In 1891, the department first purchased bicycles to serve with mounted police. The practice of using bicycles would wane throughout the 20th century, but would see a revival in 1993 as they served as an effective alternative to motor vehicles. Three Cadillacs were purchased in November 1908 to address the problem of lawbreakers making getaways in the "horseless carriages." In 1932, the Louisville Police Department began using radios for dispatching units, only the fifth department in the nation to dispatch cars in this manner. Motorcycles were introduced shortly after the cars, but were discontinued in 1984 due to high maintenance costs.
