Whether they're riding to school or ripping it up on dirt, bike qualities such as low weight and great performance are important for younger riders too. The disc-brake equipped Vertex kids' bikes are ready to help instill a lifelong love of having fun on two wheels.

The Vertex Jr 20 helps kids get rad with a lightweight 6061 Alloy frame paired with a Suntour 80mm-travel suspension fork. A SRAM 9-speed drivetrain with a Rocky Mountain crankset and chainguide add to the bike's capability, especially in rough terrain. Shimano MT200 hydraulic disc brakes provide ample stopping power, while the WTB rims and VeeTire Crown GEM tires roll sturdily and have lots of off-road grip.
