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

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

Please make sure you know where on your handlebar you are going to place the bell (grips or stem) before you order as you may need a different sized bell.
