It uses the Bafang CAN protocol over a triangle connector and is NOT compatible with UART BBS displays. IPX6. Crank interface is a Bafang proprietary spline (NOT ISIS) on a 104 BCD 4-bolt spider accepting 32–40T chainrings; it requires a purpose-built frame with motor mounting tabs and is not retrofittable to a standard BB-shell bike.
