Riding a bicycle is environmentally friendly and good for your health – so it’s no wonder that 64% of Germans own a bicycle (Statista, 2021a). The number of bicycles in Germany last year was higher than ever before at around 79.1 million (Statista, 2021b). However, if you don’t own a bike, or don’t have it with you at the moment, many German cities offer the option of renting one. So-called bike-sharing systems have become increasingly popular in recent years. In the city of Berlin, for example, there are more than 15,000 rental bikes (Technologiestiftung Berlin, 2019).
