First, some historical context: The vehicle I was designing—call it EUV, for "electric utility vehicle"—was a low-speed urban utility vehicle, similar to the Westward GO-4. You're probably familiar with the gas-powered GO-4. In fact, a GO-4-driving parking enforcement officer has probably ticketed you in some major American city. These are certainly not motorcycles, but they are motorcycles in their DNA. The GO-4 is a modern response to Harley-Davidson's three-wheeled Servi-Car utility vehicle, an extremely popular and practical service vehicle produced by The Motor Company from 1932–'73 and still used by some police departments as recently as the mid-'90s.
