I was looking at this strange bike with "training wheels" on it and wondering "what the..." A few minutes later a guy in a wheelchair rolls up next to it, pulls himself onto it, positions his feet on the floorboards, rolls back, points the bike downhill, starts it and takes off. Hits a switch and the struts lift up and off he goes. I talked to a guy watching and he said this guy races!, and he's fast! He has two people hold the bike up at the start (in the back of the pack) and he usually finishes 2nd or 3rd. And you thought you were a dedicated rider!
