An article includes having a braided fiber having a first end and a second end, and a rod having a first end and a second end, whereby the first end of the rod is threaded and wherein the second end of the rod is disposed inside the first end of the braided fiber.

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.

A stable, low-weight wheel which is particularly suitable for high system-weight bicycles, such as electrically powered bicycles and cargo bikes, includes a hub, at least three solid-body spokes disposed rotationally symmetrical to the wheel axis, and a rim. The body of the hub, spokes and rim is made in one piece by injection molding of a glass-fiber reinforced thermoplastic. The spokes have an S-shaped cross-section with an opening angle which increases in the direction of the rim, taper from the rim towards the hub in a central cross-section of the wheel, and taper from the hub towards the rim in a wheel cross-section running through the center of least one spoke. A method for producing the wheel is also provided.

A wheel with high strength flexible spokes of the present invention, including a rim and hub, and spokes between the rim and hub made of fibrous material that causes the spokes to be both lighter in weight and stronger than comparable steel spokes. The spokes are also flexible and resilient such that they can bend while retaining their integrity and strength. The wheel includes a nipple within the rim that receives the high strength spoke and allows for flexibility in adapting the spoke to wheels having differing shapes and sizes.

A bicycle frame system comprises a connection module that rotatably connects a front frame section to a rear frame section. The connection module comprises a hinge section and a clamp section. The hinge section is below the clamp section when the bicycle frame system is in a ridable orientation. The connection module hinge section has a horizontal axis of rotation configured for rotating a front bicycle frame section approximately 180 degrees downwards and rearwards relative to a rear bicycle same frame section to convert the bicycle frame system from a ridable configuration to a folded configuration. The connection module clamp section comprises a front clamp block, a rear clamp block and a fastening device. The fastening device is configured to secure the front clamp block to the rear clamp block when the bicycle frame system is in a ridable configuration. The interface between the front clamp block and the rear clamp block comprises at least one v-shaped feature configured to prevent the front clamp block from moving laterally relative to the rear clamp block when the front clamp block is pressed against the rear clamp block.

A wheel for a two wheeled vehicle including a flange and a plurality of spokes, the spokes connecting the rim to the flange, wherein brake force spokes of the plurality of spokes are stronger than drive force spokes of the plurality of spokes. In one alternative, the flange has an inner and an outer area.

A power generation system is provided configured for installation within a wheel of a vehicle. The system includes a stator having a plurality of face-mounted permanent magnets; and a rotor having a plurality of windings configured to rotate, with rotation of the wheel, in proximity to the permanent magnets thereby generating a current. The stator is mounted to a brake caliper of the vehicle. Also provided is a wheel-based vehicle display system including a light emitting diode (LED) array arranged on or within a wheel of a vehicle; a power source connected thereto; and a controller connected to the LED array. The display system is configured to display at least one of: textual information, visual images or full-motion video.

A bicycle disc or spider wheel including: a hub; a rim having a radially outer tire-coupling region, a first sidewall, a second sidewall; an axis of rotation; and a median plane. A pair of pretensioned disc or spider wheel-type structural elements are integral with the hub and with the rim. The first sidewall extends on a first side of the wheel, with respect to the median plane, on which a component of a motion transmission system or, when there is none, a disc of a disc brake is provided at the hub, and the second sidewall extends on the opposite side, with respect to the median plane. The first sidewall of the rim has a minimum distance from the median plane that is smaller than that of the second sidewall of the rim.
