Just keying off your comment about recumbents[1] to drop my new favourite bike obsession since the Brompton[2], the tiny and unusually designed Kwiggle folding bike: https://www.kwigglebike.com/en_US/ which has an upright riding position.
and he has done 186 miles in one day around the Dutch IJsselmeer on it: https://www.kwigglebike.com/en_US/faltrad-300km saying "After the first test drives we noticed two things: the upright riding position is a lot of fun and even after long trips we were not tired at all".
[1] my favourite recumbent to read about/watch is the ICE Sprint with the extra large rear wheel. Worst HN recumbent story is jacquesm and his leg-sucked-underneath incident leaving a serious broken (shattered) leg injury: https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu...
There's a German man on YouTube who is bikepacking with the Kwiggle and a trailer: https://www.youtube.com/watch?v=0HQf71fMuIU
and it's small enough to fold into his canoe: https://www.youtube.com/watch?v=exL-FCqtEOQ
The manufacturer has climbed the Stelvio Pass (1900 meters climb in 12Km) on it: https://www.kwigglebike.com/en_US/faltrad-stilfser-joch
