How to choose the size of a kid’s bike

In contrast to many kids’ bikes, Frog bikes are sized by the leg length rather than age, as this is the most reliable way of getting the right size of bike for each child. Age alone isn’t a reliable measure as there is a large spread of “normal” leg lengths & heights for each age.

Please take the time to measure the rider’s inside leg.
It’s easy to measure:

  1. Stand the child on shoes ont the toes against a wall
  2. Place a small book between their legs, as high as is comfortable
  3. Ask the child to move away and measure from the top of the book to the floor.

Based on my experience, I only measure the inseam to determine the size.

f course all children have different length arms and torsos too, so to ensure a comfortable riding position, the handlebar height can be tailored, and saddles can be slid backwards and forwards on their rails. (These adjustments are easy to do and just need an allen key; instructions are in the manual).
