Close but missed again, It works by me pushing on the pedals and the bike moves forwards because of my effort... There is a sensor that measures how much I push on the pedals and it sends a signal to the motor to put in 30% of my effort, on top my effort. Thus if I put 10Lbs of pressure onto the pedals there will actually be 13Lbs going onto the effort to move the bike... If I am lazy and only put in 1 Lbs of pressure onto the pedals there would only be 1.3Lbs of effort to make the wheels turn.
