Obviously it depends on how much she actually rides as compared to how much he wants her to ride. We don't even know how old she is. It's a good thing nobody told me I needed an expensive bike as a kid, otherwise I wouldn't have been satisfied with what our family could afford.
I personally have a problem with buying stuff that doesn't get used. I have a 95 Trooper that carries bikes and canoes and needs 4wd for the places I go. It's beat up has almost 150,000 miles and is doing just fine. I have a 6 year old Gary Fisher that I am only now thinking of replacing because it's worn out from the amount and type of riding I do. I don't want to teach my kids that you need the newest latest thing every year. Maybe I'm not as wrong as I thought. I've sold three Magna's in garage sales in the last two years. For riding on the paved bike trails that most kids are on, those bikes will last. Of course, if you have the money to spoil your kids rotten, who am I to stop you. My kids will be the oness with a sense of value.
I think you caught me on a bad day. I'm being a little pissy!
