Water drain holes, located through the sidewalls of hollow rims for vehicle wheels not sealed from water ingress, is described herein to provide an egress for accumulated water. The water drain holes in a wheel rim can be for any type of vehicle utilizing a hollow rim design for wheels when not sealed from water ingress. Without drain holes, accumulated water inside a hollow rim adds significant weight, which produces undesirable effects, such as resistance to the vehicle driver input to accelerate, steer, and otherwise control the vehicle, such as but not limited to a bicycle. Also, accumulated water inside a hollow rim enables increased galvanic current conductivity, producing corrosion.

The present invention relates to a bicycle rim structure for easier installation of tape, which includes a rim body and a tape, wherein the tape is a strip wound around an outer side of the rim body, an engagement structure is provided to engage the two end taps overlapped each other, so that the installation of the tape become convenient and quick, and the tape may effectively protect an inner tube to avoid the inner tube being punctured and extend useful life of bicycles. At least a lightening hole is further set on the rim body, and at least a LED set in a corresponding position of the lightening hole on the tape to achieve a light warning effect. By the above composition, the purpose of easier installation of tape and enhancing efficiency in the use may be achieved for product promotion.

A carbon fiber rim comprises a circular rim and a heat conduction layer. The circular rim comprises carbon fiber composites, and has two opposite side surfaces facing two brake pads and two opposite hooks extending outward radially to hold tires. The heat conduction layer is arranged on the side surface of the circular rim for forming a braking region facing the brake pad. The heat conduction layer comprises a porous or mesh heat conduction material. A bicycle including the aforementioned carbon fiber rim and the manufacturing method of the carbon fiber rim are also disclosed here. The carbon fiber rim can prevent distortion due to frictional heat when braking.

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 wheel rim including an outer annular portion adapted to receive a tire and an inner peripheral radial portion that has both a plurality of circumferentially arranged spoke openings and a braking surface on this portion.

A bicycle wheel rim having a circular base portion including a proximal surface and a distal surface, and a pair of integral sidewalls extending generally radially outward from an intersection region of the proximal surface and the distal surface. The distal surface of the rim has a central hump, a trough contiguous with the central hump extending axially outward from the hump, and a flat shelf immediately adjacent, contiguous with, and extending axially outward from the trough. Another embodiment of the invention is directed to a bicycle wheel including the embodied rim, a plurality a spokes engaged at respective ends thereof with the rim and a hub engaged with the plurality of spoke members at opposite ends thereof. Another embodiment of the invention is directed to a bicycle wheel assembly comprising the embodied wheel and a tube and/or tire mounted on the rim.

A wheel for use with a bicycle includes a hub for mounting the wheel to a bicycle. The wheel includes a rim about which a tire is mountable and a plurality of spokes that extend between the hub and the rim. The rim and/or one or more of the spokes have a leading and/or trailing edge, at least part of which has an undulating configuration.

A wheel with flexible spokes, 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.

A bicycle rim comprises a radially outer peripheral part, a radially inner peripheral part, at least one sidewall, and at least one cover member. The at least one side wall radially extends between the radially outer peripheral part and the radially inner peripheral part. The at least one side wall comprises at least one opening. The at least one cover member covers the at least one opening, and the at least one cover member comprises a metallic material.

A manufacturing method and structure of a carbon fiber rim is revealed. A metal strip is formed by heating a metal substrate to a moldable temperature and then extruded molding. The metal strip comprises two side walls, a connecting wall and an inner rim wall to form a space surrounded by the side walls, the connecting wall, and the inner rim wall. Next, two terminals of the strip are connected to form a circle as a rim frame's embryo. The two side walls, or the two side walls and the inner rim wall of the rim frame's embryo are milled to form plural through holes and become a rim frame. Afterwards, the surface of the rim frame is roughened and covered with a trimmed carbon fiber cloth having a predetermined shape. After heatsetting and surface treating, a carbon fiber rim having a light weight and a strong structure is obtained.
