thanks Alan, I was hoping they used manganese and not colbolt , polymer etc. Even so I thought they may have been a mix of different substances
BTW, Monday is now looking likely to be the Launch day
. I had taken my bike to an E-bike retailer/ electrical engineer to have things fully sorted. He's had special washers made to help hold the axles in place in what have turned out to be very shallow rear dropouts. I have not seen the washers yet so will be interesting. Can't wait to write up an article about the whole thing.
