Traffic jams have appeared in many places of our country. So in the future, many interesting means of transport will be born by humans.
My dream means of transport is skycycling. In my opinion, it will br powered by solar energy and wind energy to avoid pollution and save fuel. Two people can sit on it. We can use it anytime and anywhere. It's won't take a lot of space. I think it will look a big tube. People will pedal to move tubes in skyrails. With the use of morden techndogy, skycycking will be able to help us many things and it will make our life become better. Skycycling will be able to avoid traffic jam, pollution and it help us comtemplate sky more clearly.
And in the future, I hope people will make skycycling is the same as my dream.
