Hard to see most of these being more practical than, say, a Brompton folding bike. But I like the see the creativity in this space.
I could see this being a lot more practical to carry around. I have a Brompton and a Uscooter. and while carrying them around is doable they are certainly not small to have on you.
Something backpackable is probably subpar to ride for long distances, but likely easy enough to just always have on you.
I’d love to get a Tern Vektron lol, these things look pretty gimmicky though.
