Never saw either parent ride a bike until after my Dad retired - just wasn't done. But when he retired he got a basic bike and rode around town - probably 5 miles or so at a time - and really enjoyed it. He continued into his 70s but became a bit concerned with his ability to manage traffic and ended up buying a stationary bike the he used til his death. I wish I'd ridden with him but at that time I was living in a different city and raising a family so just never got around to it.

My sons and I plan a bike ride around Shikoku - maybe as soon as next spring so I'll be remembering my Dad while we're riding.
