This bike is from Azor( https://www.azor.nl/azor-fietsen ). It’s a Dutch design and you can even combine it yourself.
This one is a bit older but there are still many models who can carry a small dog or bigger dog. My main advice is that that the luggage carrier is attached to the frame and not to the handlebars.
Storm weights 35kg. I have tried smaller ones and bigger ones but this is my favourite.
Freistaat, no problem. I know how difficult it can be to find one that’s fits your wishes.
For me it is no problem. It was with the bike that had the carrier on the handles... but even though the weight is quite hi above the ground it is right above the wheel so there is no real lifting there.
