The present invention provides a non-pneumatic tire including an inner tube (6) attachable to an axle (15a), an outer tube (4) configured to surround the inner tube from an outer side in a tire radial direction, and an elastically deformable connecting member (3) configured to connect the inner tube and the outer tube to each other, the non-pneumatic tire including at least one of a detection section configured to detect occurrences of scratching, damage, or deterioration in the non-pneumatic tire; and a reporting section (33) configured to report occurrences of scratching, damage, or deterioration in the non-pneumatic tire.

A bicycle rim and/or wheel are provided. The bicycle rim and/or wheel includes a single wall formed into the bicycle rim. The wall is formed of composite material having a spoke attachment portion and a tire attachment portion formed therein. The composite material may include at least two different materials, or fibers used as reinforcement material, forming layers of a thickness of the rim.

A wheel for a bicycle, or other human powerable vehicle, has a hub that includes: (a) an axle for attachment to a bicycle frame; (b) a set of bearings that connect the axle to a rotating sleeve; and (c) at least three connection points fixedly connected to the rotating sleeve. The connection points are used to detachably attach an annular module to the hub using attachment elements that each comprise conical frustum surfaces. The attachment elements are configured to axially press a portion of the hub to a portion of the annular module, as well as radially aligning the hub to the annular module. The annular module also has a set of spoke attachment points configured for tensioned spokes that connect the annular module to a wheel rim. The spoke attachment points are in a circular configuration on two parallel offset planes that are perpendicular to the axis of rotation of the rim.

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 spoke star is made of a fiber-reinforced plastic and formed as a star-shaped closed ring, the spoke star having spokes between a hub-side inner circumference of the spoke star and a rim-side outer circumference of the spoke star, a single fiber bundle running repeatedly in the spoke star between the inner circumference and the outer circumference along spokes of the spoke star. The spokes may be formed as double spokes, the spokes having a loop at the rim-side outer circumference of the spoke star. The loops allow for a better load transfer to the spoke star.

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 structure of a bicycle wheel rim is disclosed. It comprises an inner rim frame and a composite rim body. The inner rim frame is provided with an inner rim part, two lateral ring parts respectively disposed on both sides of the inner rim part, two hooks respectively disposed on terminals of the two lateral ring parts, and an opening formed between the two hooks and having a supporting part. The composite rim body encapsulates the inner rim part, the two lateral rings and the two hooks.

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 rim for a bicycle wheel includes a radially outer tire engaging portion having a first tire retaining portion and a second tire retaining portion spaced apart from the first tire retaining portion. The first tire retaining portion includes a first tire retaining section having a first outer wall and a first tire retaining wall opposite and spaced apart from the first outer wall. The second tire retaining portion includes a second tire retaining section having a second outer wall and a second tire retaining wall opposite and spaced apart from the second outer wall. The radially outer tire engaging portion is made of a composite material. The first outer wall and the first tire retaining wall, and the second outer wall and the second tire retaining wall, respectively, are separated by a material having a lower density than the composite material.
