Here's a collection of old bike films that demonstrates that the standard seen-one-seen-them-all diamond frame bike didn't always rule the road. Although I wouldn't want to necessarily see all of these strange vehicles out there in traffic. That guy with the giant wheels strapped to his feet should stay off of the bike paths for sure. You've got to love the crazy tandem, trailer race with the trailer rider leaping out at the checkpoint and then having to chase the bike and hop back in.
I'm regularly stopped and queried about my bike; usually did I build it or how much did it cost? Often people are surprised to learn how long recumbents have been around. Well, as you can see, it's not such a new-fangled invention after all.
