Part Exchange Frog 55 Kids Hybrid Bike Team Sky Information

This is a pre-loved, part exchange bicycle. The bicycle will be fully inspected by our experienced mechanics prior to despatch to ensure it is fully working, however please be aware that this is a used bicycle and as such you should expect signs of wear and tear (which will vary from bike to bike). While the original manufacturer’s warranty will not apply to this cycle, we will resolve any genuine manufacturing failures that occur within the first three months of purchase.

Adventure awaits them. Set them free on their very own Frog 55, a light aluminium bike that is both safe and easy to control, and fun creating.

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.
