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.

Specialized Riprock Coaster 20

A 20″ aluminum frame general youth bike with coaster brakes.

Plus tires, legit components, and great geometry make for a standard setting kid’s bike. “Hey dad, how do you spell ‘Mac-as-kill’?”, After years of helping my daughter google Barbie — Life in the Dreamhouse, Strawberry Shortcake, GoNoodle and the like, hearing those words drift from the computer desk and out the window to where I was working in the yard just warmed my heart. It’s a mountain biking father’s dream.
