Buying a bike for your child can be daunting, that’s why we developed the Radio Bikes Zuma range to make it that much easier. Based on the concept of a kid-sized mtb bike, the Zuma bikes are incredibly lightweight, with carefully researched geometry and designed specifically around smaller riders as the perfect balance between a bike for a child to learn the basics on, and a more advanced mtb for off-road riding conditions for weekend rides with the parents.
With a full range of sizes from 14” for the first-time rider, all the way through to a 26” wheeled machine for the aspiring rookie, there is a Zuma for every rider. These carefully spec’d bikes feature a super lightweight alloy frame and fork with double wall rims and children-specific aftermarket components from Promax, KMC, FSA, Vee rubber and Satori, making them suit the rider’s size perfectly but look, feel and ride just like a high-end full adult size mtb.
Children are the future, and the Radio Bikes Zuma line is designed to give them the best possible start in for that future…
