Agree with the above responses - wheel size is not what really matters. To me it would be which bike, i.e. overall fit and feel, suits her best. Thus, some sort of test ride, even if it is a short one, would be highly recommended. One other thing to take into consideration - you basically can't give away 26" bikes these days, they are really not that popular anymore. This only matters, though, if you want to sell it some time down the road. Hope this helps, use it or don't, cheers.
