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?

The EPA prohibits modifying exhausts on motorcycles to exceed some decibel limit (80 something IIRC?), and this is stamped into the muffler on my motorcycle.

Loud pipes are annoying, but they won’t change the amount of vibration transmitted through the handlebars to a phone mount.

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

I'll keep that in mind next time a loud bike wakes up my children in the middle of the night. "It's okay honey, that man needed a psychological safety blanket.'

My kids would find that hilarious, and I'd have to resign myself to hearing it after every motorcycle that passes for weeks.

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?

I wonder what the signs of degradation are? I use my phone attached to my handle bars and the phone shakes so much that I can have the camera app open and see the picture vibrating, it won’t actually let me take a picture or video. If I start the video then the bike it will record but blurry. I’m on an iPhone 8 so might have older camera less sensitive to this.

Road bikes too. I wrecked my iPhone 8’s autofocus after riding ~1000 miles with it on a handlebar mount. Obviously there’s no engine vibration but chip-and-seal roads have a similar effect.

I've read the same, but my Pixel 3 had no issues after ~12.000km, half on it on asphalt, the other half on gravel and some rougher parts. Then a Motorola and a Xiaomi which I guess shared each half of the ~12.000km (two phones mounted, Xiaomi replaced Motorola halfway, both in parallel to the Pixel 3), where both of these devices (not the Pixel) were making automatic photos at geofenced spots during the ride (one of the street, to record the wet/dry condition, one of the selfie camera to record the sky condition cloud/sunny).

Though I do use a rubbery holder with good damping properties [1] and only recently moved over to a fixed one out of aluminum [2] for one of the phones, which could start causing this issue.

> 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 also be challenging to accurately model the resonant frequency response of composite "stuff" prior to manufacturing it (many bridges have failed). Better luck with the next model I guess...

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

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 plo…

It sounds equivalent to driving your car around with the horn constantly pressed for safety. Why not get a horn or something for your bike? Or wouldn’t that sound as cool?

This!! Mufflers and subwoofers wake up my child in the middle of the night and only we know how long it takes to fall asleep again. Its frustrating because both of these sources are completely unnecessary

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 b…

It is kind of inevitable in the long run if cars move on to being EVs, where will bikes fill up if there are no more gas stations? That being said, I’ve only ever seen one EV motorcycle in China once (not just a big electric bike), it had unreal acceleration, I’m not sure it would be safe to ride.

Thing is... there will likely always be gas stations catering to vintage vehicles and such. Bikers will have to pay premium for bio-ethanol or such meant for exotic and old cars. Luckily motorcycles are generally decent (not great) on gas mileage, so it might work out OK.
