Made in the UK at the Frog factory in South Wales, Frog 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.

Frog 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.
