Bicycle that can fly? (7)
I believe the answer is:
chopper
'bicycle' is the definition.
(thesaurus)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for chopper that I've seen before include "Lizzie Borden" , "Air transport" , "Helicopter (sl.)" , "An informal helicopter, or an axe" , "type of aircraft" .)
