<p>In this paper, we investigated energy distribution of a sports bicycle for evaluating the acceleration performance quantitatively. As the input force for measurement of the performance, constant weight was put on one side pedal of the bicycle positioned on a running roller, and the rotational speed of the wheel was measured under various conditions. The acceleration performance was then calculated by dividing the increased rotating rolling energy by the input energy. The result shows that almost 60% of the input energy was used for the acceleration of the bicycle. In addition, we also investigated influence of the wheel weight (moment of inertia) and air pressure of the tire on the performance. As the results, the performance was increased about 5% by the 30% reduction of the inertia. On the other hand, the performance was observed to decrease about 4% by the 30% reduction of the tire pressure. From these results, we could obtain the influence of the wheel and the tire characteristics on the acceleration performance of the sports bicycle quantitatively.</p>
