Use the inseam column first, since leg length gives a better fit than age alone. Match the child’s inseam to the range on the chart, then compare the wheel size listed for that row. If the child falls between sizes, the inseam range can help you decide which wheel size is more comfortable.
Good for
- Choose a first bike size
- Check fit before buying
