An 18-inch BMX is worth considering for younger riders who find a 20-inch BMX too large. Smaller wheels and a more compact frame can make the bike easier for a smaller rider to handle when learning basic tricks and manoeuvres. Weight and handling also depend on the model’s geometry and components.
If your child is just getting into BMX, choosing a bike that fits can help them feel more comfortable and in control.
Whether you’re learning your first tricks or improving the skills you already have, our 18-inch BMX range gives younger riders a choice of bikes for getting more out of their riding.
Before you order, read our Important Information Before Buying and Riding a BMX Bike for guidance on assembly, the initial service, maintenance and riding safety.

An 18-inch BMX has smaller wheels and usually a more compact frame, which can make it easier for a smaller rider to handle. A 20-inch BMX is the standard size for older and taller riders, although frame lengths vary. Compare the fit and weight of the actual models you’re considering.
Yes. An 18-inch freestyle BMX is a proper trick bike, with a smaller size for younger riders. You can use it to learn bunny hops, manuals and your first skatepark tricks, as well as ride a pump track, within the model’s intended use.
A properly fitted helmet is essential riding equipment. Knee and elbow pads are also worth considering when learning tricks, especially when starting out.
Freestyle BMX bikes use one gear to keep the drivetrain simple and robust. There’s no derailleur to catch on obstacles or get damaged during tricks, jumps or falls.
