My invention is a flying bike… It is fast，convenient and green!

The flying bike has two wheels and two wings．It has a top speed of 300km/h，You can go to farther places in a shorter time．

It can run on land and fly in the air．If you shout"fly"the bike will turn into a plane in 30 seconds．Then you can fly in the air．You will be as free as a bird．It can take photos，too．

Instead of petrol，the bike uses solar power，so it will not pollute the air．

I will add a seat behind it so that it can carry two persons．

My invention will help people live a better life in the future． ．
