1. A shock absorption system for an electric unicycle comprising a system of three movable rigid levers pivotally connected to each other and to a shock absorber forming a flat closed kinematic chain characterised by the fact that the kinematic chain has two interconnected loops—one resembling a trapezoid and other resembling a triangle pivotally attached to a rigid frame of the unicycle at three points, wherein
the top and bottom levers remain parallel to each other in all positions of the kinematic chain and the shock absorber, as an integral part of the closed kinematic chain, is oriented predominantly vertically at a nonzero angle relative to a direction of cushioned forces.
