Fit Forms

We have developed fit forms specific to each of our models in order to build you the properly sized and configured bicycle. If you’re ready to get your hands on a new Firefly, begin here by completing the correct Firefly Fit Form below or by contacting Kevin Wolfson at 617.825.3473.

Testimonial // FF1427

This bike is absolute perfection, every detail is so spot on. I love the low bottle mounts, the fact that I can shoulder the bike with bottles on, NO TOE OVERLAP, the third bottle clears the inner chain ring, I can climb out of the saddle without banging my knees on the bag, and the front end somehow doesn’t flop around when standing which is a miracle compared to all of my bikes with porteur racks. And I can ride with no hands with the rack/bag! I feel like all of my minor gripes with every single one of my other bikes has been solved.

The handling is so intuitive, I came down the Blue Hills access road chicane like I’d been riding the bike for years, it feels so planted and stable but also very responsive and plush in a way I never imagined. I am totally and completely delighted with this bike, beyond what I had imagined.
