Oi Bicycle Bell

The Knog Oi Bicycle Bell's shape originates from its home - the handle bar. The design team explored hundreds of iterations in designing the style. Then tested and prototyped different widths, depths, materials, curvature, actuators, springs and more to get to the optimum design. Where bells usually protrude up or out, Oi doesn’t. It appears to hover around the handle bars. In one sense, it's discreet. But in another, it stands out as unrecognizable. It has been tested with numerous prototypes to get the perfect pitch, length of ring, and volume. With a spring-loaded actuator built into the mount, the strike of the bell is firm and fast, allowing a good balance of volume and longevity of sound. The bell actually has several pitch tones - one core and several supportive higher tones to ensure it's unmistakable and safely heard.
