i personally ride a subrosa salvador street 2010 its perfect as it is very light long and wide which is good for tricks such as barspins and grinds, hope this helps :)
I think a freestyle bmx should be made out of steel but I've heard bmx's are made out of chromoly or alluminion, i hope that's just for racing
It's smarter to get a BMX bike instead of a ps3.
You should try Winstanleys bmx, they have some cheap clearance bikes.
If they think they want to - sure.
it matters what you are going to use it for
No it's pointless unless you have a race bmx which doesn't have a front brake anyway
Well, if you ever intend to ride it on the streets, it should have brakes.
Because you think its' fun would be a good reason.
depends the age and size
Save up money for it
The main differences between a BMX 20 and a BMX 24 are the wheel sizes, with the BMX 20 having 20-inch wheels and the BMX 24 having 24-inch wheels. The BMX 20 is typically more maneuverable and better for tricks and jumps, while the BMX 24 offers more stability and speed. Your choice should depend on your riding style and preferences - if you prefer doing tricks and jumps, the BMX 20 would be more suitable, but if you prefer stability and speed, the BMX 24 would be a better option.
I race bmx but often ride park and trails. I'd go with a Fit or Eastern
