Buying a bike for your child can be daunting—that's why we developed the Zuma range to make it easier. Based on the concept of a kid-sized MTB bike, the Zuma bikes are incredibly lightweight. They feature a carefully researched geometry and are 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 and weekend rides with the parents.
These carefully spec'd bikes feature a super lightweight alloy frame and fork with double-wall rims and children's-specific aftermarket components from Promax, KMC, FSA, Vee Rubber, and Satori, making them suit the rider's size perfectly while keeping the look, feel, and ride of a high-end, full adult size MTB. Children are the future, and the Zuma line is designed to give them the best possible start for that future.
