Best Bike Size for 7-year-olds


Every 7-year-old kid wants a bike, but as a parent it is hard to know what bike size to purchase. I did a little bit of digging to figure out how to tell the right bike size for 7-year-olds and what kind of bike to buy, and it is all written down below. 

What is the best bike size for 7-year-olds? This question is complicated as it really depends on the size of your actual kid and their inseam rather than their age, but generally for a 7-year-old a bike with 20inch wheels will be the best fit. 

There are a lot of bikes out there and, to be honest, even as an adult I have a hard time figuring out what size of bike I need or what the best kind of bike is best for me. It isn’t even clear when you are shopping for your kids, so I tried to make it a bit easier by providing some extra information. 

How to Tell What Size Bike to Buy for Your 7-Year-Old Kid

It can be a little confusing trying to find bikes that work and a bike that fits a 7-year-old kid. You don’t want them to be uncomfortable, so the best way to decide what size bike to get is to measure their inseam and base it off of that. 

If you don’t know how to find your child’s inseam all you have to do is take a pair of jeans that fits them well and measure the entire length of the seam that is on the inside of the pant from the area that the pant legs come together to the end of the pants. This will give you the inseam for your kid. 

There are some great charts out there that are very helpful in identifying what size of bike to buy for your 7-year-old-kid. One of the best ones comes from the International Bicycle Fund:

This page has some really great information about bikes if you want to read more. 

If you are having a bit of trouble trying to find a bike matched on inseam there are some charts that work with the child’s height instead of inseam, and while they aren’t quite as exact they still are very useful. 

One of the best sights to find a height based graph would be Halfords. If you want to know more about their sight or this upcoming graph you can click here.

This is a great chart and is very popular with people. Our 7-year-olds deserve great bikes that are the right size so that they can ride around and not get hurt.
