From the manufacturer
The Oi Small
The Knog Oi is available in two sizes, large and small. The large fits 31.8mm bike bars and the small fits 22.2mm bike bars.
The Oi Bell
Redefining the Bike Bell
With a standout design that tucks stealthily close to your bars, the Oi is a unique way to add some noise potential to your bike. Knog has removed everything that has contributed to the dusty image of bicycle bells and replaced it with an innovative bell that projects a bright, crisp, ear pleasing sound, all while hovering cleanly around your handlebars. The aluminum surface of the Oi is available in 4 different color variations.
- Stainless Steel, High Tensile Spring
- Aircraft Grade Aluminum Ringer
- Reinforced Nylon Mount
- M4 Hex Screw Tightener
The Oi bell's shape originates from its home - the handle bar. Knog’s design team explored hundreds of iterations in designing the style. Then tested and prototyped different widths, depths, materials, curvature, actuators, springs and more to get to the optimum design. 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 unrecognizable.
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. What about getting it on the bar. Again, not a thing. Just pop it over, give the hex screw a quick tighten up, and you're good to go. No sliding down the handlebars, no dismantling and re-assembling.
Clear, Cutting Sound
Knog tested numerous prototypes to get the perfect pitch, length of ring, and volume. 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. The bell actually has several pitch tones - one core and several supportive higher tones to ensure its unmistakable and safely heard. To compare it to a musical instrument, where some bells play a single note, Oi plays a chord.
Refusing to conform to anyone or anything
Knog is out there every day smashing the main roads, rolling softly through the back country and being attuned to global sub-cultures which is the source of Knog’s inspiration. It's what drives them to consistently deliver fresh and innovative products that enable riders, walkers and urban adventurers around the world to discover their own sense of freedom, have fun, and live in the moment.
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.

I love the design of this bell, but it is just about useless to me. On road rides, cruising at 15 mph the bell is virtually inaudible to riders more than 8 feet away. I believe this is because the bell is lower frequency and does not have a punchy ring when hit with the striker This seems to cause the ring to get lost in background wind noise. Add to this the suspension of the bell itself is very springy. So much so that on a reasonably rough road surface the bell is constantly making a little ding.ding.ding.ding.ding noise. You also have to be very careful to keep your hand away from the bell because any contact will mute it almost completely. The cable relief in the band is a neat feature, and is one of the reasons I bought the OI brand. However, if your cables come out of the tape on the front of the bar instead of the bottom the bell striker will be rotated very far down on the bar. Due to the design this is fixed and cannot be adjusted on the bell...
After noting the constant dinging on a semi-rough road I'm not even going to try it on the mountain bike....
Pros: Really slick look
Cons: Not loud, Have to be careful where you touch it, Cable routing can cause bell to be forced into position where it is difficult to use, Minor vibrations cause bell to make noise.
30 mph by the Navy yard I'll give an unaware pedestrian a "yo" at 30 yards. No bell is as good as the voice when you're really moving. Even at 15-20 mph pedestrians who love to stand or step in front of one in the bike lane seem to respond better to a voice. This little bell is a sweet piece of design though. I approve. As for those who say it chimes inadvertently, I find it only tinkles a bit over railroad tracks, grated drawbridges, and the occasional pothole or steel road plate.
I went a long time without a bell, decades really, because I could not stand the looks of the cheap chrome things most bike shops push on their customers. Bulky, ugly, easy to destroy in a fall, they quickly become pitted and rusty in a single season of riding. The Oi Bell is none of that. You will barely know it is there, clipped around your bars, until you need it. I find myself ringing it sometimes just for the sake of hearing it.
The lever is flimsy, but we're adults and can handle it.
The ring sounds like something is touching the aluminum ringer, severely muffling the ring and introducing other sounds (not a "pure" ring as in the video)
The quality of the plastic is VERY good, and seems very durable, as is the clamping mechanism, and does not have to be very tight to hold firmly.
Did I say that it's pretty? I really wanted this as I do not like the look of a bell shaped tumor on my handlebars...
I compared this to: https://www.amazon.com/gp/product/B018J4EIQU (same pitch but without all of the above caveats)
Buy this if you care 90% bout looks and 10% about volume
