I'd have to say, everything is just about perfect on that bike, down to the chain. Of course, it would mean moving somewhere where I could actually use a recumbant and then mortgaging.
Invisiblehand, that bike caught my attention, too. I'd be that guy could do a custom design on a 406 or 349 bike. As it is, it looks like the wheel has to come off for a decent fold. I played with a lot of drawings before discovering an existing bike that worked, so maybe one day when we return to developing nation status and labor is cheap...
