Get the attention of everyone on the road when you use the Knog Oi Minimal Bike Bell. Just like shouting “oi!” this bell keeps you safe while you share the road. However, rather than a loud and clunky sounding bell, the Oi Bike Bell offers a beautiful almost melodic tone. This is sure to make you stand out even more than traditional bike bells. In addition to its audio ability, the Oi Bike Bell remains sleek and minimal on your handlebars. It fits a variety of bars measuring 23.8 to 31.8mm in diameter. This includes drop bars as well as cruiser and commuter bikes. Coming in black, silver, brass, and copper, the Oi Bike Bell enhances the look of your bike. Unlike other bells, this one seamlessly integrates the second you install it.
