OK, so after the test drive, the bike works fine, except for the lights issue.
I was surprised, like others, that it seems to work on an all or nothing basis until 25km/h and with very subtle (if any) difference between the 1-5 assist modes. But I guess this is an issue of the type of assist rather than a defect.
@satyasekhar Did unplugging (after cutting the ties) and plugging back solve your problem?
@gol. Yes it did resolve the problem. Now I can see that my speedometer started working. Thanks a lot @gol and @cjm1066 . I didn’t cut the ties, I just unplugged and plugged it again 🙂
But the battery power percentage on the display is still not accurate.
By the way, AMX bikes are pedelecs so I believe it doesn’t matter whether the assist level is at level 1 or at level 5. Rider has to apply strength then the bike will catch 25 kms even at level 1 and being on level 5 requires less strength from a rider.
