Interesting device.
I could imagine they missed their calling 20 years ago before POT legalization.
I'm trying to imagine if they'd be useful for hiking/camping.
If I was going to build one, it would be primarily for access to flat-land camping sites. So, folding and compact would be a MUST. Perhaps design it around the Schwinn 16x3 tires.
However, the E-Cart could be handy for more rugged terrain. It mentions hunting.
