Choosing the right sized bike is essential to provide an optimum fit for the rider. Our recommended ages provide a guide, but the physical size of your child will determine which bike you should choose.
Measure Their Inseam
The inside leg measurement is the most accurate way to guarantee you choose the correct size bike for your child:
1) Stand your child against the wall in the shoes they'll wear to ride with their feet slightly apart and flat on the floor
2) Place a book between their legs
3) Slide the book up the wall until it is makes contact with their crotch
4) Making sure the book is parallel to the floor, mark the wall at this point
5) Measure from that marked point on the wall to the floor
Once you have this measurement, you can then select which bike is most suitable for your child.
