A bicycle wheel has a wheel frame. The wheel frame is a hollow and annular frame and is composited by multiple equally sized wheel bars. Each one of the wheel bars has two halves connected to each other to form the wheel bar, and each one of the two halves being made by laminating, heating and forming a thermoplastic prepreg. The equally sized wheel bars are connected to each other to form the bicycle wheel.

A nipple for spoked wheels includes a head and a rod which are coaxial and through which a through-hole extends, a manoeuvring key in the head and an insert of plastics material which is inserted in the hole in order to engage in a screwing manner with friction with a threaded end of a spoke. The hole comprises a threaded portion which extends in the rod and a portion with an increased diameter which constitutes the seat for receiving the insert, the insert being formed with a tubular sleeve inserted in the seat at the side of the head and being blocked there by means of interference or adhesive bonding.

A wheel for use with a bicycle includes a hub for mounting the wheel to a bicycle, 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 rim for a bicycle wheel includes a radially outer tire-engaging portion, a first sidewall, and a second sidewall spaced apart from the first sidewall. The first and second sidewalls may extend radially inward of the radially outer tire-engaging portion. The rim includes a radially inner portion having at least one asymmetric protrusion.

A spoke wheel includes a light alloy rim, a hub, and a plurality of wire spokes connecting the rim with the hub. The rim includes mounting flanges provided at asymmetrical positions with respect to a widthwise center of the rim and is connected with the hub by assembling the spokes to the mounting flanges. The spokes are disposed by being offset to the widthwise center of the rim.

A kit for a wheel comprises a hub component in the form of an annular body defining a central opening for receiving a shaft on which the wheel is to be mounted, at least one outer rim component adapted to form a substantially circular periphery of the wheel and a plurality of spoke components adapted to interconnect the at least one outer rim component and the hub component with each of the spoke components being arranged at a respective angular position about the hub component. Each outer rim component is formable from a blank comprises a main body which defines an outer ground engaging surface of the wheel, a pair of strips consecutively attached to one end of the main body in a manner such that each strip is movable relative to the adjacent element about a transverse folding axis, so that the strips can be folded to define a peak projecting outwardly to form a wheel rim with fins.

A wheel suspension system, comprising, a wheel rim, a plurality of adaptors equidistantly mounted on inner periphery of the wheel rim, a plurality of suspension curved elastic members having drafted ends configured to be circumferentially and linearly disposed into the adaptor along the wheel rim, and a multi-layered hub having a plurality of interlocked holders away from its centre towards the wheel rim for interlocking the elastic members at the centre. The wheel suspension system is cost effective for both users and manufacturers, user friendly, comfortable, easy to assemble or disassemble, comfortable and provides safety in cases of accidents.
