Description

Close you eyes mum, these kids are ready to send it off the gate and the first jump and the Position One Junior is built to handle the rough and tumble of the Sprocket classes with an all aluminium frame and 100% CrMo forks ready for action. It's also nice and light, 7.7kg!

Other key components have been spec'd to increase durability and decrease maintenance. The alloy rims are double-walled which brings increased strength and the front and rear hubs are sealed to repel the dust from the track. 130mm Alloy three-piece cranks and smaller platform pedals all contribute to a package that has all the thoughtful touches of a bike suited for your youngest, and when they've outgrown it, because of the quality of construction, it'll be perfect for your next kid in line for the gate.

Features
  • Built for the Sprocket classes. An all aluminium frame with 100% CrMo forks handles the rough and tumble of gate starts and first jumps.
  • 7.7 kg without pedals. Light enough for a junior racer to handle on the gate and in the air, without giving up frame strength.
  • Sealed hubs front and rear. Double contact seal bearings repel the dust off the track, so there is less maintenance between race nights.
  • Double wall alloy rims. The second wall adds strength through landings, laced 24H on 14 gauge spokes with Arisun XLR8 20x1-1/8" tyres.
  • Three-piece 155mm alloy cranks. Geared 40x16 through a KMC Z33 chain, with platform pedals and 130mm grips scaled to a growing rider.

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.

BMX race bike sizing

Race frames are sized by class, and the class you ride is set by rider height rather than age.

Mini (20" wheels)110 to 140cm17 to 18"

Pro XXXL175cm and up22"
Pro XXXXL180cm and up22.5"
Cruiser (24" wheels)175cm and up21.5" and up

Heights overlap between classes on purpose. Where you land in two, a growing rider is usually better on the larger, and a rider who wants the bike to turn faster on the smaller. Some brands label the Pro size Pro L, with the same fit.

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.

  • Between two sizes and still growing? Take the larger size.
  • Racing gates and wanting the bike to turn faster? Take the smaller size.
  • Top tube is the number that actually changes the fit, so compare it against the bike they ride now.

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