The [[Drive Belt|belt]] in wet conditions will often make a pronounced new noise from when it's in dry conditions.
;Variations
: This thread describing a [http://electricmotorcycleforum.com/boards/index.php?topic=5785 loud buzzing sound on acceleration] has audio samples and discussion about how it occurs.
;Description
: This groaning noise has been called many things from a ''Tie fighter'' or a ''Wookie'' to a ''water buffalo''.
;Effects
: It is completely normal and causes no ill effect on the bike, and will go away again when dry.
;Potential Causes
: The belt being dirty while wet may exacerbate this.
:; Encoder Accuracy Hypothesis
:* There is a strong perception that the sound comes from the belt, but also an impression that the encoder sensors inside the motor lose accuracy in high humidity.
:* This would make the controller think the motor is in a slightly different position, then send the wrong/displaced field to the motor, which would result in an oscillation.
:* The motor might be driving the belt to resonate in this case.
;Potential Solutions
* Wait for the bike to dry out.
* Silicone Spray
*: Light application of a silicone spray to the motor shaft to the front sprocket should make it go away for months.
*: {{warning|Ensure the spray doesn't have any petroleum distillates that will eat the belt materials.}}
*: The Encoder Accuracy Hypothesis above implies that one should apply it ''near'' the front sprocket to protect moisture from entering the motor housing.
