Frog Bikes 52 / 20 Inch Kids Hybrid Bike

This 20 inch kids' Hybrid Bike is the ideal multi-purpose, geared bike for 5 or 6 year olds with a minimum inside leg of 52cm. The handlebars can be lowered or raised within a range of 54mm and adjusting the seat height is easy to do at home with the quick release system. This means a Frog Bike will grow with your child making it a great investment.

Made in the UK at our Factory in South Wales, our Hybrid Bikes are perfect for roads, pavements, towpaths and forest trails. They come with mudguards and the option to attach a pannier rack to the frame for transporting school books and sports kit.

Our Bikes inspire children to ride. From the lightweight child-specific frame that is easy and fun to ride to brakes designed for little hands to grab, this all results in a confident bike rider who will jump at every opportunity to get out on their bike exploring.

Wheel Size: 20" inch
