The high-carbon steel frame on this orange mountain bike ensures that it is durable and the suspension fork has comfortable shock absorption for a comfortable ride. It also has a 21-speed derailleur which means that there are 3 gears in front and 7 in the back so that you can use it to tackle any terrain. It has 4-inch mountain tyres which are fat and knobbly and will easily roll over anything in their path. They can easily cope with rough hills and gear changing is smooth as well. It can fold easily too using a quick-release clamp to store it or fit it in a car. For ages twelve years and above.
