About Velocraft

Bike Fit Studio

Every rider is unique with respect to biomechanics, riding style and goals. Velocraft’s bike fit studio uses Retul 3D motion-capture technology to dynamically assess a rider’s position, within 1mm of accuracy, and then deliver a bike fit that most comfortably and efficiently maximizes performance.

Retul has helped riders on professional cycling teams like Radio Shack, Sky and Garmin and professional triathletes like Chris Lieto and Craig Alexander improve their performance and can help you too. Through improved fit on your bike, Velocraft will help you get the most out of your cycling experience.

Velocraft's Difference



Most bike fitting specialists fit riders in a static, non-moving position. This is because the traditional fitting tools – tape measures and plumb bobs – do not allow accurate measurements while the rider being fitted is pedaling. Using motion capture technology, the Retul system used by Velocraft records your positions dynamically while in motion, therefore creating the most realistic picture of the your actual pedal strokes and body positions.


Measurements made by traditional fitting tools have one thing in common – they are subject to human error and therefore can be devastatingly inaccurate. Even slight inaccuracies can drastically impact your comfort and performance. The Retul system used by Velocraft is accurate to within less than a millimeter, creating true objective data which can be utilized for the perfect biomechanical fit.

3D Analysis.

Traditional fit data collected in a traditional two-dimensional plane (i.e. video-based systems) is fairly limited because the fitter can only look at one view of a rider at a time. And, when multiple views are considered, they are not connected to one another. In order to make the best fit recommendations, the front and side views must be viewed simultaneously in three dimensions to see how all the applicable movements of the body work together.  The Retul system used by Velocraft uses a 3D motion capture to simultaneously gather data on multiple angles of the rider.

Velocraft's Technology


Retul Motion Capture

Velocraft has selected Retul to help make objective and accurate fit decisions, as a proper bike fit is one of the single most important factors for optimal performance and efficiency, injury prevention, and comfort on the bike. A proper bike fit will not only provide you with the most economic means of expending energy, but will also prevent pain that is common in the knee, hip, and lower back, particularly if you are trying to adapt to a bike you have already have purchased.

The Retul system used by Velocraft reads your movements while you are in motion on the bike, and accounts for all three planes of movement (3D). This type of data cannot accurately be captured with 2D video, static fitting, or eyeball fitting. The Retul system eliminates the guesswork and assumptive nature of bike fit. The result is that you will have a true fit to your bike, maximizing efficiency and performance while avoiding discomfort or injury.

Muve Fit Bike

The Muve fit bike is recommended for properly fitting you prior to making a new bike purchase. Velocraft uses the new, innovative Retul Muve that can quickly be set up for road, mountain, and triathlon positions. The Muve works in conjunction with the Retul 3D motion capture system by collecting your dynamic riding data then immediately making bike adjustments to create the desired final position.

Frame Finder

Prior to purchasing a new bike, Velocraft utilizes Frame Finder, a web-based software program that houses the geometries of bike frames and parts. Frame Finder allows Velocraft to virtually customize your new, complete bike ensuring your new purchase aligns with your proper fit parameters.
