Beginner’s Guide

Getting into the exciting sport of BMX riding could be rather frustrating in the beginning stages. This is the calls they all various types are frames and wheels along with many different accessories to accommodate every style out there. Furthermore, these various styles could be quiet expense especially when custom parts are included.

Wheel Axles, these components come in two sizes, including a 10mm and a I4mm. On a stock standard BMX bicycle, the rear axle we usually consist of a 14mm and the front would be 10mm. The rear is thicker so it can handle the pressure when landing a jump. Many riders choose to upgrade the front axle as well, which gives them a much lower possibility of bending or damaging the axle during tricks.


This is one of the more complicated parts of building your own BMX. There are various styles and makes that can provide you with different advantages when riding. These include a small sprocket in front, which is made to give you quick power for when you need to get that front wheel up or accelerate fast within a short period of time just before a jump, but these smaller sprockets will not do you any good when racing as they cannot achieve much of a top speed.

This of it this way, when you have a smaller sprocket you will need to pedal faster to make the chain spin faster, which turns the back wheel, but with a bigger sprocket you can go much faster with lower pedal speed as there are more teeth on the sprocket and the diameter is much greater.

Keep in mind that a BMX doesn’t have adjustable gears like a racing bike or a mountain bike so choosing the right sprocket for you is very important. The sprocket uses bearings, which can also be customized to provide smoother and lighter pedalling. Since you have a bare frame, it might be a good idea to get the best before you close it up.


Unlike racing or mountain bike brakes you will find a BMX requires a unique system to allow all the different types of tricks. This is known as a split brake system or a Gyro, which refers to a company name.

Between the frame and the handle bars you need to fit a Gyro, which allows the handle bars to be turned round and round without twisting the cables. The system works with 2 plates with a bearing between them, which pulls the plates together when you pull on the break lever. Thus allowing you to hit the brakes at any time and still have the ability to do all the trick in the book.


Most people would say all BMX wheels are the same, but actually you can get a number of custom wheels to better suit your needs. These include a standard 20 inch wheel that is used on standard BMX bikes and bikes of younger riders, but some riders out there prefer the 24 inch wheel, which makes it easier to ride for tall riders and gives you more stability when doing tricks or riding on rough terrain. The 24 inch wheel are becoming more popular, but are still quite pricing depending on what you are after.
