I can't identify the manufacturer nor the year it was produced.
It has a serial number on the frame, just above the front fork, something like 93042829 or so what (peculiarity: the numbers are engraved head down).
So, can anybody help me, please?

Looking at the integrated shaft and the style of bike it could be from Arcade. I can't see the bike in their current catalogue, but that's hardly surprising. Maybe if you contacted them directly they could help you out.
This is the key part of the only shaft drive bike in their 2016 range:
I think this Chainless drive aka "Sussex Drive" I came across a brand or model called Dynamic which had the same odd bend in the top tube.
