While searching for a recumbent, I became a big fan of the Recumbent Cyclist News (RCN) .http://www.recumbentcyclistnews.com/
There 2000 Season Preview issue had an article "How to Buy a Recumbent". The article said that Bike E's were good for short-average riders. I am a short rider (27" inseam) I have never ridden a Bike E. One of the RCN recommendations for short riders was Rans bikes. http://www.rans.com/bikes.htm
I bought a Stratus. I also test rode both the Tailwind and the Wave. Both of them were very comfortable. You might look in their direction. Easy Racer also has a highly rated entry bike that has a low seat height, the EZ-1. http://www.easyracers.com/ Test riding is still the best answer, though not always possible.
Hi. I have a BikeE AT which my 4' 9" daughter tried and didn't like because she had to move the seat so far forward that it felt to her like she had a trailer behind her. In other words she was too close to the front wheel. Good Luck, Keith
