The bike info says it has a "race designed frame". Is that a big deal or should I get a different bike? Will it make that much of a difference than a different bike? I really like this bike!!
No, you can not use it doing tricks. It has a short wheelbase which makes it unstable, but it depends on what tricks you have in mind,generally you can't.
I wouldn't, it's a race bike designed for racing, not freestyle. They are 2 different things and the design differences are subtle but definite. Race BMXs simply aren't designed for the abuse/hard life of a freestyle BMX.
