Find their perfect size

Kids grow at their own pace, so we size by inside-leg — the best guide there is. Pop in a measurement (or their age) and we’ll match the right bike.

Not sure? Pick their age

Age is a rough guide — inside-leg is far more accurate if you can measure it.

How to measure inside leg

Measure from floor to crotch for the most accurate bike fit.
  1. Ask your child to stand straight against a wall in socks.
  2. Place a book snugly between their legs.
  3. Raise the book until it sits gently at the crotch.
  4. Mark the wall at the top of the book.
  5. Measure from the floor to the mark.
Top tipMake sure the book is level and pulled up firmly for the most accurate measurement.
