When the bug bites, it's only natural that the mini mountain biker in the family is going to want a bike to match their enthusiasm. The Stereo 240 ONE Actionteam's Manitou J-Unit fork and Radium rear shock – with kids' specific tune – is the one they're going to want. With its 24-inch wheels and perfectly proportioned frame, it's every inch a real mountain bike scaled down to size. That's why we fitted the easy-to-use 1x9 gear system, and powerful Magura hydraulic brakes – so your little shredder is as safe and confident coming down the hill as they are going up.
Frame description Loads of experience goes into every CUBE frame – and the Stereo 240 Pro is no exception. The wheels may be smaller than our other full-suspension bikes, but the attention to detail is just as thorough. We use the same kind of butted-aluminium tubes as our full-size bikes, and apply the same suspension kinematics. There's a replaceable gear hanger so that the inevitable crashes don't result in an expensive frame repair, and it's all passed our strict in-house safety tests with flying colours – so you know it's not just a fun ride, but a safe one too.
Find your size!
Enter your height and inseam below and click on 'Calculate my frame size' to see which size you need. You measure your inseam as follows:
1. Stand barefoot with your heels against the wall. Place your feet about 6 inches apart.
2. Grab a book and place it between your legs, with the short side of the book against the wall. Press the book up against your crotch, mimicking the idea of a bicycle saddle.
3. Measure the length from the top of the book to the floor, the distance you measure is your inseam.
