ICE motorbikes seem like the most obvious type of vehicle to immediately mandate 100% EV, with an aggressive target like 12 months (to clear out existing inventory). The segment and vehicles themselves are small enough that this changeover can be made fairly easily, with immense benefits for noise pollution in cities.

I suspect that the noise is a big appeal to motorcycle owners.

Is there an industry name for this specific phenomenon? Where goods are purchased/owned/carried solely for an intimidating appearance without any intent of using for their intended purpose?

I live about 5 miles (on the same road) as the local Harley Davidson dealership and would love it if HD riders left the stock pipes on their bikes. While the engines do vibrate, don't dismiss the additional concussive force of an unmuffled exhaust.

Isn't there a legal limit on the amount of dB(A) produced by any vehicle?

I would love to see statistics on how many tickets are issued per year for these violations. I suspect zero.

(Sweden situation). There's recurring inspections of any vehicle, binannually or something maybe for motorcycles. The HD people I know/knew, would change back to the stock pipes for inspection, because the loud ones were not legal to use. Then just change back again.

Or they just add/remove the DB killer (removing a small plug vs dismantling the exhaust)

With Euro4 and later exhausts this is no longer possible. Db killers need to be not removable, so you need to replace the whole slip-on.

For the bikes being loud enough that everyone knows you’re coming is life and death issue on the road surrounded by huge cars and trucks

Sorry, but as a person with over 15 years of motorcycle driving experience - "loud pipes save lives" is mostly a myth. They may help sometimes, but they can also be dangerous since in some settings they can scare the heck out of the car driver which can lead to them making unpredictable choices.

Ultimately, the best thing a rider can do is take total ownership over our safety - full protective gear, constantly taking advanced riding training courses, and above all - always riding at a reasonable speed for the road, visibility and traffic conditions.

That’s the sales pitch, but I haven’t seen any evidence. Almost all the sound is projected behind you, where people can already see you (and where high-vis clothing would be more effective than sound anyway, but you don’t see many bikers wearing that). Anecdotally, the people I’ve known with loud exhaust systems are not what you’d call “safety conscious”.

Even if it's ineffective, it's still a psychological safety blanket. It's much the same reason that bikers ride in groups.

This doesn’t deserve to be downvoted. The statement is correct. I have a permanently destroyed right foot and ankle because someone made a left turn from the right lane just outside the Holland Tunnel in NJ back in 2004. The driver “didn’t see me” before making the illegal turn and planting his Mercedes horizontally across my lane as he slowed to enter the gas station driveway. I laid my quiet 800cc bike down and plowed into his car at 40mph, crushing my right leg between the bike and his driver side door. I now have 4 toes, limited mobility, and near constant pain with every step I take. After that I put straight pipes on my bike and had countless other situations where a car would start to change lanes into me and then move back when I gunned the engine to let them know I was there. Loud pipes save lives. Car drivers are often oblivious of their surroundings or distracted by their phones or music. When they check their blind spot the brain is looking for car or truck shapes and ignores motorcycle shapes as it quickly assesses the clearance of the lane. I’ve had people look right at me and then change lanes into me. I’ve kicked cars and cabs from my motorcycle as they are pushing me off the road. 100% of accidents where a car hit a bike use the excuse of not seeing the motorcyclist. I’ll make sure they can hear me too.

You are clearly not a biker... otherwise you might have understood why EV motorcycles are years, maybe decades into the future.

If you refer to e.g Asia where motorcycles are possibly your only transport, then sure; your argument is valid. But this is HN, and in Western countries a motorcycle is basically a hobby. Heck, they are often even more expensive to run than cars.

So as to why EV bikes are not even close to being ready:

(a) The range is abysmal, and the availability of charging simply isn't there in areas that many bikers venture (away from traffic, hundreds of miles into the hills). Motorcyclists try to avoid the interstate and main highways if possible. You rarely see a Zero bike for this and many other reasons. A proper ride may be 12 hours per day for hundreds of miles, for days on end.

(b) Battery mass. The energy per mass unit in even the best batteries make it very impractical with motorcycles that really need to be as light as possible.

(c) Longevity. A lot of bikers own not just one, but many motorcycles. You may have the latest BMW R1250GS, but also a garage littered with anything from KDX 200 to DRZ 400 and Honda CBR1000RR. Those bikes can still be used for years to come, and it doesn't make sense to scrap them. PS - bikes are generally not that reliable though, but that doesn't necessarily affect longevity too much as owners love to tinker.

It isn't just iPhone, and it can happen on any motorcycle regardless of the engine size or power. The OIS in my Pixel 4a is destroyed from using a mount for less than an hour.

Just to be clear, this isn't about using the camera while mounted on the bike, but having the phone mounted ever actually damages the camera for any use, mounted or otherwise?

TLDR shaking the phone anywhere at any time with certain amplitude / frequency combinations will permanently damage sensitive components and make pics look like you’ve got ALS again

Yeah they actually go into more interesting detail than expected from a support article and detail how (not an expert so it could just be wool over my eyes Apple BS but doesn’t smell that way here) the OIS and closed loop AF work in that article.

Basically sensitive gadgets shouldn’t be exposed to certain frequency / amplitude combinations because sensitive gadgets rely on well, not being shaken out of whack.

That is one way to kill an entire industry. Electric motorcycles have been here for years, nobody is adopting them because nobody wants them. They are closer to electric bicycles than they are motorbikes. When I jump on my motorcycle, it is about the experience - not anything practical. The startup ritual, the heat of the engine on a cool day, the symphony of sound and vibrations, the weight of what is under you, the…

I wouldn't mind the industry being killed. But then again, I'm only on the receiving end of the noise, stink, bad drivers, people using infrastructure for pleasure etc. I bet if I liked driving for fun or using shared infrastructure for pleasure instead of need, I might like it too. But I don't.
