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.
Yeah, they're novel designs for sure but I'd rather have a Brompton or a Tern. I've had my eye on a Link D8i for a while now and one day I'd love to be able to afford a Vektron...
