Oi Classic

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 Large Oi fits 23.8 to 31.8mm bars e.g. drop bar road bikes and some cruiser / commuters.

The Small Oi fits 22.2mm bars e.g Mountain bike (near the grips), BMX & some old commuters.

Please use the guide below, or ask your local Knog dealer if you are unsure which size is suitable for your bike.

If you don’t know which sized bell you need, then check out this bell mounting video for further help or this how to measure your handlebar guide.
