Sizing Information

Every child is different which is why Frog Bikes use your child's inside leg measurement to help find them their perfect bike. This method is much more accurate than simple age ranges and is easy to measure in three steps:

  1. 1. Stand your child against a wall in their socks
  2. 2. Place a small book between their legs, as high as comfortable
  3. 3. Ask your child to move away, and measure from the top of the book to the floor

Once you have this measurement, use the table below to find the correct bike for your child. This table uses the minimum inside leg measurement for each bike where your child can safely and comfortably place their feet on the ground. Don't worry though as Frog Bikes are supplied with room to grow thanks to their long seatposts.
