The way you ride any bike.
I race bmx but often ride park and trails. I'd go with a Fit or Eastern
Justin Bieber's bike is a dirt bike. On the dirt bike it has a picture of him and his ex girlfriend. The dirt bike cost $10,000 which is a lot of money. The speed of this bike is 9 miles for 30 minutes.
no but you can get a dirt bike or a cruiser bike or a speed bike but i havnt seen a bmx bike yet.
if you want a bike for trails and dirt go for an eastern trail digger or a fit bike
freestyle, dirt, street
bmxing is when you ride a bmx bike and do stunts :)
Street, dirt, vert, anything
Depends what size you are im 5 feet 10 and i ride a 20 inch bmx bike
A true race bike is probably lighter, and may have another brake set up than a "normal" BMX. also you might have different parts that make the bike itself heavier, like if you are comparing a street or dirt bike to a race bike the back rim on the street/dirt bike the axle is going to 14mm instead of 3/8 axle, but other than that theres really nothing but gearing
No, you just need to be able to ride a bike
Depends a bit on what kinds of racing you are thinking of. In MTB, there are cross-country (XC) and downhill racing, which doesn't really compare well to anything that BMX offers. XC events in particular is a lot longer than BMX races. But you can ride "dirt" with MTBs too, whic is fairly similar to BMX "dirt".
