Liberty Motors (United States) - AllCarIndex

Liberty Motors was a small American builder of motorcycle-derived three-wheelers and sidecars based in Seattle, Washington. Operated by fabricator and designer Pete Larsen with his wife, Patty Billings, the company produced Harley-Davidson–compatible Liberty Sidecars and later developed the ACE cycle-car. The ACE, conceived in the early 2000s and first driven in 2005, adopted the classic front-engine, two-wheels-ahead Morgan layout but used a modern Harley-Davidson Twin Cam V-twin on a TIG-welded spaceframe with rack-and-pinion steering and shaft-driven single rear wheel. Limited, built-to-order production followed. Around 2010–2011 Larsen sold the ACE design to Morgan Motor Company, which used it as the basis for the revived Morgan 3-Wheeler; Liberty ceased building the original ACE thereafter. Liberty Sidecars, the firm’s long-running sidecar line, closed at the end of the 2010s.

Larsen later returned to the concept with a second-generation ACE developed in the late 2010s/early 2020s, this time a mid-engine “reverse-trike” using Honda Gold Wing flat-six running gear. The business remained independent, produced in very small numbers.
