Knog Oi Bicycle Bell Large 23.8mm - 31.8mm ZIL-200

The oi bell shape originates from its house - the handle bar. Our design team explored hundreds of iterations in style design. Then different widths, depths, materials, curvature, actuators, springs and more were tested and prototyped to achieve the optimum design.

APPEARANCE

The bells usually pop up or out, Oi is not. It looks like it's hovering around the handle bars. In a way, it's prudent. But in another, it stands out as unrecognizable.

We tested countless prototypes to achieve the perfect pitch, length and volume. With a spring-loaded actuator mounted on it, the chime's beat is solid and fast, providing a good balance of sound and long-lasting sound. The cymbal actually has several pitch sounds - a core and a few supporting higher pitches, ensuring that it can be clearly seen or not. To compare it to a musical instrument in which some cymbals play a single note, Oi plays a chord. Listen for yourself here...
