Lol, that reminds me of a cool book called "The Fantastic Bicycles Book" by Steven Lindblom (if I remember right). It came out in 1980, and was directed towards kids building their own kool bikes, one project was a ski bike! They also proposed an ice cycle, much like the turn of the century original. It had a bolt-studded tire (or rim maybe), one cleated pedal on the sprocket side to drive with, and no crank on the other side. You'd put a skate on that foot! I don't think they actually built it at the time, was more of a what if. Still have that book somewhere! :mrgreen: ~Adam
