To provide a bicycle hub unit and a bicycle wheel assembly that allow a wheel unit to be appropriately coupled to a hub body, a bicycle hub unit is coupled to a rotary body to which a brake is applied by a brake device. The bicycle hub unit includes a hub body that rotates around a hub axle and a rotary body coupling portion that couples the rotary body to the hub body. The hub body includes a first joint portion and a second joint portion. The first joint portion includes an external thread coupled to an internal thread of the wheel unit. The second joint portion is coupled to a restriction member that restricts relative rotation of the first joint portion and the wheel unit.

A lightweight wheel with high strength flexible spokes of the present invention, includes a rim and hub, and a plurality of lightweight, flexible and resilient 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 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.

The present invention discloses a carbon fiber spoke and a manufacturing method thereof. The carbon fiber spoke includes a spoke body made of carbon fiber, a screw bushing that is fit and connected with rim and a nut cap bushing that is fit and connected with the hub. Two end parts of the spoke body are provided with solid joints. The outside surface of the solid joint is provided with a first tapered section. The screw bushing and the nut cap bushing are provided with penetrable mounting holes. The hole wall surrounding the mounting hole is provided with a second tapered section. The mounting hole of the screw bushing and the mounting hole of the nut cap bushing are respectively fixed to the two solid joints; the second tapered section of the mounting hole and the first tapered section of the solid joint are fit and connected together.

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 vehicular wheel assembly defines an axis of rotation and includes a wheel having an inner hub, an outer rim, and a plurality of hollow spokes. The outer rim defines an outer circumference. Each hollow spoke of the plurality of hollow spokes extends between the inner hub and the outer rim and includes a wall that at least partially defines a hollow chamber. The outer rim defines a plurality of openings that are each in fluid communication with one of the hollow chambers and each of the openings includes a tuning member.

A human-powered vehicle wheel unit adapted to be attached to a human-powered vehicle hub. The wheel unit includes an accommodation portion and a first engagement portion. The accommodation portion is configured to accommodate at least part of the human-powered vehicle hub. The first engagement portion is provided on the accommodation portion. The first engagement portion is configured to transmit rotation of the human-powered vehicle hub to the accommodation portion through engagement with a second engagement portion provided on a flange projecting from an outer circumferential portion of a hub shell of the human-powered vehicle hub.

A tensile element connection, comprising first and second bracing elements and a tensile element having a first portion connected to the first bracing element and a second portion opposed to the first portion and connected to the second bracing element, and an applied tensile load along the tensile element. The tensile element includes a preformed rod that is comprised of reinforcement fibers in a matrix. At a temporarily elevated temperature greater than the service temperature, a localized region of the matrix is in a softened state of increased deformability such that a localized region of the rod is deformed under pressure to include a laterally outwardly projecting engagement surface. The tensile element is comprised of said rod with the engagement surface formed therein and is connected to one of the first and second bracing elements by means of an overlie engagement at the engagement surface to restrain the tension load.

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 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 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.
