Functioning on the principle of an eccentric rear wheel, the latest bicycle has neither gears nor a chain. Invented by Phil Huyseng of Chicago, the bike is propelled by a bouncing motion of the body.
But wait, there’s more!
Here’s one from “New Ideas for Living” (above) – the site says it was invented by Ingersoll-Rand in the 1930′s (below the red bike).
I looked to see if “Phil Huyseng” was a patent holder, or google-able at all — nothing. But I did try some similar spellings and found this, the Whymcycle…
An Ingo-bike is a vehicle similar to a kick scooter, with a large rear wheel. Invented in 1934 by the Huyssen brothers and called the “Exercycle”, then produced by Ingersoll-Rand Corporation from 1934-1937, under the name “Ingo-bike”. A group of Ingo-bikers in the late 1930s traveled from Chicago to Miami in 30 days. Re-introduced as a children’s scooter in the 1960s with the name “kangaroo scooter”. And finally, produced since the 1990s and called “whymcycle”, by inventor/substitute teacher Peter Wagner.
A team of Ingo-Bike riders made an incredible trek from Chicago to Miami, FL on the odd machines in just over 30 days.
