Introducing the "Specialized Riprock 20" Kids Mountain Bike - where fearless FUN meets expert design! Unleash your child's imagination and conquer the trails with a bike built for ultimate excitement. The Specialized Riprock is more than just a bike; it's a gateway to a world without limits. 

Fearless riding starts with a bike that can handle it all. That's why Specialized crafted the Riprock with cutting-edge features like modern geometry, Ground Control tires for unrivaled traction, hydraulic disc brakes for precision stopping power, and cleverly hidden internally routed cables for a sleek look and smooth performance. But they didn't stop there – added a wider-range drivetrain, ensuring that every climb becomes a triumph and every downhill a thrilling adventure.

Comfort is key to confident riding, and they cracked the code with Riprock. Specialized revolutionized everything from how your young rider grips the handlebars to how they sit on the saddle. Thanks to meticulous data-driven design, this bike is perfectly proportioned for kids, ensuring a comfortable fit that boosts confidence. Because when comfort and confidence team up, there's no trail too daunting, no challenge too big.

Let your child experience the joy of riding without fear. The Riprock 20 is not just a mountain bike; it's a ticket to boundless exploration, limitless imagination, and the purest form of exhilaration. Get ready to watch your young rider climb higher, zoom downhills with glee, and fearlessly take on any trail that comes their way. It's not just a bike – it's a journey of fearless FUN!

A 130mm Bridge saddle, as well as a narrower Q factor and shorter cranks, offer improved alignment between the hip, knee, and ankle to decrease the risk of injury and increase pedal power. Narrow grips and updated frame geometry offer improved bike handling, inspiring riders to ride more.
  • A lightweight package, complete with an updated frame and wide-range drivetrain, creates the perfect bike to allow riders to easily tackle climbs.
  • Trail riding starts here. Inspired by Specialized’s heritage in making mountain bikes, the Riprock offers modern MTB features such as a slack head tube angle, internally routed cables, hydraulic disc brakes, and Ground Control tires.
