My first E8000 motor did 21,308km my second motor has done 14,450km and is very noisy in Boost mode when on a climb. It has started turning off completely without showing an error code. The bike is a Merida eOne Twenty500. I've had two new motors on order since early September. ETA was November...
I've just had the motor replaced on my Merida eOne Twenty 500. It had done 21,308km at the time of replacement. 80% of my riding is commuting on road. With the other 20% off road, dirt trails and gravel roads. It was only making a grinding noise under load but was fine on the flat.
