When you contacted Eahora support, did they fully understand the problem? I have been going back and forth with them on this same issue for over a month and they still don't get it. After a couple weeks they seemed to have understood the problem, saying: "Our technical staff said that the current ratio of the current output of the current 18A controller in the throttle mode and the PAS mode is 1:1, which means that the current output power in the PAS mode can reach the current in the throttle mode, but this will reduce the mileage that a bicycle can ride in PAS mode." Based on that, I ordered a new controller, but it performed exactly the same as the old one. Now they are saying that I can change the setting through the display, but the video they sent showing how to do it doesn't help... besides, I have tweaked every setting possible and there is no change. Now they want me to do a video showing that the controller is limited to 6 Ah in PAS mode. I need to set up a GoPro and send it in to them. Hopefully, that will convince them. I keep scratching my head, though. Does this support team have any bikes to ride and see for themselves what is going on?
