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

While there are many notable features that make the Riprock 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.


  • 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.
  • Steel coaster brake is a reliable, easy to use brake perfect for safe stops and awesome skids.
  • 20x2.3" Rhythm Lite tires deliver tons of traction, comfort, stability, and fun over all types of terrain.
