Abstract
A cyclocomputer for use on a bicycle displays route instructions stored in the cyclocomputer, displays two dimensional graphs on the face of the cyclocomputer, and is capable of exporting and importing information to and from other computers or cyclocomputers. The route instructions may be displayed with symbols such as left arrow, right arrow and up arrow or with alphanumeric characters. The displayed instruction is advanced to the next instruction automatically when a predetermined distance has been measured by the odometer or by the press of a button. Button presses may advance or review the displayed instructions. The distance to the next instruction point is constantly displayed. Importing information may be accomplished with an infrared link which communicates to many cyclocomputers at one time. Recorded data, such as speed, pedal cadence, or heart rate, may be displayed over distance or time, with the graphs being marked for each instruction point.
