A spoke attachment flange for a bicycle wheel hub is disclosed. The flange has a plurality of seats for housing enlarged spoke heads. Each spoke seat has an access hole that allows the insertion of the enlarged spoke head and an outlet opening that holds the enlarged spoke head when the spoke is tensioned. The access hole and the outlet opening are spaced circumferentially and connected through a connection channel so that an abutment surface abuts the enlarged head and prevents the enlarged head from exiting through the outlet opening. Methods for manufacturing the hub and mounting a spoke on the flange are also disclosed.

A spoke attachment flange for a bicycle wheel hub and a method for mounting spokes on the flange are disclosed. The flange has an annular body with a plurality of seats for housing enlarged spoke heads. At least one seat has an access opening configured to allow the insertion of the enlarged head in the seat. An outlet opening on the annular body is configured to allow a stem of the spoke to exit from the seat. The access opening and the outlet opening are connected through a connection channel that extends from the access opening towards the outlet opening without reaching a radially outer surface.

A hub and spoke assembly includes a hub body having a first end and a second end. Projections are on each end. The projections are spaced apart from each adjacent projection about a rotational axis of the hub. Each projection comprises a base portion joined to the hub body and a support extending from the base portion to a free end. A plurality of spokes is provided. Each spoke comprises an elongated braided fiber having a loop at a first end and a second end configured for attachment to a rim. At least one spoke is joined to each support of each projection.

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.

The present disclosure relates to a hub apparatus and associated charging systems. In some embodiments, the hub apparatus includes (1) a housing assembly defining an internal space; (2) a shaft positioned to extend through the housing assembly; (3) a stator assembly fixedly coupled to the shaft; (4) a side cover fixedly coupled to the shaft and rotatably coupled to the housing assembly, the side cover having a base portion and a mating portion extending from the base portion; and (5) a pair of first connectors positioned through the mating portion. Each of the first connectors comprising a terminal end and a contact portion. The terminal end is electrically coupled to a battery assembly via a wire bundle fixedly coupled to the side cover. The contact portion is configured to electrically couple to an external power source so as to charge the battery assembly through a wired connection.

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.

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 nipple assembly for a spoke wheel according to the present disclosure is coupled to at least one end of a spoke provided on a spoke wheel and includes a main body including a nipple head, and a column portion having a smaller diameter than the nipple head and elongated from the nipple head toward one side, a nipple base having a first through-hole and fitted with the column portion through the first through-hole, and a vibration attenuation member having a second through-hole and positioned between the nipple head and the nipple base by being fitted with the column portion through the second through-hole.

A bicycle hub assembly comprises a hub axle, a hub body, and a sprocket support body. The hub body includes a first spoke-mounting portion, a second spoke-mounting portion, and a first axial length. The first axial length is defined between a first axially outermost part of the first spoke-mounting portion and a second axially outermost part of the second spoke-mounting portion in an axial direction with respect to a rotational center axis. The first axial length is equal to or larger than 55 mm. The sprocket support body is rotatably mounted on the hub axle about the rotational center axis. The sprocket support body includes at least ten external spline teeth configured to engage with a bicycle rear sprocket assembly. Each of the at least ten external spline teeth has an external-spline driving surface and an external-spline non-driving surface.

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.
