I did about 7 years ago. I bought a "Linda Evangelista" excercise rider. Looked like a bike with no wheels and you kind of pushed down with your feet, pulled with your hands and did some kind of weird workout. Tragic. I played with it for about 3 minutes and hid it. If marketed properly (with wheels) could have been a great form of transport. Anyone every bought fitness equipment from Infomercials?
