Knog Oi Prima Bike Bell

The Knog Oi Prima Bike Bell redefines what a bicycle bell should be, combining minimalist aesthetics with powerful performance. Featuring Knog's iconic wrap-around bell design and the latest WAVETEK hammer technology, the Oi Prima delivers a louder, clearer, and more consistent chime while maintaining the sleek, integrated appearance that has made the Oi series a favorite among cyclists worldwide.

The innovative WAVETEK hammer produces a crisp, pleasant tone exceeding 80 decibels, ensuring you're heard clearly in urban traffic, shared paths, and busy cycling routes without sounding harsh or intrusive.

Built with durability in mind, the Oi Prima features a robust hidden spring mechanism and a secure hinged clamp system for quick installation and long-lasting reliability. Thoughtful details, including laser-etched finishing and aerodynamic-inspired contours, make this bell as stylish as it is practical.
