How to find your Kids’ Bike Size
Determining the correct size for your child's bike is vital to ensure it's both safe and comfortable for sustained use. While there's no substitute for trying the bike out in person (simply pop into your nearest Decathlon store for a test ride), you only need one measurement to find the right bike size for your young one.
The key measurements to consider are your child's height and age. If you don’t have a tape measure to hand, don't worry: we have height charts displayed in every Decathlon store, allowing you to take measurements there and then. Consult our children's bike size chart below to see which wheel size is the best fit based on height.
