Radio BMX Bike | 2021 Zuma 24" SUS | 19.3"TT
Buying a bike for your child can be daunting, thats 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 basics on, and a more advanced mtb for off-road riding conditions for weekend rides with the parents.
