Abstract: A stability maintaining and shock absorbing bicycle front fork assembly comprises a steering spindle for pivotal mounting on a bicycle front frame. A single arm fork member having top and bottom ends is rigidly attached adjacent its top end to tope and bottom crown members rigidly attached to the steering spindle. A swing arm assembly is mounted on the single arm fork member to define a swing arm pivot axis oriented generally parallel to the displaceable axis of rotation, for pivotal movement of the swing arm assembly between a forward position, at which the swing arm assembly extends downwardly and rearwardly from the swing arm pivot axis and wherein the displaceable axis of rotation is disposed forwardly of the steering axis and rearwardly of the swing arm pivot axis, and a trailing position at which the displaceable axis of rotation is disposed closer to the steering axis than when in the forward position.

Abstract: A stability maintaining shock absorbing bicycle front fork and trailing arm assembly comprises a hub member attached to the steering spindle for pivotal movement therewith. Left and right fork members are attached adjacent their top ends to the hub member. Left and right trailing arms are pivotally mounted one on each of the left and right fork members. A bicycle wheel mounting member is disposed on each of the trailing arms so as to permit mounting of a front bicycle wheel thereon. In use, the left and right trailing arms are concurrently pivotally movable between a forward position whereat the axis of rotation of the front bicycle wheel mounted on the trailing arm assembly is disposed forwardly of the steering axis and between the steering axis and the common pivot axis, and a trailing position whereat the axis of rotation is disposed closer to the steering axis than when in the forward position and is also displaced vertically closer to the common pivot axis than when in the forward position.
