Knog bell clamp broken already just put on bike

Very disappointed in this bell the plastic clamp is very brittle and has snapped after a couple weeks on the bike I put it on and left it didnt move it came back 2 weeks later to a loose broken knog bell

Love Knog

Great well designed products, love using them with the GoPro mount to sit neatly under our Garmin. The lights work well, we have used them for years, very reliable, no issues in rain.

sound great

So musical I can't wait to pass someone!

Great bell!

This is my 2nd bike with the Oi bell. I like the sound and the simple design. It's also quite rugged.

Plastic band broke while installing

'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.
