Description

Nathan Williams' signature complete from Kink runs his own frame, fork, bars and seat: 100% 4130 chromoly with double butted top and down tubes, and a fork with adjustable 20mm or 25mm offset so you can set the front end to suit your riding.

The wheels and drivetrain are Cinema: Pilot sealed hubs front and rear with guards, a sealed freecoaster out back, 444 rims, 2.5" Williams tyres, a Sync half-link chain and a Beta 25T guard sprocket. Four C4 pegs are included. It weighs 12.79kg in Midnight Black.

Features
  • Nathan Williams signature build. Kink's Williams frame, fork, bars and seat, wrapped in a Cinema parts kit and set up the way Nathan rides it.
  • Adjustable 20mm or 25mm fork offset. Set the front end how you like it, then change your mind later without buying another fork.
  • Cinema Pilot sealed freecoaster with guards. Reverse rolls without the cranks turning, and hub guards front and rear so grinds do not chew up the shells.
  • Double butted chromoly frame. 100% 4130 with double butted top and down tubes: strength where it counts, less weight where it does not.
  • Fat 2.5" Cinema Williams tyres. Laced to Cinema 444 rims for grip on rough ground, with a Sync half-link chain and Beta 25T guard sprocket. 12.79kg all up.

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.
