In 1903, in a modest 10x15-foot wooden shed in Milwaukee, Wisconsin, four young men embarked on a journey that would forever change the face of motorcycling. William S. Harley, Arthur Davidson, and later joined by Arthur's brothers, Walter Davidson and William A. Davidson, laid the foundation for what would become one of the most iconic motorcycle brands in history: Harley-Davidson.

The Early Vision

William S. Harley, just 21 years old at the time, had a vision to create a motorized bicycle. Collaborating with his childhood friend Arthur Davidson, the duo set out to design and build a machine that would make transportation faster and more efficient.

• The First Design (1901): Harley created blueprints for a small engine designed to fit onto a regular pedal bicycle. However, the initial prototype lacked the power needed for challenging terrains.

• The Shed: The team began their work in a tiny backyard shed, affectionately referred to as the "factory." It bore a simple sign that read "Harley-Davidson Motor Company."

The First Harley-Davidson Motorcycle

By 1903, Harley and Davidson had completed their first motorized prototype. The key innovations included:

• An Engine: A 116cc single-cylinder engine, though modest, provided enough power for practical use.

• A Unique Frame: They built a frame specifically designed to house the motor, moving beyond the standard bicycle designs of the era.

This creation marked the beginning of Harley-Davidson as a brand that would combine functionality with durability.

Joining Forces with the Davidson Brothers

Recognizing the potential of their invention, Arthur enlisted the help of his brothers, Walter and William Davidson. Together, they refined the design and focused on:

• Improved Power: Upgrading the engine to a 405cc single-cylinder model.

• Durability: Crafting a sturdy frame that could withstand long rides and rough roads.

By 1904, they had created their first production model, marking the official entry of Harley-Davidson into the motorcycle market.

The First Sale

In 1905, the company sold its first motorcycle to a local enthusiast, cementing its reputation for producing reliable machines. The year also marked Harley-Davidson's debut in a motorcycle race, an important marketing move that showcased the performance of their bikes.

Rapid Growth

• 1906: Harley-Davidson built its first factory on Chestnut Street (later renamed Juneau Avenue), which remains the company's headquarters today.

• 1907: The company was officially incorporated, and production expanded to 150 motorcycles annually.

Legacy of the Shed

The humble shed where Harley-Davidson was founded represents more than just the beginning of a company—it symbolizes the ingenuity, determination, and collaboration that are hallmarks of the American spirit. From those early days, the brand has grown into a global icon, but its origin in a small Milwaukee shed remains a powerful reminder of how big dreams can emerge from the smallest of places.
