This 20 inch kids’ bike is ideal for school runs, park paths, and weekend adventures.

  • 20” wheels suitable for kids approx. 105–120cm tall.
  • Lightweight aluminium frame with youth-specific LegitFit geometry.
  • 6-speed Shimano drivetrain with twist shifter for simple gear changes.
  • Front and rear V-brakes for dependable braking.

GT LegitFit System – Designed for Kids

GT’s LegitFit system helps kids ride comfortably.

GT designed LegitFit bikes to match the size and needs of growing children. And not short-cut it, by making adult bikes smaller.

The LegitFit design on 20 inch bikes, helps kids ride with less effort and more control.
Better Fit. The frame shape helps kids get on and off the bike easily and sit in a natural, comfortable position.

  • Easier Pedalling. Shorter pedals and cranks make it easier for kids to pedal without straining.
  • More Control. A more upright riding position and light frame help kids stay balanced and steer confidently.
  • Kid-Sized Parts. Handlebars, seats, and brake levers are made to fit smaller hands and bodies.
  • With the LegitFit system, kids get a bike that feels right—so they can ride safely, confidently, and have more fun.
