The Academy Trooper BMX is a dialed BMX bike with some new upgrades on the 2021 model. It now comes with a sealed mid bottom bracket and sealed hubs for a high-quality ride. This bike is for somewhat smaller riders with a 19.5" top tube and 20x2.3" tyres. You still get the tough Hi-Ten steel frame, forks, and 8.5" rise bars. The 3 Piece forged crankset is paired with a 25t sprocket for a reliable ride. As with most Academy bikes, the Trooper is built to give you great value so that you can get the most out of every ride.


Made with high-tensile steel, this is the perfect frame for those looking for something strong enough to take a beating without breaking the bank.


The standard for high-end BMX bikes, 3-piece cranks are stiffer and stronger, meaning you can smash it at the skate park with confidence. 


Sealed bearings in the front and back hubs offer reliability and reduced maintenance needs.

What is this bike used for?

This bike is a perfect entry-level BMX for learning to ride in the parks and streets.

Why is this bike different?

This bike offers strength and reliability with the hi-ten steel frame and the sealed mid bottom bracket and hubs in a slightly smaller 19.5" TT frame. 

Who is this bike designed for?

The Trooper is for people just getting started with their journey into the BMX world.
