Freestyle BMX is bicycle motocross stunt riding on BMX bikes. It is an extreme sport descended from BMX racing that consists of five disciplines: street, park, vert, trails, and flatland.

Flatland – flatland style BMX bikes have different frame geometry to traditional park BMX bikes because flatland riding requires precise balance on multiple parts of the bike.

By 1990, the roadster was almost dead; while annual UK bicycle sales reached an all-time record of 2.8 million, almost all of them were mountain and road/sport models.
A very popular "off road" mountain bike gearing, for the 26″ wheel size, is 39:18, approximately a 2:1 gear ratio and 56.35 gear inches, for versatile trail riding. A great "on road" gear ratio, for the 26″ wheel, is 42:17, approximately a 2.5:1 ratio and 64.2 gear inches for versatile tour riding.
