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.


  • LegitFit geometry adjustments improve ergonomics for kids. 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.
