I'd just like to thank everyone for their suggestions. I ended up getting the 15 inch women's Trek 7100. I rode around a little bit today and have to say that I really enjoyed myself. The only negative is that I got a water bottle holder placed on, but the space between the top and bottom bar really isn't big enough to accommodate the holder (holder fits in space, but not w/ bottle in it). Besides that it's a fun ride. I haven't gone that fast on a bike since I was a little kid! Thanks again and happy riding!
