Abstract:
1. A rear suspension bicycle, comprising: a front triangle defining a pedaling axis; a rear wheel swingarm configured to allow attachment of a rear wheel; an upper linkage member having a first pivotal connection with the front triangle and a second pivotal connection with the rear wheel swingarm; a lower linkage member having a first pivotal connection with the front triangle and a second pivotal connection with the rear wheel swingarm; 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, a rear wheel rotation axis defines a travel path having an instantaneous center of curvature; and wherein when the shock absorber is in a fully compressed state, the center of curvature and an instant center of the bicycle are equidistant from the pedaling axis.
