Take your young Rider beyond the beginning stages of their mountain biking journey with the new 20” woom OFF 4! Stable, responsive, and equipped with high-performance components and tubeless-compatible rims and tires, it provides best-in-class value in its category.

The woom OFF 4 is happiest venturing down a gravel path, up a dirt mountain road, or on the MTB trail but will hold its own on any urban playground or paved path. Off-road capable, kid-tested and ergonomically designed for growing bodies!

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.
  • 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

Heavy chewer approved.
Style: Ball, Size: Medium (Pack of 1)
My pomsky will destroy a toy in minutes. Ropes, and the "indestructible" nylon type stuffs are no match for my furry shark. This ball has stood up to him like David. He loves the crunch and it is so much more tolerable than a squeaker. These will be a staple in his toy box - Chuckit toys are really the most durable dog toys I have found in three years.

Dogs love them
Style: Ball, Size: Medium (Pack of 2)
Our dogs love these. What’s great is that you can add more plastic (like from water bottles) if the plastic starts to fall out from the center. If you have a chewer, though, these won’t last you long. Our shepherd mix loves these and then starts to pull the rubber apart the more she plays with it. Our other dogs treat it normally, though, and those ones last forever. They also get some decent height when bounced, and they make a unique whistling noise when thrown.

Our pup loves the cronch cronch!
Style: Ball, Size: Medium (Pack of 1)
I bought our 15 month old Coton several Chuck-It toys on an Amazon deal. He is incredibly playful, mischievous, and ball/toy obsessed, especially for anything that makes noise. He can also be very destructive so I love how durable most of their products are - they’re among our longest lasting toys and worth every penny. We have yet to take them to the dog park, but they’re a perfect size for sharing in play time. And they are keeping him busy at home - that’s a good thing. He loves investigating the crunchy-cronchy-crinkly sound which is a nice change from squeakers. It can withstand his destructive chewing well-being, gentle on his little teeth. I love that. Chuck-It is thinking outside the box with a variety of balls to keep dogs engaged! I do worry about the crinkle plastic inside because it is accessible because of the air holes and it feels a little sharp. So this will have to be an at home toy so we can monitor his play.
