The bike does turn power on.
After power on, both mission control or blevo, cannot detect the presence of the new motor. The new motor won't give any assist.
I just know this now, do we did to link them together? "dealer software to link the motor, battery and TCU together" and "the battery has the motor serial linked"
Another friend of mine had replaced with new internal battery on his bike - it was just plug and play. Did not involve any programming.
