Biky Size Quiz
Find the perfect bike for your child
How do you want to measure?
The simplest way, especially if the bike is a gift. But children of the same age vary greatly in height, so the accuracy is low.
More accurate method. We calculate the approximate inseam as 45-50% of height, which gives a more accurate recommendation.
The most accurate way to choose a bike. This length affects whether a child can comfortably reach the ground and feel confident on the bike.
How to measure inseam:
- Have your child stand with their back against a wall without shoes.
- Place a book between their legs so it presses against the crotch.
- Measure from the floor to the top edge of the book.
