The Bi-Autogo was a prototype American cyclecar, built from 1908 to 1912. Designed and built by Detroit artist & engineer James Scripps Booth, it had the usual two wheels (wooden-spoked, 37 in), plus two pairs of smaller, retractable outrigger wheels in the three-seater body. Fitted with wheel steering, it had a 45 hp (33.5 kW) V8 engine (3.5 x, 384.8 cuin), the first of its kind from a Detroit company, with an external copper tube radiator, and a weight of 3200 lb. Just one was built. It is in the collection of the Detroit Historical Society. The Bi-Autogo was restored in 2017 by Mobsteel in Detroit.
