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. A variable length shock absorber is securely mounted at its top end on the hub member. A linkage arm is pivotally mounted at its bottom end to one of the trailing arms, and is pivotally mounted at its top end to the shock absorber. Alternatively, a linkage arm may comprise a variable length shock absorber. A spring biases the shock absorber to its extended configuration the trailing arms to their respective forward positions.
