The bicycle bell has finally entered the 21st Century. No longer just a domed shape that lets off a shrill ring, the Knog Bicycle Bell was designed by a small team of engineers and industrial and graphic creative types to be shaped like an Oi and sound like an angel playing a glockenspiel. Discreetly placed to hover around almost all cylindrical handlebars, the Oi doesn't protrude out. The bicycle bell has grown up and is ready for you to give it a ring.
