Hi...I posted on the Tongsheng thread but it doesn’t look to have any posts in months. I recently got my bike finished and I’ve got into the “hidden” setup menu to check/change a few of the parameters. It seemed like everything went fine and my test ride went well enough. I went down today and decided to recheck things and I ran into something very strange. All my changes were showing...ie, tire size, mph instead of kph, walking off, etc. I had turned the speed limit off. But... the Sd setting indicating max speed for assist is showing 0000 and although I’ve toggled through all the other settings and they’re all still adjusting fine, this setting doesn’t move when I press the +- buttons...it just stays on 0000. I can’t remember what I set it too...I’d think something like 25mph...but I don’t understand the 0000 on the display. I’ve searched the internet looking for a button press that possibly clears and resets to the factory settings but I haven’t found anything. I’m hoping someone might have a suggestion or two.
