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 basis on. A more advanced MTB for off-road riding conditions for weekend rides with parents.
Children are the future and the Zuma line is designed to give them the best possible start for that future.
