I don't know about the Ride1Up Core-5 model specifically, but the Ride1Up 700 series uses a different display (KD218) and has a menu item called speed limit. It can be set from 11 mph to 28 mph on my revision that I purchased in March. However, this only limits the speed from using throttle only, so pedal assist is not affected by that setting and still assists to around 28 mph per class 3 regs.
