Every bicycle 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…

A quick note to say that the bike is built and tested over 80 cold and rainy English ks at the weekend. The ride was fantastic – geometry is spot on, it’s v stable and compliant with a bit more zip than I expected from ti. I did a few 1000+ watt sprints and and felt super stuff also. Lots of admiration from my riding buddies. It’s perfect for what I want so a big thanks you to you and the team.
