A freestyle bicycle motocross (BMX) bike is specifically designed to carry out stunts, either in competitions or just for the fun of performing them. Its basic configuration is very similar to that of the racing BMX but stunt pegs attached to the wheel nuts, transmission on the opposite side to a racing BMX, and a gyro headset are all features designed to assist in performing tricks and jumps.
Opposite transmission allows "grinds" to be performed on the stunt pegs. Since this is easier to do on the drive side of the bike the transmission is positioned on this side. A gyro headset allows the handlebar and front wheel to be spun through 360 degrees without the tangling the brake cables.
Racing BMX bikes are tough, single-speed models designed for quick acceleration from the start gate of the BMX racing track. They need to cope with take-offs and landings, and the occasional crash, in short, eight-rider heats. Everything on these bikes is built for strength.
