Since its introduction in the 1970s, the BMX bike has stood out as the bad-boy of the biking world. Forget lazy Sunday cruises and calm long-distance treks. BMX bikes are for intense racing, jumping and stunts!
There are some basic traits that many BMX bikes share; they have a compact frame design, 20in wheels, wide tyres and a single gear. They’re built for quick moves and are extremely solid to handle all the jumps and stunts you can come up with. Another option are ‘Cruiser’ BMX bikes which typically feature larger 24in wheels.
We’ve put together a guide to explain the different types and features of BMX bikes on the market, so you can make an informed choice.
As with any bike, it’s important to pick the right size. While BMX bikes are typically quite small, there are slightly larger frames available. The material of the frame dictates how strong it is. Aluminium frames are generally light, but they won’t withstand frequent abuse as well as a heavier Chromoly steel frame. Carbon fibre exists as an option in professional-level BMX Racing frames.
Different tyre treads are suited to pavement, parks or ramps. For dirt riding you’ll want a tyre with a light tread on it. A smoother tyre is needed for street and flatland riding. Racers will typically seek a narrower tyre with a fast-rolling centre, and side knobs to aid in corner traction.
Rear pedal brakes are standard on many kids BMX bikes but not on adult version. An adult BMX bike will feature at least a rear rim brake, with Australian-compliant bikes also supplied with a front rim brake. Make sure the cable allows the handle to spin around if you’re doing serious tricks. As BMX Racing bikes are used on a closed circuit and away from traffic, they do not feature a front brake.
When you’re landing hard on your BMX, especially in park and dirt riding, you want strong axles. Sealed bearings are more expensive but are ideal if you’ll be riding in a lot of dirt, dust or water. Axle pegs are a great addition for certain street tricks, but they are not allowed for racing and can get in the way if riding dirt.
Whether you’re interested in a cheap child’s BMX, or you’re looking for BMX bike shops to buy a professional-level bike, you’ll find it all on BikeExchange.
