As a person who would be the target market for one of these, here's why it's worse than the competition:
a) if you're going to have a full length bike that doesn't fold, use something resembling a fat 29er (700C) mountain bike frame. It'll be much more rigid. And the user can do things like put a water bottle cage or two on it.
b) 700C gives a much, much wider choice of good quality tires for road, cyclocross type tread pattern (like 700x32), and crosscountry mountain bike type width and tread pattern.
c) the totally nonstandard crankset and crankset ring size mean that you can't easily find parts for it, compared to the cranksets and ring sizes you would see for a suspensionless 700C city bike based around a drivetrain like 2x10 or 2x11 in front, and 11-34 cassette in rear. crankset rings for use with 20" size wheel folding bikes are much more rare than normal size rings.
edit: more:
d) no specification on what derailleur it uses, what shifters/brake levers, no specification on what disc brakes it uses. which in the "serious" bicycle market ($2000+) usually mean junk. I want to see specific shimano or sram part numbers there.
