Hmmm.... I don't see the difference in the motor except the the difference in Orange and Silver Bafang name plate.
My Bafang plate was in silver colour too, exactly same as yours 500 watts and it was the 1st generation 1000watts wirh Nylon Drive Head. However, Bafang send me the extra "Steel Drive Head" When did you bought your bike with 500watts? Mine was about 6 mths old.
