It is a special bike with two wheels and two wings. The flying bike can drive both on the ground and in the air, and it can be used to take photos and people can talk with it. As a very special bike, it is fast, and it is environmentallyfriendly because it is driven by solar energy. This is my flying bike, which is made by myself alone in my spare time. If it is made real, I will have two improvements. I will suggest the engineer use light irons of high quality to make the frame, and make the wheels as large as possible.Thank you very much.
