An axle assembly for a vehicle includes an axle shaft having a bolt end and a lever end. The axle assembly includes a cam assembly coupled to the lever end of the axle shaft. The cam assembly includes a cam housing, a cam follower shaft coupled to the cam housing, and the cam follower shaft is located coaxially within the axle shaft. The cam follower shaft does not extend the full length of the axle shaft. The cam shaft is coupled to the cam follower shaft, and a lever is coupled to the cam assembly. The lever is rotatable from an open position to a closed position, and an angle of maximum rotation for the lever between the open position and the closed position is less than 180 degrees.

A dropout assembly comprises a first dropout that includes a first through hole configured to receive an axle for a bicycle wheel. The dropout assembly also comprises a second dropout that includes a second through hole and a mounting surface. The second through hole is configured to receive the axle for the bicycle wheel. The dropout assembly also includes a rotational control mechanism that is configured to mount to the mounting surface of the second dropout. The rotational control mechanism includes a nut and a nut cover.

An interchangeable hub system for a bicycle having an internal component holding a wheel cassette and a hub shell having wheel (spokes, tires) built thereon. The hub system allows for the internal component with the cassette to be interchanged between hub shells allowing for cassettes to be interchanged between wheels sets without a number of specialized tools.

A hub for partially muscle-powered vehicles, including a hollow hub axle with a cylindrical inner through hole for the passage of a clamping axle, a hub shell rotatably supported relative to the hub axle by two hub bearings, a rotor rotatably supported relative to the hub axle, and a freewheel device with a hub-side freewheel component and a rotor-side freewheel component, each having axial engagement components for engagement with one another. The hub shell is rotatably supported relative to the hub axle in a rotor-side end region by a rotor-side hub bearing, and in an opposite end region of the hub shell by another hub bearing. The hub-side freewheel component is non-rotatably connected with the hub shell. The rotor-side freewheel component is non-rotatably connected with the rotor and is movable in the axial direction relative to the rotor and the hub shell between a freewheel position and an engagement position.

Skewer for tightening a cycle wheel to the cycle frame, such skewer including a first end having a threaded portion cooperable with a female thread of a first frame portion, and a second end having axial abutment mechanisms for contacting a second frame portion, as well as drive mechanisms to enable a user to alternately exert a tightening torque or a loosening torque. A torque limiting mechanism operational in the tightening direction is positioned between the drive mechanisms and the rod. The skewer further includes a braking device to increase the torque required to initiate the rotation of the drive mechanisms in the loosening direction. The braking device includes two mutually contacting friction surfaces when the axial abutment mechanisms are in contact with the second frame portion. When the torque limiting mechanism is operational, the braking device becomes non-operational because the friction surfaces are no longer in mutual contact.

A wheel hub assembly for tension spoke wheels is provided. The wheel hub assembly has a construction that automatically adjusts the position of the axle bearings along the rotational axis of the hub assembly to take-up slack between the axle bearings and the hub shell to prevent wheel wobble.

A quick-release device includes a tube having multiple holes defined through the wall in the first end thereof, and a seat is connected to the second end of the tube. A sleeve is located in the first end of the tube. Multiple stop members are located in the tube and movably engaged with the holes respectively. Each stop member has an inclined face defined in the underside thereof. A lever includes a cam portion pivotably mounted to the first end of an axle which extends through the tube. An end member is movably connected to the first end of the tube and is secured to the second end of the axle. When pivoting the lever, the end member is moved toward the seat or moved away from the seat to be the secure status or the release status.

The invention solves the issue of stiff mounting of a wheel to a bicycle frame. The essential feature of the invention is that in the seating nests of the axle are bulges and hollows with slanting surfaces. The outer contour of the axle's wall section, which is parallel to the wheel symmetry plane which goes through the slanting surface, has a non-circular shape, preferably the shape of a regular polygon or similar to a regular polygon or an irregular polygon or the shape of an irregular closed curve.

An axle assembly including: an axle sleeve having first and second end faces, an axially extending through opening, and a radially extending first engagement surface; and a control shaft extending within the opening and having a radially extending second engagement surface. The control shaft is axially displaceable relative to the axle sleeve and is axially retained to the axle sleeve by means of an overlie engagement between the first and second engagement surfaces. At least one of the first and second engagement surfaces is radially displaceable between an engaged orientation corresponding to the overlie engagement and a released orientation corresponding to a release of the overlie engagement. The overlie engagement serves to axially retain the control shaft to the axle sleeve and the released orientation serves to remove the overlie engagement and permit the control shaft to be axially withdrawn and separated from the axle sleeve in the retracting direction.

The invention relates to a bicycle including a frame with a fork, the fork having dropouts between which a wheel axle is mounted. The wheel axle includes a sensor and/or an electric component arranged to be connected to a control element. A detachable electric connection is provided between the sensor and/or electric component and the control element. The detachable electric connection is positioned between the wheel axle and the thru-axle.
