The E-GO is far from a cheap knock off. It comes from Yuneec.com who make real electric aircraft and are experts in Electric Propulsion Systems. It is our ability to do mass production which has brought the price down. The design and testing was done by an international team in including several ex-pat Europeans and American employees of Yuneec. We make most of the components in the E-GO and our own motors have a 15 year development history. We also now use auto short circuit protection Panasonic batteries, the best and most expensive in the industry, just like Tesla does.
