To celebrate our partnership with EF Education and EF Oatly pro cycling teams, we’re releasing a limited run of our team favourites in podium pink. 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 fits bars 22.2mm and the Large size fits 23.8 – 31.8mm bars.

Handlebar Diameter:

Large (23.8 - 31.8mm)

Small (22.2mm)

Looks and Performs Great

Solid, well built bike bell. Fits great on my road bike bars. It also looks cool which is the real reason to pick one up 😏

Quality bell but not suitable for bad infrastructure

I want to use this bell, it's discreet on the handlebar and I enjoy the nice pingy sound. However, unless your city has good cycling infrastructure and people are attentive to bikes, it's simply not loud enough to break people's bubble and get them to move. I've now switched back to a classic ball-style bell.

Excellent quality

Love my Knog oi.

Unusable - DO NOT BUY

CONS:
- Does not ring reliably due to poorly engineered mechanism
- hard/impossible to ring when riding with thick gloves for winter commuting
- unvonconventionally high ringing sound is not recognized by the elderly as such

PROS:
- looks minimimalistic and cool

DO NOT BUY THIS.

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

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.

‘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.’

Features +-

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.
