Knog OI Aluminium Bike Bell, Unisex Adult Bell

Very pleased. Louder than others are suggesting. Make sure nothing touches to bell plate (cables etc). It needs to be free to resonate or you get a clunk rather than ring. Large size fitting needed for road bars.

I liked the minimal form of the bell and the sound it makes. It was just a little fiddly to install as it took a while to get the threads of the screw to connect, but once it was on, it was beautiful and currently works well.

Not so load but compact

Gives a very nice resonant "ping" and looks great. Note that the adapter for smaller diameter handle bars is hidden away under the box, I was thinking mine was missing until I was about to throw the box away. This is the Apple of cycle bells.

Expensive but relatively unobtrusive and nice tone.

I love th e design of the oi and bought this version as I thought it would resolve the problem of the 3 standard iOS i’d Bought previously where the hammer’s spring gets elongated and/or twisted After a number of months.... however the luxe has stopped working within a week while the hammer is all ok, the bell seems stuck and all I get is a dull knock rather than the ring it came with. I will be sending back.

Alright but, nice tone but feels a bit cheap. Maybe a bit overpriced. Be cautious if you have brake/gear cables near where you are mounting this on your bars. If they touch the bell it doesn’t work.

Easy to fit and really does the job. Would definitely recommend. Make sure you buy the right size though t fit the diameter of your handlebars.

Tolle Klingel. Lauter, angenehmer Ton. Gute Haptik. Aber leider keine passende Größe für meinen Lenker. Diese ist zu groß, die Kleinere ist zu klein. Wirklich schade.

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.

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

A great bell which is unobtrusive and gives a loud, clear sound. I recommend it.

Pretty good. Very nice and clear sound, and looks good.
