Specialized 20 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.

  • 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.
  • 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.
