20" BMX Bikes

20in is the standard BMX wheel size, ridden by everyone from confident kids around 9 years old through to adults. It's the size you'll see in freestyle park, street and dirt jump riding, and it's the wheel size used for BMX racing too.

Freestyle or race?

Freestyle 20in bikes are built tougher for grinds, jumps and tricks, with a lower standover for throwing the bike around. If you're after a lighter, race-specific setup, see our dedicated BMX race bikes. Shop brands including GT and Mongoose, or browse the full BMX bikes range.
