Title: Is my motor bad ?
Post by: Plynch2 on August 22, 2012, 10:52:51 AM

2011 zero S 1900 mi I was riding around 45 mph and I tried to accelerate twisting the throttle wide open the bike jest stayed  at 45mph and there is a arcing noise coming from the motor. Now the bike won't go over 30mph. Do I have bad brushes? And I only get about 30mi on a charge.

Brushes would be the place to start. How close is your dealer and is it still under warranty?

Bad brushes or misaligned , loose. Contact dealer/Zero for advise.

Does the motor growl or grind louder ?

With my 2010 we swapped motor and it turned out to be the BMS instead.
