I will put another plug for airzounds. It actually makes people laugh. They don't expect it from a bike.

Best bell out there!

3 of my IGH bikes have a Mirrycle Grip bell on the opposite side.

Incredibell Grip Bell ? Mirrycle Corporation

Another vote for Spurcycle bell.
I purchased the clone from Amazon and the actual Spurcycle bell from their website. Equal amount of use, the clone bell just gave up the ghost. The Spurcycle bell is still going strong.

Has it arrived yet?

Of all things, I'm overthinking this. I like the Crane, but for NYC street riding I feel like single-ding bells just don't get enough attention. You've seen and maybe heard the cheapo bell I have on my International, it has the classic r-r-r-ring-r-r-ring sound (no idea how else to describe it) and that seems to get more attention. The one I have has plastic innards so one of these days it's going to give up, but they're cheap - I could buy 3 for the price of a Crane.

The bicycle rickshaw guys use another kind of bell that's reasonably loud with a two-tone ding-dong that's noticeable.

I haven't installed the $3 bell on a bike yet, but I've held it in my hands and rung it, and it seems every bit as good as a Crane. I recommend it highly.

I know what you mean. The brrrring-brrrrring bell is easier to modulate and easier for the pedestrian to understand. But practice with the Crane, as if it's a musical instrument, pays off. Since it's loud and vibrates for a good long time, I can ring it from 30 feet back, and it's still ringing while I'm passing the pedestrian, so it serves the purpose. I wait to see them turn their heads or otherwise acknowledge hearing it. If I see no sign, I assume they'll act erratically, and I pass them very slowly.

Sold out.

It's my fault.

If I have a noisemaker mounted at all, it's an Airzound. Almost all of my riding is on high speed (60 MPH) roads. There's only a small part of my current route where pedestrians are even a possibility, and I've never seen more than 2 or 3 a day. For cars, bells are useless.

Yet another vote for the Spurcycle bell.
It's incredibly well made - in the good ol' US of A!
Sounds great, no false rings going over rough terrain, fits any handle bar diameter, and a super-secure attachment mechanism that stays put.
The all metal (brass and stainless steel) materials used in it's construction show no signs of corrosion after three seasons of sweat and precipitation.
I think it looks great too!

Just a quick sampling of opinions agreeing with mine!
I've used one of these for years, and I have found it very effective in traffic. I don't know about it making people laugh, as suggested ^^, but I think cars definitely do not expect this loud a sound from a bike, so they respond as if they think they've failed to notice another car. Results can be fairly dramatic.
FTR, mine is a "Blast", which I got from BioLogic (BioLogic Blast Airhorn | Premium Bike Gear). I believe it is a re-branded AirZound.

Two recommendations:
1) mount the horn where you can reach it *while* braking, and
2) always leave yourself an "out"... the horn is not an airbag.

The Spurcycle bell looks and sounds awesome. It's kind of expensive.
My wife is getting me on for Father's day.

I had a squeeze horn back in 1981 when I was living in Boston and working in Cambridge, MA. Remember those? Mine had three horns pointing forward, and it made a dissonant chord. Twice it saved my butt, and they were amusing. Once, a car driver tried to right-hook me, and I honked, and he stopped, and I proceeded. When he saw I was "only" on a bike, he honked back. The other time, two pedestrians stepped off the curb against the light. I honked, and in unison, they JUMPED BACKWARDS back onto the curb!

The horn looks silly and childish, but it works. The trouble is, you can't find a well made one any more.

I recommend trying electric bell with built-in headlight. People seem to hear it better if you are behind them
