If they think they want to - sure.
Boys and girls !!
Yes but not at their expense
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
You should try Winstanleys bmx, they have some cheap clearance bikes.
It's smarter to get a BMX bike instead of a ps3.
it matters what you are going to use it for
A BMX bike is good for both boys and girls, as long as they want to do BMX-style riding, with jumps, tricks and that. If you don't want that, there are several bike types that are better, more comfortable, and more efficient for general riding-around type of use.
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.
depends the age and size
Save up money for it
Because you think its' fun would be a good reason.
