RADIO 16" Zuma Bike

Buying a bike for your child can be daunting, that’s why Radio developed the Zuma range to make it that much easier. Based around 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 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 Zuma line is designed to give them the best possible start in that future…
