I am approaching 11,000 kilometers /!!!/ on my 1000W EPLUS.
I am going to report soon when I reach that millage with pictures.
No any mechanical or electrical problems, couple of glitches on power ups, maybe 2 a year, beside that EPLUS drive works flawlessly.
Bicycle parts replacements I did are not related to EPLUS electric drive.
Due to EPLUS regen disc brake pads seems to last for ever on my Biria.
