This afternoon one of my colleagues in the lab asked if I could give him a hand carting in some full water bottles for the cooler in our lab. His car was parked fairly close by, but it still would have been a bit of a chore to cart 4 x 12L bottles in. So I suggested we use the bakfiets, since this is the kind of thing it is designed for.
I rode around to the back of his car, and we put all straight in, and before we knew it we were unloading the bottles and carrying them up the stairs to the lab. Very easy and very efficient.
