Kids' Bike Sizing Guide

Choosing the right bike size helps your child ride safely and comfortably. As every child grows at a different pace, we recommend using both height and age as a guide, then checking that your child can sit on the bike and touch the ground with both feet.

Kids' bikes are usually measured by wheel size rather than frame size. Use the chart below to find the most suitable option for your little rider.

What Size Kids' Bike Do I Need?

This guide matches rider height, inside leg measurement, age range and suggested wheel size. For the best fit, measure your child’s height accurately and, where possible, test the bike before purchase.
