Creativity, skills, style, courage & lots of fun is what you need to ride a BMX bike. Quite a lot of people used to have a BMX bike back in the 80ties with cool BMX stickers on it.
Is BMX a bicycle brand? No it is not, BMX is the abbreviation for bicycle motocross.

It all started on motocross tracks where kids were riding their bikes for fun, racing and doing tricks. Nowadays there are 5 disciplines in BMX Freestyle: BMX Street, Park, Dirt, Vert & Flatland.
BMX street is one of the most common discipline. You only need your bike and the city landscape like handrails, stairs, benches etc. to pull your tricks on.
