Details

The Stomper Ace 20” from GT is the perfect bike for kids to progress their riding skills and enjoy riding their new bigger bike.  Shimano gears to help with the hills and GT’s own V-brakes make the Stomper Ace a great choice for your child’s next bike.

  • Improved geometry - GT 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 pedalling - GT bikes with the LegitFit system have their pedal positions moved slightly forward. The result: Makes it easier to pedal.
  • Shimano Tourney 7 speed
  • GT V-brakes

GT has developed a new line of kids’ bikes that utilise its Legit Fit system and are designed specifically for those growing shredders. The Legit Fit system enables GT to build kids’ bikes that have narrower cranks, proper gearing and improved body positioning. All with the benefits of optimising pedalling, balance, and speed right from the start. Even better is that it’s a system that works for kids of all ages, no more needing to “grow into” a bike.

Customer Reviews

Customer Reviews

It's actually much better looking in the metal than the pictures online. It's got decent brakes, the grip-shift didn't cause my boy any problems, the quality feels good for the money and it has decent tyres on too.

It came with 2 left pedals though, so my boy couldn't ride it on the first day we got it, but other than that, very happy.
