Source-linkedVerify source — Reddit post

Reddit post by u/Odd_Condition_2772 (r/ebikes). QLife Spark e-bike power button failed—first required holding the button to ride, then would not turn on at all. Photos show rust/corrosion on the switch board. A replacement S866 display with integrated buttons would not communicate with the controller (error), leaving the bike unusable.
