My bike (eZeebike iOmega) has been working really well but lately there is an interesting issue. Every once-in-awhile, the motor just stops working. Nothing I do (peddling or activating the throttle) helps, but after a couple of minutes it starts working again. The cycleanalyst shows good voltage and the indicator shows the throttle is being activated, but the motor doesn't operate. Today I noticed something that is probably diagnostic. There is a red LED on the controller that is solidly on when the bike is powered on and working. When the problem occurs, the LED blinks on five times, pauses, blinks five times again, pauses, etc. When the problem goes away, the light is solid again. Does anyone have a clue what the five blinks indicates?
