The Best BMX Frame 2021

BMX bike

All BMX bikes start off with a frame, there are three main types; classic BMX which is a great choice if you chose to decide to preform regular tricks, a jumper BMX is the best bike for dirt/vert riding where you get serious air on ramps and finally a freestyle BMX where you can perform flatland.

The best BMX frame is the Eastern Grim Reaper as they it is offered in 2 different sizes for your preference of riding as well as being one of the lightest frames at only 4.75lbs with a great design on it.

Important considerations would be the weight of the frame, as an aluminium frame would be a lightweight option more preferable to preform tricks, although most BMX frames are made from steel which is light enough to manage and rigorous enough to take crashes onto the ground without damaging its structural integrity.

BMX Frame Buying Guide

Trying to find the perfect frame can be difficult when building a BMX bike. There are many factors that can play a huge role in deciding which is the most suitable frame such as colors/designs, weight and frame size.

BMX Frame


An important factor to consider when purchasing a new BMX frame is the weight, because having a lighter frame enables the rider to preform better and have better control over their BMX which leads to higher ‘bunny hops’ and easier manuals.

Frame Size

For street and ramp typically the most common BMX frame size is a 21” top tube, this allows riders to have room so that they can swing the BMX beneath them.

On the other hand for a flatland rider and regular BMX rider it may be more beneficial to ride a BMX with a frame size of 20” of shorter for more precise control and easier balance whilst riding.


Overall there are a number of BMX frames out there however not having the correct preferences can make your riding experience uncomfortable and difficult, furthermore its vital that you ensure the frame is the correct size for your style of riding!
