What's the difference between a 20" small and a 20" large?Updated 9 days ago

The difference between the 20” Small and 20” Large comes down to the frame size. While both bikes use the same 20” wheels, the Small has a lower seat height, making it a better fit for younger or smaller riders

The rest of the frame geometry is then engineered to fit a child that size. Also note that the 20" Large is a 6-Speed, whereas the 20" Small is a single speed. Each frame is specially designed (geometry, seat height, and proportions) to best fit kids in its size range.

The best way to figure out which size is correct is to use our awesome RideSizer tool.

Child Height Range (MIn - Max)

  • 20 inch (small) = 43 - 51 in
  • 20 inch (large) = 45 - 53 in
