Knog Oi Luxe Bike Bell – Sleek Low Profile Bicycle Bell for Adults, Durable Metal & Vegan Leather, Clear Tone, Easy Install for Flat Bars & Drop Bars (Small 22.2mm / Large 23.8–31.8mm)

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.

First one was missing the hex screw. But they sent a replacement immediately and it works great. Such a sleek design.

There's a lot to love about the bell. It's sleek. It's easy to install. It looks great. The sound is loud and distinct... when it works. Unfortunately, it's finicky and on some bikes. On my road bike, my cables run along my handlebar and ever so slightly touch the bell. That is enough to dampen the ding. To use it "effectively" I have to wedge my finger under my cable to move it away from the bell and then ding it with my thumb. Not convenient. Unfortunately, there aren't any good adjustments to mounting it on my road bike. It works great on my gravel bike, though. I wanted to love it. It would be perfect if it didn't have this drawback.

Looks great and the design is really sleek and well made. Fit on the bars was solid and the bell sound was clear and easy to trigger. Unfortunately the spring trigger bar flew off after hitting a bump, which made it useless. Tried contacting the company and got no response regarding the issue.

tl;dr The large luxe version is plenty loud with a pure, cutting tone. I love it! The one to get is definitely the large luxe. I've read professional reviews indicating that the small luxe bell suffers from a design flaw, that the striker will bounce and dampen the resonance. The result is an unimpressive thunk! sound. The classic bells, both small and large, use a plastic striker that doesn't peal as strongly as a metal strike, nor is it as durable. Customer reviews on Amazon tend to align with these pro reviewers, as the more unfavorable reviews tend to correspond to the classic and the small luxe. Best to sick with large luxe only. In any case I have two other cheapo bells, both with plastic strikers. The Oi Luxe is louder with a longer ring than both. Before receiving my Oi I watched Knog's promo video in which installation was demonstrated. The video warns against driving the screw so far that the top and bottom of the ring meet. Space must be left to allow the top of the ring to resonate. In order to achieve this gap with a firm mount on my 25.4 mm handlebars, I used both the plastic shim and the adhesive rubber strip (both included), even though the instructions only demanded the rubber strip for 23.8 mm bars. I will not be contained! *rips shirt off*

I'm somewhat apprehensive that actually mounting this on my bike, the quality of the Bell part is acceptable but the spring inside the striker is somewhat sticky and doesn't easily strike.. this is one issue that I have with it's loudness, it's Hit or Miss depending on how hard you hit the striker, like I said sometimes it binds up and doesn't ring as loud as it should!! At $30 you would think this would be in better working order versus a cheap $10 bill.. I only purchased it because I wanted to put it on a road bike and really wanted a narrow bell, unfortunately this is an acceptable. It seems easy to install and it's weight isn't bad at all

If you know what you are doing when installing the bell it works fine. Looks great on my Fast Ripper named GOLDIE

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 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.

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.

Der Klang der Glocke ist gut, laut genug und klar. Man kann auch mehrmals hintereinander Leuten. Die Verarbeitung und die Qualität ist hervorragend und sein Geld wert. Jetzt hoffe ich, dass sie lang genug hält und sich der Preis bezahlbar macht. Ein Manko ist die Befestigungsschraube. Leider ist die für mein Rennradlenker 30,8 mm um ca. 2-3 mm zu kurz. Ein guter Zug vom Herstellers wäre, eine längere Schraube als Alternative bei zu fügen. Ich habe zum Glück ein großes Sortiment an Schrauben um das Problem zu beheben. Eine passende Schraube (M3) hat nicht jeder sofort zur Verfügung um den Klang dann zu genießen.
