I purchased the Hyper-Scorpion model and received it on 9/9/20. It worked fine for 11 days then experienced issues. Initially I was able to make contact with their Tec Support department. Twice they supplied suggestions to fix that did not work. They then involved a supervisor whom I spoke to that promised me a replacement part, a controller would be shipped under normal circumstances the next morning. I agreed. She was to contact me the next morning with the shipping info so I could track the replacement item. That was on 9/22/20 at 9:19am and we spoke for 14 minutes. Since that last contact I have called their support number 9 times daily and sent emails nearly everyday asking for some contact and support. Finally after threatening to post a complaint on the BBB on October 1st, 10 days after my last contact with the supervisor I get an email saying to be patient and I will get a replacement part when they are available. Today is October 7th, a week later. I continue to call 9 times a day and email daily with no responses even though their message promises a contact back within 1-2 business days.. I've even offered to drive the 264 mile round trip so I could bring them the bike directly. They refused the offer. I think a company should respond to customer inquiries especially when the product is unusable after 11 days. Additionally since they promise it within their communication. My $3K new bike has less than 60 miles on it. I could not be more dissatisfied with this companies customer service. Reporting them to the BBB.
