Kids grow at different rates, so it’s important to find a bike that fits their current height. Kids’ bikes are scaled-down versions of adult bikes, and they’re usually measured by wheel size. As a rule, it’s best to get your child to sit on a potential new bike and to check that they can touch the ground with both feet.

There are a number of factors that determine which bike will be perfect for your child, but one thing you can't ignore is how tall they are. You'll need to measure your child's height and compare it with the height of each bike on this chart, which we've divided into categories based on wheel size.
