Just purchased a Radcity 5 Plus for the wife at the end of June/23. Only put 16 miles on it before the controller stopped sending power to the rear hub with PAS or throttle. Able to get a replacement controller after trouble-shooting and sending iphone movies with Rad Chat. Under a week to arrive and a real PITA to replace. The new controller cables were too long and couldn't secure the two screws for the controller from the outside of the frame (couldn't line up the holes in the tight internal space near the pedals). The new controller worked and back on the road again.
