Love the idea but like most of these type of things it will probably be built with the cheapest of chinese bits stuck together in an irrepairable, economically disastrous hodge podge of poorly matched components.
If the Vectrix https://en.wikipedia.org/wiki/Vectrix couldn't make a go of it with what was by all accounts a well sorted and viable package.
The Fonzarelli http://www.scootersales.com.au/news-reviews-5332/fonzarelli-125-electric-review.aspx
Seems like the Fonzarelli's would be everywhere in the city but I'm yet to see one.Another one that appears to be well sorted.
Cezetas always remind me of the Heinkels, classics with a difference
I share your concern, but there are a couple of things in Cezeta's favour: Vectrix was perhaps a touch ahead of its time; things progressed in the last few years - especially battery technology. In one of the clips this guy says they want to use Tesla's batteries, for example.
For another, Cezeta has something neither Fonzarelli nor Vectrix could claim: authentic heritage.
Also, Fonzarellis might be electric, but they look like any generic Chinese el-cheapo 50cc. This one... love it or hate it, but it certainly stands out :)
Edit: according their official page, it will be build in the Czech Republic. ( ... which isn't to say some components aren't Chinese... I'm sure they are! )
