I'm sorry you got injured. I had a mountain bike about 20 yrs ago and went over the handle bars on a trail. I didn't break anything but I had difficultly breathing for a few weeks.

Funny thing is I'm seriously looking for a new bicycle. They have a new to me category a cross between a mountain bike and a street bike. I forget what they call them but $500-$600 gets you a nice one.

Do what the doctor tells you and heal up correctly and completely there really is no short cuts. Mike
