Well, all I needed was to take a step back and think. So this morning I found this:
Andreas Flocken mit seiner Frau in dem zweiten von ihm entwickelten Elektrowagen, luftbereift, mit Spurstange unten und der Batterie vorne. Das Foto stammt aus dem Jahr 1903
Andreas Flocken with his wife in the 2nd electric car, which he developed. Pneumatic tires, batteries at the back. Photo is from 1903. Flocken lived and worked in Coburg. "Spurstange" is a kind of steering.
