Have you considered a Bike Friday? You can check them out at www.bikefriday.com or call and talk to a sales rep - they are very helpful. They have both custom and stock bikes, and they can be set up for very short people, very tall people, and all of us in between. I own both an Air Glide and a Pocket Rocket - and although you need to get over the looks of the little wheels, they ride just like big wheel bikes.

You can see photos of me and my bikes in action in my cycling journals.
