Excelsior Motor Manufacturing & Supply Company

The Great Depression convinced Schwinn to order Excelsior's operations to cease in September 1931.

Colors were grey with red panels in the early teens, the 'Military Model' of the late teens was in khaki (a green-brown shade) and 1920s models were in a very dark blue with fine gold pinstriping.

A very small number of BigX motorcycles were manufactured with 74 cu in (1,210 cc) engines in the 1920s.

[5] In response to the Super X's popularity, Indian first raised the Scout's capacity to 45 cubic inches (737 cc) and then introduced the new Indian 101 Scout,[6] while Harley-Davidson introduced their 45 cu in (737 cc) motorcycle, the Model D. In 1929, the stock market crash and the resulting Great Depression caused motorcycle sales to plummet.

The summer of 1931 saw Schwinn call his department heads together for a meeting at Excelsior.
