RIPROCK 20 INT GLOSS UV LILAC / BLACK

Freedom is the absence of fear. And fearlessly riding requires a bike that can handle your kid’s imagination. The Specialized Riprock is a true kids’ mountain bike, built with the same trail-ready thinking as Specialized’s adult MTB range—so young riders can explore, climb, and descend with confidence.

Designed with modern trail geometry, wide Ground Control tyres, hydraulic disc brakes, and internally routed cables, the Riprock gives kids the control and stability they need to ride real trails. Add a wide-range drivetrain, and you’ve got a bike that helps them climb higher and roll downhill with confidence.

At Mackay Cycles, we love this bike for local riding—from family adventures to skills progression on trails like Finch Hatton MTB Park. This is where confident trail riding begins.
