BMX= Bicycle Moto-Cross. im not sure if theze r the exact correct wordz, but anywayz. im sure uve seen the dirtbikerz that ride trackz in stadiumz on actual motorcyclez, thatz called motocross or supercross. BMX iz the same, but with actual peddal bikez that r smaller an only have one gear. sumbody correct me if im wrong.
