Welcome!
 
I'm a little envious of the vast selection of e-bikes you have in Europe.  Was the "BMW Cruiser" a car or e-bike?  (I ride a BMW GS motorcycle.)  And I'd never heard of Kalkhoff...  and now I see that some models are available here in Canada.  Looks pretty good!
 
Please let us know what you think of the bike after you've put some good rides on it.
