Thanks for the many replies! I see it started a lively discussion. I'm the type who likes to scratch an itch. The problem is I have a garage of itches I've scratched before and I never end up riding them. So I need to sell off my unused bikes.

I really want to think this through before pulling the trigger on another ride. I started a different topic about the new Dahon Curl as an alternative to the Brompton. It looks intriguing. But unless I actually ride one, it's all academic. And then it's also a Dahon, which raises questions about quality.

I come from a recumbent background. My earlier reasons for recumbents were back support, as I also have lower back issues. But as my neck grew worse, I found the recumbents made it harder to turn my torso to look over my shoulders. My current full size bike is the RANS Zenetik. It is a crank forward bike with a very upright position, with the seat tube at 45 degrees, meaning the crank is forward from the seat. It's like the Electra Townie, only the geometry is more exaggerated, and much lighter too. It can NOT be ridden easily in an aero position. And I have a fairing to compensate for the wind load.
