A trailing link, multi-link suspension assembly for a cycle having improved stability includes a steering fork having a steering axis, a first arm, and a second arm. A shock absorber has an inline configuration, a gas spring, a first shock mount, and a second shock mount. A spring unit has a gas spring comprising a spring body, a first spring mount and a second spring mount A mechanical trail distance increases as the suspension assembly compresses relative to a fully extended state.

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 trailing link, multi-link suspension assembly for a cycle having improved stability includes a first arm having a first arm fixed pivot and a first arm shock pivot. A shock link has a shock link fixed pivot and a shock link floating pivot. A shock absorber has an inline configuration, a coil spring, a first shock mount and a second shock mount. A wheel carrier has a wheel carrier first pivot and a wheel carrier second pivot spaced apart from one another, and a wheel mount that is adapted to be connected to a wheel. A control link has a control link floating pivot and a control link fixed pivot, the control link floating pivot being pivotably connected to the wheel carrier second pivot, and the control link fixed pivot being pivotably connected to the first arm control pivot. A mechanical trail distance increases as the suspension assembly compresses relative to a fully extended state.

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.
