To observe one's own motion in real time is very important in improving one's sports skills. A growing number of people are enjoying cycling as a sport. Their riding skill has to be improved for keeping their safety. Then, we propose a system that presents riding states to a bicycle rider for improving his riding skill. Though there are many elements about riding states, especially in this paper, we focus on the balance of the load applied to some points of a bicycle; a handlebar and a saddle. Finally, we verified that the proposed system is effective through an experiment.
