Electro Cargo Bikes for Hire in Cologne

I came to Germany about 40 years ago. At that time most German young men drank beer. If a visitor came round it was usual to offer them a bottle of beer, so every two or three weeks one would buy a crate of beer. In those far off days one normally used a car in order to drive to an out of town supermarket to pick up the beer. Trolleys, bike trailers and cargo bikes were unknown. I did not have a car so would walk round to a local shop and stagger back with 20 bottle crate causing my fingers to gradually numb. These days we drink about a crate of beer annually and now there is a possibilty of hiring an electro-cargo bike, in Cologne at least: www.donk-ee.de.
