I am a history nut and a motorcycle nut so I should know this stuff.
“The Streamline was fast – capable of a genuine 100 mph (160 km/h), and advanced for its time, with such features as leading-link forks and an illuminated speedometer built into the fuel tank.
The Streamline model was produced from 1929 until 1931, and sold for $435”
Here is the Streamline. Wild for it’s time in 1929.

I wish I had the opportunity to ride one of these old time cycles. What a thrill!!
