Where Can You Get A Bmx Bike In Perth Where Can I Find A BMX Bike Shop In The East Bay?

Where can I find a BMX bike shop in the East Bay? - where can you get a bmx bike in perth

I live in Hayward, CA (near Oakland, CA). I can only find shops, mountain bikes, but sell the BMX freestyle bike. I know that Toys "R" Us sells something, but I'm looking for things of great quality. Thank you.
