Attempted to refund within 15 days and woman on the phone would not give instructions on how to do so. I sent emails, made phonecalls, and was never responded to. The Bike arrived non functional and damaged. Customer service and the company phone line only responded after the 15 day warranty and then requested that I fix the bike myself with complicated wiring instructions. This company should be sued and brought to justice by the government... this problem will only get worse because they are selling scooters to unwary internet buyers. The case against this company is easy to prosecute because there are so many complaints and the company has such a consistent pattern of not honoring their warranty and shipping faulty products. The battery and the throttle on these bikes is totally unreliable and often is defective and with the number of complaints www.x-tremescooters.com has the company is well aware of the flaws with their product.
