When cycling, fiercely criticise electric car (5)
I believe the answer is:
tesla
'electric car' is the definition.
(I've seen this in another clue)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for tesla that I've seen before include "Physics unit" , "Californian company specialising in electric cars" , "Inventor" , "Physicist" , "Unit of magnetic flux density" .)
