Good morning, ladies and gentlemen. I'd like to introduce my new invention to you.
It is a flying bicycle. I think it's really a great invention. It has two wheels and a pair of wings so that we can either ride the bicycle on the ground when folding its wings or fly in the sky.
Besides, we can take photos or communicate with others with it.
What's more, it can not only reduce traffic jams, but also help to protect the environment because it uses solar power as its energy.
Although it has many advantages, it can be improved to be more helpful. It will be made of lighter materials so that people can carry it easily. Also, we should add something to the bicycle to stop people from falling off it.
As a helpful invention, I think it will be more and more popular in the future.
