Some bikes designed to transport different cargo, inspired by sounds_sound's tiny bike-house post.
I've sort of wanted to do more biking, but my state is very seasonal, and when the warm weather hits a pedal bike just can't compete with my motorbike. I still maintain a small bit of bicycle envy though.
These bikes are quite common in the Netherlands. People use them to transport small children, dogs, large loads or just to get somewhere. Especially popular among young parents nowadays.
