I recently bought a Stunner LT but my kid somehow got into the menus and changed all the settings. I no longer have pedal assist and the bike will only go about 9 mph with the twist throttle. Can someone that has a stunner LT tell me what their settings are as far as the PO1-P15 (or however high it goes) I looked at the pdf file about adjusting it but im not sure what all of it means HELP!!
