Step 1 - GATHER YOUR TOOLS
You’ll need a book, a measuring tape, and your child in their favorite pair of shoes.
Step 2 - MEASURE
Have your child stand against a wall, place the book between their legs and raise the book up until it hits their crotch. Measure from the top of the book (make sure to hold it level) to the floor.
Step 3 - FIND YOUR SIZE
Subtract 0.5 inches from the measurement and that is the inseam measurement, or what is also called the “standover frame height” for your child (we recommend subtracting 0.5 inches from their inseam because you want your child to be able to place their feet flat on the ground when standing over the bike). See the below chart for best fit.
