How do I measure the correct bicycle size?

Are you unsure between two sizes? Always consider your child's height instead of age. After all, children grow at their own pace. A helpful tip is to measure the inseam:

  • - It is best to put your child against the wall with his or her shoes on.
  • - Measure the distance from the cross to the ground.
  • - Compare this with the frame height of the bicycle.


Note: Don't buy a bike too big for your child's growth. If a child can't reach the ground properly, they'll feel insecure and accidents are more likely to occur. At BikeFlip, you can easily switch to a larger size once your child has grown.

Helpful tips for choosing a Children's Bike:


  • Measure your child's height: Make sure to measure your child's height and use this information when consulting our size chart.

  • Avoid bikes that are 'too big': Be careful with a children's bike that is too large. A bike that is too big can be dangerous and reduce the enjoyment of cycling. It's better to choose a bike where your child can comfortably reach the pedals and handlebars, and sit upright. An advantage of BikeFlip: when your child outgrows the bike, you can easily flip it for a larger size. See here how our children's bike subscription works.

  • Check the minimum saddle height: Make sure to check the minimum saddle height of the bike to ensure your child can touch the ground with their feet.
