ENVO UPT -- clever design. I love its versatility! Also, SWAPPA Zip is one of the nicer mini EV's I have seen. The MIA 2.0 was my favourite of the bunch for its numerous cool conversion options -- Top Marks!
Mini EVs depending if you can remove the batteries for recharging and safety. The EV battery technology the problem is thermal running away were the battery catches On fire because if there is a flaw in the manufacturing of the battery or gets damaged in some way becomes un safe. If you have small battery packs that can be removed for charging and can be protected from damage when in use. The mini EVs will be good for inner city driving at slower speeds.
