police bicycle
A police bicycle is a land vehicle used by police departments, most commonly in the form of a mountain bicycle. They are designed to meet the requirements unique to each department.
The maneuverability of these vehicles on crowded sidewalks and their ability to navigate narrow, crowded driveways offer advantages over cars, although a bicycle's top speed is lower.
Bicycle patrols are more common in temperate urban areas where limited coverage areas are available. The use of bicycles instead of cars can make police officers more easily approachable, especially in low-crime areas. Bicycles can also be issued to police officers to enhance the mobility and range of foot patrols. Bicycles are also effective crime-fighting tools when used in densely populated urban areas. The bikes are nearly silent in operation and many criminals do not realize that an approaching person on a bike is actually a police officer. Furthermore, if the criminal attempts to flee on foot, the riding police officer has a speed advantage while able to quickly dismount if necessary.
In the average hour, a patrol car would have 3.3 contacts with the public, while bicycle patrols had 7.3 contacts with the public. The average number of people in contact with the police per hour was 10.5 for motor patrols and 22.8 for bicycle patrols. This information tells us simply that the activity level of police officers on bicycles is higher than that of the officers in cars.〔
