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…

Great job by Asurion!
Asurion handled my claim quickly and efficiently. My return was picked up by UPS and an Amazon gift card for the full amount was received as promised. Very happy with the process.

Make sure you read the terms and conditions and don't let them off the hook
Asurion is counting on the fact that you don't know how to read. They made the claim process aggravating and as difficult as possible. I CAN read and had to review the terms and conditions with them on the phone and threaten to involve an attorney before they would honor the coverage. They tried to say my product was not portable, when the word "portable" is literally in the name of the product. Then they tried to say the the accidental drop was not covered, but it clearly states in the terms and conditions that an accidental drop and a cracked screen is a covered event. I buy the coverage almost every time I am offered it, but I will be rethinking that going forward and Amazon should consider finding a different company to issue the protection plans for their products because I fear this is the beginning of a lot of complaints. I have filed a claim in the past and it was very straightforward and easy, but they must have a new company managing the plans now, because it was anything but easy. If I was an older person who was not tech savy, or who just took someone's word at face value, I would be out the cost of my item and the protection plan. BUYER BEWARE
