Roel Verhagen of the Netherland’s entry was the Evolution Bike. I like the minimalist frame, curving from hub to hub with the forks a natural extension of this. A comfortable enough seat reclining at a nice angle. Front light mounted on the fender. The drive mechanism is by way of a continuously variable transmission. Clicking on the link takes you to a page with some discussion on some pros and cons of this type of drive; and see the truly fabulous discussion here. Evolutionary yes. Revolutionary, probably not.
