Category talk:Electric motor scooters

Aren't all electric motor scooters and motorcycles battery-powered?

Presently Category:Battery-powered motor scooters‎ (containing only two items) is a subcat of Category:Electric motor scooters. Is this needed? I mean, are there any electric motor scooters that aren't battery-powered?

A similar issue exists with Category:Battery-powered motorcycles and Category:Electric motorcycles, and in fact also there is Category:Electrically-powered motorcycles. What is the difference? ITookSomePhotos (talk) 15:38, 7 November 2022 (UTC)

There are already fuel-cell motorcycles. This is a kind of electrically-powered vehicle. Trigenibinion (talk) 17:18, 7 November 2022 (UTC)

I understand that electric and electrically-powered are the same. Trigenibinion (talk) 17:19, 7 November 2022 (UTC)

There are also fuel-cell scooters. Trigenibinion (talk) 17:23, 7 November 2022 (UTC)

@Trigenibinion: I see, thanks; would you say, however, that 99-100% of the electric scooters here presently not under Category:Battery-powered motor scooters‎ are in fact battery-powered? ITookSomePhotos (talk) 18:05, 7 November 2022 (UTC)

I think a lot of BEVs have been tagged only as electric here. Note that PHEVs are considered electrically-powered. Trigenibinion (talk) 18:29, 7 November 2022 (UTC)

Maybe you would be also interested in motor trikes which get classified as tricycles (the fact that some filenames have this word does not help). Trigenibinion (talk) 18:35, 7 November 2022 (UTC)

Do you (or anyone) think that all the battery-powered electric motor scooters should explicitly go under Category:Battery-powered motor scooters‎, or could the default for Category:Electric motor scooters be battery-powered, and only the non-battery types need subcategorisation?

The general way it is done in commons is to have a BEV category under the EV one. It is wrong to place BEVs directly in an EV category if some non-BEVs have been or are being developed. Trigenibinion (talk) 11:20, 9 November 2022 (UTC)

OK, sadly I can't see myself going through 125 images and 39 subcats, determining whether they are battery-powered, and manually changing the categorisation. If it's a fair assumption that all are battery-powered, then I guess it could be done with an automated process, if anyone knows how to do that. Also, I notice that the "Wikidata" box lists "electric scooter" as "subclass of battery electric vehicle", which, from what you say, also is wrong (or not necessarily always true).
