ABSTRACT:
A light-weight mechanical frame an accessory for harnessing together a multiple of bicycles, unicycles, tricycles or other human-powered vehicles and toys, consisting of a center-of-frame 360° horizontal pivot with four or more unequal length arms radiating horizontally outward therefromFIG. 1. At each arm, member, outer extremity extend lineally downward legs. Although the legs can descend at any angle, at their extreme lower ends are verticle axels, or pintles which are 360° pivoting connections for the cycles. Cycles thus mounted to a frame are harnessed and interconnected into symbiotic action capable of executing intricate riding patterns. Lone cycle riding becomes a team effort, all for one and one for all. The frame and cycles cannot start, turn or stop without coordinated teamwork—and leadership. The frame can be used by all ages and abilities, from extreme sporters to family outings where toddlers cycle can inter-connect with bigger siblings and parents cycles to socializing, touring and excercising seniors. The whole rig resembles a huge spider clutching cycles by the nap of their necks. Of course the unicycle frame is much shorter, requiring much less operating space and is more maneuverable.
