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.

Great for morning rides
by Jeff of Minneapolis, MN on December 30, 2019
Product:
Knog Oi Bell Aluminium - Black Bells: Large - Black
Ownership: more than a year
Tech Knowledge: average
Pros
A polite chime that announces my approach on the path. Very peaceful for morning rides.
Other Thoughts
Riding through the city during lunch hour? No one will hear this bell. I do love this bell so I am not knocking it, just a heads up to consider your riding style. Also on gravel/rough terrain it will resonate faintly from the vibration. I still prefer this to other style bells.
