About Janus

Country of Origin: United States
Founder: Richard Worsham & Devin Biek
Best Known For: Hand-built, small-displacement classics (Halcyon, Gryffin) made in Indiana

Company History

Janus builds jewel-like motorcycles in small numbers, emphasizing craft, proportion, and simplicity. Frames are hand-welded in Indiana; tanks and fenders are formed locally; engines are proven, serviceable singles chosen for character rather than peak output. The Halcyon, with its hardtail look and leaf-spring fork, channels pre-war aesthetics; the Gryffin leans scrambler. Each bike is specced with the buyer—paint, leather, racks—making ownership feel like commissioning a piece of functional art. On the road, Janus machines reward pacing and scenery: 55–65 mph on two-lanes, engine and road speaking clearly through the bars. The company’s transparency—build photos, local suppliers, and straightforward service docs—has earned goodwill in a market dominated by scale. Historically, Janus keeps alive a human-scale ideal: motorcycles as hand-crafted instruments rather than mass-market appliances. For riders who value presence over numbers, a Janus is a reminder that romance and reliability can meet in one meticulously assembled machine.
