Fatboy Junior

Select a model:



So Junior wants to get rad just like Mom and Dad? Well, our Fatboy 24 has your kid's name all over it. It has all the same benefits as our "big kid" Fatboy, only it's built on 24-inch wheels for an ultra-low standover height and kids' size. Fat is fun for the whole family.

  • The frame features an A1 Premium Aluminium construction that provides the ideal blend of efficiency and durability, while the geometry creates a roomy top tube and short chainstays for easy climbing and confident descending.
  • Our A1 Premium Aluminium fork is lightweight and pairs up perfectly with the fat wheel system to soak up trail chatter and bumps.
  • 24x.4.0" Ground Control tyres help soak up bumps, while also providing a game-changing level of traction, control, and floatation for better handling out in the wild.
