GT Stomper Ace 20 inch Kids Bike Deep Teal
Small wheels don’t mean small fun: this is GT’s premium off-road, all-terrain, all-action first mountain bike. Lightweight aluminum 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.
