Children are generally taught to ride a bike at an early age.
The right size bicycle allows for a comfortable and safe riding position for children and teens, and stimulates maximum performance of the muscles.
Aside from being less tiring and preventing overexertion of the knees, the right size bike encourages regular bike use and cycling in general.
This size is usually based on the wheel diameter.

This sizing chart for children's bicycles is based on age and length.
Not everyone is the same length at a certain age, so it’s advisable to determine the bicycle size based on length.
The most important factor in determining the right bike size, is the inseam length.
Body Length | Inseam Length | Recommended Bike Size |
![]() |
120 - 140 cm | <52 cm | 16 inch | |
52 - 74 cm | 20 inch | ||
> 74 cm | 24 inch | ||
140 - 160 cm | < 62 cm | 20 inch | |
62 - 80 cm | 24 inch | ||
> 80 cm | 26 inch | ||
> 160 cm | < 74 cm | 24 inch | |
> 74 cm | 26 inch |
Most children that are 120 to 140 cm tall can ride a 20 inch bike, while children between 140 and 160 cm tall can ride a 24 inch bike.
A 26 inch bike is generally suitable for teenagers who are over 160 cm tall.
The right frame height is also very important: it is the first step to finding the correct riding position.
A bicycle frame that is too small or too large can lead to limited height adjustment options, which in turn may lead to an inconvenient height difference between the saddle and handlebars.
Use the inseam length to determine which frame size is right for you.
You can do this by measuring the inside of your leg, from the top of the thigh down to the floor.

Choose the frame size closest to your results.
When in doubt, it’s best to pick the smaller frame size.
