Well, it started affecting riding, so I sent a message to support:
My problems started at around 20 miles. The problem was a creaking noise. It happened spontaneously and with no reasonable associated cause other than it seemed more likely when weighting/turning on one side of the board.
The sounds were definitely coming from inside the hub.
I read about similar issues and had the exact same symptoms as others on the forum.
I decided to wait as it seemed to be common enough and some were reporting the sound to go away and that it did not seem to affect the performance.
But now I am noting another effect besides sounds at a frequency of the wheel RPM.
The power delivery is no longer smooth. It's as if for 1/8th of the time or so that it's operating under half power.
I feel this while accelerating, while going a constant speed (it can also be heard and felt both at constant speed), and is particularly noticeable when climbing.
The effect makes it harder to balance and it feels unsafe enough that I no longer feel safe riding the board.
So I thought that I would e-mail and see what you guys proposed that I do.
I have been riding about 10 to 20 miles per day for the last few days, and I am enjoying the ride very much, but I hopeful that I can get a board that does not have the issues that this board has.
I have not made any modifications to the board at all, besides removing the cardboard after taking it out of the box and changing the riding mode to Cruz and later to Mission.
I have not tried any other riding modes.
There seem to be no other issues that I am aware of.
If anyone is interested in the outcome, I'll let you know. I am not as confident riding faster as it seems to be omnipresent the problem. At the height, I did look at temps and it said the motor and battery were both under 100 degrees. 98' for one and 89' for the other, but I forgot which was which.
I guess that my thinking is that if it continues to behave this way, I'm just not satisfied with it. I am very hopeful that they aren't ALL this way and this is just NORMAL. That's my worst fear, honestly.
I want more confidence that there is going to be a consistent power delivery that I can expect to be smooth. If they are intentionally cutting power for a brief moment to "scare" me to slow down, it's working, but I don't think that's what they are doing. I think something is wrong.
