A cyclocomputer or cyclometer obs. is a device mounted on a bicycle that calculates and displays trip information, similar to the instruments in the dashboard of a car. The computer with display, or head unit , usually is attached to the Bicycle handlebar handlebar for easy viewing. Some GPS watch es can also be used as display.
