Fatboy 20 2019


So Junior wants to get rad just like Mom and Dad? Well, our Fatboy 20 has your kid’s name all over it. It has all the same benefits as our “big kid” Fatboy, only it’s built on 20-inch wheels for an ultra-low standover height and kids’ size. The family that eats trails together stays together.

  • The frame features an A1 Premium Aluminum 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 Aluminum fork is lightweight and pairs up perfectly with the fat wheel system to soak up trail chatter and bumps.
  • The SRAM X4 9-speed rear derailleur provides plenty of gears for your little ones to make it up and down almost anything, while being tough enough for abuse.
