About Arch

Country of Origin: United States
Founder: Keanu Reeves & Gard Hollinger
Best Known For: Ultra-premium American performance cruisers with bespoke ergonomics

Company History

Arch Motorcycle was born from actor-rider Keanu Reeves’ request for a custom bike and builder Gard Hollinger’s refusal to compromise on execution. Their collaboration evolved into a boutique OEM crafting hand-finished performance cruisers that fuse American V-twin charisma with sportbike-grade components. Each Arch is built to order: owners are measured for contact points, consulted on finishes, and invited into a process more like commissioning a tailored suit than buying a motorcycle. Billet-intensive frames and swingarms, carbon bodywork, and top-spec suspension/brakes deliver stability and precision at elevated speeds, while the big twin supplies linear shove and a rich mechanical soundtrack. Electronics remain purposeful rather than flashy; the focus is analog connection filtered through exquisite hardware. The brand’s ethos—craft, fit, and ride quality over volume—positions Arch in a rarefied niche alongside the finest small-run makers. Historically, Arch reimagines the American performance cruiser as a design object with genuine dynamics: long-distance comfort, fast-road capability, and componentry chosen for lifetime service. It also proves that celebrity involvement can be substantive when paired with a disciplined engineering partner. For owners, the value is partly metal and partly relationship: a motorcycle that reflects their body and taste, built by people they can call by name.
