New Brose electric drive system

I gather that a new EU law is in effect, requiring a fake noise to be generated for e-cars traveling at less than 12mph.
Won't be long before a similar law comes into effect for e-bikes, which generates a puffing and panting sound with random creaks.

My Scott e-bike has a Brose motor. Perhaps not the exact motor shown in the page linked to because the bike is a year old now. However, the bike itself is the same shape as the one shown in the page with the battery being integrated into the frame. I don't know whether this is the best motor/system to have but I find it does the job very well (up to 16 MPH) and doesn't make any appreciable noise.

I had to return the bike to the shop a couple of times because of a battery charging problem. The battery took no notice of the charger being plugged in and wouldn't charge at all. A bit of trial and error was needed (resetting - turning off and on) to get it to charge. The problem was eventually cured by a firmware upgrade and it has been no trouble ever since.

I'm well pleased with the bike all in all.
 
This looks interesting, a new drive system claimed to be whisper quiet with belt drive;

The 'whisper quietness' and belt drive of Brose motors is not new, they've been making them for a while now.
My friend has a Specialized Turbo Levo e-mtb with a Brose motor, and it is virtually silent, even on smooth tarmac you can't really hear it riding alongside it.

Yeah, I wish those Gates belt drives didn't add so much to the cost; I've been looking at some of the e-folders that use them here and they charge a premium for them. And they even make the Bosch systems quieter!
