Here's my cargo bike: (non-e variant): [1]. The company got bankrupt a couple of days ago.

It has three wheels. Two smaller ones at front, one back. As such, I'd prefer to install the motor on the back. We do have that speed limit of 26 km/hour (my current e-bike has it as well), but since more force is required, the kit would need to know this as well.

I got it second hand, same as my e-bike. Otherwise, these aren't affordable for me. 6k EUR for a cargo e-bike is just insane IMO.
