Ok just checked the advanced menu and found the issue in that the speed limit setting was down to 20. No idea how that changed as never been into that before. Ramped up to 40 and wife all happy again. Now I need to do mine so I can keep up. Wondering if it's a sign the controller is acting up. If so I see an upgrade in the future. Thanks

Rad Rover 5, US. Had 13 months so all stock. Did replace original controller due to short for brake lights, replaced with OEM from RAD under warranty. All was working well last week, jut started and not changes made.

have searched and can't find anything like this. Went for morning ride with wife and about half way thru I look back and she's fallen way behind even when trying to catch up using throttle or higher level PAS. seems she is limited to 12.5 mph, unless totally self powered herself. In testing it I can see where it will take off like normal and seem to go, but then it slows itself down maxing out at 12.5 almost like it hits a governor. Any ideas? Had about 18 month and no issues except initially had to replace the digital display and wiring as the motor stopped completely engaging.  Thanks in advance.
