It's basically the same mechanism that made Tesla succeed with early BEVs where others failed: if the 4000€ e-cargo was a Model S the trailer would be a VW City

It's basically the same mechanism that made Tesla succeed with early BEVs where others failed: if the 4000€ e-cargo was a Model S the trailer would be a VW Citystromer. Another factor is that plenty of people permit themselves to go electric with a cargo bike who wouldn't dare getting seen on a regular bike with assist. "I'm not that old!". I believe that plenty of people have eventually caught themselves making up excuses why this particular ride could maybe require the load capacity (and chances are they were amused by it that's how deep the positive associations go). And lastly, while things like https://schokofahrt.de/ https://schokofahrt.de/ would certainly be possible with trailers (I'd actually be surprised if trailers have never been part of it), it's just not part of the brand.
