A police bicycle is a bicycle used by police forces, most commonly in the form of a mountain bicycle, used to patrol areas inaccessible to police cars or cover a wider area than an officer on foot.
Bicycle patrols are often assigned to locations that police cars cannot access and that officers could not effectively cover on foot, such as dense urban areas, pedestrian zones, and public parks. The maneuverability of bicycles and their ability to navigate narrow and densely-packed areas easily and quickly offer advantages over police cars, though bicycles are slower than police cars, carry less equipment, and cannot be used to effectively enforce road laws, though they may still conduct traffic stops if possible; for example, a video of a Japanese bicycle officer stopping a Lamborghini Huracán, despite the massive speed difference between them, went viral in 2017.[1]
