When to start cycling after knee surgery?

I guess this would depend on the type of cycling you do, off road hilly, or on road flat, or hilly, the French Alps or Pyrenees, the fitness and recovery level of the individual, pain threshold, determination and tolerance of discomfort. Your body is going to tell you. In my case, as an enthusiast road cyclist with 60 years experience, and three cases of surgery involving knee arthoscopy behind me, the last in my late 60's, I threw the crutches away after 4 days and was back on the bike at 9 days after surgery, up here in the Perth Hills, Western Australia,with suitable gear ratiOS. As an encouragement to fellow cyclists, I am now 73 years, 5 days after hip surgery and determinined to be back on the bike in 14 days after surgery, to ride the French Alps in mid August, which I have been training for.
