Riprock 20
2021 Riprock 20
Traction, control, confidence, and fun—the Riprock 20 is the perfect bike for your kid to start hitting the trails.
While there are many notable features that make the Riprock awesome, it's the 2.8-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, mechanical disc brakes, and seven-speed shifting, you have the perfect mountain bike to get your little Ripper out on the path to a lifetime of fun rides.
