Ripping a set of banked turns without touching your brakes.
Clearing a rock garden that seemed impossible two months ago.
Getting to the bottom of a hill and screaming uncontrollably with joy.
Eating and drinking and slightly overstating how rad you got after a ride.

We love mountain biking.

We love building mountain bikes that deliver those same moments of exhilaration. We love surprising people with how capable a well-designed hardtail with a custom geometry designed specifically for your riding style and terrain can be. And we especially love that a well-built titanium mountain bike can literally be as good as new after decades of hard riding.

We can build mountain bikes for every wheel size and any tire size up to 4” fat bike tires, and for any use from single track trail riding to bike packing to epic winter snow rides.

It’s been about a year since I received my Firefly and I could not be happier. The bike is everything I hoped it would be and more. It’s fast and stable on both the road and gravel. It accelerates beautifully and is nimble on the CX course. I commonly refer to it as “The one bike to rule them all!” You guys are amazing and I am so thankful to be able to ride such a wonderful machine. The compliments I receive are endless.

I am fortunate to have a few other custom bikes – both titanium and steel – and I only point that out to offer comparison to the Firefly. My Firefly is the bike I always want to ride. There’s just something about how it feels and responds that makes me want to ride it. So, thank you and please pass my gratitude on to the rest of the FF crew.
