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．．
