Another quality product from ROCKBROS
It is an another quality product from ROCKBROS. The bell is nice and it keeps hidden as mentioned in the title. The bell is not loud compared to conventional bells but the sound can heard from far distance due to high pitched. Also, it is easy to install and it is perfectly fits with my handlebar. Also, it keeps your handlebar neat & clean. Coming to the finale, I must say it is a good and high quality but it is overpriced as per product. I may recommend this for buying.

Loud & clear
High pitched sound, travels more distance to alert pedestrians & other vehicles from far. Time will tell how sturdy is the buckle to hold it on handlebar & also the spring attached with the hammer.

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 on 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.

Works really well. Very loud. Have replaced other brand which originally come out with this design. This is an improved version. Have bought 2 and will get a few more for my other bicycles.
