There is a rumor among the USA scooter/moped culture that an electric three-wheeled moped was produced around 1979 or 1980 in Israel/
Rumor has it that it was based on the American Microcar or American Tri-Ped or Tri-Ped USA petrol model of the same year vintage.
Stuart Pivar of New York was the inventor of all three of these mopeds and there are several patents attributed to him Google Patents (one specifically for an electric version).
I found one reference about this electric moped in the American media in which Mr. Pivar referred to it as the model E-1 (or E1). One other Australian reference also tells about the supposed electric Israeli version: http://customers.skymesh.net.au/~fdiwel ... 0Cover.pdf
