I'm 5'2" and have a white Pocket Crusoe, but it is not for sale. I didn't test ride one first -- I ordered mine direct from Bike Friday, providing them with measurements from my Terry Isis (17.5" frame size = 44.5 cm). BF made the top tube a little long the first time since they couldn't believe anyone really needed a 19" TT (they didn't "get" WSD all that well in 2004). I had to send it back for a re-do, so I really have no idea what "size" it ended up as, but it fits me now.

Good luck finding one to fit you -- I've seen small ones in BF's pre-owned listings from time to time.
