Melbourne, Australia – July 14, 2025 – 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 who are seeking performance and aesthetic appeal, the Oi Prima combines sleek form with refined function to emit a beautiful tone when the hammer strikes. After years of design iterations and rigorous prototyping, the Oi Prima has emerged as a truly perfect 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 for most bikes, the Oi Prima is offered in two sizes and a choice of Anthracite and Primer Grey, and includes an integrated cable management system that discreetly routes handlebar cables, effectively solving 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 tightening.

“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.”
