GT – Grunge 20


Even our kids’ bikes are built right from the ground up – perfectly proportioned lightweight alloy frame, easy-riding low-slung design, and handling that makes every ride a breeze. Durable 1pc cranks, all-terrain tires, 2pc bars and even a numberplate.

  • 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.
