My get around bike, an old trek 4300 is on it's last leg. I beat the crap out if this bike and it was good to me. I can't complain. Now im looking for something simple and cheap so I was looking at those rigid 29 single speed bike on bikesdirect. For the money they don't seem bad at all. Does anyone have any experience with these bikes?
