The Vitus Nucleus Kids’ 26: The new kid on the block
Let’s face it, your kid will soon ride harder than you. With zero fear, cat-like reflexes and an incredible Gumby-ish ability to crash and feel nothing, your young shredder will inevitably surpass you — so you might as well lean into it and get them a bike that’ll meet their match.
Enter the Vitus Nucleus Kids’ 26.
Inspired directly by our award-winning line of adult alloy hardtail mountain bikes, the Nucleus Kids’ 26 brings the same trail performance and hardtail fun to the next generation.
The lightweight aluminum frame utilizes the same Vitus progressive geometry found in our adult mountain bikes. It’s a build that promotes stability, control and confidence — everything you want in a bike for a developing rider.
Smoothing the trail is a quality SR Suntour XCR air-sprung fork that’s adjustable to suit their weight and can be locked out for riding on pavement. Hydraulic disc brakes with adjustable levers can be tuned for smaller hands while still ensuring powerful stopping performance, and the 1X drivetrain is simple to use and easy to maintain.
The Nucleus Kids’ 26 delivers everything a young rider needs to experience the buzz, the thrill and the fun of riding a mountain bike. Ride with them, shred with them and enjoy these fleeting years you can keep up with them, because sooner than later you’ll be in their dust.
But all jokes aside, your child discovering bikes is a wonderful thing — let’s make sure they love their bike as much as you love yours.
