I bought a GRANDTAN TURBO Trike online from Addmotor. I had only ridden it twice and had 11 miles on it. Then I had to undergo cancer treatment and didn’t get to ride it for a while. When I did go back to ride it, it would not go. I contacted Addmotor and they said it was one month out of warranty and would do nothing for me. So I took it to an authorized dealer and repair service center. They checked it out and said that everything that is wrong with it is Addmotor defect. The dealer contacted Addmotor and they would do nothing to resolve the situation. I’m totally disgusted. I paid over $3500 for this trike and it won’t work. Addmotor sent me a defective trike and will not stand behind it. Their customer service sucks. Whatever you do, do not buy from Addmotor online.
