BMX

Choosing a BMX bike

BMX bikes are built simple and strong: one gear, a stiff steel or alloy frame, 20-inch wheels and tough parts that cope with jumps, rails and hard landings. The right one depends on where you ride and how tall you are.

Street, park or pump track?

• Park and street: freestyle BMX with pegs or peg-ready axles, a rear brake and grippy tyres for concrete.
• Pump track and dirt: lighter builds with knobblier tyres for loose surfaces and rollers.
• Racing: lightweight race frames and gearing built for speed out of the gate.

Getting the size right

Top tube length is the key measurement on a BMX. Most adults ride a 20.5 to 21 inch top tube, while smaller and younger riders suit 18 to 20 inches. Bar height and crank length matter too, and the easiest way to get it right is to stand over a few bikes in store.
