Description
One of the most important factors in a bike fit that provides a good cycling experience and prevents injury is the height of the saddle. Bike Fast Fit EZ is the fastest and easiest way to find the optimal saddle height.
Point an iPhone or iPad at a bike on a trainer (or smart bike or spin cycle) and press the Record button. The app detects when the rider is on the bike and has established a pedaling rhythm. It then records a 3 1/2 second video, enough for 4 to 5 complete pedal strokes.
Bike Fast Fit EZ takes less than 5 seconds to automatically analyze the video, identify key frames, locate body positions and measure important angles and distances. Our proprietary algorithm recommends an amount to raise or lower the saddle.
Bike Fast Fit EZ is available free with full functionality for a 7 day trial period.
Why Saddle Height is Key
If the saddle is set too low, the hamstrings aren’t engaged, forcing the quads to be primarily used. This makes pedaling less efficient and more tiring. Set the saddle too high and the hamstrings overpower the quads at the bottom of the pedal stroke causing a stressful snap in the knee. A low saddle height can lead to a repetitive stress injury of the knee. There is a sweet spot where the muscles are balanced and work efficiently together.
Unfortunately, this sweet spot is small and difficult to hit. Research has found a knee angle between 140 and 150 degrees at maximum knee extension (MKE) is optimal. For a typical rider this translates to a saddle height within a 3/4” (2 cm) range to achieve an optimal knee angle.
In addition, the foot angle in relation to the pedal must also be considered as changes in the foot angle directly change the knee angle. When the saddle is too high, most riders compensate by pointing their foot which increases the foot angle and decreases the knee angle.
In the past, capturing a rider’s knee and foot angles while pedaling has required expensive motion capture systems or complex video analysis programs. These systems require time-consuming setup and are only as accurate as the placement of the sensors or markers. These systems are designed to be used by experienced fitters. Interpreting the results and the changes can be confusing and frustrating.
Bike Fast Fit EZ Technology
Since 2013, our Bike Fast Fit and Bike Fast Fit Elite apps have helped users improve their bike fit. We have collected over 175,000 bike fitting videos and used these videos to develop a sophisticated artificial intelligence system to identify the key points on a bike rider without any markers or user interaction.
We evaluated thousands of fitting sessions from professional bike fitters developed a proprietary algorithm that makes a recommendation on the amount to raise or lower the saddle based on these measurements.
Our first product using this new technology is Bike Fast Fit EZ, an iOS app designed to make it fast and easy to find the optimal saddle height.
