Knog Oi Classic Bell


The Knog Oi has revolutionized the bike bell market. Bells tend to look bulky and sound harsh but the Oi features a sleek, discreet design with a perfectly pitched, effective ring. The Knog Oi Small is suitable for handlebars with a diameter of 22.2 mm and the Knog Oi Large fits handlebars with diameters from 23.8 to 31.8 mm.


The Oi bell’s shape originates from its home – the handle bar. Where bells usually protrude up or out, Oi doesn’t. It appears to hover around the handle bars. In one sense, it’s discreet. But in another, it stands out as unrecognisable.
