Kids Bike Sizing


Guide To Kids Bike Sizes

Need help finding the best bike size for your child? Follow our size chart and tips to help you determine the best size bicycle

We know, it feels like your little one was just learning to crawl yesterday. But, in terms of milestones, you’re at a big one! Maybe your child is ready for their first bike or maybe they’re growing and ready to size up their ride. Either way, we are here to help.

We recommend taking some measurements to find the best fit. You will want to measure your rider’s height and inseam length to choose the most appropriate bike wheel size (ranging from 12-26 inches).

Check out our handy size chart to determine the right size for your child.

Height Range 28” - 38” 36” - 40” 38” - 48” 42” - 52” 48” - 60” 56” - 66” 60”+
Age Group 1 - 4 3 - 4 3 - 7 5 - 9 7 - 13 10 - 15 Adult
Wheel Size 12” 14” 16” 18” 20” 24” 26”

Q: What are the sizes based on?

A: Kids' bike sizes are best determined by wheel size. This directly correlates to the frame size: as the diameter of the wheel increases, so does the frame size of the bicycle.

Q: Do bike sizes correlate to kids’ ages?

A: Yes and no. You can often estimate what size bike your child will need based on their age, but the best way is going by their height. Kids’ heights can vary quite a bit, what with the growth spurts and all, so using their height instead of age will provide a much more accurate way to determine the appropriate bike size. And of course, you should have your child test ride the bike before purchase when possible.

Now you’re ready to shop for your new ride (and maybe shed some happy tears as you watch yor child ride off into the sunset). Just don’t forget a helmet!
