I know this is an old thread, but it's important for folks to know that having enlarged prostate surgery need not cause an end to your cycling. I had Green Laser Surgery, and only four weeks after my operation, I'm already taking long bike rides. You can learn more about the entire process via my blog. I documented the entire process from my initial trip by ambulance to the emergency room, to Nordic skiing 23+ miles in one day just 8 days after my surgery. I waited four weeks for my first bike ride due to great Spring snow conditions. I did not want to stop skiing!
