The newly upgraded 20" woom OFF AIR 4 will take its Rider beyond the beginning stages of their mountain biking journey. Stable, responsive, and equipped with a high-performance front suspension system, durable components, and tubeless-compatible rims and tires, it provides best-in-class value in its category. Off-road capable and kid-tested, this mountain bike was ergonomically designed for growing bodies and developing abilities. The woom OFF AIR 4 is more than capable on cross-country trails yet, uncompromising on gravel, pavement, or wherever the spirit leads your Rider.

FEATURES:

  • Ultralight frame: The premium aluminum frame is lightweight with a sporty geometry, making it safe and intuitive for your child to handle on their off-road adventures. The kink in the top tube means it's easy to dismount quickly, so your child can get off the saddle safely even in the trickiest situations.
  • Premium suspension fork: Fine-tune the air suspension fork to your rider's weight for optimal shock absorption, ensuring constant wheel contact and unwavering control, no matter how rugged the trail. You can also adjust the rebound and compression too – and activate the lockout function when riding on the road.
  • Ultimate design for young riders: With a low center of gravity, flat steering angle and long wheelbase, the sporty frame design provides a perfectly smooth and agile ride – and that means secure handling, good balance and a whole lot of fun for your child.
  • Powerful disc brakes: The powerful disc brakes are easy to modulate and reliable at all times – even when the weather is wet and the ground is muddy. Teamed with the child-specific, reach-adjustable brake levers, they allow your child to stay in full control in every situation.
  • Precise 9-speed gearing: Shifting is smooth and precise on any terrain thanks to the easy-to-operate SRAM X5 gearing. Kids can easily work the trigger shifter with their thumbs, with the reliable Exact Actuation™ gear technology ensuring speed and precision every time.
  • High-quality drivetrain: Optimum power transfer and smooth pedaling without dropping the chain? Not a problem thanks to the lightweight, child-specific cranks and the narrow-wide chainring that keeps the chain firmly in place even on the roughest of terrains. The cassette’s wide gear range keeps your child moving on flat stretches and steep climbs alike.
  • Grippy, tubeless-ready tires: The high-quality Schwalbe tires provide the perfect balance between low rolling resistance and good grip. With Tubeless Easy technology and tubeless-ready rims, it’s a straightforward transition to go tubeless and benefit from even more grip and comfort.
  • Age: 6 - 8 years

Worst product ever terrible seller
Style: 88 oz & 5 Presets
If I could give this review, zero stars, I definitely would. I am extremely unhappy with the whole experience I’ve had with the seller, which is woot. They have no experience in selling products. They attach fake serial numbers on items that they shipped to you and when you tell them, you have a problem they are of no assistance. I am extremely infuriated with the quality of this product. I spent a lump sum amount of money on this now piece of junk. Oh, and to add my house almost caught on fire because the product overheated. I do not recommend anybody buy from the seller. The functionality is terrible. I am going to spread the word to everybody about my experience.

Amazing product!
Set name: Sublimation Printer, Set name: Sublimation Printer
All I can say is "WOW". I was skeptical about changing over from my Sawgrass to another brand of sublimation printers. But now I wish I started here from the start! Not only does this machine cost a good amount less with the same paper sizes and options as my SG500 but the ink is cheaper per cartridge and 11ml larger than the standard 30ml I am use to. Set up was super easy, as well as the connection. My prints are bold, bright, and beautiful. I am amazed! I am thankful that the details in the prints show through no matter what material I am pressing on. As a business owner, I need a good, efficient printer that doesn't cost more than the product I am selling. I can't wait to continue using my machine. I have not run into any maintenance issue and can not speak on anything of that as of now. Attached photos; however, my camera did not do it justice.
