I recently purchased a BTO fixed gear Pocket Rocket. It has the pivoting rear dropouts like the Ticket. Very nice setup. Plus, I can simply swap the right dropout for one with a derailleur hanger if I ever want to have multiple gears. Folding & unfolding the bike with the pivoting rear dropouts is easier than with the track dropouts as is fixing a flat, etc. I'm extremely happy with the Bike Friday. I've had a couple of Dahons & I would not recommend them if you want a stiff handle post. However, the Bike Friday's post is very stiff, as is the rest of the frame.
I ordered it from Peter Berra at Bike Friday. He sized it perfectly, the fit is exactly the same as my Surly Cross-Check & Litespeed Classic. I can't speak for the Swift, but I can't imagine not being happy with a Bike Friday.
