How do I measure my child's inseam & why is it important?
Your child's inseam determines how far off the ground their heels will be while sitting on the Guardian Bike. This measurement adds
5% more accuracy when determining the correct bike size.
Confident riders on 16 inch & 20 inch small bikes can be on their tippy toes 2.5 inches, while less confident riders should be on their tippy toes max 0.50 - 1.50 inches.
Confident riders on 20 inch large & 24 inch bikes can be on their tippy toes 3 inches, while less confident riders should be on their tippy toes max 1-2 inches.
Formula to calculate how far your child will be on their tippy toes:
(min seat height) - (inseam)
To Measure Inseam:
1. Have your child stand tall, with their feet shoulder width apart (shoes on)
2. Place a book up between your child's legs as high as it can go (we want to measure to the point where they will be sitting on the seat; this is different than measuring pant inseam)
3. Measure from the ground to the top of the book to get their inseam measurement.
16 inch =18.5 - 23.5 in
20 inch (small) = 20.8 - 26.8 in
20 inch (large) = 22.5 - 28.5 in
