GT have been making Kids Bikes much longer than most, so they understand a Junior Mountain Bike needs to be perfectly proportioned to ensure a fun and exciting experience to keep kids hooked. With the GT LegitFit system, frame geometry, crank and pedal position are all tailored specifically to youth statures, to improve ergonomics and for a more natural pedal stroke. The result is a bike with excellent stability, pedal efficiency, and confidence inspiring handling. The Ace 20 features a lightweight GT aluminium MTB frame and comes paired with a Hi-Ten Steel rigid front fork, a modern kids bike combo which ensures the Bike is as lightweight as possible as well as maximising pedal power, making the bike much easier to ride, as well as faster! The Shimano Tourney 1x7 speed drivetrain provides the performance and reliability needed from a proper MTB. While the twist shifter and short reach brake levers mean little hands are always in control, so they can focus on simply having fun.
