The Bi-Autogo, developed between 1908 and 1912, stands as a bold experiment at the crossroads of motorcycle and automobile design. Built by Detroit-based inventor James Scripps Booth, this hybrid cyclecar featured the first V8 engine created by a Detroit company, long before such engines became standard in American automobiles.
Although only one prototype was ever produced, the Bi-Autogo remains a fascinating emblem of early 20th-century innovation.
Key Takeaways
- Built 1908–1912 by James Scripps Booth, the Bi-Autogo had two main wheels and retractable outriggers.
- First Detroit V8, a 6.3L engine with 45 hp, powered the vehicle.
- Cyclecar prototype combining motorcycle and car features.
- Only one made, weighing 3,200 lbs with tandem seating.
- Restored in 2017 by Mobsteel, now held by the Detroit Historical Society.
Origins of the Bi-Autogo
The Bi-Autogo emerged during a period of intense experimentation in personal transportation. In the early 1900s, cyclecars were gaining popularity as lightweight alternatives to full-size cars. Booth, an engineer and artist from a wealthy publishing family, envisioned a two-wheeled motor vehicle with the power and presence of a car, but the maneuverability of a motorcycle.
Construction began in 1908, and after four years of iterative development, the prototype was completed in 1912. Its name—”Bi-Autogo”—reflected its two large driving wheels paired with smaller retractable outrigger wheels, designed to stabilize the vehicle when stationary or moving slowly.
The Visionary Mind Behind Bi-Autogo
Although many groundbreaking inventions have emerged from the automotive world, James Scripps Booth stands out with his extraordinary vision behind the Bi-Autogo.
As a Detroit artist and engineer, Booth crafted this unique cyclecar from 1908 to 1912, revolutionizing automotive design. The Bi-Autogo’s innovative features included a 6.3 L V8 engine, marking the first V8 engine from a Detroit company, delivering 45 horsepower.
During this time, General Motors was also making strides in the automotive industry, having been founded by William C. Durant in 1908, the same year Booth began his work on the Bi-Autogo.
Unique Design and Specifications

The Bi-Autogo Cyclecar dazzles with its unique design and specifications, setting it apart from other early 20th-century vehicles.
Only one Bi-Autogo was ever built, making it a true prototype. Its standout features included:
- Engine: A 6.3-liter (384 cu in) V8 engine delivering 45 horsepower—the first V8 built by a Detroit company.
- Design: Two 37-inch wooden-spoked wheels served as the main support, with two pairs of retractable outriggers for balance at rest.
- Body: Weighing 3,200 pounds, it included tandem seating for three passengers, enclosed bodywork, and a copper tube radiator mounted externally.
- Transmission: A 4-speed manual gearbox powered the rear wheels.
- Unique Appeal: Blending motorcycle posture with car-like features, it defied easy categorization.
Historical Significance in American Automotive Innovation
The Bi-Autogo was never intended for mass production, and its complexity, weight, and experimental form ultimately made it impractical. By the time of its completion in 1912, the cyclecar craze was nearing its end, and lighter, more affordable cars like the Ford Model T were becoming dominant.
James Scripps Booth redirected his attention to more viable designs, founding his namesake company in 1913, which introduced compact, stylish cars that were far more commercially successful.
The Federal-Aid Highway Act of 1921 played a significant role in the development of American road infrastructure, paving the way for innovative vehicles like the Bi-Autogo to be driven on modern roads.
Preserving the Legacy of Bi-Autogo
Although the Bi-Autogo never went into production, it left a lasting legacy in three important ways:
- Engineering Firsts: It introduced Detroit’s first V8 engine, predating broader V8 adoption by major automakers.
- Design Exploration: Its unique configuration inspired conversations around vehicle stability and hybrid formats.
- Historical Preservation: After decades of obscurity, the Bi-Autogo was restored in 2017 by Mobsteel and is now housed by the Detroit Historical Society. As a one-of-a-kind artifact, it highlights the bold, creative spirit that fueled the early years of American automotive invention.
