re: History Article of Motorized Bikes
In the december 07 issue of scoot magazine They do a history of the moped. They say Gottfried Daimler built the first working motorized bicycle in 1885. It even had a twist grip throttle. In 1888 the pneumatic tire was created, before that bicycles were known as boneshakers. The london bicycle club showed eight motor bicycles in 1897, over 100 by 1901, and 376 by 1905.
It's a good read.
