Mudguard set for e-bikes R6 / R6 Neo / R8 Ranger / R8 Flex II

Everything was fine during the test drive, but after just 35 km the connection between the motor and the display could no longer be established - and this while on holiday in France. The attempt to find a solution to this via the service hotline and emails is simply an absolute disgrace: incompetent staff, endless latencies for simple questions via email, no useful options or implementable suggestions! I would never buy the bike again, I will definitely return it!

I think that the installation of the front mudguard was only a guess, even from the pictures. The nut that sits on the screw to attach the panels started to turn at a certain point, so that it was not possible to tighten it properly. I used another solution, but it wasn't ideal.
The rear mudguard and luggage rack were self-explanatory.

Maybe you can help me with another matter?
I can't find the key for the battery anymore. Is there a way to get replacement keys?
Kind regards, Siegfried Dobel

The mudguards are easy to install and definitely serve their purpose.
You can only be satisfied.
