2026 Specialized Riprock 20 Kids Mountain Bike - Gloss Pine Green

Season:2026

Brand:Specialized

Code:96526-8120

The Specialized Riprock 20 is the ultimate kids’ mountain bike for young riders ready to explore trails, parks, and neighbourhood adventures with confidence. Designed with modern MTB features and child-specific ergonomics, this lightweight hardtail gives kids the tools they need to climb hills, descend with control, and ride fearlessly on any terrain.

Built around a durable yet lightweight alloy frame, the Riprock 20 uses updated geometry to provide stability and responsive handling, with internally routed cables for a sleek, low-maintenance design. Hydraulic disc brakes deliver powerful, reliable stopping power in all conditions, while Ground Control tires provide superior grip and stability on dirt, gravel, and mixed surfaces.

Comfort and fit are top priorities in the Riprock 20. Specialized designed the bike with shorter cranks, a narrower Q-factor, a 130mm Bridge saddle, and narrow grips to improve alignment and ergonomics for smaller riders. This proportional fit reduces fatigue, increases comfort, and helps kids build confidence on every ride.

A wide-range 1x drivetrain ensures smooth, simple shifting and makes climbing easier, while the lightweight build ensures kids can handle the bike effortlessly on trails or around town.
