Ridgeback Dimension 20 pale blue
The Ridgeback Dimension 20 is a lightweight and versatile bike loaded with carefully thought out features, specifically designed for younger riders.
A lightweight, triple-butted alloy frame and alloy fork at its heart make the Dimension 20 ideal for cyclists who like to ride more often.
Utilising alloy rims with quick release alloy hubs, stainless steel spokes and fast-rolling Vee Speedster tyres, the Dimension 20 has an all-alloy parts mix to ensure that its weight remains very low.
Other highlights include a reliable Shimano 7 speed gear system with a Rapid Fire shifter to tackle any gradient with ease.
Ridgeback kids bikes offer long term reliability, unbeatable value for money, as well as the necessary durability, to allow them to be passed on to a second child.
Designed to meet the challenging demands of children, a close-up look and a quick test ride of the Dimension 20 will confirm why so many people choose Ridgeback when buying a kids bike.
