Stock Photo - 1968 - Introducing the new Winn City Bike.: The Winn City Bike - an all - electric two- wheeler was introduced yesterday at the Elephant Castle, when it was officially launched. It is simplicity itself to operate , highly maneuverable and easy to park. it is quite surprisingly robust and compact (only 42' x 9 1/2 ' x 30' including full extended handlebars). No noise, fumes, starting troubles, patrol, gears or maintenance - simple switch on and drive off. it will travel up to twenty miles on one charge, and all in the mains overnight. And it has a top speed of 25 m.p.h. Among the suggestions for the use of the Winn City Bike are: Conveyance of commuters from home to public transport; Messenger service and errand running, aerodrome and race tracks where marshals have to travel large distances quickly and easily, etc. Photo shows 24-year old Judith Crawford demonstrates how easy it is to ride up an escalator, on a Winn City Bike.
