OK... time to get brave and post pics. Solveg, don't back out now! You gave me this courage!
I don't have a true "before" picture. My highest weight was about 415. This pic was taken in May 2007, 395 lbs. I'm at 383 now, really started focusing in early June. Next pic will be me on my bike!

(this is before all the fit adjustments - when I first got it, I didn't have good enough balance to ride it with the seat up like it should be!)
