Knog Oi

Bike bell that does fit snugly around my handlebars

Pros & Cons

Works well

Pros & Cons

Recommend!

Simple installation

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

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.

Very nice non-obtrusive clear-sounding bell

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

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

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

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 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

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

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

It fits perfectly on the handlebars.

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

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

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

Pros & Cons

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

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

Pros & Cons

It doesn't look like a bell, it fits perfectly into the handlebars of a road bike, but sounds like the real thing.

Pros & Cons

I'm very happy with my knog Oi horn, which looks great on my handlebars, and its powerful sound makes all the hikers on the forest paths turn around.

Pros & Cons

A sound system with a great sound, which is discreetly mounted on the black handlebars, and makes it easy to be heard in the distance.

Pros & Cons

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

Pros & Cons

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.

Pros & Cons

Very useful

Pros & Cons

Good to hear and nice and unobtrusive on the handlebars (the eye wants something too

Pros & Cons

Handy little thing , loud enough and nice modest size. I have 3 in total and all work as they should.

Pros & Cons

Just do it, functional and nice and tight on the handlebars. Had read the reviews on the internet, soft sound, breaks down quickly. If you use it normally there is nothing wrong. Subtle bell sound, but then enough. someone with earbuds on won't hear it, even if you yell at such a person. i have an all black bike, but that copper looks classy.

Pros & Cons

Great bell, little bulky really nice and integrates well in the bdc and gravel

Pros & Cons

Matte black is hardly noticeable that it is mounted on the handlebars.

Pros & Cons

It is the best I know to warn passers-by without breaking the aesthetics of the bike and without standing out too much. Indispensable in our days where it is very easy to find pedestrians in the bike lanes or on the paths and roads.

Pros & Cons

Very neat and unobtrusive bell compared to standard bells. Sound is definitely loud enough without scaring people.

Pros & Cons

Bell does not stand out because it is so small but is easily audible

Pros & Cons

good and aesthetic product with first class sound

Pros & Cons

Very easy to assemble and for the price it was really a valuable purchase. Will buy more of it.

Pros & Cons

Super nice bell that also does what it is supposed to do ;)

Pros & Cons

Meets above expectations!!! Super product

Pros & Cons

On gravel as well as canal banks

Pros & Cons

Was very easy to assemble and at least now I am heard.

Pros & Cons

Works perfectly and the sound is excellent

Pros & Cons

This is an unmissable product on your bike. Riding without a bell is anti-social and this bike bell certainly does not mar your bike. Reasonably priced, but good quality product. Bought both for myself and my friend's bike.

Pros & Cons

The bell fits very well into the bike and thus does not disturb the overall appearance.

Pros & Cons

In the store, I asked the salesman, "I don't want a bell, can you help me with that?" He understood exactly what I meant! This bike bell works perfectly and you actually don't even notice you have a bell on your bike! (Salesman also just pointed out to me that there are two different sizes, so just pay attention to which size you need!) Also while MTBing no 'rattling' and functional when needed! Also on behalf of my fellow road users thank you for this advice and this 'I don't want a bike bell' bike bell!!! ;-)

Pros & Cons

Beautiful design. Easy to install, it comes with an adapter for different handlebar sizes. Simple to use, with pleasant continuous sound.

Pros & Cons

If you buy a bell for just its function, there are cheaper alternatives. But the eye wants something and especially on your MTB this bell also makes for a more pleasant landing on your handlebars when falling. It comes in a nice package and the sound is fine!

Pros & Cons

After 3 weeks of use very satisfied with it.

Pros & Cons

Does exactly what it is supposed to do

Pros & Cons

The trails are pretty crowded these days, that you can't go without a bell, and this one doesn't stand out. Top bell

Pros & Cons

The best bell I have had as well. It fits well on the road bike and makes a loud sound.

Pros & Cons

Nice bell and super alternative to hide-my-bell. Fits great on wide aero handlebars(deda superzero). Found the hide-my-bell rather plastic-like and read that it breaks quickly.

Pros & Cons

Sound better than expected and road bike worthy appearance.

Pros & Cons

The clear tone is easy to hear. The bell itself is almost unnoticeable when it is on the handlebars. Because of the different colors, there is a suitable bell for everyone.

Pros & Cons

small in size big in quality

Pros & Cons

Good not too loud bell

Pros & Cons

Beautifully designed bell that does not stand out because of its design and gives a sound that does not startle your predecessors.

Pros & Cons

wonderful beautiful bell, topper

Pros & Cons

Super fijne bel die een goed volume produceert. Mooi design en handig dat je eventuele kabels onder de bel kan wegwerken.

Pros & Cons

A beautiful disign and very good working luxury bike bell. But with a price tag.

Pros & Cons

Should have purchased much earlier - perfect.

Pros & Cons

Best bike bell I have ever purchased.

Very good and stylish bell.

Pros & Cons

Pros & Cons

Pros & Cons

Very subtle bell but with a very good sound.

Pros & Cons

Top marks!

My 2nd of this type. A Knog bell for each of my bikes. Discreet on the handlebars, sufficiently audible. Just be careful not to force the parts too much, and it's reliable. A very good product.

Stylish bell that doesn't look like a bell. So it does not stand out on your handlebars at all but makes plenty of audible sound. It also has cutouts to place over the brake and shifting cable. Just a bit more expensive than most "regular" bells.

Pros & Cons

A nice bike bell that fits on your road bike. Nice model and easy to mount.

Nice design and the ringtone is loud and clear. There is room for cables, however, it sometimes slides off my handlebars so it is not nice and tight.

Pros & Cons

Pros & Cons

Nicely subtle for on the mountain bike. The sound is easy to hear.

Pros & Cons

What a fine bell, very unobtrusive to mount and a very clear ping. Literally a nice piece of safety for the street

Pros & Cons

Pros & Cons

Good sound and nice little bell on your handlebars. Because I chose a black one, you can hardly see the bell.

Pros & Cons

Ideal bell for cyclists placed next to the mio 210 handlebar mount now seems to be one unit. Totally awesome

Pros & Cons

Great product right next to the support of navigation now seems one whole recommended for every cyclist
