Kids' bikes are about fun, memories, and freedom on two wheels. Whether it's their first bike or a larger size, our guide helps you choose right. Enjoy the ride!

Kids' bike “size” is determined by the diameter of their wheels.  

Bike shops will stock bikes in sizes:

12”, 16”, 20”, 24” and 26”

While age is a good way to try to determine what size your kid’s need, their height is ultimately the best way to determine what size would work for them.

The chart below gives you a good idea of what size would work for your child, based on their height.  

While it’s good to buy them a bike that would fit them now, when your kids are between sizes, we often recommend doing the next size up.

As parents know, kids can grow so fast, so its good to anticipate that growth and buy them a bike they will grow into as opposed to out of.

Foot Position

For balance bikes, kids need their feet to touch the ground for propulsion. On training wheel or pedal bikes, the most comfortable position is with the ball of their foot flat on the pedal.

Standover Height

Ensure your child can comfortably stand over the bike with feet on the ground, leaving an inch or two between them and the top tube. This boosts confidence in stopping, mounting, and dismounting.

Mind Your Knees

Knee position and seat height are linked. Initially, kids need more knee bend for feet-on-ground comfort and confidence. As they progress, raise the seat for full leg extension and improved pedaling.

Seat Position

Ensuring the correct seat height for your child is vital. Adjust it as they progress. For balance and initial bikes, their feet should touch the ground fully. For training wheels and confident riders, only their toes should reach the ground.
