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…

Good value and sticks well
Style: 8.7 sqft（8 pcs）, Material Type: Aluminum 197 mil, Style: 8.7 sqft（8 pcs）, Material Type: Aluminum 197 mil
For $14 for 8.7 square feet, this was more than enough to cover the important parts of the trunk of my 944. You DON'T need a roller to apply this, just strong hands and a well prepped surface. I vacuumed, lightly washed, then used 90% alcohol to clean the surface before applying. I could have used more and covered every inch, but there is diminishing returns in doing so (especially on a budget, or with a lower wattage sound system in my opinion). If this stuck as well as it did for me in a 45° garage, then it should stick just fine for you too. I will say, it is a little cheap feeling, but for the price I can't complain. There is an audible difference when knocking on the panels this material is applied to. I'm not a professional though, and if you're an audiophile, there are better options (but prepare to empty your wallet). Not sure I would do an entire vehicle with this material, but it is a great supplement.

Easy to work with
Style: 8.7 sqft（8 pcs）, Material Type: Aluminum 197 mil
Excellent product. Strong adhesive and foam cover with silver aluminum barrier. Easy to handle and install. Cuts with razor type cutter without problems. Has inch measurements on paper side to help with fitting. Good value for cost.

Good value for my application
Style: 37.1 sqft（34 pcs）, Material Type: Aluminum 197 mil
I wanted this product for heat and sound installation. Worked well for my application of insulating Jeep floorboards. Easy to work with. Good adhesion. I may have went for a little thicker material. But it's better than only carpet. That's what Jeeps have so it worked great for me. Good value for the money, I like the size of the squares since I needed to do a lot of trimming anyway.

Good value
Style: 16.3 sqft（15 pcs）, Material Type: Aluminum 197 mil
Works well in installation but recommend an aluminum foil tape to go over all seams. Seems to work well as a heat insulator. Not sure about durability UNTILL we get some years under our belts.

Absolutely zero difference. Anyways, I have both doors full of the stuff. I'd pass if I were you.
Style: 8.7 sqft（8 pcs）, Material Type: Aluminum 197 mil
Not what I was thinking. I've used insulation like this that was composed of heavy material, this one is not. This product must be for boats or airplanes where weight is a primary consideration and noise is not a problem. This is too light to have an effect on vibration or road noise. Absolutely zero difference. Anyways, I have both front doors full of the stuff and I'd pass if I were you.
