It was made by me and my friend last week. I think it’s really such a great invention. Here is my introduction to it. It has two wheels and two wings so that we can use it to ride on the ground or fly in the sky. Besides, when we ride the bike, we can take photos or call others with it. What’s more, it can not only travel very fast, but also help to protect the environment and save energy because we use solar power to move it.It has many advantages. However, it can be improved as well. First of all, we had better add something to the bike to stop us from falling off it. In addition, it’s a good idea to set an umbrella on it to help us keep off the rain. 展开更多...... 收起↑ 资源预览
