The Incredibell is a cool little bell. Wonderfully simple design. I had one for about 10 years and the dinger finally broke off-sadness. It has a ring that is loud enough but not threatening to other trail users. In fact, you can make it louder or subtler depending how much you load up on the dinger before releasing it. It's rotatable to make it less obtrusive on the bar (I turned mine forward to hide it by the brake lever) and the dinger rotates too for right or left usage and varying thumbs.
It is a bell, and it rings nicely, but the attachment clamp is not nearly wide enough to fit a standard 31.8mm diameter handlebar, even with the included spacer removed. I'm not sure what handlebar this would fit, maybe one on department store children's bike, but it's definitely not sized for adults.
I've tried the more expensive (and prettier) Crane bell, but found it was too loud. This one is quieter, and for half the price a much better deal. Nice, crisp sound lets joggers know you are coming.
Bells have gotten ridiculously expensive. I like this one for crowded trails because it's relatively cheap and simple. It dings. That's all it does. It's easy to mount and has a cool feature that allows rotation of the dinger to wherever you want it. Nice.
Loud but not satisfying. To ring, press spring-loaded lever down, let thumb slip off lever and plastic lever-hammer springs back up to give a single loud ding - not very bicycle-like. While a standard bicycle (brring!-brring!) bell might also scare people, they instantly know what to look for. Otherwise works, looks nice, seems solid and is compact.
Used on commute to work and on multi-modal paths on the weekend. Does not scare the pants off of others if given enough distance to alert.
Good adjustment for mounting on handlebars also.
Great bell. Easy to mount. Gets people's attention very well. I ride I New York city where bells and lights front and back are the law (you can get a nasty ticket!). It also takes up little room on the bars and I have it tilted forward so it looks a little less dorky. Got it for my sons who are in their early 20s and they actually think its cool to have this bell.
Got this bell to alert pedestrians and other cyclists if I was coming up behind them as I'm not the loudest yeller. The bell is easy to mount, lightweight, and I like that you can adjust the position of the clapper. The bell just doesn't make the clearest ring, and it isn't that loud. If it is wet, it makes more of a thunk than a ring. If I had it to do over, I would probably get the larger version in hopes it would be louder.
