Hi Spicy, there were never any versions of New Edition Whizzers that had kick starters. The Original Whizzers with kick-starters were only 2 models, the 20 inch Sportsman, and the 24 inch Ambassador.
The kick starter had a special flywheel, in addition to the foot-lever.
This is not to say that no-one ever did one for themselves, but I have not seen one.
I kick-start ALL my Whizzers, up on the stand, with the pedals.
Mike
