New Birdy. Love my Birdy, would like to check out the new version.
Bike Friday. Specifically a Rohloff like Fietsbob's, with disk brakes and room for 2" tires, please.
Ti Swift. Yum.
Moulton. APB for the 20" tires, or New Series. Not picky.
Dahon Mu Rohloff.
Pacific Reach.
Brompton. To see what the fuss is all about a lord it over all other folding bike brand owners.
Of course these are all money-no-object dream bikes. Maybe not a basic Birdy, Reach, or BF, which would be solid mid-range bikes. On the more affordable end:
Downtube Mini 8sp
Dahon Speed/Mu Uno, Curve D3, or heck even a cheap Boardwalk for fun.
Used Raleigh R20, with an eye toward upgrading.
