i'm with the go with platform pedals team. If someone had done that to me at the same age I just flat wouldn't have tried it! she really is a trouper and really wants to please her dad. But she'll have a lot more fun on easier trails AND platform pedals.

My sons rode a double century ages 11 and 13 with platform pedals. They did very well. had a great time. why complicate something like that? like someone else said; falling hurts!
