Thanks remmie and Hans2183 !
As a total tech-dummy this all is completely new land to me ....
I plan to buy the bike only next year - was never on a heavy motor bike before and will have to learn to ride genuinely. (I'm bicycling and drove a moped some 40 years ago ...).
It will surely be the premium version and I assume that in the end I also want the rapid charge option. I'm not sure if I will order that from the beginning or if I want to start without it and first have a look and feel how things evolve. In the latter case I nonetheless would buy the 3 Pase 32A version fromt the start).
Regarding charging at home (living in a rented flat); we got a free T25 socket. I guess that exists only in Switzerland
https://www.plugsocketmuseum.nl/Swiss_3hd.html . One internet source sais it's 3L / 3x400V/16A; 230V/16A.
I wonder if I could use this one somehow. However, I'd need a cable of about 15 - 20m length ...
So - no idea if that would work and what I'd need for that. I think I somewhere read that electricity home installation is not designed for heavy use like 3x400V/16A over a long period. I guess I will have to ask an electrician.
Also I have asked the owner (pension fund; building with 10 flats) if he'd be willing to install a wall box. Then I would not need the solution for the T25 socket. But I'm not very confident that the owner will do it. I'm just checking my options in advance ...
