How to Attach a Minimal Bike Bell
This minimal bell (the Knog Oi) allows you be safe and be heard without the fuss and size of a traditional bicycle bell
Supporting you and your family to SMILE when you ride.
Welcome. Understand if a minimal bike bell will fit on your bike and how to attach your bell. Knog Oi Bicycle Bells are designed to be fitted to standard round bicycle handlebars that range in width from 22.2mm (small) and from 25.4 to 31.8mm (large) in diameter.  This bell is not compatible with aero bars.
Where does it attach Â
Knog Oi Bicycle Bells can be placed anywhere along your handlebar where you have room. Â You need to decide where it will go before you buy your bell so that you get the correct size as some handlebars have different diameters along their length. Â The Oi also has space for cables to run through it.
Once you have decided where it will go work out whether you need a SMALL or a LARGE Knog Oi.
If you are unsure of the diameter of the handlebar you can use a flexible measuring tape and measure around the circumference of the handlebar.
The SMALL Oi bell fits a 22.2mm handlebar diameter (that is a 69.74mm handlebar circumference)
The LARGE Oi fits a handlebar diameter from 25.4 to 31.8mm (that is a 74.77mm-99.9mm handlebar circumference)
What will you receive and what tools will you need
You bell will come in a box and all the components you need will be attached to the bell
What tools will you need? An allen key. A 2.5mm  Allen key
Allen Key part of a multi tool or a coloured allen key set
How does it attach Â
The bells use a simple screw bracket system that clamps onto handlebars.
Remove the Hex Bolt ( screw) using the allen key so that you can open the Knog Oi
Attach to Handlebars:
Manually open the mouth of the mount, and push over the handlebar. If you can, fit it around your cables, there’s a space just for them.
If you have the Large Oi but a 23.8, 25.4, or 26mm diameter bar you’ll need to put the appropriate spacer on your bar to make Oi sit flush. Make sure the gap faces straight up. If your bar is 23.8mm, place the rubber tape provided inside the larger spacer.
Position on a cylindrical part of the handlebar that you find comfortable, but is not curved or tapered We think close to the handle/grip, so your thumb can comfortably flick the hammer
Screw in the hex bolt, firm enough to prevent any rotation, but don’t overtighten (this can affect the sound quality).
Check that it works: Simply flick the hammer and enjoy the magical sound of your ringing bike bell. Learn a bit more about appropriate use of bike bells in our story Be Heard with a Bike Bell
Things to watch out for Â
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).
