I wanted a bell that would blend into my handlebars without being an obvious dome plonked on the top. This is very subtle, and stylish. Mine is black and it blends with then handle bars. The ring tone is nice, not at all piercing. It is not the loudest sound, but car drivers aren't going to hear you anyway. Pedestrians and other cyclists can hear it well.

Previous bells have been both ugly and unreliable. Style is a subjective opinion but I find the Knog Oi to be beautifully minimalistic. With just one moving part, I expect it will prove to be reliable as well. And its remarkably small size allows me to place all my handlebar accessories in close proximity. Two warnings for prospective buyers: 1) ensure that cables are not touching the bell as that will dampen the sounds of the bell and 2) the small version of the bell will only fit extremely small handlebars. I initially purchased that model which Amazon thankfully allowed me to exchange.

I'm a former QA manager so stuff like this irks me. Initially, I liked the design. Low profile, and nice design aesthetics. Clearly they prioritized form over function and didn't do any testing. The first flaw is the design of the clamp. DO NOT PUT THIS ON A CARBON FIBER BAR. That's asking for trouble. The back of the clamp applies asymetric pressure which could potentially damage a carbon bar... but probably not becuase you could never mount the thing on a standard 31.8 mm carbon bar because the clamp is not large enough. Yeah, pretty big oversight, advertise it fits a 31.8 mm bar and then don't provide a screw long enough to reach the threads. I got my digital calipers and measured my bars, yup, 31.8. They're Zipp Service Course SL-70 XPLRs. If you pull the bell on to the bars as snug as possible, and make sure everything is perfectly aligned, the screw isn't long enough to grab the threads (let alone be properly secured). I tried it on two different pairs of 31.8 mm Bontrager bars, as well as a 3T Superergo. Nope, nope, and nope. The other problem with the design of this bell is that the resonance is dependent upon the front clamp maintaining a very specific arc. When you put the bell on a 31.8 mm bar, it changes that arc and mutes the bell so that instead of a diiiiiiiing, you get (plink). Great aesthetics, horrible execution.

Es verdad lo que comentan otras reseñas, es un timbre muy caro, muy bonito y que suena fatal. No sé si entra en resonancia y se neutraliza el brillo o qué, pero es un timbre inútil.

Una bella pieza muy bien maquinada y el sonido sumamente agradable...Vale la pena pagar el precio.

People complain this bell isn't loud enough.Well, I can't speak for the "original" but definitely the Luxe model with the metal striker makes a very solid, resonant ding. And the unique compact design is just great for the limited space on my drop bars. It does only mount in one orientation (I would prefer it flipped upside down because of where the cables are routed on my handlebars) but I was able to get it to work just fine. For sure you need to set it up so nothing's rubbing and deadening the sound but this should be possible on pretty much any bike, just order the right size.One minor (and surprising) issue -- and if you go to the Knog website and watch their video about the time they invested in designing the bell, about testing all different pitches and tones until they found the absolute perfect one, you'll laugh -- but these geniuses have either intentionally replicated the iPhone notification "ding" tone, or else it subconsciously seeped into their brains and they mimicked it by accident. Well, the only problem with that is, people don't necessarily realize you're a bike, and not a phone! So, it kind of necessitates a double-ding if you don't want to sound like a jogger who just got a text.

The best reason to buy this bell is for aesthetic purposes and because you can easily position it where you need it on your handlebar. The first one I bought broke after a year so I upgraded to the Luxe Oi. The Original Oi bell has a spring holding the hammer head. This spring is a compression spring about the quality you would find in a ball-point pen. Eventually, even with light use, it will fail and become unreliable. The luxe uses a hammer with what looks like a tension spring. This holds the hammer in alignment and should work for much longer. If you like the deisgn then buy the Luxe.The other issue is loudness. It's not a quiet bell but its no louder than an average bike bell. The larger Oi seems to ring more loudly at a lower frequency and the smaller Oi luxe I have rings less loudly at a higher frequency. I wouldn't expect people to hear it more than 20 ft away from you. On a hybrid bike doing my light commute, this is acceptable. On a road bike doing 20 mph, this bell won't give pedestrians enough time to react. I doubt any bell solution is appropriate for that scenario. I have an Incredibell and that is significantly louder (maybe 30 ft) but I think the preferable solution is an electric bike horn if you have serious needs.The bell is suspended on compression springs. I don't think this will fail with use but I could rip or deform the head of the bell easily with my fingers. THis is not a likely point of failure due to its low profile. Still, I can see how an MTB user might want it to be even more robust. But the fact a bell is functionally a thin piece of vibrating metal means most bicycle bells I've seen are fragile.I've bought two now. I like that it's compact but if you have explicit needs then you should look elsewhere. Don't kid yourself; No bell is going to be heard by pedestrians much less cars on rush-hour city streets. Either learn to bellow or get a horn.

I love this bell, very stealth like and I like the positive feel to striker. I had to install it the opposite way to what it should be because the cables were touching the bell and stopping the bell from ringing, this might be an issue for some but works well for me, I could have swapped things around on my bar but couldn’t be bothered.The only down side is the cost! It’s expensive and in my opinion a little over priced for a bicycle bell but saying that I would buy another.

Die Knog Oi Luxe Fahrradklingel ist für mich die derzeit beste Fahrradklingel auf dem Markt. Zugegeben sie Sie ist nicht billig, aber jeden Cent wert!Sie wird in einer schönen Box inclusive eines Inbusschlüssel zur Befestigung geliefert. Die Montage ist innerhalb 1 Minute erledigt, da weder Bremsgriffe oder Schaltung demontiert werden muß. Die Montageschelle ist schön massiv und nicht ein billiges Metallband. Die Befestigung erfolgt mit einer Inbusschraube. Sie besitzt ein sauber gefertigtes Veganes Lenkerpolster um Kratzer zu verhindern. Gegenüber dem Vorgängermodell wurde der Klingelgeber wesentlich verbessert, was zum einen das Handling verbessert und zu einer längeren Haltbarkeit führen dürfte. Der Klangfarbe meiner Oi mit Messingkörper ist sehr angenehm. Sie klingt laut, sehr klar und schwingt langanhaltend aus,..kein billiges Alugeschepper. Sie passt mit ihrem dezenten Design zu jeder Art von Bike, und bietet sich auch als wunderbares Geschenk an. Für mich ist die Oi Luxe was Design, Verarbeitung und Klang angeht die Königin der Bikeclock,..dafür gibt es ohne wenn und aber gerne 5 Sterne.
