I am 1m96 / 6 foot 5 inches and normally use a very large road bike i got used. Are there any tall people who can post a review of your experience with the ezee torq?
I'm not in a position to judge other then to say that a 5' 6" person can only just manage on the Torq, so it is biased towards the tall.
If you don't get an answer later, perhaps a test ride is possible. Here's the contact details for eZeebike in Germany where you live, as they may be able to organise one for you:
6 foot 3" here Torq owner here - the Torq is perfect for a taller rider. I think only the Torq has the big 28" wheels so you can really feel king of the road...don't settle for second best...
