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.

  • Custom SR Suntour XCT fork features a sturdy construction and a coil spring that delivers 60mm of bump absorbing travel.
  • The 2.8-inch Big Roller tires not only ensure exceptional traction, but also offer greater ride quality, stability, and loads of fun.
  • The A1 premium aluminum frame is lightweight and built to withstand the tough use by kids, while the geometry features an ultra-low standover that makes it easy for your little ones to fit on and grow with the bike.
