I'm a bit like @
volvostephen. The more I ride, the better the knees. But, if I take a few days off riding... WHEW!!!
However, in @
rabsaque's case, it sounds like something is definitely wrong.
I would have to guess that @
rabsaque is slightly taller than 1.85cm. However, if the height is closer to 1.85m, that would put him between 6' and 6'1".
Perhaps some pictures and measurements of the bicycle. "size"?
If you can get around without a bike, I'd take a week off from bike commuting, and see how that impacts you.
