The electronics are all built into the unit. Apart from the gear issue I had two fail electrically. The second one did about 50 miles before failing. Cheap Chinese components in my opinion. As for the gears they were totally the wrong tooth form. Skew gears need a bit more skill than straight cut gears but the sellers refuted any claim that the gears were wrong. Compare the price of the dynamater to the price of a properly converted dynamo. That will suggest why they tend not to last.
