A low-speed vehicle wheel assembly includes a rim, at least three spokes, connectors, a central bearing seat, and bearings. Outer ends of the spokes are fixedly connected to an inner side wall of the rim through the connectors, respectively. Inner ends of the spokes are fixedly connected to an outer wall of the central bearing seat. The bearings are fitted in bearing holes of the central bearing seat, respectively. Because the rim and the central bearing seat are independent components, each component can be made with an independent mold and assembled according to the diameter of the wheel. The cost of the mold is lower, and the components are more versatile.

A bicycle rim for carrying a tire. The rim includes a circumferential tire bed including first and second opposing edge regions a circumferential spoke face, and first and second side walls extending from the spoke face to the first and second edge regions, respectively. The first and second side walls include first and second side wall extensions radially extending from the first and second opposing side regions and terminating at first and second outer radial edges, respectively. Each of the first and second outer radial edges defining a maximum width that is at least 3.8 mm. The thickness of the first and second side wall extensions varies with respect to a central radial axis. The thickness of the first and second side wall extensions is greater at the first and second outer radial edges than at a location radially spaced from the first and second outer radial edges and adjacent to the first and second opposing end regions, respectively.

A wheel is provided for a motor vehicle. The wheel includes a hub, a rim and a plurality of spokes that extend between the hub and the rim. At least one of the spokes includes an integral step having a slip resistant surface.

A thermal treatment and shot peening method for a wheel, including: heating a wheel blank to T1, and preserving the heat for t1; fast heating the wheel blank to T2, and preserving the heat for t2; performing quenching treatment, wherein a quenching medium is at temperature of T3, and the quenching transfer time is t3; performing aging treatment at aging temperature of T4, and preserving the heat for t4; performing first-stage shot peening; and performing second-stage shot peening.

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 longitudinally tapered wheel spoke having a thin aerodynamic cross-sectional profile proximate to the wheel rim and tapering to a round profile toward the central hub, with the tapered section optimized to minimize drag against a combined headwind and crosswind impinging upon the primary vehicle-drag-inducing uppermost region of the wheel assembly.

A bicycle real wheel hub includes pulling spokes and static spokes connected to the disks thereof. The hub includes a tubular portion with two disks respectively connected to two ends of the tubular portion. Multiple protrusions protrude from the inner side of each disk. The head of each pulling spoke is secured to the protrusion corresponding thereto. The head of each static spoke is secured to the disks. The heads of the pulling spokes are located closer to the middle point of the tubular portion than the heads of the static spokes. When the hub rotates, the static spokes provide strength in the axial direction of the hub, and the pulling spokes have strong tension so that the hub bears higher torque.

Methods for wirelessly communicating with vehicle adapted to be at least partially powered by a human are disclosed. An example method may include transmitting data from a device remote from the vehicle and configured to communicate with the vehicle, receiving the data at the vehicle, and configuring a parameter of the vehicle based on the data.
