KNOG Oi Prima Bike Bell - Anthracite

The Knog Oi Prima Bike Bell reimagines the traditional bicycle bell with a sleek, wrap-around design that sits neatly on your handlebars. Combining Knog’s signature minimalist aesthetic with innovative WAVETEK hammer technology, it delivers a crisp, clear and pleasantly resonant sound in a compact package

Whether you're commuting through the city, cruising along shared paths or exploring gravel roads and trails, the Oi Prima is a stylish, practical bicycle bell designed to help you alert pedestrians and fellow riders without cluttering your cockpit

A Better Sound with WAVETEK Technology

At the heart of the Knog Oi Prima is its innovative WAVETEK hammer, engineered to produce a louder, crisper and more consistent chime than a conventional small bell design

The carefully designed hammer and striking surface create a clear tone that's intended to be noticeable without being unnecessarily harsh. It's a thoughtful upgrade for cyclists who want a discreet bell that still makes its presence known

Minimalist Design That Fits Your Cockpit

The Oi Prima features Knog's distinctive wrap-around handlebar design, with a streamlined silhouette, refined tapered edges and detailed finishing

Its low-profile shape integrates neatly into your bike's cockpit, making it an excellent choice for road bikes, gravel bikes, commuters and custom builds where every component contributes to the overall look

A considered cable-management design also helps the bell sit neatly alongside your handlebar setup

Built for Everyday Riding

The Oi Prima isn't just about looks. Its hinged clamp system makes installation straightforward, while the robust spring design is engineered for long-lasting use

Choose the Right Size for Your Handlebars

The Knog Oi Prima comes in two sizes to suit different handlebar diameters. Check your handlebar diameter before ordering to ensure the correct fit

• Small: Fits 22.2mm diameter handlebars

• Large: Fits 23.8–31.8mm diameter handlebars and includes shims for fitting flexibility

Please note: The Oi Prima is not compatible with aero handlebars. Check the available mounting space and cable position on your bars before purchasing.
