Amsterdam is the capital city of the Netherlands located in western Europe. It has a population of over 811,000 people in the city itself and 2.3 million in the metropolitan area. The city has prioritized bicycles as a main form of transportation, with over 800,000 bikes. In the 1970s, when driving was increasing and cycling decreasing, the city took action to promote cycling by implementing bike lanes, bike parking, and eventually banning cars in the city center on Sundays. Now over 60% of trips in Amsterdam are made by bike due to extensive cycling infrastructure and bike-friendly policies.
