Description

Hot damn! We think we've outdone ourselves with this epic BSD ALVX AF+ custom build in the eye catching Coral colour way. This thing is a no expense-spared street beast built with BSD's amazing range of aftermarket parts.

Features
  • Alex Donnachie signature frame. The BSD ALVX AF+ with a 21" top tube, built around the geometry Donnachie rides himself.
  • Four Rude Tube LT XL V2 pegs. Plastic pegs fitted on both sides, so you can grind either way without adding parts before your first session.
  • Full BSD parts kit. Every part on this build comes from BSD's aftermarket range, from the Highriser headset through to the Jonesin pedals.
  • 2.4" Donnastreet tyres. Wide BSD rubber front and rear for grip and cushioning on rough street, laced to XLT rims.
  • Substance XL V2 cranks, 25T sprocket. The 170mm cranks come with the bottom bracket, and the Barrier Guard sprocket keeps ledges away from the teeth.

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"
122 to 147cm18"18 to 18.5"
147 to 157cm20"19.75 to 20.25"

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.
