My 8-year old daughter wants a bmx bike for xmas, and I think she needs something better than some Walmart junk. She's been rollerblading since she was three, she skateboards and longboards, and she's an all-around maniac. Any good bikes/brands that would be good for her to grow with? Thanks.

Forgot to mention that she's about 53" tall.

The Boss (wife) said that the max price is $300.
