  • The Cobalt line combines proven geometry and dialled components giving you the best start out of the gate during the first days racing. The Cobalt Expert steps up to a 19.5" top tube, a longer 50mm reach cobalt stem, a slim radio pivotal seat and wider 1 3/8” Arisun XLR8 tyres. All Cobalt bikes feature fully sealed front hubs and integrated headsets, making them simply unstoppale when comparing price to spec.

RACE BIKE SIZING

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.

Imperial (feet & inches)

Metric (cm)
