Hi, My E-Vision ebike has a Bafang motor and APT S800 display and three buttons (ON plus minus). All three use UART-Communication.
When double clicking the ON button, I enter a short menu with 7 options. See picture 1.
However, several APT S800-manuals on the internet mention an extended menu with more options, 26 all together. See picture 2.
The ebike is going to fast, the assistance is far to much. So what I want to try, is change one of the extended options : Pas, Range of assistance level setting.

My questions :
  • How can I get into the extended menu?
  • Will replacing the APT S800 display by an APT S800 from AliExpress be a solution?
All help is appreciated !
