There's always a thread or two on the go about "How old are you" and "What age did you start riding", but I've never seen a speculative thread on what age you think you'll STOP riding.
It's easy to give up bikes, I've done it a few times.
The first time I gave up bikes was in 1968 in England when I traded my Bonny for an Austin A35 van. You Anglo types here will know that wasn't exactly a step up.
What it DID mean was that I could get some nookie anytime, anywhere, as long as we were both 5'8" or under.
The second time I gave up bikes was when my son was born in 1976. No room for a bassinette and pram as well as the missus on the Beezer 650 Thunderbolt, so the 'Bolt departed and a Cortina arrived.
The third time will come when I just can't do it any more, which I hope is still a few years away.
How many of you think you'll still be riding 5, 10, 20, 30+ years from now?
