Knog Oi Prima Bike Bell

The Knog Oi Prima is a stylish, low-profile bike bell that sits flush against your handlebars and delivers a clear, melodic ring. A redesign of the modern bell classic — slim, elegant, and built to last.

Why Oi Prima

• Minimalist design — sits flush against the handlebar so it doesn't get in the way of brakes, shifters, or lights
• Clear, melodic ring — far more pleasant than the typical "ding"
• Aluminum construction for durability and a refined look
• Easy to fit on most modern handlebars
• Available in multiple finishes to match your bike's aesthetic
