Every bike that Firefly makes is custom.

As you browse our bikes, one of the first things you’ll notice is that we don’t have catchy model names. The reason is simple: every bike we make is custom. Maybe you want a super stiff race bike, maybe you want a comfortable bike for getting lost on dirt roads, maybe you want a commuter with all the bells and whistles, or an all-day mountain bike, or something totally different.

No series of models can capture the range of your needs and our abilities. If your bike falls between a road and a cross bike, or a cross and a mountain bike, no problem. Start with what seems like the closest match and we’ll work out the details from there. Let the dream begin…

As a designer, sometimes you get a commission that really jives with your hobbies. Graphic artist Iancu met a Japanese Cyclist through the Rapha Cycle Club and designed him a dream bike with Firefly Cycles. #carbon #fireflybicycles #japan #titanium

The @bostonbikeunion is looking to hire a full-time community organizer to focus on membership and bicycle advocacy in the Dorchester, Roxbury, Mattapan and Hyde Park neighborhoods.

Three months into our partnership with @coolerclimate and we've neutralized 58 tons of CO2, the equivalent of planting almost 1000 seedling trees and covering the carbon footprint of every bike and frame we've shipped since we started! https://fireflybicycles.com/carbon-neutral-manufacturing/

I Took the bike out for its first voyage today. Holy crap!!! I love it! It’s absolutely amazing!!! It’s soooo comfortable, fast and responsive. It’s so much lighter than the IF. You guys did an amazing job back then building that, but this bike is going to change everything. It really blows me away.

See the build
