I stumbled across this forum while researching a Simplex Service Cycle for a friend. I've always been very fond of motorcycling's humble and home spun beginnings as motorized bicycles and currently own several excellent motor prospects including '39 & '61 Hawthornes, and a '56 J.C. Higgins(great bikes in nice "survivor" condition) . I have, of course, seen Whizzers and have thought that converting one of my bikes would be a fun project for my cluttered and seldom restful mind. Nothing can focus me like a project like this. Just thinking of all the fantastic variations I've found here keeps me entertained for hours!! Many Thanks to all of you who help "feed my follies".
