After only 650 miles the Bafang hub motor in my Carrera Vengeance, previously very smooth and virtually silent, has developed a whine and feels a little rough. Performance is still okay otherwise. Am I right in thinking that these are sealed units with no scope for lubrication or other maintenance? (I have very little faith in the "experts" at Halfords).

Your Carrera Vengeance E has a rear hub Suntour motor, not Bafang.
If t's still under warranty, just ask Halfords to help you.
The cause is usually water ingress, rusting the ballbearings.

Thank you for that. I do ride it in the rain so I guess water ingress could be a problem. It is a 2018 model so predates the Suntour update, but is still within the two year warranty. I may have to face Halfords for their expert attention.
