Reviews over the

Knog Oi

fine bike bell! The slim design leaves enough space to easily rotate my phone on my handlebars' phone holder. The cutouts through which the brake cables are routed are also handy. Especially on a road bike, where these run tightly along the handlebars. The design does make the sound of the bell not very loud, but so far I haven't had any problems with it.

Pros & Cons

Very good but too expensive

very easy to assemble, excellent in use

Pros & Cons

I was looking for a compact bell for my reace bike that is easy to operate while still having full grip on your handlebars. This bell totally meets that requirement.

Pros & Cons

Good price/performance ratio. Fits unobtrusively into the overall picture.

Nice packaging, easy to assemble and beautiful design

Pros & Cons

Installation is easy and good please note correct diameter of your handlebars, bars before ordering

Pros & Cons

Fine bell and looks nice. My brake cables are on the outside of my handlebars, bars, at first the bell hit them and muffled the sound. So mount it so the bell doesn't touch anything.

Pros & Cons

Very irritating that this relatively expensive bell keeps ringing while cycling. On cobbles all the time and further on slight bumps too. One does hear you coming.

Pros & Cons

If you want to keep the sleek line of your bike

Pros & Cons

Product komt overeen met de beschrijving en voelt degelijk aan. Belangrijkste is dat hij niet te luid/hard is en een ontzettend fijn geluid maakt.

Pros & Cons

Easy to assemble

Pros & Cons

Nice and handy bell that doesn't get in the way.

Pros & Cons

What a beautiful bike bell and what a nice sound. Only a slightly longer screw would be desirable for the slightly thicker bike handlebars.

Pros & Cons

Sounds good, looks nice and fast Mounts super-conveniently

Pros & Cons

Have been using it for a week now and am satisfied.

Pros & Cons

The bell not only looks beautiful but is also functional.

Pros & Cons

Fits nicely behind my Deore XT M8100 brake lever, making it easily accessible on the handlebar and barely visible

Pros & Cons

Very nice product. Neatly finished and fine material. Easy to assemble. The bell is clear and gives ample sound. But it is not intrusive, which I personally like in relation to other road users. And furthermore, as always, super fast and good shipping via Mantel. Top

This product meets all my expectations

Not only me but also those around me are happy with this bike bell on my cycling bike

Pros & Cons

Nice minimalist bell. Is nicely one with the handlebars

Pros & Cons

Perfect!

The sound is very nice, but there are bells that sound louder. The bell sits nicely on the handlebars and is easy to operate.

Pros & Cons

Suitable for a racing bike, does not take up much space on the handlebars where it is already tight from the start.

Easy to mount, nicely unobtrusive on t handlebars and still a good volume.

Pros & Cons

Have several on my bikes. Stand out beautifully with minimalist design. Sometimes a bit tricky with handlebar bags with bikepacking. You have to keep the bell clear then.

Pros & Cons

Nice little inconspicuous bell. Has a nice and clear sound If you are looking for a bell, look no further and go for this one

Pros & Cons

Fine stylish bell that stands out minimally on the bike. This allows me to make myself known to walkers on gravel paths, but do so very subtly. I have absolutely no problems with unwanted ringing noise due to bumps or forest paths. This is also clearly explained in the "how to" that you should not tighten the screws super tightly when mounting.

Pros & Cons

Bike bell that does fit snugly around my handlebars

Pros & Cons

Works well

Pros & Cons

Belts good

Pros & Cons

Recommend!

Simple installation

Pros & Cons

Installation takes just a few minutes and is a simple matter of following the recommendations. Your bike will look impeccable with this unobtrusive bell!

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

Pros & Cons

Well audible but not irritating to other traffic. All parts are coated so I expect a somewhat longer lifespan than previous purchases.

Pros & Cons

fine product, nice sound, easy to apply.

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.

Pros & Cons

I already have a Knog and have been using it on my road bike for a few years. The bell is made of durable materials

Pros & Cons

Exactly what you are buying!

Pros & Cons

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.

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 .

Pros & Cons

Top bubble

Pros & Cons

Installation no problem, but later found that I was not heard in some busier city traffic.

Pros & Cons

Product meets my expectations

Pros & Cons

Very nice non-obtrusive clear-sounding bell

Pros & Cons

Nicely finished, fits perfectly next to bike computer and you can access it easily from the grips

Pros & Cons

Bell works fine, you can react quickly and the sound is really audible. A bike bell that doesn't look like a bike bell.

Pros & Cons

I've been very pleased with knog oi bell. It's a game changer on the road, now other users can hear me coming and my bike remains cool and aerodynamic

Pros & Cons

Does what it needs to do

Pros & Cons

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

Pros & Cons

Easy fast small almost invisible,

Pros & Cons

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.

Pros & Cons

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!

Pros & Cons

Pros & Cons

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

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.

Pros & Cons

Delivered well and quickly. Easy to install.

Pros & Cons

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

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.

Pros & Cons

Belts good, not hard

Pros & Cons

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.

Pros & Cons

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.

Pros & Cons

I expected the sound to be a little better but the design is very nice

Pros & Cons

I have tried Knog Oi on several bikes. It is just a good and nicely finished product.

Pros & Cons

Great bell, mounting super easy and just looks really tight on the bike

Pros & Cons

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!

Pros & Cons

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).

Pros & Cons

Als ik twee maal met mijn fietsbel bel nou dan weet je het wel. Het maakt het wielrennen een stukje veiliger.

Pros & Cons

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.

Pros & Cons

Exactly what I am looking for. I am satisfied this bike bell.

Pros & Cons

Nice minimalist design, good quality and plenty loud. I bought 2 immediately 1 for mtb and 1 for gravel bike.

Pros & Cons

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

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.

Pros & Cons

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.

Pros & Cons

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!!!

Pros & Cons

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.

Pros & Cons

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!

Pros & Cons

Installation is easy and sound is fine. However, the volume could be a little higher.

Pros & Cons

bell sits nice and tight on your handlebars, sound is a little too soft

Pros & Cons

It fits perfectly on the handlebars.

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

Pros & Cons

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.

Pros & Cons

Very disappointed with this product, which seemed fine. Unfortunately, it's not as loud as a basic doorbell.

Pros & Cons

Nice design, sometimes when is wet it sounds less noisy

Pros & Cons

Beautiful matte black bell purchased Beautifully designed and ringing is easy Really an ornament on my racing bike

Pros & Cons

Poor sound makes it not recommended, certainly not for the price you pay.

Pros & Cons

The bell works well, is in harmony with the handlebars.

Pros & Cons

Looks sleek, but you don't get much use out of it; produces very little sound.

Pros & Cons

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.

Pros & Cons

This is a slim line bell that does what is needed at a low cost. Perfect for road/Gravel or MTB

Pros & Cons

Works well, could be little louder.

Pros & Cons

Eenvoudig monteerbaar. Mooi design. Wel een vrij hoog geluid waardoor sommige mensen de bel wat later horen. Keertje extra bellen voor de zekerheid

Pros & Cons

Attractive, discreet look. Integrates perfectly with other controls. Sounds loud enough, but not every time. Seems fragile. To be seen over time.

Pros & Cons

Easy to mount does not get in the way and is easy to operate In addition, it looks perfect

Pros & Cons

Easy to mount with all the parts it fits any handlebar great

Pros & Cons

Nice bell that you hardly see. Bell does not go very loud but loud enough

Pros & Cons

Great ringing watch! Design and function in perfect harmony

Pros & Cons

Ideal for the road bike and a must have for every cyclist. Weighs nothing. Well audible for other road users
