I had op in April but not a keyhole job, 5" scar and mesh . It was about 3wks before I took the bike out and still abit of a struggle to swing the leg over . I was driving the car 2 days after op , dug and planted the veg plot even before thinking about the bike but the weather helped in that regard.
Your body will let you know when its ready, if it hurts dont push it.
