Big setback!
Very disappointing quality. Nice design, but barely functions and does not do what it is meant for. A waste of money.

Good-quality unobtrusive bell with pleasant sound
Well audible but not irritating to other traffic. All parts are coated so I expect a somewhat longer lifespan than previous purchases.

This is already the 3rd knog OI I buy. Ease of use, clear sound and not really visible on the bike. All my bikes now have these seated.

The bell that doesn't look like a bell

Super product
For use on a mountain bike. Perfectly integrated into the shimono Xt brake handle. Perfect for mountain biking. On the road, in traffic, the sound is a little too weak if we have to find a negative point.

Fine bell in rotten place though
Rings loud, but unfortunately has to be mounted close to my handle because near my cables where it should really then it does not ring .

Was hesitating because of the reviews that it would not be loud enough. But the bell has a fine volume in my opinion, so don't let that put you off

Beautiful design and loud sound
Very nice bike bell that actually does not stand out on your handlebars at all. The sound is tremendously loud, making it easy for other cyclists to hear you.

Beautiful minimalist bell
Despite reading here and there that the spring feels a bit fragile and/or breaks off, I wanted to give this bell a chance. I had a similar bell from another brand which gave really lousy sound. This bell at least gives good sound and is much better and nicely finished. It is hardly noticeable and that was exactly why I bought this bell. I wonder how long it will last, but so far I am very happy and satisfied with it!

Does what it is supposed to do: ring
Meets expectations. I previously had the Knog Oi Luxe but the spring is already broken. This one seems a lot more solid and cheaper.
Pros & Cons

Too soft
This bell looks nice and takes up little space on the handlebars. But the controls are as broke as 2.50 bells at Action and more importantly, the sound is way too soft.

Delivered well and quickly. Easy to install.

Fine, improved and now also loud
My second Knog Oi, the first one lasted for years and also still serves on another bike. Bought a new one, this one is clearly louder (it says something about it on the package) and that's an improvement because the first one was not always easy to hear. Although sometimes this is also due to the ears of my fellow cyclists. I am happy with it.
Pros & Cons
5 / 5
Nice little bell. Takes up hardly any space on the handlebars.
Nice little bell with good sound. I've had more bells that didn't work with gloves on, this one does. It comes in handy when you are in the woods on your mountain bike warning hikers that you are coming.

Nice design, but poor quality.
The spring of the bell is of poor quality, after half a year and not such high use it is already bent making the bell unusable.

Top product, happy with the purchase
Also on the road bike you need to be audible and with this bell fellow road users hear you coming fine. Well helped by employee of mantel rotterdam. I like to come there even if it is sometimes for the good coffee.

Top bike bell!
If you had ever said, I would spend more than a few euros for a bike bell, I would have called you crazy, but this little inconspicuous, surprisingly loud bike bell is worth every penny!

Correct
easy to install, very light, to be seen over time. after a while I find that you can't hear the doorbell all that well (in the middle of Paris, for example).

Nice thing but very dependent on your bike whether it works at all
Nice design but on my Giant Contend SL this bell simply does not work. There is not enough room through the cables for free operation and on the ribbon does not work.

Nice bell, good sound
Nice bell, fits well on handlebars, hardly noticeable and rings well! Good sound. With my previous bell only after 2 years the little hammer broke off. Hopefully this one will last longer.
Pros & Cons

Broken after 2 days, far too fragile
The bell broke after the second day. The spring is very fragile and bent very quickly. And the button at the end of the spring dislodged. The doorbell is now unusable. The design is very nice, and it's very tempting to buy it (which I did, despite the negative reviews), but really don't make the same mistake. Much too fragile.

Beautiful and does she work
Hope find him too quiet but he just has good presence. Feels solid. Sits on me mtb and doesn't really stand out because of ze shape which I like.

Incredibly satisfied with super quality and golden service!
This is certainly not the first time I have given this bike bell as a gift to an avid cyclist. Every time I get asked where I got this beautiful bike bell. And every time I give the same answer: MANTEL!!!

Nice design bicycle bell
Cute bike bell! A different design than the normal bike bells. Nicer, less noticeable on the handlebars. I also like the sound better than the normal bike bells.

Handy little inconspicuous bell
I have 3 of these bells now , 2 on the mtb and 1 on the road bike. They are inexpensive, light and hardly noticeable. I use them regularly and they are loud enough for me. Unfortunately for some people no bell is loud enough so they don't move. A pity is that the spring is not made of stainless steel, so it rusts after a few times cleaning and/or rain. But on average a fine little bell!

This bell cannot be used effectively in traffic, but very few road users can hear the bell.

A nice bell that you do want to have on your bike.
A nice bell that is nicely concealed around your handlebars. I asked through customer service if the bell could be blocked by brake cables on the handlebars. The answer was that it is, but I ordered it anyway. With a Tie-wrap on the brake cables this was fixed and now this bell shows off nicely on my handlebars.

If I had to do it all over again, I wouldn't buy it.
Very disappointed with this product, which seemed fine. Unfortunately, it's not as loud as a basic doorbell.

Nice design but very fragile and soft
This is my second one already. The design is beautiful and fits perfectly so the bell is not clunky in the way on my handlebars. However, it is not very loud. Other cyclists often don't pull over until I'm right behind them and so I regularly get the comment "ring the bell!" hurled at the back of my helmet. Calling often and loudly has caused me to lose the fragile knocker during a ride. But due to Mantel's prompt service, I ordered another Knog anyway.

Too expensive, placement on handlebars unfavorable.
Similar product at AliExpress you pay a fraction of this price. Mounts close to the handlebar stem, this is inconvenient if you want to call then you have to release your hand from the handlebar every time.

To attach must be best handle etc. removed. But that's no problem. Also have a similar bell (noname from China) which is felt somewhat louder and brighter in sound.

Fine bell, small use case.
Sat on my bike quickly and looks very neat. Unfortunately, when calling the plastic button on the spring sometimes shoots crooked. Then I can no longer ring properly. With some fiddling I can get it right again. But it is not ideal. Despite the fiddling, he is not yet broken. Otherwise a fine bell with clear sound.

Not annoyingly visible bike bell, top!
Walkers appreciate a bike bell instead of a "good morning! Not expected, but it does indeed work. And this version is the least annoying on my handlebars. Win win

I highly recommend it to anyone looking for a bell in harmony with their bike.
This doorbell is exactly what I was looking for. It's really complete, even with the installation key. Its design and tone are perfect. Modern, discreet look.
