UNLEASH YOUR YOUNG SHREDDER

The GT Stomper Ace trail bike is designed to spark a lifelong love for mountain biking in young riders. With 120mm of rear travel and capable 26-inch wheels, it delivers a fun and confidence-inspiring ride. Inspired by the spirit of GT's adult bikes, the Stomper Ace helps kids conquer new trails, shred with confidence, and push their limits with every ride.

KEY FEATURES FOR TRAIL TAMERS

The Stomper Ace delivers the latest tech and standards to help young riders easily progress. The 1x10 Microshift Advent X drivetrain simplifies shifting with a single, easy-to-use trigger.

ACCIDENT FRIENDLY
