Hi everybody. I will show being brand new here because it's been years since I've returned or posted here. My Easy Motion E-bike has worked flawlessly for me for 7 years. Recently, the display has started turning off when I am under heavy load. I can pretty much trigger it to turn off by going up a steep hill on a higher assist setting like Boost or the one below that. As best I can tell, it never turns off on level ground. No one is supporting these bikes in my city anymore. Anyone have any ideas what's going on, or how to trouble shoot? Thanks in advance.
