Bike bells generally look & sound a bit ugly. But why? What if they looked sexy & sounded like an angel playing a glockenspiel? A bell with a beautiful tone, but also a remarkable style and choice of materials that embodies a rider’s personality. The Small Oi fits 22.2mm bars e.g Mountain bike…


Aluminium Bike Bell KNOG Oi

With a standout design that tucks stealthily close to your bars, the KNOG Oi Aluminium Bike Bell is a unique way to add some noise potential to your bike. Knog has removed everything that has contributed to the dusty image of bicycle bells and replaced it with an innovative bell that projects a bright, crisp, ear pleasing sound, all while hovering cleanly around your handlebars. The aluminum surface of the Oi is available in 4 different color variations.

Innovative Style

The Oi bell’s shape originates from its home – the handle bar. Knog’s 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.

Cable Management

What about the handle-bar cables? No worries. Built into the shape of the mount is a cable management system. So not only does it allow the bell to look and sound uninterrupted, it also helps gather your cables. What about getting it on the bar. Again, not a thing. Just pop it over, give the hex screw a quick tighten up, and you’re good to go. No sliding down the handlebars, no dismantling and re-assembling.

Clear, Cutting Sound

Knog tested 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 its unmistakable and safely heard. To compare it to a musical instrument, where some bells play a single note, Oi plays a chord.
