BMX Bike Frames For Sale Australia – Race & Street

The BMX Frame is the biggest and most important part of your bike. Due to all of the geometry and sizes involved, a frame can make one bike feel completely different from another. The angle of the head tube and seat tube, top tube length, standover height, bottom bracket height, chainstay length and more are all very important details when deciding on the frame that is right for you. Some are designed for street, some for ramps, trails or flatland. Others can be ideal for riding a little bit of everything. It all comes down to the rider and their personal choice on geometry, size, color and more

Light Carbon BMX Frames

Why is it important for you bmx to be light and carbon fibre?

By layering fibres of carbon in a specific pattern, the frame can be laterally stiff and vertically compliant which is ideal for a BMX bicycle. Furthermore, carbon tends to dampen vibration better than aluminium, simply because of its material properties adding to the comfort aspect

BMX Frame common mis conceptions

There’s a big misconception that 20″ BMX bikes are just for kids or they’re too small for adults. That’s just simply not true. There are plenty sizes available for taller riders and below is the top BMX racing frames out there!

What determines the size of a BMX bike is the top tube length and the chain stay length. Of course there are other factors like the wheel size, handlebar rise, stem length and seat tube height but the chain stay and top tube are the major factors in my opinion.

As you know, over the years BMX evolved into all these sub categories like street, park, vert, flatland, trails and of course its original category, racing. And each category required frame designs with geometry made specifically them. Some required a shorter top tube and chain stay length to execute tricks more efficiently like in flatland, street and park. Others categories required a longer top tube and chain stay length for stability, high speeds, and jumps like in racing and trail riding.

Which BMX frame is right for you?

The vast majority of freestyle, park and street BMX frames are made from steel, which is light enough to perform tricks in the air but tough enough to take the punishment of crash landings on concrete.

BMX frames at the upper end of the market are built with 4130 chromoly steel, or ‘cro-mo’, a chrome-molybdenum alloy that is light and strong, with a plush feel that experienced riders appreciate. More budget frames usually feature frames and forks made from hi-tensile (‘hi-ten’) steel, which is strong enough to take the punishment of BMX riding but a little heavier than cro-mo with a harsher ride feel.

Some BMX racing frames use strong, stiff and lightweight aluminium or carbon fibre frames, where the emphasis is more on speed and less on ability to take abuse. However for non-racers, steel is the frame material of choice.

BMX Frame Geometry

Geometry is one of the most important aspects when it comes to handling a bike. Different frame geometries affect how your ride, so make sure you know what’s going on with BMX geometry! The angles at which these parts are made can have an impact not only in terms for turning and stopping ability but also where weight distribution falls off from its centerline (front or back). For example steep head tube angle positions riders over more frontwardly while slacked out tubes put them further behind due their positioning being farther back as well making more stable riding possible without having any adverse affects such like stability found from higher slope angles

BMX Frame Buys Guide

The Frame Buyers’ Guide If you aren’t sure what you want, it can be difficult to choose a new frame. This guide is quick and easy to follow.

TUBING – All aftermarket BMX frames, except for some race frames, will be made from high-quality, chromoly tubing from either Taiwan or the USA. Both countries make great frames, but the USA is slightly more expensive because of their higher labour and materials costs.

SEAT TUBE ANGLE: Usually between 69 and 71deg. A frame with a Seat Tube of 69 degrees will feel smaller than one with a toptube that is the same length. However, a frame with a Bottom Bracket on the frame that measures 69deg will feel slightly closer to its Headtube. It’s all triangular!

TOP TUBE – Measured from the Centre of the Head tube to where it meets the Seat tube. You will have more leg space if your toptube is longer. For street riders, shorter top tubes (20.75″) are more convenient as they can be thrown around the bike easily. Trail riders prefer longer toptubes (21.1″) for extra stability and room in the air.

STANDOVER HEAD – Measure from the bottom bracket to the top tube. Lower Standover frames make tricks such as tail whips more manageable, but can also feel unstable and squirrely. Higher standing frames may feel more stable. A taller standover frame may feel more stable because the front triangle is larger than a lower one.

CHAINSTAY/REAREND – Measured from the bottom bracket to the point where the rear axle will be in the Dropout. Street riders prefer shorter (12.5″+ Chainstay Lengths) to make it easier to spin. Trail riders prefer longer (13.75″+) Chain stay lengths to keep the bike stable in the air and prevent looping. The rear end length is slammed. This is where the axle goes as deep as possible into the dropout.

HEAD TUBE ANGLE – The steeper the Head tube, the higher the number. A 75.5deg Head tube speeds up the steering, making it ideal for technical riding and front wheel tricks. However, it is less responsive for riding transitions and big jumps, where a slower Head tube of 74.5deg or 74 deg would be more suitable. 75deg Head tubes can be used as a middle ground between modern frames and suitable for all-round shredding.

BB HEIGHT: Measure from the ground to the centre of Bottom Bracket. Usually between 11.8 and 11.5″ A lower BB is more stable and will give you more room to manoeuvre in manuals.
