Research on development of highly effective pedaling mechanism for bicycle using link mechanism

我们的目标是把自行车发展到能跑得更轻的程度。关于运动用自行车，我们重新检查了踏板和车座之间的位置，重新设计了新的踏板机构，开发了专用车架，制作了第二个试验模型，并对其进行了评估。关于通用自行车，我们重新检查了新的踏板机构，设计，制作并对其进行了评估。此外，我们还检查了普通基础框架，改进了运动用自行车的机构，开发了一种新的特殊车架，并改进了通用自行车的机械结构，使研究能够推进到实用的地方。我们希望在未来改进该机制，并尝试立即投入实际使用。

We aim at the development of the bicycle where it can run more lightly. About the sports-use bicycle, we examined the position between the pedal and the saddle, re-designed the new pedaling mechanism, developed a special frame, produced the second trial model, and evaluated it. About the general-use bicycle, we re-examined the new pedaling mechanism, designed, produced, and evaluated it. In addition, we examined the common base frame, improved the mechanism of the sports-use bicycle, developed a new special frame, and improved the mechanism of the general-use bicycle, and were able to advance the research to the place where practical use was seen. We want to be going to improve the mechanism in the future, and to attempt putting to practical use immediately.
