Is the Knog Oi Classic Bell the Best Bike Bell Made?

The Knog Oi Classic Bike Bell threw out the rulebook on what a bike bell should look like and started over. Rather than clamping a dome to your bar, the Oi uses a cast aluminum ring that wraps directly around the handlebar, letting the bell hang below and ring with a tone that is clear, rich, and completely unlike the tinny rattle of a standard bell. It is award-winning design from Australia, and the Copper finish brings a distinctive warmth and character that makes it one of the most visually striking accessories you can add to a bike.

The Large size is compatible with handlebars from 23.8 to 31.8mm, which covers modern road, gravel, and mountain bike setups. Installation is tool-free and takes under a minute. The Copper colorway suits vintage-inspired and custom builds especially well, pairing with brown leather saddles, gold hardware, and tan-wall tires for a cohesive, intentional aesthetic from stem to stern.
