Surely if the crank is turning then it must be a problem with the cassette?
I had this on my new metapower SX (crank, chain and cassette all turned, but no drive), bike shop took the cassette off, cleaned, re-greased and its been fine ever since.
Are you charging on the bike via the port, or removing the battery and then charging it?Not sure this makes any difference to the switch.... I’ve only charge the battery off the bike. I’ll give it another go tomorrow.
Any joy with yours?
I’ve just been out for a ride, and after 40 min the switch still won’t work. Commencal said it could be the cold weather.... and they are in discussions with Shimano as there are others with the same problem.
