These photos are of public bicycle tool kits provided by the ANWB in the Netherlands. Both are on the outside walls of cafes, the first is near Assen (at the link you can see the beer company sponsored cycle parking and the nearby cyclepath as well as the toolbox).
If you need to use the tools inside you can get a key from the cafe owner.
The ANWB is the Dutch equivalent of the Automobile Association.
The letters ANWB stand for "Algemene Nederlandsche Wielrijders-Bond" or "General Dutch Cyclists Union". The organisation that rescues broken down drivers in the Netherlands is actually a cycling organisation. They also put up many of the cycle route signs. In the 1970s there was a lot of criticism of the ANWB for no longer representing cyclists enough, which lead to the formation of the similar named ENWB ("Eerste Enige Echte Nederlandse Wielrijdersbond (ENWB)" - "First and only real Dutch Cyclists Union") which later changed its name to Fietsersbond ("cyclists union") and today campaigns for cyclists rights.
The second photo shows another toolbox on the outside wall of a cafe near Eindhoven, in the province of Brabant several hundred kilometres from here. Note that this also has a "Fietscafe" (cycling cafe) sign. It's one of hundreds of fietscafes in the Netherlands. The province of Brabant, for example, has 200 Fietscafes.
There are photos of other small things like this on the blog.
"Fiets" is one of two words for bicycle in Dutch. The other being "Rijwiel", hence the name "Rijwiel hulpkist" for the public tool box.
