I like the mini part, but no way that's carrying any kids+stuff anywhere, realistically. I also don't get all the proprietary moving parts and gimmicky junk associated with it.
Lockable box would be very handy for storing say the cover, and the battery are my thoughts. I don't need loads of cargo space (currently get most of my kit on the back of a Tinker), and I reckon you could easy squeeze a person in there lol.
This looks great. Better start saving lol.
