I ordered the bafang g062 48v 1000w rear hub motor complete kit from eunorau. They originally stated on their website 5 to 7 day shipping that was the main reason I ordered from them and not elsewhere and they also said it was in stock. It took them months to come and honestly have not had the greatest experience with the company but it finally came I took my bike apart put everything together and the motor spins backward inside the hub meaning it doesn’t go anywhere. The display is reading my battery voltage fine even when I did try to throttle it it was reading the wattage that was being sent to the motor. I’m stumped not sure what’s going on. If someone could give me some help or some insight that would be great there’s not really any specialist in my area or at least not that I know of I’m in Brevard County in Florida it’s on the East Coast by Cape Canaveral. Orlando is like the closest big city but it’s an hour away. Help me please. Thanks

That usually means that either there is a "reverse" wire that's been connected (either to ground, or to another jumper wire of the same color), or a reverse switch that's turned on, or a reverse function engaged in the display menus.

If there is a "self learn" wire pair you can connect, then you can follow the kit's procedure for using this function (different for different controllers, but commonly you turn the system off, connect the wire pair, turn it on, wait for the motor to spin the right direction, turn it off, disconnect the pair, then turn it back on and ride).

If there is no reverse and no menu option and no self-learn function (wire or menu), you'd have to change the order of the phase and hall wires until it runs the right direction; it's relatively simple but much more complicated than either of the above, especially if all the wiring is using multipin "waterproof" connectors instead of individual wires each with their own connector.
 
You might post a link to the Eunorau kit you bought. I thought most of them used a molded 9 pin cable to connect the controller to the motor. That eliminates any user errors in connecting the motor.

With the other connect scheme, where the user must connect three heavy phase wires and five thin sensor wires, it is possible to hook them up so the motor spins backwards. I've done it on purpose to understand how it happens.

So tell the forum more about your kit. MAybe a link to what you bought, Is it a molded cable, or is it individual wires. If it is the latter, that can be addressed.

If you look at the manuals page, it looks like the series of controllers are programmable, but didn't see a reverse toggle in the program settings.
