Just one note of advice, make sure she is involved 100 percent in picking out the bike. Years ago we made the mistake of buying our DS a Trek and the DD a Giant, both were pretty much the same bike other than the name. Well DD was not happy as she felt the Giant was not as "cool" as the trek, ugh. We laugh about it now but I sure learned a lesson. A good deal means zip if they won't ride the bike because of the "cool factor"
