It's strange to see an eight-minute video about a trike in which the trike doesn't move. Maybe that's understandable, since it must be terrible to ride - it certainly is narrow, and that's a bad thing in a trike. It must be necessary to slow to a crawl or lean like sidecar racer to go around a corner. We have an adult trike of the same format (upright, two wheels in the rear) and it's much wider.
I agree with John that it doesn't look like it folds very well. It appears to be a folding bike with the rear replaced by two wheels, with nothing done about the fact that this keeps the front from folding properly against the back, but this image from the manufacturer's site
shows the front wheel tucking in reasonably well:
It's still a substantial package, the seatback is unfortunate, and the handlebar appears to be removed and just dumped on the rest (limited by the cables attached to it).
