fat tire trader ... i agree with you ... a "big boom year" of notoriety would hardly celebrate a modification
to the diamond-frame bicycle .. creating a "bulldog" or "motorbike" by adding and/or bending a unit of frame
tubing. The (article-stated) "big boom year" certainly makes a reference to a time much earlier than 1914 ...
TOC or earlier ...... but i can't venture a ghost of a guess on any particular year.
Maybe i'm overstating the significance of the 'motorbike' design ... just 'cause i likes it !!! That "big boom year"
may simply refer to a year of bicycle production with respect to 'numbers' made ... celebrating at "The Altar of Quantity".
Ya it was flooded, lots of used bikes and NOS bikes from previous years were offered in ads of '98. It could be '98, I'm just thinking after the economy went south in '96 there was likely a downturn of production and lots of overstock.
Or bought out by colonel Pope and the ABC... then shut down by Pope so he could eliminate his competition and sell the manufacturing equipment. He really picked a bad time to start a monopoly. The 90's was the beginning of the assembled bicycle and the end of the armory style that came before it. That's when there were hundreds of bicycle manufacturers. They used companies like Aurora Automatic Machinery for their lugs and Shelby tubing for the frames. The armory style of building needed huge facilities and massive machining capabilities. Western Wheel Works showed that stamped metal parts could be used at a fraction of the cost of castings or lath produced parts. Iver Johnson was one of the only companies that survived by producing everything in house. Even Westfield Mfg called itself an assembler of bikes in the late teens when they were testifying in front of congress in regards to tariffs.
