Reviews over the

Knog Oi

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

Pros & Cons

eerste dat opviel is het duidelijk lagere geluidsniveau binnen enkele weken vervormde het veertje waardoor de bel helemaal niet meer functioneerde

Pros & Cons

After much deliberation, I bought this bell. After all, I was looking for a bell that wouldn't stand out so much on my nice road bike handlebars, but the lesser reviews initially held me back. I ordered it anyway, and so far I am impressed! The sound is not méga loud, but the nice sleek design makes up for it. Hopefully it will last a long time!

Pros & Cons

Looks nice but sound is way too weak. So it is of no use. I bought a normal bell again.

Pros & Cons

A little disappointed by the low volume of this horn, when others of similar design offer a much more audible sound to other road users.

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

Very nice design, quality is disappointing

Pros & Cons

Chose these because of the sleek looks on my bike handlebars. Had some doubts at first about the audibility of the bell but so far it's going fine when overtaking

Pros & Cons

Fine bubble. Now to wait and see how well the plastic holds up

Pros & Cons

I am satisfied, original product, light, easy to assemble.

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

Should sound a little louder but satisfies fine and is discreetly built around handlebars. Mounting with 1 screw.

Pros & Cons

Slightly faint ringing in the middle of traffic

Pros & Cons

Thanks to its thoughtful design (cutout for cables), it mounts nicely on the handlebar, close to stem so it is almost unnoticeable! (in black version)

Pros & Cons

Works less and less well each time until the spring is stretched to the point where no good force can be applied.

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

It has lasted me a day. I rang it 5 times in a row to warn some sheep I had on the road, and the spring has bent away from the bell, so now it is almost impossible to ring it. Maybe I'll leave it on just in case the Guardia Civil stops me and asks me if I have a bell.... It's not going to be useful for anything else.

Pros & Cons

After a few calls spring bent, looks slick but does not do what it was hired for.

Pros & Cons

The bell was broken within a week. The spring skews very quickly. I put it back a few times but it broke off after six months. Also from a buddy it was broken very quickly.

Pros & Cons

Good design. Not loud enough and even less so by rain. Still very fragile construction. Knog warranty does not achieve anything.

Pros & Cons

A nice bike bell because it is so unobtrusive. The volume is not very loud though but it does go.

Pros & Cons

Hele mooie en goed werkende bel alleen jammer dat het veertje dat de hendel vast houdt niet roestvrij is en ook moeilijk droog te houden.

Pros & Cons

It looks great, I really like the look. But it's typically the case that the design is over the function.

Pros & Cons

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

Pros & Cons

nice thing, but a few practical objections. 1. when installing be careful that your cables are not against it, otherwise you will have no sound. 2. After 1.5 the spring mechanism is gone. almost unusable.

Pros & Cons

Almost perfect, for best noise the "operating" needs to be precise

Pros & Cons

Bell was broken immediately, so my experience is negative.

Pros & Cons

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

Pros & Cons

Unfortunately, this bell was hugely disappointing. Not loud enough, especially in wet conditions. Also broke within a few months.

Pros & Cons

good and aesthetic product with first class sound

Pros & Cons

Don't buy if you're looking for a ringer that should only give a loud ring tone when you call

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

For now it does ok, but it really is a fragile thing. This is also evident from the other reviews, which I really should have read earlier.

Pros & Cons

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

Pros & Cons

I like that this bell is so narrow. It fits just between the stem and the tt bar. And has a nice clear sound.

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

Purchased this product a few months back. After a few rides the spring broke and this is not repairable. Worthless

Pros & Cons

Good and loud bell! The sound is not too sharp

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

Too bad the button to call with has a weak spring. After 1 ride already bent. Will still work (but no longer by pushing down). Now have to push the button forward against the bell myself to ring.

Pros & Cons

If only I had read the reviews earlier: indeed too soft sound and not durable. Biked with it 4 times and the spring is already "stretched" because you have to push the hammer too far away to get an audible "pinggg". In short: leave this product on the shelf and just go for a BBB Loud&Clear or Noisy Brass. Maybe a little less pretty, but they do work.

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

Small and compact bell, only broken too quickly

Pros & Cons

Bad mechanism Was able to use the bell a couple of times after which the spring turned and just stopped ringing. Worthless purchase.

Pros & Cons

People do not hear the bell at a distance, only when you are close (but that is too late)

Pros & Cons

You can put this bell to good use for a year. After the spring has stretched a bit. Is the bell unusable. Spring is also subject to corrosion so the bell just breaks down over time.

