Therefore, people hope that the function of amusement, leisure and exercise of bike become more and more; and bring more health and happy. As one import auxiliary function of bike stopwatch develops quickly. The design of stopwatch is scientific, reasonable and beautiful; and it also has its practical value. Stopwatch can calculate speed and distance, reflects true exercise state; based on this exerciser can adjusts exercise strength so that it can reach the best effect of healthy exercise. This project takes SST89E516 MCU as main control chip and takes 128*64 LCD as terminal display which displays speed per hour, distance and system set. In the system set menu people can set install information to improve measure precision. Besides, it appends alerting function. When reach the distance and speed set in advance, the system will alert automatically to remind exerciser that he has reached exercise strength set in advance. This project mainly includes bicycle wheel pulse acquisition, keyboard input and data shows. The main program is compiled by C language which is to do initialization and keyboard dealing; the compiler and simulation download of program are done by Keil C and SSTFlashFlex51, and the various functions of the bicycle are realized concretely by the SCM experiment development board. Key words: AT89C51 single chip microcom
