I too recommend test riding - especially for a short woman, it is essential! I have had several bikes in the past - all too big with poor geometry - once she gets on a good fit with good geometry, it will be easy for her to decide! sometimes it is worth it to take a day to visit several dealers in a bigger town! Good luck (ps I third the notion that she will enjoy a bike with at least 3 gears over a single speed - alot!) Tokie
