A quick release mechanism for bicycle parts that comprises a locking mechanism and a rod. The locking mechanism comprises a fixed locking core and a rotating housing handle. One end of said rod is attached to the fixed locking core. Said rotating housing handle has a ring-shaped base with two rings separated by an inner cavity. The inner side of said ring-shaped base has several punctures in it. Said rotating housing handle has locking pins designed to be inserted into said punctures in said inner side of said ring-shaped base of the rotating housing handle. Said locking pins are designed to be inserted into said fixed locking core. Said rotating housing handle serves both as a rotating housing of said locking mechanism and as a handle of said quick release mechanism.

An apparatus includes a first component having with a first coupling surface and a first axial aperture therethrough. The first component has an axial recess in the first coupling surface. The apparatus further includes a second component having a second coupling surface and a second axial aperture therethrough, and the second component has an axial protrusion extending from the second coupling surface. The axial recess of the first component and the axial protrusion of the second component selectively engage to radially lock the first component relative to the second component and align the first and second apertures upon engagement with each other. The first and second apertures selectively receive a bicycle wheel axle.

A bicycle wheel securing structure is basically provided with an axle member, a head member, a lever member and an adjusting member. The axle member is at least partially hollow, and includes a first end portion, a second end portion and a vehicle body engagement portion. The vehicle body engagement portion is provided to the second end portion for engaging a bicycle frame. The head member is disposed on the first end portion. The lever member is configured to turn the head member around an axis between a first position and a second position. The lever member presses the head member from the first end portion to the second end portion by being turned from the second position to the first position. The adjusting member is provided inside the axle member for adjusting an axial position of the head member.

A wheel-securing axle secures a wheel to a bicycle body. The axle has a shaft and a one-way clutch mechanism. The axle includes a shaft that has a threaded section and a rotational center axis. The one-way clutch mechanism includes a lock member for contacting the bicycle body. The one-way clutch mechanism permits relative rotation between the lock member and the shaft in a first direction about the rotational center axis and limits relative rotation between the lock member and the shaft in a second direction. The lock member limits relative rotation between the shaft and the bicycle body in the first direction when the lock member contacts the bicycle body.

A vehicle wheel axle assembly comprises an axle element with a first outer face and a second outer face and a clamping assembly including a clamping element and a gripping element. The gripping element includes an axially inwardly facing grip face and an axially outwardly facing pressure face. The clamping element includes a helical threaded portion and an axially inwardly facing clamping face. The clamping assembly includes an elastically resilient element to axially bias said grip face to be axially inward and distal from said clamp face. The pressure face is axially inboard of the clamping face. The gripping element is rotatable relative to said clamping element. The clamping element is rotationally coupled to the gripping element by a coupling means at a coupling interface.

A multi-function bicycle component which fastens to a bicycle and which is rotatable relative to the bicycle frame to multiple positions to serve as a cargo rack or luggage carrier in a first position and a bicycle stand or kickstand in a second position. The multi-function bicycle component rotates at or near the wheel axis and comprises a rotation preventing assembly which fastens the multi-function bicycle component relative to the bicycle frame in a riding position. When used in conjunction with a folding bike, the multi-function bicycle component also serves as a stand to assist during the folding process, and/or as a stand when the bicycle is in the folded position. The multi-function bicycle component may also include a bicycle fender.

An anti-misassembly and anti-rotation structure for an electric bicycle includes a hub motor, an anti-misassembly and anti-rotation component, and a rear fork component. The anti-misassembly and anti-rotation component comprises a first adapter and a second adapter. The first adapter includes a first base, a first annular portion, and a first shaft hole. The second adapter includes a second base, a second annular portion, and a second shaft hole. A first inclined surface of the first adapter is abutted against a second inclined surface of the second adapter, and the outer periphery of the first annular portion of the first adapter is abutted against the inner periphery of a stopper flange of the second adapter. In this way, the cooperation of the first and second inclined surfaces enhances installation convenience and also prevents the hub motor from driving the rear fork component to rotate.

A torque support assembly, for supporting a torque of a hollow shaft onto a frame of a bicycle, comprising a cam comprising a cam hole for receiving therein a distal end of the shaft, wherein the cam hole and the shaft are interlockingly shaped for rotationally locking the cam and shaft with respect to each other, an adapter interface comprising a first face defining a seat for the cam, and an adapter interface through hole which extends from the seat on the first face and is coaxial with the cam hole for allowing a thru-axle to extend there through. The adapter interface comprises an upstanding wall, extending outward from the first face, defining an inner support surface of the seat on which the cam is supported against rotation.
