Bicycle counter in Copenhagen.|alt= Bicycle counter in Lahti.|alt= Bicycle counters are electronic devices that detect the number of bicycles at a location for a certain period of time. They are sometimes referred to as bicycle barometers, but the term is misleading because it indicates the measurement of pressure. Most counting stations only consist of a sensor (and the internal computing device ) and some use a display to show the total number of cyclists of the day and the current year. There are counting stations all over the world in over hundreds of cities, for example in Manchester, Zagreb, or in Portland. The first bicycle counting station was installed in Odense, Denmark, in 2002. To increase visibility, bicycle counters are mostly installed at positions with high traffic volume and visibility to a range of road users.  They have been called urban visualizations and fulfill certain criteria of ambient intelligence, such as being embedded, context-aware and adaptive. Bicycle counting stations can be described as persuasive technology. Technical Setup A bicycle counter in Mannheim with pneumatic hoses to detect the number of cyclists. Narrowed passage at the Tisza Cycleway in Hungary with cameras to count cyclists. The technical equpment of a bicycle and pedestrian counter next to a cycle path, using an infrared sensor in Burlington.|alt= Different techniques are used for detection of bicycles, such as built in induction loops,  pneumatic hoses, infrared sensing or cameras. Different setups provide different advantages such as more precise counting, battery life, reduced costs or differentiation between different road users such as cyclists, pedestrians or cars. Pneumatic tube setups are said to have an accuracy of 80\% , manufacturers state a 90\% accuracy for induction loops  Criticism There has been criticism on the precision of the counting and on the cost of bicycle counters as a waste of tax money (14000-31000€)  .

Bicycle counting stations can be described as persuasive technology. Technical Setup Different techniques are used for detection of bicycles, such as built in induction loops, piezoelectric strips, pneumatic hoses, infrared sensing or cameras. Different setups provide different advantages such as more precise counting, battery life, reduced costs or differentiation between different road users such as cyclists, pedestrians or cars. Independed testing have shown that pneumatic tubes can record with over 95\% accuracy and piezoelectric sensors reach 99\% accuracy. Manufacturers state a 90\% precision for induction loops . 219x219px|Piezoelectic bike counter in Haarlem, the Netherlands.
