Double Dog Studios

A small family studio

Bike Fast Fit is made by the Millard family. We are cyclists and software people, not a big company, and we like it that way.

Why we build this

A good fitter watches you ride, asks what hurts and when, and works through what a number on its own cannot explain. A good deal of what we make is for them. Professional fitting equipment is expensive, and we would rather Bike Fast Fit Pro be a tool a working fitter can simply buy, so the people handling the hardest cases can keep doing it.

Most riders never get a fit at all, and the ones who do usually get one, once. Then things change: a new saddle, new shoes, a new bike, a body a few years older. Checking again every time is not realistic when checking means an appointment.

So we built a version you can do yourself, on the bike you already own, as often as you like. Bike Fast Fit reads your position from high-speed video and tells you what to change, in millimeters rather than a score. For a complicated fit or a nagging injury, see a fitter.

We are passionate about everyone riding a bike that fits them well, whatever they can afford to spend on it. That goes for riders doing their own fits, and for the fitters helping people with the more complex cases. We build for both.
