Use our interactive Kids’ Sizing Guide to determine the right size for your child. Start by measuring your child’s height, then use that measurement to find the right wheel size in the table.
If your child is between sizes, it’s a good idea to buy the smaller size, as they will be able to control it better. A bike they can control will be safer to ride. Keep in mind you can fine-tune the fit by adjusting the seat height as your child gets taller.
Even though height is the best way to determine what size bike your child needs, their age can get you in the right ballpark. Check out popular age-to-size questions below.
