Try starting from a Walmart BSO with the cheapest V-brakes Shimano makes, throwing on a Chinese gas engine kit, adding a milk crate based rack system, and riding your new sub-$200 semi-legal DUI-mobile down the road at 50mph.
I see one riding (on the sidewalk) once in a while here, no idea how he survives.
