Along the new Green Path that slices diagonally across Copenhagen and Frederiksberg - a kind of motorway for bikes - the City of Frederiksberg has set up a 'Cykelbarometer'.
It counts the number of cyclists that use the new pathway system each day.
The idea is to encourage more people to ride by showing how many are using it.
It is rather new, so the total number is only about 70,000. But the maximum for the year is 1 million. By the way, the sign isn't broken, it's just my camera that couldn't register the diodes.
On the left it will show last years total, once we get that far.
