Roadog

William "Wild Bill" Gelbke, was an electrical engineer who was employed by McDonell-Douglas to work on the defence system but who had aspirations to produce his own motorcycles. In 1962, Bill decided to pursue his dreams, quit his job to open a motorcycle shop,  and went to work on designing and building "ROADOG".  

Apparently, and as the photos may back up, the motorcycle was over 5m long (17') and weighed in at a mere 1488 kg (3280 lbs). Not hard to believe, since it boasted a 4 cyclinder 152 cu.in 'Chevy ll' engine, a 'Powerglide' transmission and had a modified Chevy differential, along with a Corvette's disc brakes. Since a kickstand would have been useless, it employed 4 hydraulic rams to keep it upright when parked. 

Bill also worked on a 'smaller' bike, which was dubbed the 'Auto-Four' and only had an Austin Mini motor and transmission. Apparently he produced and sold about 8 of them in the years between 1965 and 1979.

Bill's idea was to produce a bike that was capable of cruising at high speeds for long distances, certainly possible with this beast that could maintain 150 kmph all day long. Of course, looking at the bike, I wonder about the practicality of such a large, heavy machine and it's handling. Not everyone's dream ride but certainly interesting and ambitious.

"Wild Bill" inevitably lived up to his name and got into a domestic dispute that brought the police, who shot him dead when he threatened them with his gun. Buzz Walneck, of Walneck Swap fame, eventually found and bought the bike and now has it on display in his showroom in Chicago.
