Description

Big frame. Big energy. One dialled complete.

The Colony Cadet Elite is a full CrMo, pro-level BMX machine made to handle business—no matter where you ride. From park flow to deep trail lines or raw street spots, the Cadet Elite’s setup hits the sweet spot for bigger riders or those chasing that stable, confidence-boosting geometry.

At the core is the Cadet Elite frame with a long 21” top tube, roomy 13.25” slammed rear end, and a solid 8.5” standover—ideal for taller riders or those who like a bit more bike under them. It’s got that responsive 75.2° head angle for quick front end control and an 11.5” BB height to keep things feeling balanced and grounded. Full CrMo construction means it's built to take hits and keep pushing.

Up front, the bike features Guardian forks with 25mm offset and full heat treatment, matched with a Squareback CNC’d stem and 9.0” rise bars. The cockpit is clean, strong and ready to rip.

Rolling on Colony Pintour rims laced to a Wasp front hub and Wasp cassette rear, the Cadet Elite delivers the exact same hub tech found in many of Colony’s high-end custom builds. Paired with 2.35” Colony Griplock tyres and plastic hub guards, it’s ready for rough ledges, heavy landings and fast transitions.

At 11.2kg, it’s lightweight without being sketchy. Everything from the Venator cranks, to the Endeavour 25T sprocket, to the Much Room grips is dialled for reliability, comfort and control.

The Cadet Elite is a high end BMX bike setup for all types of riding. Be it hitting parks, trails or street riding this bike has you covered.

Assembly information

Your bike ships mostly assembled in the box. Finishing it takes most people 10 to 20 minutes with basic tools, and the video above walks through every step.

  • Fit the handlebars and line them up with the front wheel
  • Fit the front wheel, pedals and seat post
  • Check the brakes and tyre pressure before the first ride

Tools: Allen key set and a 15mm, 17mm or 19mm spanner for the pedals and axle nuts (bikes can vary between these three sizes). A socket is needed if installing pegs.

Rather have it done? Ask us about extra assembly before you order, or any local bike shop can finish the build for a small fee.

20 inch BMX sizing

A 20 inch bike is the standard adult BMX and suits riders from about 147cm up. At this wheel size the top tube is what changes the fit, so pick that by height.

Rider heightWheel sizeTop tube
60 to 91cm12"12 to 12.5"
81 to 106cm14"14 to 14.5"
96 to 122cm16"16 to 16.5"

160cm and up22"21 to 22.25"
160cm and up24"21.75 to 22"
160cm and up26"22 to 23"

Sizes overlap on purpose, so personal preference comes into it. If you land in two bands, riding style breaks the tie: longer for flow, trails and transitions, shorter for technical street and park.

How to measure

Stand your rider against a wall in the shoes they ride in, heels flat, and mark the top of their head. Measure from the floor to the mark.

Top tube is measured from the centre of the seat tube to the centre of the head tube, so it is not the same as the length of the tube you can see.

  • A 20 inch bike is the standard adult BMX and most riders end up there, so do not size a tall child down to a smaller wheel.
  • 22, 24 and 26 inch bikes are adult bikes with a bigger wheel, not bigger frames for taller riders.
  • Size up for stability through trails and transitions. Size down if you want the bike quick and twitchy for spins and grinds.
  • Top tube is fixed, but stem length, fork offset and bar position all shift how roomy the bike feels once you are on it.

Not sure? Send us their height and we will tell you what we would put them on.
