Billing yourself as the biggest eBike maker in the US isn't really saying much...most of the parts are from Asia, as with many other bikes. Many traditional brands probably sell as many or more eBikes in the US, they just don't classify them as being made in the US.
That being said, this is a great concept. I wouldn't compare this to a bike, it seems like competition to small gas scooters like the Honda Metropolitan, and compared to those it's quiet, probably a lot more reliable and things like being a single speed or seat positioning are irrelevant since no one is going to be using the pedals to propel it. The only thing that's lacking is a higher top speed - this will probably be ridden in urban areas a lot and near a lot of car traffic. 30 mph allows you to keep up with urban traffic, 20 mph not so much.
It's great to see choices in the marketplace. Light ebikes with a bit of assist that are light and retain the feel of a traditional bike; traditional ebikes that are somewhat like bikes but are heavy and provide most of the power for people with health problems or who don't want a workout, and now bikes like this that are a viable means of transportation in some areas for those who don't want a bike but just need a way of getting to places without using a car. I could easily see having multiple ebikes for different uses.
