Purchased a demo unit. When the unit arrived, I checked it over and found that the rear light did not work; as a tail light or a brake light. I contacted support and they sent me a tail light module with no instructions. Contacted support again and they said they did not have a video for this repair. I spent some time looking over the scooter including loosening the back fender and removing the tail light lens cover but could not determine how to access the wire connector. I did not want to dissamble further so I reinstalled the lens and fender. Looks like I will do without a rear tail light/brake light. Also, the scooter was beat up more than I expected with numerous dings/dents/chipped paint along the sides of the standing platform. On the positive side, the scooter appears to be sturdy, the controls are easy to understand, and the scooter is fun to ride. Max speed is close to what was claimed (would not want to go faster on a scooter). Have not checked the miles/charge yet.
