If that's a Bafang hub and RKS hasn't changed the code for advanced settings you could try '1919' or '1199'. If the controller is locked you'd need to replace it to bypass the assist limits. I wouldn't want to be caught on an illegally modified bike in the event of an accident, though.

It depends on which display you have, but the menu is usually accessed by double-clicking the power switch when the display is on, then navigating to the 'advanced' settings which prompts for the PIN.
