Years before Lance Armstrong won a single Tour de France, Tyler Evans was building bicycles. As an avid road and mountain biker, Evans welded frames at Cambridge-based Merlin Metalworks—famous for pioneering titanium bike frames—while earning his degree in sculpture at MassArt in the ’90s (Merlin was acquired by Saucony in 1998). “I’ve always been fascinated by the way bikes blend man and machine,” he says. “They’re the ultimate biomechanical object.”
Evans eventually left Merlin for the custom shop Independent Fabrication (now based in New Hampshire), where he met fellow bike-building pros Jamie Medeiros and Kevin Wolfson. In 2010, the trio decided to start their own company, which they named Firefly to evoke “warm summer nights, lights flickering, and a sense of awe and comfort,” Evans says.
Out of their industrial-chic Dorchester workshop, they produce artisanal bikes for clients across the world who want to get deeply involved in the design of their custom-built machines and value exceptional performance.
Firefly’s frames are built from U.S.-made, aerospace-grade titanium tubes that were originally manufactured for building jets and spacecrafts. This very light material, which can cost as much as $10 per inch, is coveted among bike aficionados for its strength and stiffness. “Titanium is incredibly dent-resistant,” Evans says, “so we can really shape it to make the bike more comfortable and performance-oriented.”
The first step in creating a Firefly bicycle involves a consultation with the shop’s frame designer, Kevin Wolfson, who works with clients to determine how the bike will be used (commuting, off-roading, or racing), and to establish the rider’s personal biking preferences.
Wolfson then lays out the frame’s basic geometry, and specifies the size and shape of the tubes that will be used to build it. “Even tube thickness and diameter affect how lively the frame will be,” Evans explains. “You can really tune it to the body to create comfort.”
