NEED HELP WITH SIZING? - TAKE THE BIKE SIZER QUIZ

LET'S FIND THE PERFECT SIZE

If you’d rather skip the bike sizer above, check the table below. Measuring your child’s inseam is the best way to find the right fit. Height and age work too, but they’re only a guide.

We’ve also put together a detailed artical with considerations and tips to help you choose the perfect bike size for your child. Check it out for more in-depth information!

Once your bike arrives, take a moment to make sure it’s a great fit for your child. If it’s not quite right, no worries — you’re covered by our 100-day easy returns

    A Guide to Inseam Measurement

    How to measure inseam video guide

    • Have your child stand against a wall with feet slightly apart (without shoes on).
    • Use a narrow book or similar and position between their legs, at the top of their legs, like a saddle.
    • Ensuring the book is level, note where the top of the book touches the wall.
    • The distance from the ground to the top of the book is the inseam measurement.
    • Once you know which size you need, check out the base 16, base 20 or base balance or contact us if you need further support.
