Forget all of the complicated parts on your bicycle. The gears,the chain,the frame. Sure, they seem important, but you really don’t need them. The Bicymple is as uncomplicated as a bike can get.
What you see here is a working prototype created by Josh Bechtel of Scalyfish Designs. You won’t find the usual frame here, or gears or even the sprockets and chain. This is basically not much more than two unicycles slapped together. Its steel frame is just two minimal bars that run above and between the two wheels.
By removing all of those extra parts, what remains is a simple no frills bike. A direct-drive, freewheeling hub joins the crank arm axis with the rear-wheel axis, shortening the wheelbase and minimizing the design. The front wheel has a standard disc brake mechanism on it. Simple. What do you think? Would you ride it? It doesn’t look very comfortable to me.
