  • United Motocross 21" BMX Bike

    The United Motocross is engineered for jumping huge gaps, clearing tabletops, for throwing whips and defying gravity whether at the dirt jump trails or at the skatepark. It features full Chromoly (CrMo) frame, forks and cranks, plus, it's kitted out with exceptional aftermarket components from United. This bike also has a 21" long top tube that's ideal for taller riders and those who prefer more space around the cockpit when riding.

    Fast, Agile and Stable Freestyle BMX Bike

    The Motocross BMX takes inspiration from motocross riding and the awesome style of Union team riders. It features trail geometry, giving a stable and smooth performance for fast and predictable control when on the trail and when in the air. Plus, it's equipped with sealed bearings and a collection of quality aftermarket components, making it ready to ride anywhere fast and hard straight out of the box.
