I am pretty sure my friend Randy said he sold some pedal revolutions back in the late 90s early aughts. That and my friend Chad reported seeing one parked at one of the university buildings. Not moving, parked.
Maybe not, but thats word on the streets, that there are a few running around Madison area.
My engine says start V, but I don't think it has electric start.
I am pretty sure the start engine is a series, like AV, not a description thereof.
As far as the hunter/manhattan having swappable parts, I am pretty sure there is a scooter derbi called the revolution.
I am not sure how much if any the scooter revolution shared with the cool revolution, but its something to be aware of when looking for interchangable parts.
