Scott Voltage Junior 20 Kids Mountain Bike
A mean machine in a go faster bright red paint job, the Scott Voltage Junior 20 Kids Mountain Bike is a dirt jumper inspired mini machine made to roll with the trail and keep your little one up to speed with you on joint adventures. Super tough, strong and sure to put up with the mistreatment that your terror can unleash, this bike is the perfect partner for your eager and active child.
Made from an octagon tubed alloy 6061 material for better strength, and a robust construction, this bike is sure to last a long while. Equipped with an SR Suntour XCT-JR 20 front fork, this bike is designed specifically to meet the geometry of children, and with 40mm of travel affording a softer spring setup, this bike is sure to provide a responsive and yet cushioned ride to your youngster.
With a full 7 speed Shimano rear cassette and a genuine Shimano rear derailleur, this bike offers a neat level of gearing for keeping up on cycle paths and maybe taking the odd gravel strewn road. A child-specific crankset and purpose made wheels providing the traction and grip needed, this bike is ready to ride right from the off. Perfect for a child aged between 9-12 or somewhere around 1m in height, this is a great bike for getting out and exploring.
