Frog Bikes 40 2021 14 Inch Hybrid Kids Bike Red

5 out of 5 Customer Rating

The Details

The key thing that makes the Frog 40 so popular is the light aluminium frame which results in a minimal 6.3kg weight. This lightweight bike is much easier for them to control leading to a much more enjoyable experience. It is also easier for you to carry! The build quality is top-notch and is backed by a 5-year warranty, ideal if you're planning to hand it down.

Keeping them safe and balanced are a selection of smart features like a locking headset that prevents them over steering, preventing any chance of them going over the handlebars due to a mistake. The dual brakes are powerful and come equipped with levers designed for small hands.

  • Suitable for riders aged 3-4 years old with an inside leg of 40cm
  • Lightweight aluminium frame and forks built to high standards with a 5-year warranty
  • Includes a bell, mudguard, reflectors, and 2 year component warranty

One of the biggest temptations is to buy a bike your child will "grow into". However, this is likely to have the opposite effect and put your child off bikes and cycling altogether! The data obtained during our child-specific frame design research has been used to produce a helpful sizing app. Ask in your local store about our FrogFit app to get the best-sized bike for your child.

Another common mistake is to purchase a budget bike but these models are often as heavy as the child and lead to frustration at not being able to cycle. Our lightweight bikes are a great confidence booster and can also be used as a balance bike for a taller child by removing the pedals.

Our most popular first bike and for good reason.

Our Verdict

Frog's 40 combines a great frame and component selection with safety features to make their first experience enjoyable. Plus a great range of colours makes finding one they love easy.
