GT Stomper Ace 2022 Kids MTB 20" - White/Deep Teal/Moss Green

Regular price £350.00
Tax included.


Small wheels don’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 microSHIFT 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.
