Scott Voltage Junior 24 Boys Mountain Bike
A top choice for the young rider not quite ready to go full size, but with enough strength and depth to their riding to take on some proper quality at the heart of their ride. With the Scott Voltage Junior 24 Boys Mountain Bike made to offer a long lasting strength and combine it with a low net weight, you can make sure that your youngster is well equipped to tackle the paths and trails.
Made from a 6061 aluminium for a better response on the road, this is a tough and long lasting machine that's sure to deal with a little mistreatment here and there. With a SR Suntour XCT-JR 24 front fork delivering a better feel, response and cushioning to your little one's ride, covering rougher paths needn't be an issue or cause complaint.
Adorned with quality Shimano components, this bike offers up a 7-speed rear cassette that assures you of a better than ever transmission whilst a front triple chainring delivers a smooth transmission and wide-ranging gearing for covering hills and sharp climbs with ease. Solid wheels specially built for children, this bike is aimed at kids aged between 12-14, and looking for one final stepstone before graduating onto bigger machines.
