Lectric Bike tech support says that the white substances is an epoxy that is found in all of their controllers and that it is not indicative of the E009 controller error problem.
Attached are some photos of the replaced controller that came with the bike in 2020-10. It was opened up and white goo was found it. Not sure if that was indicative of why the controller wasn’t working but I have asked the Lectric team about it.
Lectric XP got an E009 Controller Error at 28 miles. Lectric is sending a replacement controller unit. Has anyone experienced this? And if so, did the error appear a second time some time afterward?
