Part Exchange Frog Tadpole Union Jack Information

Brand : Frog Bikes


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 you should expect signs of wear and tear. 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.

Start them young, and their possibilities are endless. Whether they become the next Bradley Wiggins, or just grow up to enjoy an active lifestyle, their first bike is the essential cog to their success. We belive that the Frog Tadpole is the perfect first step, and with its great choice of colours, you shouldn't have a problem finding one they love.

Lighter than other balance bikes, the Frog Tadpole is just 4.17kg, and is the main reason the Tadpole is our most popular balance bike. With its lighter weight, the Tadpole is easier and safer for them to control, so the chances of falling are dramatically reduced. The secret to this lightweight is the aluminium frame and components built to the same standards as your very own bike, with no compromises.

Clever features are two to a dozen in the Tadpole. The locking headset that restricts steering movement that helps them learn to control a bike with a safety mechanism built in while the included rear brake allows them to stop much faster - and is kinder to their shoes - than other solutions and includes a adjustable lever designed for small hands.

  • Suitable for Riders Aged 2-3 Years Old With an Inside Leg of 31cm
  • Lightweight Aluminium Frame Built to High Standards With a 5 Year Warranty
  • Clever Features to Make Their Life Safer and More Enjoyable
  • Great Choice of Colours From Bright Pink to Team Sky and Union Jack Inspired Designs

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.
