zero cycle future

civilization can be counted as starting with the invention of the wheel (not fire - fire was discovered)

but most civilizations made do with four wheel devices for millennia

(sounds off stage left of animal farm):
Now, the civilized thing is to go on two wheels.

but the segay has made the unicycle almost practical

so what is the next step for the wheel world? clearly, no cycles - zero wheels - is the logical next step

roll on the nadabike, I say

of course, it will still be known as a bike, just like people still talk about records or phones in some places....
