it's a brand new bike; ideally it would be built the correct way right from the start with sliding vertical drops.
I suspect that the tensioner is the easiest way to adjust the belt. My belt drive bike has an eccentric bottom bracket, I think I would rather have had a tensioner; but that is because it would then be possible to add a mid drive electric motor. I doubt that would be a concern for most users.
