Hello Thomas,
generally are all pictures too bad to be sure for 100%…
but…hubs, cranks, rotors and kickstand are looking suspicious…
And there’s a lot more:
At the golden steering tube one can recognize an area of different color,
suprisingly just close to the locking mechanism 
The L-shape of the locking mechanism’s frame ears is different from original,
(the outer shape seems rectangular which the original is not)
- just a guess, but maybe there were new ears welded onto the frame tube?
Look at the black seat tube - it is bent! 
I’d ask the seller if he knows that Ming cycle might sue the abuse of the name Strida…
Please be very careful if you want to buy a used Strida - even it’s definitely a genuine one!
Good luck,
Chris
