I think Knotted brings up some valid points. I also think that it is your body, your life, and if you want to kill yourself bike riding, that is your prerogative HOWEVER I do think you can ride safely and NOT kill yourself in the process. Ride dedicated bike paths, or in groups that help to keep you a little reined in from being over zealous. Ride in parks. Or do you need more of a thrill/challenge?

And please let your body heal. It would be so awful if your not allowing it the proper time to heal created a more serious problem that prevented you from ever riding again..........
