This is the ultimate page to build your own FMX bike!

Levi joined the Riders Lounge Podcast to detail absolutely everything that went into his latest FMX bike build which achieved something he set out to do, having parts which allowed Jayo Archer and Harry Bink to land the Triple Flip from a Moon Booter at Nitro World Games.

This bike is 85 kilograms wet! That means with fuel, oils and fluids it is almost 20kg lighter than a normal bike!
