The New Fuzion SpinnerShark 4-wheel kneeboard is an action packed ride, designed to provide the ultimate ground-shredding fun way for kids to cruise the neighborhood. Featuring inclined rear caster wheels for smooth drifting and spinning, the SpinnerShark makes power-sides, fishtails and 360s easy! Powered by kicking or “pumping,” with a sleek low center of gravity it’s designed for razor sharp steering, maximum maneuverability, and fast paced fun. Its skateboard quality 7-ply real wood deck with custom eye-catching graphic and low to the ground stability combined with responsive hand-controlled steering and dual wheel-braking technology makes SpinnerShark a safe and controlled sidewalk shredding machine.
