ROCKBROS Bike Bells Hidden MTB Bells Bicycle Bells for 22.2mm Handlebars, More Than 100dB, Clear & Long Sound Ringer, Mountain Bike, Scooter, Youth Bike

The ROCKBROS bell is easy to install, small and discreet, taking up little space. The sound is loud and clear, made of high-quality and durable materials. A great solution, not bulky, and looks nice

The sound of fat tires on pavement is not enough noise to be a sufficient warning that someone is quickly approaching from behind, at least not at my local park (in small town less than 4k people). Our park isnt too noisy, but sometimes log trucks rumbling past the nearby highway can be loud. I mainly have to deal with people staring at their phones, and a few who are lacking in riding path etiquette. I like this bell because it is discreet (smallish and black so it blends in with my handlebar) and the ring is clear, crisp and resonates a decent amount to politely but adequately grab peoples attention when they are hyper focused trying to catch Pokémon or doing whatever o their phone.Riding over semi rough terrain and wearing thick gloves during inclement weather necessitated me to tighten it once or twice as it took a little extra effort to flick the ringer. I dont feel like re-tightening will be an issue if you arent wearing thick winter gloves or riding mainly on pavement.~ Be careful not to over-tighten or it may drastically impede the ringing function. You will know it’s too tight because the resonating factor totally disappears and all you get is a dull clunking ping noise. Over tightening caused the springs on mine to come out of alignment but this was easily fixed by removing the bell and wiggling the joints where the springs are housed, and a little poking with a random tool until they straightened out/popped back into place fixed it good as new.I have been using mine during dry and rainy days, it still works great and has no signs of wear or tear.If anything changes I’ll update my review but for now I would highly recommend this bell as an added safety feature to a bicycle or scooter. Since I do not live in a highly populated area I cannot comment on how effective it is in noisier conditions.

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.

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.

I really like how small and hidden this bell is. It has a great sound too. It's much louder and carries/resonates much better than standard bells.

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.
