I started riding 'bents in 1996, when in my early 40s. I continued riding upright frames as well, but the recumbents were just more fun, so I rode them more and more, and tended to go on longer rides. And it was fun to find that I was easily keeping up with riders 20 years younger than me (on flat and rolling terrain).

A year ago, I added a trike to my stable because they are fun, too. And I find that lots of people of all ages are intrigued by the trike, partly because it looks different and partly (I suspect) because I am obviously having fun when they see me riding it.
