon a collision of the vehicle (100) with a collision body, and is elastically deformable upon influence of the impact force. The strut (102) is connected to the base body (101) such that upon influence of the impact force the strut (102) is non-destructively detachable from the base body (101).

A bicycle disc wheel comprises a first disc panel and a second disc panel. The first disc panel has a first side outer surface and a first side inner surface and the second disc panel has a second side outer surface and a second side inner surface. The first side outer surface radially extends from a first disc panel outer perimeter to a center opening and the second side outer surface radially extends from a second disc panel outer perimeter to the center opening. The second side inner surface faces the first side inner surface. A brace is coupled to the first side inner surface and the second side inner surface that provide radial and axial structural support to the disc panels.

A marked wheel rim is provided, including: a rim body and a mark. The rim body includes an outer surface. The mark is embedded on the outer surface and includes an outer peripheral edge adjacent to the rim body. The outer peripheral edge is non-protrusive beyond the outer surface. A method for manufacturing the marked wheel rim is further provided.

Disclosed is an illumination device for use with spoked wheels, such as bicycle wheels, wherein the wheel includes a hub portion, a plurality of spokes, and a rim portion. The illumination device includes a power pack, at least one adaptor body, and at least one attachment portion. The power pack having at least one wire, a flexible button cap, a body housing, and circuit board with a switch. The at least one wire including a plurality of light sources. The at least one attachment portion including a clip portion providing for the installation of the at least one adaptor body to the bicycle spokes. The illumination device also includes a holder for the installation of the power pack to the bicycle wheel. Further, the illumination device may include a tubular body located in the internal cavity of the at least one adaptor body.

A streamlined tailfin pivotably attached to a shaft-shaped member disposed on a vehicle provides for reduced drag in winds varying in direction impinging thereon.
