I've just had two knee replacements and now have 12 years of lard to get rid of. I've started walking around the block and even gotten on to an old bike my wife gave me before my knees started to slow me down. On Saturday I had to relearn how to ride - it's a lie when they say you never forget :D Anyway I managed to get around the block, then twice, then three times. Then yesterday I rode from home nearly all the way to work and back. This arvo I'm going to do a near full rehearsal for tomorrow when I'll be riding to work and back home.
My point is, the road bike is very damned uncomfortable and I did have thoughts about going to a nearby town when my fitness levels have improved. I don't know if most cyclists develop a hard arse but I reckon those suspension type bikes might be the go. I don't want anything competitive but I would be interested in suggestions as to what is around and what I might upgrade to.
