Ridgeback Dimension 20 deep red
The Ridgeback Dimension 20 is a lightweight, 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 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, and the necessary durability to pass them 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.
