A rear suspension bicycle, comprising: - a front triangle defining a pedaling axis (A p); - a rear wheel swingarm configured to allow attachment of a rear wheel; - an upper linkage member (18, 20) having a first pivotal connection (90, 92) with the front triangle and a second pivotal connection (94, 96) with the rear wheel swingarm; - a lower linkage member (22, 24) having a first pivotal connection (98, 100) with the front triangle and a second pivotal connection (102, 104) with the rear wheel swingarm; the second pivotal connection (102, 104) of the lower linkage member (22, 24) disposed at a vertical position below a line connecting the first pivotal connection (98, 100) of the lower linkage member (22, 24) and a rear wheel rotation axis (A w); and - a shock absorber operatively connected to the front triangle and the rear wheel swingarm and configured to control movement of the rear wheel swingarm relative to the front triangle; wherein: - as the shock absorber is compressed, the rear wheel rotation axis (A w) defines a travel path having an instantaneous center of curvature and, - as the shock absorber is compressed, the instantaneous center of curvature moves forward and an instant center, defined as an intersection point of a linear extension of the upper linkage member (18, 20) with a linear extension of the lower linkage member (22, 24), moves rearward, characterized in - that the second pivotal connection (102, 104) of the lower linkage member (22, 24) is disposed at a horizontal position between 35% and 65% of a horizontal distance between the first pivotal connection (98, 100) of the lower linkage member (22, 24) and the rear wheel rotation axis (A w). - a front triangle defining a pedaling axis (A p); - a rear wheel swingarm configured to allow attachment of a rear wheel; - an upper linkage member (18, 20) having a first pivotal connection (90, 92) with the front triangle and a second pivotal connection (94, 96) with the rear wheel swingarm; - a lower linkage member (22, 24) having a first pivotal connection (98, 100) with the front triangle and a second pivotal connection (102, 104) with the rear wheel swingarm; the second pivotal connection (102, 104) of the lower linkage member (22, 24) disposed at a vertical position below a line connecting the first pivotal connection (98, 100) of the lower linkage member (22, 24) and a rear wheel rotation axis (A w); and - a shock absorber operatively connected to the front triangle and the rear wheel swingarm and configured to control movement of the rear wheel swingarm relative to the front triangle; - as the shock absorber is compressed, the rear wheel rotation axis (A w) defines a travel path having an instantaneous center of curvature and, - as the shock absorber is compressed, the instantaneous center of curvature moves forward and an instant center, defined as an intersection point of a linear extension of the upper linkage member (18, 20) with a linear extension of the lower linkage member (22, 24), moves rearward, characterized in - that the second pivotal connection (102, 104) of the lower linkage member (22, 24) is disposed at a horizontal position between 35% and 65% of a horizontal distance between the first pivotal connection (98, 100) of the lower linkage member (22, 24) and the rear wheel rotation axis (A w).
