How do police bicycle patrols compare with police motor patrols? In this study, both were observed under similar conditions in five cities with populations of more than 100,000. All contact the police officers had with public was recorded and coded. The results show that a higher amount of contact with the public was experienced by police officers patrolling on bicycles.
