PRODUCT DETAILS
Buying a bike for your child can be daunting, that’s why we 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 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 ZUMA line is designed to give them the best possible start in for that future…
