The Scott Roxter 400 in Loch Green is a 24-inch trail-ready kids' mountain bike engineered for young shredders (from 125 cm tall / ages ~8–11) looking to build confidence on technical singletrack and pump tracks. Built on a custom-tubed 6061 aluminium frame finished in an earthy "Loch Green" coat, it features an SR Suntour XCT-JR suspension fork with 50mm of travel tuned with a softer coil spring specifically for lighter riders. Tipping the scales at 10.8 kg (23.8 lbs), the Roxter 400 combines child-specific ergonomics with dependable trail componentry.
Designed with youth control in mind, it features a narrow 19mm grip-diameter handlebar, scaled-down 127mm crank arms, and short-reach Tektro hydraulic disc brakes. Gearing is expanded to an 8-speed Shimano Tourney drivetrain controlled via a RevoShift twist shifter, paired with an 8-speed 11-34T cassette to help spin up steep climbs. High-traction 24x2.2" Kenda Karma2 tires, a stem protection pad, and an included kickstand complete this trail-ready package.
