Too soft

- Jonathan, 24 May, 2023

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

assembly
looks nice
far too soft
operation poor and not durable

Nice thing but very dependent on your bike whether it works at all

- Youri, 5 February, 2023

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

Beautiful design
Works poorly with non-cable integrated bikes

If I had to do it all over again, I wouldn't buy it.

- Christian, 27 September, 2022

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

Holds on the hanger

Looks nice but sound worthless

- Erik, 24 March, 2022

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

Sound much too weak -> unusable

Beautiful , but durability not yet top (in my model)

- Edwin, 31 October, 2021

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

does not stand out
nice
cable quickly against it
spring gets lame

Nice design but sound too soft

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

Nice bike bell but totally not usable for long time due to bad mechanism of the spring.

- Philip, 1 July, 2021

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

Cool design
Spring breaks quickly. Bell unusable.

Pros & Cons

Easy to assemble
Stylish and unobtrusive

Spring on which the hammer sits is easily damaged

Mostly beautiful. Less functional.

- Jelle-Bart, 18 May, 2021

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

Pros & Cons

Easy to attach
Nice dinggg
Not loud

Good idea, extremely poor execution

- Koen, 12 May, 2021

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

beautiful design
spring

Would definitely not recommend this bell.

- Daan, 10 May, 2021

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

Nice design
Sound is fine
Expensive
Irritating vibrations during cycling
Plastic hammer/spring that breaks quickly

The most beautiful bicycle bell, but mediocre quality

- Jules, 4 May, 2021

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

The most beautiful bell I know
Moderate quality

Vulnerable, quickly broken.

- Nils, 20 April, 2021

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

Pros & Cons

Beautiful design
Unobtrusive
Moderate volume
Quickly broken

Too expensive for minimal sound

- Boris, 21 March, 2021

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.

Age-old problem: button breaks off

- Michel, 22 November, 2020

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!

Small, does not get in the way

Expensive
Vulnerable!

Moderate, spring rusted through after a few months

- Joeri, 27 October, 2020

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....

Far too soft

- Erik, 19 October, 2020

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.

nice bell, moderate quality

- Albert, 19 September, 2020

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

does not stick out on the handlebars
looks nice
bad spring

Leaves quality to be desired

- Arald, 6 July, 2020

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

Easy to mount
Sleek design
Not well audible for fellow cyclists
Spring is of poor quality and gets lame quickly
