The ROCKBROS Hidden MTB Bike Bell has a sleek, minimalist design that blends perfectly with the handlebar, making it a great option for those who prefer a low-profile look. The bell produces a clear and crisp sound, and the 100dB rating is decent for most casual rides.However, I expected the bell to be louder. While it works fine on quieter paths, it struggles to cut through traffic noise or crowded urban areas. The sound could definitely use a boost to ensure it’s heard in all conditions. Additionally, the ringer mechanism can be a bit stiff, which makes it slightly difficult to activate, especially when wearing gloves.Overall, it’s a stylish and functional bell, but it falls short in terms of volume and ease of use. If you’re riding in quieter areas, it’s a solid option, but for busy city streets, you might want something louder.

This is a great little bell with a low profile design. It has a nice, loud and crisp ringing sound. The bell fits securely on my bicycle handlebars without feeling bulky or obtrusive. The form factor is really nice - it's compact and doesn't look out of place on my bike. Overall, I'm very pleased with this bell and would recommend it.

These are tiny but pack a loud sound. We have limited space on our handlebars and these are perfect. They seem to be made of a durable aluminum with a rubber “nub” to flick the bell. Once mounted they are tight and don’t move. A great price for a must have item.

I picked this up to add to my commuter bike, and I was impressed by how loud the bell actually is. It's easy to use, all you do is flick the hammer back, and it rings loud enough that anyone will hear you coming. It feels like a sturdy product--it fits snugly on your bars, and seems like it could take a hit.Unfortunately I can no longer use the bell, as it's too small for my new drop bars, but I would definitely buy another if they made a larger size.

The ROCKBROS bell is outstanding! It installs easily and its stealthy look disguises that it's a bell. I don't know why some reviewers claim it's not loud because it's louder than any bell I've ever owned that came from Specialized or Trek. Just give the little spring-mounted button a pull and release and the bell rings out crisply and keeps ringing for a time. Like any bell, your hand will mute the ring if you touch it while it's ringing, but if you keep your hands away it rings perfectly. I'm very pleased with this bell and will transfer it to any new bikes I get.UPDATE: I sold my Specialized bike and forgot to remove the bell before the buyer came to pick it up. He asked, "What's this?" pointing to the bell. I told him what it was and said I'd remove it (kicking myself for not doing so earlier) but after he heard the bell he said to leave it installed. Goodbye, ROCKBROS bell. I just bought another one to go on my new Trek Rail. These are outstanding bells. Just remember to remove yours when selling your bike so you'll have it for your next bike . . .

I live in the mountains where mtb trails (unfortunately) aren't directional, which has lead to some pretty bloody bike crashes. Having some type of bell is really kind of critical in my area. I've got 3 mountain bikes and 2 road bikes. These bells won't fit on my road bikes (due to the design of my carbon bars) so I have no experience with them for road use. I've got them on a couple of my mountain bikes and do use them frequently. I don't think these things really look great, but they work pretty well. People can hear me from around 1/10th of a mile away and unlike some other (cheap) bells I've used, these have held up to some pretty rugged rides. I've only got one real downside to these and it might be a deal-breaker for some mountain bikers. I've got a Timber (branded) bell on my full-suspension mtb, and that bell can be switched to just rattle & make sound constantly (i.e. every bump you hit will rattle the bell to basically make constant noise, especially on a downhill). When I'm flying downhill (even on an XC ride) I'll let the Timber just rattle constantly--you'd have to be deaf to not hear that thing. Everybody on the trail is going to know you're barrelling towards them with that bell. The Rockbros. bell requires you to actually flick the spring to get it to sound. And you won't be able to constantly flick it if you're barrelling downhill. You MIGHT hit it a few times at strategic points, but it's designed more to alert people you can SEE. It isn't the type of bell you can basically unlock in order to create constant noise. But what I'm describing is a fairly niche use scenario. Ultimately, these are pretty decent little bike bells that make enough noise when you flick the spring and that is really all most people require. If you're an urban cyclist or a parent considering buying these for a kids bike--I think these are great. They've held up far better than cheap bike bells I've purchased previously.