Pros & Cons

nice design, could be built even smaller

Pros & Cons

Have had the bell on the bike for 3 years now and just going to try the more deluxe version to see if it's better liked

Pros & Cons

Great expectations given the price but a very fragile product that you notice when assembling. Valve after a while will clamp, feather rusts and therefore lacks function because you can not call hard enough. Not recommended.

Pros & Cons

After 3 weeks of use very satisfied with it.

Pros & Cons

It seems that this bell has received an upgrade. Where previous models had a weak spring, the current spring seems to be a lot firmer. The result is a nice looking bell that is barely visible on my road bike AND the confidence that it will last a lot longer these days.

Pros & Cons

Gekocht op uiterlijk en merk. Is echter goedkoop product, kermiskwaliteit. Was na een paar keer bellen al kapot. Kies wat anders!

Pros & Cons

I expected the lever to be sturdier for a bell of this price.

Pros & Cons

It is mostly a nice bell. Not very loud. Only catches the eye after ringing at least 3x.

Pros & Cons

Nice bike bell that is almost "invisible" on a road bike. However, the spring is problematic, as previously posted in reviews. It gets so warped that the bell simply no longer works. Silly design flaw, because otherwise it would be a topper.

Pros & Cons

Unfortunately after 2 uses spring bent. Design is beautiful but unfortunately the quality of the product is poor. For this price you should expect more and at least no plastic and a better mechanism (spring).

Pros & Cons

I enjoyed riding with this bell for a year, because very nice (in black on my black bike). But the spring of the trigger quickly started to rust (while bike is indoors) and eventually it fell off on the way so the bell no longer works :-(

Pros & Cons

After one time stored in the shed against other bikes and the "flap" partially broken off and spring bent. Fragile product.

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

Functional design and good operation makes a fine product.

Pros & Cons

If you want a minimalist design on, say, a sleek urban e-bike, this is a very nice solution. Because it is so small, the sound is not very loud, but is noticeable enough due to the high frequency.

Pros & Cons

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

Pros & Cons

The bell sounds too soft, so people don't hear it

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

I'm looking for an especially loud(!) and easy to handle (preferably I don't need to take my hamd off the handlebars) road bike bell. This is my third bell and the sound of the bell fades immediately in the outdoors. The only positive is the design but the functionality of the bell lapses as the sound is far from adequate.

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

Nice bell, loud enough and easy to operate. Easy to mount, with ideal cable cutouts. In just the right spot for my Cube. The control pawl is delicate. It is mainly attached to the spring. Tap it too hard and it is broken. Operate it too clumsily and you can no longer ring as loudly as intended. After a month my bell was broken.

Pros & Cons

At is already 2 times the spring bent

Pros & Cons

Beautiful product. Box includes the tools for assembly. Tight design. Good sound

Pros & Cons

wonderful beautiful bell, topper

Pros & Cons

Pros & Cons

Well-designed bell that also fits around thick road bike handlebars. Nice design. Pretty expensive for a bell though.

Pros & Cons

Aerodynamic bike bell for a good price, nice investment!

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

Sound could have been a little louder.

Pros & Cons

Beautiful (stylish) and fine bell (clear sound) and nice that the brake/shift cables can be hidden under the bell (recess), especially with wide handlebars.

Pros & Cons

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

Pros & Cons

Have had the bell for about 2 weeks now, on a mountain bike ride some mud got between it and then it didn't ring so well anymore. cleaned it again afterwards with compressor and now everything is okay again. that's why I would advise to only use it on a road bike

Should have purchased much earlier - perfect.

Pros & Cons

Very nice thing, but the sound is actually not loud enough. Wonder how long the feather of the clapper will last...is a bit far out.

Pros & Cons

Nice design but the control mechanism is plastic. Especially when it is cold it breaks off. For this money you may expect that a manufacturer has done some endurance testing.

Pros & Cons

This bell is beautiful and does not stand out on your handlebars. With me it broke twice: the spring that holds the bell is very fragile. Also, the large variant is not that loud, the smaller variant seems louder.

Pros & Cons

Bought this bell for 5 persons of the cycling club. Meanwhile already with 4 people no longer workable / audible because the spring is not robust enough.

Pros & Cons

Best bike bell I have ever purchased.

Pros & Cons

worthless just stop selling

Slim bike bell for the road bike that is indispensable these days.

Pros & Cons

Very good and stylish bell.

Pros & Cons

Easy call.
