There is no one theme to Norman Hobday's collection but the man does seem to have had a soft spot for motorized bicycles. One of the rarest of these is the Monark Super-Twin, made by the Monark Silver King Co. of Chicago, which in the 1930s began selling an innovative aluminum-framed, balloon-tired bicycle. Seeing Whizzer's success with powered bicycles, in 1949 Monark cataloged its own purpose-built machine with a more conventional steel frame. Providing the pedal-assist was a unique opposed twin-cylinder two-stroke engine, liberated from lawnmower and chainsaw duty, good for 2 horsepower. The bikes were always sold in two-tone paint schemes, and this turquoise-and-creme Super-Twin is further set off with chromed belt guard, centerstand and front suspension spring/strut.
