The Oi bell's shape originates from its home - the handle bar. Our 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 unrecognisable.
We tested numerous prototypes to get the perfect pitch, length ofring, 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. Our bell actually has several pitch tones - one core and several supportive higher tones to ensure it's unmistakable and safely heard. To compare it to a musical instrument, where some bells play a single note, Oi plays a chord. Hear it here for yourself...
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 (for the organiser inside us all). 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.
For handlebars measuring 23.8 - 26mm in diameter we have supplied a spacer to help the Oi fit snuggly and securely to your bars. This can be found discretely tucked into the reverse of the grey packaging insert.
