Description

The Launch carries on as a reliable bike and an awesome value. Whether it is your first BMX or your second, the sealed integrated headset and sealed bottom bracket bearings will keep you riding longer with much less maintenance.

The geometry is just right, responsive but still stable, so it is suited to all types of BMX riding. Big 2.40" tyres provide loads of grip and Kink Hemlock pedals keep your feet locked on. Available in Translucent Black, Mirror Red and Earth Bronze.

Features

Sealed bearings where it counts. A sealed integrated headset and sealed mid bottom bracket keep the bike rolling longer between services.
Geometry that is responsive but stable. A 20.25" top tube, 75° head tube and 13.25" rear end make it suitable for all types of BMX riding.
2.40" tyres for grip. Wide rubber holds its line on rough concrete and takes some of the sting out of hard landings.
Mission Triumph 170mm cranks. 3-piece tubular chromoly on an 8 spline interface, so the drivetrain is not the weak link.
Three colourways to pick from. Translucent Black, Mirror Red and Earth Bronze, all with Kink Ace grips, Thrust bar ends and a Bold HRD 50mm stem.

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.

Top Tube Length - 20.25

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 height	Wheel size	Top tube
60 to 91cm	12"	12 to 12.5"
81 to 106cm	14"	14 to 14.5"
96 to 122cm	16"	16 to 16.5"
122 to 147cm	18"	18 to 18.5"
147 to 157cm	20"	19.75 to 20.25"
157 to 168cm	20"	20 to 20.5"
168 to 175cm	20"	20.25 to 20.75"
175 to 183cm	20"	20.5 to 21"
183 to 190cm and up	20"	20.75 to 21.5"
160cm and up	22"	21 to 22.25"
160cm and up	24"	21.75 to 22"
160cm and up	26"	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.
