that's a pretty damn small frame. if you are much over five feet tall, you will probably want to look for something a bit larger. i find that people new to cycling often get set ups that don't fit them very well. at best the ride can be inefficient. at worst, however, a poor fitting setup can cause pain and discomfort that turns off the rider (who doesn't realize that the problem is caused by fit) from cycling in general.
just throwing that out there.
