Go-Go mopeds were manufactured from 1970 (possibly earlier) to 1977 or later. They are sometimes listed with dates in the eighties, but these are currently unverified.
The Batavus Go-Go VA was exported to the US 1976-77 but was available in Europe some years earlier. Aside from the stainless steel guards it looked very much like the Batavus Bingo.
The VA model was preceded by the rigid-frame Go-Go V. The V30 model was sold in Germany and elsewhere.
