Your bike already has two crappy 80psi pressure vessels, why not three?

Those two pressure vessels are highly engineered and are wrapped with materials with pretty good tensile strength. Also, they’re made out of materials (fabric and rubber) that absorb a decent amount of energy when they tear and that don’t fragment. And the whole assembly usually depressurizes slowly. Having personally blown up beverage bottles by overpressurizing them (be very very careful doing this!), when they go,…

I've blown up beverage bottles for fun. Hooking an air compressor to a 2L bottle and exploding it makes a satisfyingly loud boom.

*We had a valve on the air line so we could be at a safe distance when pressurizing. Be very careful. It's unpredictable exactly at which point they'll blow. Sometimes they hold full pressure for a couple seconds and then go.*

Video version which has more detail than the text: https://youtu.be/zDaVPfpQvPI?is=sSyjXf07r9cg9r4Y Bit cringe marketing though.

I find the "Heard five seconds earlier, the difference between a serious collision and stepping aside" take hilarious. As if there is no other way to prevent a collision in five seconds other than the pedestrian getting out of the way. As much as I get the urge to plow through pedestrians on bike paths (and stay proudly in the way of bikes on pedestrian paths), in real life, normal people don't do that kind of thing.…

Yeah, this while video I honestly couldn’t stop chuckling because it’s built on assumption that bicycles somehow either can’t brake at all or will take five business days to brake like a freight train. Though looking at Berlin cyclists the assumption seems to be true - so many of them insist on just plowing headfirst into an obstacle instead of braking that I start to think that the video was made by one of such cyclists.

Should people with hearing impairment also avoid walking around?

Nope. They get special treatment; and that's fine.

I don't see how they can get "special treatment", the difference between someone who couldn't hear the bell because they cannot and someone who just wasn't paying enough attention to react in time isn't obvious without questioning them. Cyclists should simply learn to share shared infrastructure and be careful when passing people instead, because they can't know if that person is aware of them in time and going to react in a predictable way.

for your safety, when people hear a car horn, they’re going to be looking for a car.

It should make a ring-ring sound but at 120 decibels?

A motorcycle horn might be a better choice

Sure is helpful, because it goes like this: pedestrians first -> then cyclists -> then motorists. You may notice that in this worldview (one which I find very hard to argue against) cyclists should give priority to pedestrians, no questions asked. I don't care about fancy bells or whatever, no-one takes those into consideration even when we (us, pedestrians, that is) can hear them because, and I repeat, cyclists are…

You may not care about fancy bells but you will care about loud honking close to your ears in my very recent experience from the streets of Shanghai. You don't have absolute priority just because you are a pedestrian. > Why can't the cyclists slow down when they see that there's a human obstacle in front of them? Because if the space is limited and they actually want to get somewhere, they just don't have time for th…

> and I give priority to pedestrians when I'm riding my bike

Even when you "actually want to get somewhere"?

Coincidentally, I bought a 12v car horn yesterday with the intent of wiring it into my ebike's power supply with a little button on my handlebars. Not because of other cyclists or pedestrians wearing (anc) headphones but because modern cars are so heavily sound-proofed they don't hear a bicycle bell anymore. A recent incident with an inattentive taxi driver in a brand new EV nearly flattening me prompted me to want t…

If diy doesn’t work I’ve been using loud bicycle horn and it works great. https://loudbicycle.com/

I’ve got one of these fwiw, and it’s outstanding.

This seems to be part of a type of brand marketing where a brand claims it has invented something, but the only thing that ever exists of significant economic value is the attention raised by the promo video / article. Not the thing/service. Examples: - Samsung safety truck https://www.youtube.com/watch?v=6GNGfse9ZK8 - Citroën motion sickness glasses https://www.youtube.com/watch?v=Aco63dlq_WE - Amazon Prime Air http…

To be fair, I think Prime Air is real, but I've only heard about it when they've had drone crashes: https://www.youtube.com/watch?v=NGdOpR-Mv-E

AFAIK it's only available in a few very specific places (seemingly for good reason).

I still think that ringing bells at people is a little rude, regardless of the tone. Like imagine if you were at the grocery store, blocking the isle and someone lightly chimed a bell at you instead of just saying "excuse me". IMO if I'm in a dense pedestrian zone and I can't go around people and I can't communicate by voice, it means I'm going too fast.

Pedestrians still exist in non dense zones. It seems there's no way to win. I've been told that I should use a bell because vocal addresses are too startling. Now if there's not enough room to pass safely and silently I completely slow to the pedestrians speed and THEN calmly say excuse me. But I'm convinced that there is just no universally correct way to do it. If you pass people in any way whatsoever, sooner or la…

Anyone who is mad that you politely passed them at a safe speed is just too sensitive about these things. You're totally fine there. But "room to pass safely and silently" could still piss people off depending on your speed and distance.

Be careful with your ears! (And those of others)

A unexpected loud noise recently caused me to get tinnitus and hyperacusis, and trust me, you don't want either of them!

You know a diagnose is bad when Wikipedia lists suicidal thoughts as a common side effect....
