Three lamps in mistake flashing.
The battery is not charged, throttle does not work.
I already also disconnect battery from the controller and connected
What only did not make any more (
I so understand it battery problem?
or controller?
Or what the mistake is?

I write on Optibike and to Optibike service
no who answers ((

Optibike 850R has bought in 2012

Thanks
Sergiy
