We are continuing to work at a reduced production capacity to help slow the spread of Covid-19. We are keeping up all non-production work remotely in the meantime, including fit and frame design work for existing orders and continued prompt customer service for all. If you need a distraction and want to talk about what your dream custom bike would look like or have a bike fit question, even if you have no intention of ordering one from us, please feel free to email us anytime at kevin@fireflybicycles.com. We hope your bike can be a source of comfort through this period, no matter what type of bike it is. And most importantly, stay safe and healthy.

- The Firefly Team

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…

I picked my bike up on Saturday – and YES, it’s AMAZING!!! I put it together in about 3 minutes and immediately jumped on it and took it out for a fast 55km ride at 32F. Fits like a glove. Thanks for all of you attention to detail, I’ll be marveling over it for weeks! The three of you make something that is so technically complex seem so simple – I've been amazed at that from the beginning of this process. Thanks again.”

Today is Breonna Taylor’s 27th birthday. She should still be here. Instead, she was killed by police executing a No-Knock warrant. They shot and killed her while she slept. The man they were looking for HAD ALREADY BEEN ARRESTED EARLIER THAT SAME DAY. Enough. No more.

The cops shot Breonna Taylor 8 times and haven’t been fired or charged. Let’s celebrate her life by bringing her killers to justice.
