CUBE STEREO ONE44 HPC ROOKIE KID'S FS MTB BIKE 2026 DUSTYOLIVE' N 'GOLD

Arguably our most ambitious bike for young riders so far, the Stereo ONE44 HPC Rookie moves the bar for kids' bikes even higher. 

From its perfectly proportioned carbon frame to the 150mm Marzocchi Bomber suspension fork and rear shock, it's a serious bike for having serious fun on the trails. We chose Schwalbe's dependable Nobby Nic 2.4in tyres for their grip and cushioning, complemented by the smooth power of Magura's MT Trail Sport hydraulic disc brakes. And Shimano's 1x12 Deore gears serve up a huge gear range and the peace of mind of legendary reliability. It's a winning combo.
