I put this into another forum. I don’t see the vibration as an issue.  When I rode the bike 10 miles last evening, the motor cut out, particularly on PAS5 when I was in 8th gear over a distance of several miles.  It then cut out several other occasions.  I was trying to get the backlight to work since it was dark and this may account for the motor cut out.  I received no error message And the battery was at 3 of 4 pips this morning.  I am going to go out on another ride this morning and see whether I can recreate things.
