I can't even ride it down the street without having to get off and stop. I never actually hurt them before and I'm only 17 so I doubt it's like, arthritis. Anyone have any advice? It sucks because I like bike riding, well I did when I was a kid and able to do it all day! GAH it's just so annoying. My boyfriend and I tried to go on a romantic bike ride and I just couldn't. =/ They also hurt really bad when kneeling and sometimes even walking a lot...
