My 2015 Stromer has started switching power assist off occasionally recently. Always from a stop. I thought I had solved issue by correctly torqueing hub to 20 nm. Previously I had removed the battery and replaced it , and power had reset and bike ran fine again. Another clue to power cutoff has something to do with the brakes. Because one time I abruptly tapped both quickly and power came back on. Everything was fine for awhile since retorquing hub, but had to use the tapping brakes remedy which worked once again yesterday . Any ideas what could be causing this ?
Thanks in advance for any help
