Hello Harty,
welcome to Stridaforum!
I suggest to start here Keep Strida Original - say NO to Fakes!
You can find here more info about fake Stridas = SLO’s (Strida Like Object).
Furthermore you might use the forum search, using the term “SLO” you will find 68 matches with tons of informations.
And if you would show us details of your bike, we could help to identify it
