We’ve been making 24” dirt bikes longer than most bike companies, and the Stomper 24” packs years of knowhow in a perfectly sized junior mountain bike: lightweight GT aluminium MTB frame comes with LegitFit geometry for improved handling, while the Ace spec level means Shimano gears for durability, disc brakes for secure stopping, and GT’s classic styling that sets it apart from the rest.


  • 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.
