Need a new challenge? You need a two-wheeler! This extension kit fits Axis 20 unicycles and adds an extra wheel.
Yes its a unicycle with two wheels! There's only one tyre in contact with the ground at any time, so its still a unicycle.
Just remove the bearing caps on your 20" unicycle and bolt on the Two Wheeler Extension. If your unicycle has main cap style bearing holders such as the Axis 20" the Freestyler 20" the Cyclone 20") this kit will fit your unicycle. The Extension Kit positions the two tyres so that they are touching and push each other round. To move forward on a two-wheeler unicycle you have to pedal backwards! Quite a challenge indeed.
A whole raft of two-wheeler tricks are possible such as idling, backwards, wheel walking, unispins, seat in front, gliding and spinning. See http://www.gilby.com/unicycling/photos/2wheeler/ for more, or watch Gilby's section on the Inner Balance DVD.
