Introducing the Zuma range - a kid-sized MTB bike line designed to simplify the process of buying a bike for your child. With a focus on lightweight construction, carefully researched geometry, and a perfect balance between basic learning and off-road riding, these bikes are ideal for smaller riders. Whether it's a casual weekend ride with the parents or tackling rugged terrain, the Zuma line has you covered.
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 bike 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…
