I saw a guy on one out at White Rock Lake the other day. He didn't look so cool, and don't guess he was going to pass any cyclist ever- looked slow. It looked a tad boring, actually.
I love the intense look on that guy's face in the picture. Have you seen those little 3-wheelers that are basically a Big Wheel for adults? They have the video where these people are all bicycling around at 8 miles per hour acting like it's really exciting. Kind of what that photo looks like.
Yeah, here's the competition. Whee!

Here's a kickbike vid....sure doesn't look to me like they're going faster than a bicycle, though:
