Best E-Bike-selfbuild-set to buy in Germany?

[Lyo]

Hey guys,
I finally want to get myself a solid and fast e-bike. (Fully MTB Frame // 40km/h+)

And this is the frame I wanna use:

Is there a good price/value BAFANG MXUS 52V or similar e-bike set to buy in Germany?

Any advice much appreciated!
Cheers
