A kind of [[tandem bicycle]] composed of linking more than one [[unicycle]] together.  Unlike regular tandem bicycles, none of the riders are connected by a bike chain.

Real life examples of these include the Qu-ax Twin Unicycle and "Gavin Turk":[https://en.wikipedia.org/wiki/Gavin_Turk] & "Ben Wilson's":[https://en.wikipedia.org/wiki/Ben_Wilson_(English_artist)] "4H" Quad Unicycle.
