Buying a bike for your child can be daunting, that’s why we developed the Radio Bikes Zuma range to make it that much easier. Based on 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.
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 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’s size perfectly but look, feel and ride just like a high-end full adult size mtb.
Children are the future, and the Radio Bikes Zuma line is designed to give them the best possible start in for that future…

Very good quality
They are firm enough for dogs to have them in their mouth but not to hard. They bounce nice and more then once. I will purchase again if my dogs wear theirs out

Very lightweight and not good for fetching
These balls are very lightweight. They feel like styrofoam. I try to use my Chuckit Chucker to throw them but they don't go very far and the wind will drift them in another direction as they are so light weight. Then, when my dog's saliva covers the ball, the moisture creates a suction in the launcher and the ball won't exit the chucker at all no matter how much force I put into the launch attempt. I guess they might be good for chewers, but not for throwing, if your dog likes to fetch. They would be good for throwing in the house as they won't damage anything.

Shockingly impressed
I have a heeler and he destroys everything. I thought I was going to be unimpressed at first thinking these were going to be shredded everywhere, but I have yet to see him destroy these and we have had them for over a month. I definitely recommend for high energy aggressive chewers.
