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 road bike built for fast group rides, or a gravel bike that will be as capable for racing Unbound as for slowly getting lost on your local dirt roads, or a commuter with all the bells and whistles, or an all-day mountain bike to bikepack through Alaska, or something totally different.

In every case, your Firefly starts with how you want to ride. Tell us your riding goals, needs, and preferences, and we will work with you to design the perfect fit, frame geometry, tube selection, frame options, finish, and components to make your dream bike a reality.

I know you probably here all the time how great your bikes are but I wanted to let you know that this year at Unbound, my FF1455 was the perfect bike for the mud, hail, torrential rain, wind and water fest.  The only thing weather wise I did not encounter was a tornado.  Because you built the wider chain stay, I ran 50 G One RX tires and had not an ounce of mud issue.  I literally walked 50 feet the entire day due to the 3.5 feet of water in the tunnel.  I could have road it but did not want to submerge the bottom bracket.  Ended up finishing at 14:07 (20 minutes spent between 2 flats)  beating the sun.  Considering the weather, I was pleased with my performance.  The Firefly was absolutely amazing and chewed up everything Unbound threw at it.
This bike has never disappointed me once between all the rides including SBT, Bighorn, and now the ultimate test of Unbound 2026.
