Ohh I found some more angles of the red one!
Looks like it's a narrow single bed, but the bed folds up and a table folds out to make a kitchen area!
I'm not a fan of the trailer design though, I think it would be more fun if it were built into the back of an extended wheelbase trike, which is what I would do if I ever built one of these.
@Nonverbalpoetry oh, absolutely. I've brought gas bottles home from town in the trailer (35kg or about 80lbs), and that was really scary on the downhills. The cargo bike is a lot more pleasant with a heavy load.
