Description

Buying a bike for your child can be daunting, so Radio built the Zuma range around the idea of a kid sized MTB. The geometry is researched for smaller riders, sitting between a bike a child can learn the basics on and a more capable MTB for off road weekend rides with the parents.

The range runs from 14" for a first time rider up to 26" for the aspiring rookie. This 20" model uses a 6061-T6 alloy frame and rigid alloy fork with Promax mechanical disc brakes, and takes children specific parts from Promax, KMC, FSA, Vee Rubber and Satori.

Features
  • A kid sized MTB, not a shrunken one. Radio researched the geometry around smaller riders, so the Zuma 20 fits a child properly rather than being a scaled down adult bike.
  • Light 6061-T6 alloy frame. Alloy keeps the weight down, so a small rider can pick the bike up, push it along and get it moving without a struggle.
  • Rigid alloy fork. The straight Zuma 20 fork is 6061-T6 alloy as well, keeping the front end light and simple with nothing to service.
  • Disc brakes front and rear. Promax DSK-310 mechanical discs with alloy BL-367 levers stop the same whether the track is dry, wet or dusty.
  • Cockpit scaled to smaller hands. 110mm flangeless grips, a 1" rise 31.8mm alloy bar and a 45mm reach frontload stem put the controls within easy reach.

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.
