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 specd 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 size perfectly, but look, feel and ride just like a high-end full adult size MTB.
