Ace was the creation of Scottish-born engineer William Henderson. He was an advocate of using four-cylinder engines in motorcycles. Ace achievements included Charles ‘Red’ Wolverton’s 129mph motorcycle speed record and 106mph sidecar record of 1923. Ace motorcycles were a popular choice with American Police forces.

William Henderson began making four-cylinder motorcycles under his own name in Detroit in 1912. He sold out to Schwinn in 1917. Henderson started Ace in 1920, designing a lighter and entirely new four-cylinder machine, avoiding patent infringements with Schwinn. Henderson was killed in a road accident in December 1922. Ace was absorbed by Indian in 1927, the four-cylinder machines becoming known as the Indian 4.
