So I saw this guy on some discovery/tlc type show a while back. He was raving about the efficiancy of the bike. He would talk about how easy it was to pedal and how smooth it was. Then you would see him do it and he was not having an easy go at it. Then he would drop subtly the fact that you had to have those rounded bumps everywhere you rode it or it wouldn't work. Hmmm, sign me up. The next segway right here folks.
