I found a problem with a tandem which I had converted with a Luna mid drive on Thursday afternoon. Not knowing the immediate fix, I ordered a motor/controller the next day. I am located in Florida and knowing that the tandem couple needed a quick fix [they are training for Coast to Coast], I made contact will Kelly at Luna to try and get a quick delivery of the needed part. She responded by doing all she could to get my order packaged and ready for shipment but could not promise when the shipper would make the pickup. As luck and excellent service from Luna would have it...it was picked up by the shipper on Friday. As I tracked the package over the weekend and the MLK holiday, it was scheduled to be delivered on Wednesday afternoon. Much to my surprise it was delivered this afternoon [Tuesday] at 3 pm. This was one day earlier than expected. I could not be happier with the attention that Luna and their order/shipping department extended in getting this critical part to me...and the tandem couple is elated with the service from Luna to our mid Florida town. This is the 5th tandem that I have finished for teams in the area and the first problem. Now that thing have settled down, I can locate the problem in the original motor. A great big Thank You to Luna and their staff.
