  • The GT Mach One Pro 24 BMX Bike was designed and built as an affordable way of getting more riders into the sport without costing an arm and a leg.

    A 6061 alloy frame paired with hi-ten steel forks and bars give this mini machine all the strength and rigidity it'll need to get those younger riders learning and progressing at a consistent pace.

    The Mach One Pro 24 BMX Bike is fitted with plenty of race ready parts.

The first thing you will need to do is make sure you get the correct size BMX race bike, based on your height. BMX race bikes are sized from Mini (The smallest) through to Pro (adult) sizes. These sizes refer to the overall size of the frames and parts but the wheel diameter will remain the same at 20” despite the width of the tyres varying.

Take a ride through our handy guide to find out what size bike best suits you.

Note: there is some overlap between sizes as personal preference comes into the equation.
