A free wheel assembly with front clutches comprising a hub sleeve rotatable on a hub pin and a cassette rotatable on the hub pin, a first annular body rotatable on the hub pin and comprising a first crown gear, a second annular body associated with the hub sleeve and comprising a matching second crown gear facing the first crown gear. The first annular body is axially movable relative to the second annular body between a motion transmission configuration and a free wheel configuration and coupling members operate between the first annular body and the cassette. In the free wheel configuration, rotation of the cassette relative to the first annular body forces the coupling members to axially translate the first annular body towards the second annular body, and magnetic members active on the first annular body and opposing the rotation of the first annular body with respect to the hub pin.

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 wheel rim assembly includes a hub with a case and two flanges are formed on two ends of the case. Multiple spoke units are connected between the two flanges of the hub and the inner periphery of the rim. Each spoke unit includes a first connection member and the first end of an X-shaped spoke extends from the first connection member. Each first connection member includes a first recessed area and a second recessed area respectively defined in the outside and the inside thereof. The second recessed area is matched with the flange corresponding thereto. Each first connection member includes an engaging recess and a protrusion. The protrusion of one first connection member is engaged with the engaging recess of the next first connection member. Two covers are respectively connected two ends of the hub. The second end of each spoke is inserted into reception recess of the rim.

An air deflector that is at least partially disposable within a tubeless tire of a bicycle wheel includes a body. The body includes at least one wall defining an air input end and an air output end of the body. The body is attachable to a valve of the tubeless tire at the air input end, such that when air is introduced into the body via the valve, at least some of the air is deflectable by one or more walls of the at least one wall out of the body at the air output end.

An aerodynamic bicycle rim comprising: a circumferential outer portion comprising a circumferential outer surface, the circumferential outer portion adapted to seat a bicycle tire; a nose; and a set of sidewalls, each sidewall extending radially from the nose of the aerodynamic bicycle rim to a corresponding transition to the circumferential outer surface to form a rim body having a maximum rim body width that is greater than a maximum width of the bicycle tire. The aerodynamic bicycle rim is operable to seat the bicycle tire so that the aerodynamic bicycle rim and the bicycle tire form an asymmetrical cross-sectional shape.

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.

There is described a quick-release arrangement for mounting a bicycle wheel (2) to a hub of a bicycle frame (1) using a single-sided mount. The quick-release arrangement includes a number of levers (12) each movable between a closed position, in which the wheel is retained to the bicycle hub, and an open position in which the wheel is freely removable. A locking ring (21) is mounted to the bicycle wheel and is rotatable between an open position and a locked position. When the locking ring (21) is in the locked position, hooks (24) on the locking ring (21) are engageable with pins (26) mounted on the levers (12), to prevent the levers (12) from moving out of their closed positions. The locking ring (21) may be mounted to a lever cover plate (18) which is fixed to the wheel and arranged so as to partially cover the levers (12) when they are in their closed positions. The lever cover plate (18) may have a window (27) through which an indicator is visible to indicate the position of the locking ring (21).

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.

The present invention provides a single-point reinforcing structure for spoke of bicycle rim which includes a left side wall and a right side wall continuously extending along a circumferential direction of the bicycle rim. The left side wall and right side wall are formed at the left side and the right side of the bicycle rim respectively and are symmetrical to each other. A surface of the left side wall and a surface of the right side wall opposite to each other are connected through a connecting wall. The upper ends of the left side wall and the right side wall extend upward toward a direction close to a symmetry axis and are connected. The left side wall, the right side wall, and the connecting wall are surrounded to form an upper cavity of the bicycle rim. A plurality of connecting holes are arranged on the upper cavity.

The present disclosure relates to structures and associated systems for connecting a hub apparatus to a wheel. In some embodiments, the hub apparatus includes (1) a housing assembly having an outer radius; and (2) a mounting portion circumferentially provided on at least one side surface of the housing assembly. The mounting portion is formed with a plurality of coupling structures configured to couple the hub apparatus to a wheel rim. The mounting portion defines a first radius smaller than the outer radius.
