The first thing you will need to do is make sure you get the correct sized 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.
Cycle 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.
