That's a new problem. The display/controller should light up automatically when the charger is attached, assuming the cables are connected and not broken. See attached owner's manual. Did you put a voltmeter on the battery +/- leads before or after the charging? You should see around 40 volts after charging. I suspect charging was not successful even though the charger went green. Hopefully that is the case, since a problem with the display or the charge board would be probably not be fixable. I had to open the battery hub and charge the cells individually to recover from a totally self discharged battery.

I've got time either Sat or Sun if you want to come south, but I'm not sure I can be any help if it's a display problem. I've never done reset and don't know how. We could swap displays to test, but I understand they are specifically programmed for an individual bike. Even if no work, they still should light up when swapped and give an error. That would be some info.

If either the display or the charge board inside the font hub are bad I think you are stuck trying to restore the bike. If i were in those shoes, I would scrap the front battery and the display. I would open the rear hub (motor), disconnect the controller inside the and bring just the 3phase wires and the 5 hall sensor wires and connect them to a 1000w external controller with a 48 to 54 volt battery. You loose most of the nice E+ featrure and you still have a very heavy bike, but it would be faster and totally reliable
