Oscar Hedstrom had mounted a single-cylinder De Dion engine on a tandem bicycle for the purpose of pacing then-popular bicycle races.
George Hendee, a bicycle manufacturer from Springfield, Massachusetts, saw the contraption at an event and proposed a cooperative effort to produce motorized bicycles commercially.
Hedstrom agreed, and in 1901 the Indian Motorcycle Company was born. Most pre-1910 motorcycles look as though the manufacturer simply bolted an engine and its accessories onto a common bicycle frame -- which indeed was usually the case.
But early Indians used the engine as a stressed frame member, effectively replacing the downtube beneath the seat.
As with most motorcycles of the era, suspension was non- existent (save for the spring-mounted seat), and pedals were used to start the engine.
However, Indian used a direct-drive chain rather than the more common tensioned leather belt to turn the rear wheel, the chain being more positive in operation -- and more reliable.
This 1904 'humpback' is little different than the first 1901 models. Producing just over two horsepower, the 13-cubic-inch single provided a top speed of around 25 mph.
Both the lubrication and ignition system were of the 'total loss' variety. Braking was accomplished by backpedaling, which activated a rear coaster brake.
Dark blue was the color of choice until 1904, when black and vermillion became optional. The vermillion would later be known as 'Indian Red.'
