T-bike is committed to reducing the number of abandoned bicycles in the school. We hope that students will not only learn how to repair and maintain bicycles through the process of practice. I also hope that they can further think about how the problem of abandoned bicycles came about, how to solve it, and design feasible methods. And hope that the gains they have gained during the service period can be used in all aspects in the future, and together they will do their best to reduce waste. The course is mainly conducted in the form of experience and practice. Through the hands-on process of service learning, students understand the structure of bicycles and learn how to maintain them. In addition, there will be some discussions in the course, allowing students to think about how T-bike can approach our goals, or what new ideas and ideas can be implemented.
