> Attaching your iPhone to vehicles with small-volume or electric engines, such as mopeds and scooters, may lead to comparatively lower-amplitude vibrations. No superbikes for you Apple users :D - recoils in anticipation of onslaught of downvotes - In all fairness I expect it's going to be difficult to design anything with such small delicate moving parts to be invulnerable to arbitrary frequency vibrations. It can a…

I think the problematic engines are big Harley twins which vibrate like hell and run relatively low revs. Superbikes engines are usually operate on high RPMs and vibrate less.

Nope, happens with pretty much every bike. Have heard all sorts of riders talk about this.

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.

You aren't a biker and it shows.

Yeah it’s just being a nuisance for the sake of it. There was one who lived over the road from me a few years back who would rev his broken exhaust bike at 5am and wake everyone up. About three weeks later his motorcycle mysteriously caught fire in the early evening. There were people smirking out of their windows enjoying the schadenfreude. There’s still a puddle of aluminium melted into the ground where it died.

> Yeah it’s just being a nuisance for the sake of it. It's a lot like rolling coal[1]. No actual safety purpose, people do it simply to project insecurity and irritate others. Sometimes I think society is too tolerant of purely antisocial behavior, but I guess in the US everyone has the freedom to be a donkey. 1: https://en.wikipedia.org/wiki/Rolling_coal

Oh joy that’s terrible. Had no idea anyone did that.

I'm not commenting either way on the value of loud motorcycles here, but is this related to the article? It says the danger comes from mounting the phone directly to the bike. As far as I can tell, it doesn't say that the acoustic vibrations damage the phone. Would the muffled exhaust also reduce the physical vibrations of the frame?

Judging by the vibrations of my walls: yes. The sooner a maximum noise emitted law for vehicles goes into practice the better. I have a neihgbor here who goes out for small trips 20+ times per day on his HD. Open the garage door, take the bike out (running, of course), close the garage door, rev it a couple of times, wait for a few minutes for the engine to warm up, roar away at maximum volume. Return 10 minutes late…

How are you going to deal with the situation?

You have it backwards. Motorcycle riders are not going to swing over to electric at any time soon: Bikers keep their rides for decades and ICE motorcycles can last just as long and cars, if not longer, and The price for entry on a new electric motorcycle is so far away from the price of ICE motorcycles it financially can not work for owners. And There is little benefit to the environment to switch. Modern motorcycles…

> There is little benefit to the environment to switch. Modern motorcycles have been sold with catalytic converters for decades, and they also get 40+ MPG.

Previous emissions standards for motorcycles were much lower than cars. To the point where a bike getting 50mpg and carrying one person output more pollution than a sedan getting 25mpg and carrying an entire family.

This has been fixed with Euro4's introduction for the 2017 model year (which is why so many bikes were redesigned that year with huge exhausts.)

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?

In the automotive world this is called "presence"

To automotive marketers this type of customer falls under "status seekers"

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…

This is especially true in modern cars with great sound deadening and NVH. As my group of riders has observed when we ferry bikes into winter storage, the only bikes we can hear at all in our cars are practically straight piped.

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?

Such laws are almost never enforced in the US.
