Hello p0pak,
welcome at Stridaforum 
Well…either a pretty old 5er series Strida - or an (optically well done) fake.
Suspicious are for me the brake rotors (don’t remember to have seen this shape) and the three clamps at the seat molding (original two I think).
Anyway are the brake rotors mounted the wrong way - disregarding their prescribed running direction!
A (relatively) certain sign of a genuine one is the serial number at the underside of the bottom tube, close to the rear hinge - is there a number present?
