The Stereo ONE22 is deservedly one of our most popular mountain bikes. It's comfortable, versatile and great fun. For the pint-sized Stereo ONE22 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. Wide-ranging Shimano 1x11 gears are both simple to use and legendarily reliable. And we fitted powerful hydraulic disc brakes because, well, you can't put a price on safety. It all adds up to family smiles for miles.
