Science and Magic

"Mass-produced by Five"

Firefly Bicycles - Handmade in Massachusetts

Do not berate yourself if this is the first time you have heard of Firefly. We get the impression that they quite like it that way. Not because they are unfriendly (they are the opposite) but because there are only four (actually normally five - Paul is soon to return from paternity leave) of them and they have to work exceptionally hard to build around one hundred totally customised bikes a year. Speaking of a year, that is how long it sometimes (not always) takes to build your bike after the order has been curated and placed.
A glorious year of imagining and barely concealed excitement. It is an essential part of the Firefly process.

History in Numbers

Firefly don't do models names or stock sizes. Beyond the general bike category, every little detail is custom, and every project is numbered, photographed and placed prominently in The Firefly Gallery - a place in history. Firefly owners proudly refer to themselves via their allotted number. Firefly are the living antonym of corporate and mass-produced. Or more accurately - mass-produced by five.

Firefly and Cyclefit

We have been working with Firefly for many years now. They kindly make the beautiful seat-posts and seat-clamps, that we prefer to include on all of our custom Seven builds, like this Axiom XX

And now we are proud to be invited to be only their second retail partner in the world.

What our clients say

  • "The personal service from both Phil and Julian is second to none. They have such a wealth of experience in fitting that they can almost tell at a glance if something is just a little off. It felt as though it didn't matter how long it took to get the best position possible - even for an amateur cyclist like myself. Can't recommend them enough."

    Susan

    Cyclist

  • "Hey Julian and Phil, I hope you are both well. I just completed a 21 hour week on my new 165mm cranks and I am in love. They feel so so great! Thank you for all your help. I’ve never felt so comfortable on my bike before. All the best, Hannah"

    Hannah Barnes

    National Champion / Professional Bike Rider

  • "I tried the shorter cranks today and I like them - it feels like it's less stress for the back and it seems easier to ride higher cadence. In the end I had a good Tour with no back problems. Thanks for your help!"

    Bauke Mollema

  • "A very thorough, professional and personal service. I was keen to analyse my bike position after breaking my hip. The custom footbeds and alterations to my position feel really good, just wish I’d come sooner! Many thanks"

    TD

    Endurance MTB rider

  • "I'm new to cycling so needed some support on finding a bike that would be right for me. Julian couldn't have been kinder or more supportive, he took time to find out what I wanted from my cycling and then looked closely at my physical structure to ensure that the bike is a comfortable fit for me. It really is a 5 star service and far exceeded my expectations."
