Hi,
it’s real 
and this picture was taken at Taipei Computex Show few days before you posted it.
from my point of view:
* theft – here in Taiwan, unlikely somebody will push the guy to steal this bike..
* what happens if it rain? is it a waterproof screen? : not sure…
* what happens if there’s a strong wind? will the bike fall? : I guess…
* will pedalling generate more electricity for the battery to run the screens? : not far as I remember
* safety – if the screens draw too much attention to drivers will it cause accidents? : do we prevent hot chicks to go out because they can cause accident?
