At Polygon, we believe every ride is a journey of self-expression and creativity. The Polygon Rudge BMX is engineered to deliver just that—grabbing the crossbar and spinning the handlebars, balancing in various positions, and pulling off a backward flip in midair. Its light and responsive frame gives you the control to showcase your style and turn heads in the park. Whether you’re dialing in tricks, ripping through your local spots, or taking on flatland, the Rudge is your ticket to a ride that makes a bold statement.
