GT Legit Fit Features

  • 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.
