A few of the wires leading into the motor of my RADWAGOn 4 are broken right where they enter the axle of the hub. Purchased a used and abused RADWAGON 4 and would like to repair this. BAFANG MOTOR. Replacement motors are not available from RAD as you probably know since they went into receivership. I am willing to try and resolder the broken wires and looking on advise on how to gain access to them. Second option is to find another motor I can drop in without having to cut the  big proprietary 9 pin connector that is connected to the hub motor.
