How can one answer this question? I see many older people riding their bikes, I think that's what keeps them young. Several years ago, I saw a woman in her late 70's on a mixie or step thru bike, with a little
straw basket on the handlebars, just tooling along at about 5 miles per hour, (oh by the way she was wearing a skirt, impeccably attired and made up.) I turned to my husband and said "I want to be her when I'm her age. " I've never forgotten her. Yes, as you age you probabaly aren't going to race, or
climb big hills, but why would you give you your bike?
