Leonardo da Vinci invented the bicycle and the helicopter.
He did not invent it he 'visualised' it and drew his impression
The aeroplane he sketched was supposed to flap its wings.He also invented the helicopter.
He invented a spiral contraption that is similar to a modern day design of the helicopter and also built wings that he thought could make a person fly but later realized that birds have hollow bones whereas people have heavy, solid bones. Other than that, I don't know... Hope I helped.
