This comes back to the language problem which exists in English, and I think several other languages - the distinction (or lack of) between scooter meaning a motorbike with step-through frame, and scooter meaning a stand up scooter (ie a trottinette).
Arc’s activity type icon indicates the former - the motorbike - but in practice the activity type is used for and usable for both. But that’s not really ideal.
The English language Wikipedia pages indicate this mess quite well - there’s pages for “kick scooter”, “scooter (motorcycle), and “motorised scooter”. A failure of the English language to differentiate clearly.
It seems to me that there’s two things: 1) the step-through motorbike, and 2) the stand-up scooter, either human powered or motor powered.
The difficulty is finding unambiguous names for these activity types. And the language mess extends beyond just English. Which is why I’ve avoided solving the problem so far!
