It's a public tire pump. It's so ridiculously bike friendly here. In fact, the street I live on is "gäller ej cykel" or basically bike and foot traffic only. My grocery store has bike tubes (Dunlop valves!) and all different kinds of accessories, but no dryer sheets or clothing hangers :-(
The laundry is free, but you have to book your time by locking your device into a time slot for the month, then you can rebook the next time after you do your laundry. It's a bit unusual and most people have a hard time understanding.
