Description
Freedom is the absence of fear. And fearlessly riding requires a bike that can handle your kid’s imagination. It’s why Specialized designed the Specialized Riprock 20 8 Speed Kid's Mountain Bike to be a mountain bike inclusive of all the features needed for superior ripping—like modern geometry, Ground Control tires, hydraulic disc brakes, and internally routed cables. Finally, we threw in a wider-range drivetrain, making Riprock the perfect bike to inspire young riders to climb higher and tackle the downhills freely.
Kids can’t confidently ride if they’re not riding comfortably. With Riprock, fit comes first. We used data to reimagine everything from how they grip to how they sit to create a bike specifically and proportionally for kids. We did all this because comfort creates confidence. And more confidence always leads to more fearless riding.
-
Kids’-specific updates and features inspire confidence. A 130mm Bridge saddle, a narrower Q factor, and shorter cranks offer improved alignment between the hip, knee, and ankle to decrease the risk of injury and make your little one more comfy. Narrow grips and updated frame geometry offer improved handling, inspiring riders to ride more.
-
A lightweight package with an updated frame and wide-range drivetrain creates the perfect bike to tackle climbs easily.
-
Trail riding starts here. Inspired by Specialized’s heritage in mountain bike design, the Riprock offers modern MTB features such as a slack head tube angle, internally routed cables, hydraulic disc brakes, and Ground Control tires.
