Well, new to me, that is. Since reading Sheldon Brown's page extolling the virtues of the Raleigh Twenty and finding others, like Tarik, I have coveted one. So last night, tooling around on eBay, I found one with a $49 bid on it and an early morning ending time. I looked before leaving for work this morning and after calculating freight, put in a bid that I found comfortable. These things have been going for $200 - 300. I got to work and did a few chores, then checked my email. To my shock and excitement, I won. Now I get the fun of making it work for me.
The appeal of these bikes, I find, is the "hackability" of them. Certainly, there are lighter, more advanced folders out there now but Bike Fridays and Dahons and Airnimals don't take on so readily the personalities and whims of their owners.
