Great choice!@Ravi Kempaiah thanks for the great input. I decided on the Six50 E2, special ordered at the LBS and ordered a bodyfloat seatpost. The Supernova looks awesome but will have to wait on that for now.
Thanks for the suggestion on changing the front chainring to a 20T, that's definitely do-able!
It was a mistake by BULLS that they left out the front chainring to be 15T (EU spec) while all other speed pedelecs have 20T or 22T.
The bike frame geometry is a very versatile one and I am sure you would enjoy this immensely.
