American Custom Bicycles in Steel, Titanium and Ti/carbon mix

History and Milestones


Seven Cycles was incorporated in January 1997 and shipped its first bicycle frame in early April of the same year. The company was initially based in Topsfield, Mass., then moved to its current location in Watertown, Mass. in February of 1998. Founder and president Rob Vandermark and the Seven team have been working with titanium since its introduction into the cycling industry, pioneering many of the design and manufacturing techniques used throughout the industry today.

Physical Plant

Seven operates in 15,000 square feet of industrial space in Watertown, Mass. Approximately 9,000 square feet are dedicated to manufacturing, 4,000 square feet to office space, and the remainder to a break room, lockers, commuter bike parking, and a meeting area.


Seven Cycles manufactures high-end bicycle frames from butted and straight-gauge domestically-sourced seamless 3-2.5 titanium, filament-wound carbon fiber, and the world’s finest steels. Seven offers a wide variety of frame styles—road, touring, triathlon, criterium, track, cyclocross, mountain, suspension, and tandems—in the customer’s choice of stock or custom geometry. The company also manufactures a custom titanium stem and mountain bike handlebar, and offers an exclusive carbon fiber road fork, as well aluminum handlebars, stems, and seat posts. All of Seven’s frames come with a lifetime warranty against defects in manufacturing and materials.

Sales Channels

In the United States, Seven sells its frames through authorized Seven retailers—typically independent bicycle retailers with the capability to serve high-end clientele.

Seven currently works with nearly 200 authorized retailers in the United States, with California, New York, and Boston as the strongest markets. Seven is also represented internationally through approximately thirty distributors.
