I can't say I always get appropriate answers to my questions. However, I always get prompt courteous service with very quick attention to orders and delivery. I have purchased 3 wheels in the past year and a half, a Gotway Tesla V2, an Inmotion V11, and a Begode RS-19 HT. I enjoy each for their unique characteristics and strengths. I cannot say I've had any serious service issues with any of my wheels to date. However, my riding style is quite conservative and I tend to avoid extreme conditions and weather, yet I have used them occasionally in winter conditions and temperatures down to 20 degreed Fahrenheit. I think the Tesla V2 is an excellent starter wheel with a great deal of power and utility to last many years as a light, agile, commuter. The RS-19 HT is a very smooth ride with a great deal of power, strength, and agility for hills and off-roading. My V11 is a very comfortable and forgiving cruiser. There is little to complain about. I do feel that eWheels is lacking in timely, critical, and useful consumer information on the products they sell both generally and in detail. For instance, the factory recommended pressure settings for the air springs in the V11 suspension system are all wrong. My background is as an engineer in product development and manufacture. Starting pressures (psi) in the lower chamber should be around 1/2 the riders weight in pounds and then adjusted up or down to provide a comfortable ride in the 30 to 50 millimeter range of suspension displacement from the bottom of travel according to typical terrain conditions while riding. The top chamber can then be charged with 50 to 70 psi for stiffness and dampening of rebound in the suspension system. This method greatly improves overall ride quality and stability on a variety of surfaces and road conditions for the average user. Finally, eWheels could really use an up to date and consistently maintained User's Tips Page and timely EV FAQs on their website.
