GT Stomper Ace 20 Tourney Kids Bike 2021

The GT Stomper Ace 20 Tourney Kids Bike has Small wheels but that dosen’t mean small fun: this is GT’s premium off-road, all-terrain, all-action first mountain bike. Lightweight aluminium frame and rigid fork built with LegitFit design and plenty of Shimano gears plus disc brakes mean this bike is super-easy to ride and handles like a dream. Remember that feeling of barrelling down the dirt track and coming home covered in mud while grinning from ear to ear? THAT!


  • Improved Geometry bikes with the LegitFit system feature geometry adjustments to improve ergonomics for youth statures. The result: Increased stability, comfort and confidence for a wider range of riders.
  • Easier Pedaling bikes with the LegitFit system have their pedal positions moved slightly forward. The result: Makes it easier to pedal.
  • Better Positioning bikes with the LegitFit system have narrower crank and pedal positions that match the width of a child’s hips. The result: A stronger, more natural pedal stroke.
