Improve your everyday with our new PUBLIC R18 Disc. We went back to the drawing board for a totally redesigned flat bar road bike, featuring all-weather mechanical disc brakes, an updated cockpit, and a 2x9 drivetrain to conquer even the steepest hills. Whether you need a light and fast commuter or a versatile bike for any weekend adventure, the new R18 Disc combines high-performance design with modern commuter sensibility.

The PUBLIC R18 Disc offers a light-weight Chromoly frame now with sizes to fit riders from 4’10 to 6’3”.  Spec changes from previous versions include an upgraded Shimano Sora drivetrain with rapid-fire trigger shifters for quick and effortless shifting, all-weather disc brakes that allow you to stop on a dime, an improved commuter-tested cockpit to maximize speed and comfort, and our Premium Sport Saddle designed to give you the same comfort and performance of a well-worn leather saddle on your very first ride.

Design and aesthetics are a top priority for any PUBLIC bike design, and the new R18 Disc is no exception. The frame features reflective, minimalist pinstripes with premium grips and saddle to match, and the removable alloy fenders will keep your work threads clean from the road to the office. We’re confident that this bike is our most premium commuter yet, and perfect for both men and women who prefer the comfort of a flat handlebar without compromising performance or style.
