FAQs

Contact
Do I need a trainer or a roller?

Yes, a bike trainer or roller is essential for ensuring precise results during your bike fit. While you can simulate pedaling against a wall or pedal backward, these methods may not provide the same level of accuracy. For the most reliable fit, we recommend using a trainer or roller. If you don’t have one, consider borrowing from a friend or checking with a local cycling club.

What do I get when purchasing a bikefit?

When you purchase a bike fit with APIIR, you get 60 days of unlimited video uploads, personalized recommendations, and close follow-up if you have any questions. You’ll also receive a detailed report via email, summarizing your old and new positions with explanations for the suggested adjustments.

Which bike types can I fit?

APIIR supports bike fitting across a variety of bike types, whether you ride Road, Gravel, Mountain, Triathlon, or Hybrid bikes. The app allows you to add multiple bikes to your profile, making it easy to select the one you’re fitting at any given time. No matter your choice of bike, APIIR is designed to help you.

What do I need to perform a bikefit?

To perform a bike fit with APIIR, all you need is your bike, a bike trainer to keep it stationary, and a smartphone with the APIIR app ready to guide you. For optimal results, having a measuring tape and basic bike adjustment tools on hand will make it easier to fine-tune your setup as you go.

How accurate is the algorithm?

The APIIR algorithm is designed with precision in mind, offering results that align closely with more expensive, traditional bike fits. Most users who have experienced both APIIR and pricier alternatives report that the outcomes are nearly identical. We recently put our algorithm to the test against the industry-standard Qualisys Capture System, and have refined it even further based on the findings.

How do I get the best results?

To achieve the best results, set up in a well-lit area and wear fitted clothing that contrasts with your surroundings. This allows our AI to precisely capture your cycling position, ensuring that your bike fit is as accurate and effective as possible. Following the in-app instructions closely will further enhance the accuracy of your fit, helping you achieve optimal comfort and performance on your rides.

Where do the optimal positions come from?

The optimal positions recommended by APIIR are grounded in a blend of biomechanics, extensive cycling literature, and the expertise of professional bike fitters. Our algorithm tailors these insights to your unique body composition, mobility, training goals, and any existing pains or injuries, ensuring that your bike fit is not only scientifically sound but also personalized to maximize your comfort and performance on every ride.

Can I fit multiple bikes?

Yes, you can fit multiple bikes with APIIR. We offer flexible packages that allow you to purchase anywhere from one to three bike fits. This way, you can easily optimize the fit for each of your bikes, ensuring that every ride is as comfortable and efficient as possible.

Can I perform the procedure alone?

Yes, you can perform the bike fitting on your own. Just ensure you have a way to securely position your camera while you're on the bike. This could be a friend holding the camera, a tripod, or even a stable surface like a bookshelf or windowsill.
