The last one is the nicest one of the set. Still, all the models shown use the form factor of the mountain bike. And that is not the best one for urban use. Great for exercise, yes...but that also means lacking in comfort, making most people not want to use them for a quick trip to the store or other common day use...defeating the whole point of the bike.
Bicycles in the Netherlands are shaped for comfort and as such much more popular, making people actually want to take the bike instead of a car/motorbike. China uses similar shaped bikes as the Dutch and there the bicycle is also very popular/useful.
Most designers are too locked in their thinking and flood the market with slightly more clever mountain bike models.
