Cube Stereo 140 Rookie 2023 27.5" Kids Bike

Available with Cube in the sizes shown above. Expect delivery within 8-9 working days of placing an order.

Packaging great performance, low weight and safe-but-fun handling into a smaller frame isn’t always easy, but we love a challenge.

The Stereo 140 HPC Rookie’s frame combines 140mm of refined suspension kinematics with perfect proportions – in two sizes – and all the advantages of our advanced carbon construction.

We added a replaceable gear hanger in case of accidents, and the internal cable routing keeps gear shifts cleaner for longer. It’s the complete, pint-sized all-mountain package.

Arguably our most ambitious bike for young riders so far, the Stereo 140 HPC Rookie moves the bar for kids’ bikes even higher. From its perfectly proportioned carbon frame to the 150mm Marzocchi Z2 suspension fork and Fox Float DPS Performance rear shock, it’s a serious bike for having serious fun on the trails.

We fitted a Newmen Evolution wheelset for its combination of low weight and durability, complemented by the smooth power of Magura’s MT Thirty hydraulic disc brakes. And Shimano’s 1×12 Deore transmission serves up a huge gear range and the peace of mind of legendary reliability. It’s a winning combo.
