Two points:

1. If you really want to see a ridiculous rider, go back about thirty years when I was wearing toe clips for the first time. I couldn't get my feet out at the light and toppled right over. I weighted less than 140 lb. at the time.

2. When I see a big fellow on a sofa pushing his sixth slice of pizza into his face by the glow of "Toddlers in Tiaras", I might think an uncharitable thought or two. When I see a big fellow riding on a bike, I think "wow, look at him, he's awesome, look at him making a change for the better -- that takes guts, and strength, to get up there and ride. Go, man, go!"

Myself, I just started riding again after topping out at over 230 lb., and all I can say is, I should have never stopped.
