I love my local museum, the Owls Head Transportation Museum! There I've seen in person, the only existing
1913 Scripps Booth Bi-Autogo. (Larger image attached below...)
The Wiki entry is PC, just the facts:
Designed and built by Detroit artist & engineer James Scripps Booth, it had the usual two wheels (37 in. {94 cm}, spoked wooden ones), plus two pairs of smaller, retractable outrigger wheels (an idea that has resurfaced since) in the three-seater body. Fitted with wheel steering, it had a 45 hp (33.5 kW) V8 engine (3.5"x5", 384.8in3, 6.3Li), the first of its kind from a Detroit company, with an external copper tube radiator, and a weight of 3,200-lb (1451 kg). Just one was built. it is in the collection of the Detroit Historical Society.

A 3,200-lb. motorcycle with training wheels, a V8 engine and enough copper tubing to provide every hillbilly in the Ozarks with a still, the Scripps-Booth Bi-Autogo was the daft experiment of James Scripps-Booth, an heir of the Scripps publishing fortune and a self-taught — or untaught — auto engineer. The Bi-Autogo was essentially a two-wheeled vehicle, carrying its considerable heft on 37-in. wooden wheels. At slow speeds, the driver could lower small wheels on outriggers to stabilize the vehicle so it wouldn't plop over. This is not a case of the advantage of hindsight; this was obviously a crazy idea, even in 1913. The Bi-Autogo does enjoy the historical distinction of being the first V8-powered vehicle ever built in Detroit, so you could argue it is the beginning of an even greater folly.
