A bicycle comprises a frame (10), a rear wheel (14) and a rear suspension, which comprises a swing arm (17) carrying the wheel and two pivot links (18, 19) spaced from one another in the fore and aft direction of the bicycle and coupling the arm to the frame to form, together with the frame, a four-bar linkage movable between a first end setting in an unloaded state of the suspension and a second end setting in a loaded state of the suspension. The links (18, 19) are each pivotably connected with the frame outwardly of the wheel circumference and are arranged so that on movement of the linkage from the first to the second end setting an instantaneous pivot centre (21) defined by the intersection of two axes (22, 23) each containing the pivot points of a respective one of the links (18, 19) moves downwardly and rearwardly with respect to the fore and aft direction.
