I tore my ACL coaching soccer...yeah figures after playing competatively for 20 years I would have to tear it coaching.

Anyways I rehabed pre-surgery to the point where I could run on it again with little pain but it would always give out on me with any lateral movement. Had surgery, re-weave of hamstring for replacement, and was skiing 4 months later. This was 10 years ago and it is as strong as ever.

A girlfriend of mine tore hers earlier this year playing soccer, she had ridden a century the day before. Her post-surgery rehab was all about the bike. She started on an excercycle, went to trainer and then to her bike. The hardest part she had was the clipping in/out part. She was really worried about putting her leg down in an emergency situation or having to get off the bike quickly. Performance wasn't an issue it was the stability if she had to do something quickly that she was worried about.

Just be careful and get stronger and hopefully you can avoid surgery. Good Luck!
