Reviews over the

Knog Oi

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

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

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

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

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

Pros & Cons

Weak sound, almost inaudible! Pity because beautiful elegant bell

Pros & Cons

Likes poorly, spring is too weak, therefore weak sound to alert

Pros & Cons

Bell is broken within a very short time. The spring turns and then the bell is unusable. Worthless bell in other words.

Pros & Cons

Fragile thing, breaks down very easily. And then also is expensive. Don't.

Pros & Cons

Defective after about 10 calls. Spring bent. Bell unusable

Pros & Cons

the bell becomes unusable after a few runs because the spring is too soft

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 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

Bell was broken immediately, so my experience is negative.

Pros & Cons

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

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

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

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

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

At is already 2 times the spring bent

Pros & Cons

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

worthless just stop selling

in January 2019 bought the bell , after a 3/4 year spring broken / gone , for warranty got a new one, unfortunately now september 12 again the same problem, want to call , but unfortunately the spring jumps away again. with the few times I have to call it is clear to me that I no longer recommend this beautiful bell to buy. a simple free NFTU bell has been doing perfectly for years!

Pros & Cons

Pros & Cons

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

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

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

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

Pros & Cons

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

Pros & Cons

1 year in use and then spring broke off, not repairable!

Pros & Cons

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

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

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

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

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

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

Nice bell, wonderful, also loud enough and convenient. But.... at the first wrong touch (mtb, so that can easily happen) the little hammer breaks off. Not repairable anymore. Gone expensive beautiful bell!

Pros & Cons

Beautiful bell, but about the quality I can be brief. After several months of use, the spring was completely rusted through. Not made to be used outside, where a bike is normally used....

Pros & Cons

Beautiful design but absolutely not practical. The sound is much too soft. Also, the plastic clip used to ring is very weak. Bends in all directions so the bell is not hit properly.

Pros & Cons

Bell looks nice and when it does it gives a good sound. Unfortunately with me the spring broke/stretched after only a few months. This is the weak point of the bell.

Pros & Cons

I am now 2 years along and have had 2 of these bike bells. When I purchased them, my eye fell on the subtle/tight design, but I would not order these again. The first bell was pretty much defective after 2 months in my opinion. The spring was lame/bent which made ringing quite difficult. Also, this bell produces very little sound. Over the past 2 years I have regularly overtaken irritated recreational cyclists on my bike who were still yelling at me to ring the bell. Tip: don't make the same mistake I did by looking only at the appearance of the bell! A Hidemybell combined with a navigation is much better quality and produces more sound.

Pros & Cons

The sound is very weak and it's a pain to put on bars: the screw is far too short. Apart from that, it's a wee elegant bell.

Pros & Cons

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

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

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

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

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.

Pros & Cons

I find the bell too quiet for road traffic

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

Very nice design, quality is disappointing

Pros & Cons

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

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

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

Small and compact bell, only broken too quickly

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

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

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

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 bell and good loud sound, but unfortunately far too fragile. After a few weeks the little hammer broke off and the not exactly cheap bell could be thrown in the trash.

Pros & Cons

Beautiful bell, very nicely done, does not stand out. Nice material. Also rings very loud and fits the thicker rod. Beware of wires though; the bell is in the curve, making it sensitive to wires hitting it. Spring to ring is sensitive though, bends too far quickly. With some harder pushing the bell still works. All in all a good purchase that allows you to let those ahead know you are coming without having to hit the brakes.

Pros & Cons

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

Pros & Cons

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

brilliant minimalist bell that produces a loud piercing sound yet very sleek enough to dovetail an aero bike.

heb deze bel gekozen omdat deze mooi slank is en dus bijna niet opvalt op je fiets. daarnaast ook een duidelijke ping!

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

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

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

Montato su monopattino elettrico si integra benissimo. Nonostante il suono non sia particolarmente forte viene percepito.

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

Works well, could be little louder.

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

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

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

Belts good, not hard

Pros & Cons

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

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

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

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

Pros & Cons

Bought for road bike. Works fine for purpose

Pros & Cons

After reading many reviews I found that it does go pretty hard, so don't hesitate maa buy it.

Pros & Cons

Does the job, discreet on the hanger

Pros & Cons

In stronger winds and more ambient noise, the bike bell is not easily audible to fellow road users

Pros & Cons
