I used this website to gain a little knowledge about the first true motorcycle. It provided me with pictures, and information on the motorcycle I had never heard of for example when he stated; "The Rietwagen was built out of a wooden frame and came complete with stiff, unforgiving wooden wheels. Needless to say, the bike was not exactly a comfortable way to cruise around town. Though the Rietwagen is widely accepted as the first gas powered motorcycle ever built, some controversy surrounds this claim because of the bike’s two training-wheel like supports on the back."
