Can she visit a bike shop with you, so you both could go out on a test ride? then she'll get some ideas about what feels good. Until you know what a bike that fits you feels like, you might make the mistake and buy and ill fitting one, which you won't ride. I did that- I went through buying two bikes at walmart, and never got into riding them at all. I just thought cycling wasn't for me. Now, I realize that neither one fit me. When I ordered my folding bike, I got lucky and it just feels good, and I want to ride it. When I went to get a hybrid, I rode a lot of them and found out what felt good- it had to feel as good or better than my folding bike. When she finds one that fits well, she'll be more likely to want to ride it- I don't want to quit when I ride my trek hybrid, I could just go on forever.
