Re: thinking about a motorized bike for pedal assist
On the China 2-strokes in stock configuration, the extra resistance comes from having a chain and sprocket on the left side. When you're pedaling, you're driving that sprocket and chain which is connected to the motor. Even with the clutch in, there is still a bit of resistance. I personally don't like to pedal my bike if I don't have to....it's much harder.
