Balance Bike Sizing Chart

Choosing a balance bike that fits your child - When searching for a balance bike for your little rider it's always important to choose the correct size. Not choosing the right size can frustrate your child and inhibited their ability to learn and it can also be dangerous. Most likely it's their first bike and we highly recommend that you purchase a bike that fits them now, not one that they will grow into.

1: Measure Your Child's Inseam

Measure Childs Inseam

Getting a proper fit on a balance bike requires a key measurement, your child's inseam measurement. There are two easy ways to accomplish this:

  • Select a pair of their best-fitting pants and measure from the crotch to the bottom. The number of inches, to the nearest half-inch, is the inseam length.
  • Have them stand in their stocking feet with their feet slightly apart and back flat to a wall. Measure the length/distance between the floor and their crotch.

3: Bike Weight

A simple rule to follow when selecting a balance bike. A balance bike should weigh no more than 30% of your child’s weight. An easy way to determine this is to follow a simple calculation:

(child's weight) x (0.3) = (max bike weight in lbs)
i.e. 25 x 0.3 = 7.5

Using the above example, if a child weighs 25 lbs and we calculate this by the rule of 30% then their balance bike should weigh no more than 7.5 lbs.

Extra: Helpful Tips & Factors To Consider

  • Buy for the now and not for the future. A bike that is too big for your child might lead to overall frustration and impair their ability to learn to balance on a bike.
  • If your child is 3 years old, most 12" bikes will fit them just fine. For children 2 and under or children over the age of 4, measure carefully.
  • You want your child to be able to step over the frame of the bike and have their feet firmly planted on the ground while sitting on the seat.
  • To allow room for growth, it is ideal to purchase a bike with a maximum seat height of at least 2″ above the child’s current inseam.
