Cyclocomputer
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 handlebar for easy viewing. Some GPS watches can also be used as display.
==History==
In 1895, Veeder invented the ''Cyclometer''.〔''The Horseless Age'', New York: The Horseless Age Company, Volume 40, No. 1, (1917), p. 58〕
〔 〕 The ''Cyclometer'' was a simple mechanical device that counted the number of rotations of a bicycle wheel.〔Veeder-Root, Inc., ''(Veeder Root History )''〕 A cable transmitted the number of rotations of the wheel to an analog odometer visible to the rider, which converted the wheel rotations into the number of miles traveled according to a predetermined formula. After founding the Veeder Manufacturing Company, Veeder promoted the Cyclometer with the slogan, ''It's Nice to Know How Far You Go''.〔Veeder-Root Inc., ''Veeder-Root History''〕 The ''Cyclometers success led to many other competing types of mechanical computing devices. Eventually, cyclometers were developed that could measure speed as well as distance traveled.
