Summer 2021

A Comprehensive Guide to Kid’s Bike Sizes 

Choosing the right bike for your child is essential for safe, comfortable and enjoyable riding. If a bike is too large or too small, it can be difficult to handle out on the trails. Check out the tips from our experts on keeping your child safe and giving you peace of mind on all your adventures this summer. 

WHAT YOU'LL NEED:

☐ Bike
☐ Measuring Tape
☐ Helmet
☐ Tools

Step 1: Measure your child’s inseam

Children’s bicycles are measured in wheel sizes varying from 12 to 24 inches. The right size for your child depends heavily on their inseam measurement. 

Step 2: Adjust your child’s seat

The bike’s saddle height should be positioned where the knees are slightly bent when the foot is at the bottom of the pedal stroke. Older children will feel most confident up on their tippy topes, while younger children will want to reach both feet on the ground. Make sure to insert the saddle seat post as far as the minimum insertion mark. If you need to insert it above that mark, your child’s bike is too small. 

Step 3: Let your child test ride the bike

Once you’ve chosen a bike in the proper size range, let your child test ride the bike to make sure it feels right to them. The reach, which is the distance from the shoulders to the handlebars should feel comfortable and your child should have a slight bend in their elbow. They should be able to turn the handlebars without overstretching or have any part of the bike hitting their body. 

Step 4: Bring a helmet!

Don’t forget a helmet, light, and bell to make sure your child is safe!
