Inseam size up to 6 years

Until your child is 6 years old, it is best to take the size of the bike with a saddle size that allows him to put at least both feet flat on the ground.

Therefore, your child’s height must be equivalent to or greater than the minimum saddle height.

Inseam size after 6 years

 After 6 years, a child is more comfortable on a bicycle; you can afford that once seated on the saddle, only the tiptoes touch the ground.

 In this case, the minimum seat height can be between 5 and 10 cm above your child’s child height.

Where can I find the minimum saddle height?

It must be provided on the bike’s characteristics and the manufacturer’s. A quality mark will fill in this information because it is crucial. Don’t waste your time with this bike if it can’t be found!

Generally, the manufacturer gives the minimum and maximum saddle height and can also directly provide the recommended inseam size.
