It was about a month or maybe five weeks before I could ride my bike again. Then it was just some easy cruises on my hybrid. You can probably pedal a trainer or spin bike pretty soon after surgery if they are set upright for you. Full recovery was probably ten weeks or so....but it is a gradual and subtle process near the end. After six weeks you should feel pretty good but you just don't want to shock or overuse the shoulder. Good luck on the surgery.
