A rear suspension (10) for mountain bikes comprises a rigid link (46) pivotally mounted at opposed ends thereof to a lower rear portion of a main bicycle frame (14) and at a lower front portion of a bicycle swingarm (16). The rigid link (46) allows for relative displacements between the main bicycle frame (14) and the bicycle swingarm (16) along two degrees of freedom and, more particularly, for displacements in an area defined by the position of the two pivots (P1, P2) with respect to a rear wheel axle (WA), by the spacing between the two pivots (P1, P2) and also by the possible deformation of a spring (48) provided between the main frame (14) and the swingarm (16). A leaf spring (48) may be used within a shock absorber system which also includes a damper in order to limit relative displacements between the main frame (14) and the swingarm (16) upon impact of the rear wheel with an obstacle.
