The Bicymple is a simple unicycle which removing the chain, a CroMo steel frame that is just two simple bars that run above and between the two wheel, which is a working prototype created by Josh Bechtel of Scalyfish Designs . "By removing the chain, the number of moving parts and overall complexity is significantly reduced. A direct-drive, freewheeling hub joins the crank arm axis with the rear-wheel axis, shortening the wheelbase and minimizing the design. "
