My invention is a flying bike…　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．　．
