Ring in a New Era: 80+ Decibel Bell is a Masterpiece of Sound
Knog, the Technically UnKonventional cycling brand known for pushing design boundaries in bike security and safety, today introduces the Oi Prima – the newest addition to the best-selling Oi bell family.
Designed for riders seeking performance and aesthetic appeal, the Oi Prima combines sleek form with refined function to produce a beautiful tone when the hammer strikes. After years of design iterations and rigorous prototyping, the Oi Prima has evolved into a truly refined version.

Oi Prima is completely reconstructed with the development of Knog’s WAVETEK hammer technology, which retains Knog’s unmistakable signature tone. This new hammer technology ensures a loud and consistent ring tone even after 1000s of strikes.

Engineered for seamless integration with most bikes, the Oi Prima is available in two sizes and features a choice of Anthracite and Primer Grey. It includes an integrated cable management system that discreetly routes handlebar cables, effectively addressing a common problem with traditional bell mounts. The Oi Prima’s installation is quick and easy; it simply slips over the bar, requiring only a hex screw to be tightened.

“Most bike bells are like background noise—forgettable. The Oi Prima is the opposite,” said Hugo Davidson, Knog’s CEO. “It’s got personality, a fantastic tone, and looks good doing it. The Oi Prima is a testament to our commitment to creating products that enhance the riding experience while ensuring safety and style.”
The Oi Prima is now available at knog.com and in select retailers worldwide.
