What a bell!

I've been needing a bell for my bike for some time now. Gone are the days of shouting, 'hey!' when passing someone.

The bell looks awesome too and has a great tone and volume.

Not up to quality

I’ve bought two of these bells, they are priced at the high end of any bike bell so I expected top quality and support should there be a failure. Unfortunately both my bells failed quickly with little use, got replaced under warranty and failed again. When I reached back out the second time they did not support replacement of a warranty product? I personally will not be buying any more Knog products, thanks.

So good!

Great design. Easy to attach. Works very well. Looks ghod

'a beautiful design that's just as effective on the road as it is on the trail.'

‘It was easy for us to give the Knog Oi Classic Bike Bell such a high overall score of 9 / 10. It seems to have the perfect combination of features, quality and price making it a great all-rounder.’

What sets the Oi Classic Bike Bell apart?

A beautiful aesthetic, tone & fit make Oi Classic a pleasure to use.

The Sound

The strike of the bell is firm and fast, allowing a good balance of volume and longevity of sound.

The Fit

Just pop it over you handle bar, give the hex screw a quick tighten up, and you’re good to go.

The Mount

Handle-bar cables? No worries. Built into the shape of the mount is a cable management system.

The Look

Where bells usually protrude up or out, Oi doesn’t. It appears to hover around the handle bars.

The Mount

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).

The Look

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

The Sound

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.

The Fit

What about getting it on the bar? Just pop it over, give the hex screw a quick tighten up, and you’re good to go. For handlebars measuring 23.8 – 26 mm in diameter we have supplied a spacer to help the Oi fit snugly and securely to your bars. This can be found discretely tucked into the reverse of the grey packaging insert.
