Ebikes, scooters, longboards: Whatever floats your goat, this is all things micromobility!
"Transportation using lightweight vehicles such as bicycles or scooters, especially electric ones that may be borrowed as part of a self-service rental program in which people rent vehicles for short-term use within a town or city.
micromobility is seen as a potential solution to moving people more efficiently around cities"

It's a little sad that we need to actually say this, but:
Don't be an asshole or you will be permanently banned.
Respectful debate is totally OK, criticizing a product is fine, but being verbally abusive will not be tolerated.
Focus on discussing the idea, not attacking the person.

I know you guys in the US have faster e-bikes, but almost 8 times the speed of sound seems a little bit excessive.
Some countries use commas as a decimal point, but even then, 9.7?
1 mile is 1.6 km with some change, so 20 miles would be around 32 km. If you'd plug the numbers in reverse, that would still give you 12.42.
I can't even imagine how they got that number.
EDIT: Ooooh, they probably asked chatgpt to calculate that, or even to write the whole article.
As an aside, metric conversions of US customary speed and distances are convenient in that they almost perfectly align to powers of two for typical land speeds.
5 mph ~ 8 kph
10 mph ~ 16 kph
20 mph ~ 32 kph
40 mph ~ 64 kph
80 mph ~ 128 kph
The other common speed limits in the USA are thus bitwise compositions, which Computer Science folks might appreciate:
15 mph ~ 24 kph (16+8)
25 mph ~ 40 kph (32+8)
35 mph ~ 56 kph (32+16+8)
45 mph ~ 72 kph (64+8)
50 mph ~ 80 kph (64+16)
55 mph ~ 88 kph (64+16+8)
65 mph ~ 104 kph (64+32+8)
Had the 1980s US metrication effort succeeded, we could have seen those same limits rounded off to: 25, 40, 55, 70, 80, 90, and 100 or 110 kph.
For reference, common speeds around the world are 15, 20, 30, 50, 80, 90, and 100 kph
What, you don't shatter windows all around you every time you go full speed?
