The Stereo 120 is deservedly one of our most popular mountain bikes. It's comfortable, versatile and great fun. For the pint-sized Stereo 120 Rookie we took all these traits and packaged them in a kid-friendly size for your junior trail explorer. The easily adjustable Suntour air suspension adds both comfort and control. Shimano's wide-ranging 1x12 gears are both simple to use and legendarily reliable. And we fitted Magura's powerful hydraulic MT Thirty disc brakes because, well, you can't put a price on safety. It all adds up to family smiles for miles.
Frame description
We don't pull punches with our kids' range. The Stereo 120 Rookie features exactly the same kind of hydroformed frame tubes as our adult bikes, carefully honed into two perfectly proportioned smaller frame sizes. The short linkage, covered pivots and smooth suspension kinematics are straight from the renowned Stereo 120's playbook. Internal cable routing reduces maintenance downtime, and we fitted a replaceable gear hanger in case of accidents. Your young trail explorer is going to be stoked on this...
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.
