Sizing Information

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 in socks 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, in inches.

Once you have measured the inside leg, use this table to find the right size of bike for your child. Note we give the MINIMUM inside leg length for each bike, with the saddle at its lowest setting. At this height, the child will safely and comfortably be able to get their feet on the ground. Don’t worry - Frog Bikes have long seat posts, so the saddle can be raised a long way as the rider grows.
 

  Minimum inside leg in cm (in) Approx age Wheel Size Frame Size
Tadpole 32cm (12") 2-3 12"  
Tadpole Plus 38cm (15") 3-4 14"  
Frog 43 43cm (17") 3-4 14" 9"
Frog 48 48cm (19") 4-5 16" 9.5"
Frog 52 52cm (20") 5-6 20" 10"
Frog 55 55cm (22") 6-7 20" 11"
Frog 62 62cm (24") 8-10 24" 12"
Frog 69 69cm (27") 10-12 26" 14"
Frog 73 73cm (29") 12-14 26" 16"
Frog Road/Track 58 58cm (23") 6-7 20" 11"
Frog Road/Track 67 67cm (26") 8-12 24" 14"
Frog Road/Track 70 70cm (27") 11-14 26" 17"

Of 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).
