Traction, control, confidence, and fun—the Specialized Riprock 20 Coaster kid's bike is the perfect bike for your kid to start hitting the trails with. With the simple coaster brake design, safety and fun aren't mutually exclusive anymore.

While there are many notable features that make the Specialized Riprock 20 kid's bike awesome, it's the 2.3-inch tires that provide a high degree of, well, shred-ability—delivering exceptional traction, control, and confidence for riding rough, off-road sections and city streets alike. And when you combine the big tires with sturdy 20-inch wheels, an easy-to-use coaster brake that all but eliminates the threat of the dreaded endo, and a single-speed setup, you have the perfect mountain bike to get your little Ripper out on the trail.
