    Asked questions

    Not having a trainer, could I just lean against the wall and pedal in the reverse direction?

    That's a creative solution and it should work for a rough estimate.  Pedaling under load changes some angles, so reverse pedaling won't be as accurate.

    Does Bike Fast Fit provide recommendations on optimal angles, or are they something you have to determine?

    Bike Fast Fit provides basic recommendations on angles for over 20 different common measurements. The measurements descriptions include a range of angles typical to the measurement.

    Does the video need to be the right side of the bike and rider?

    Bike Fast Fit works with video of right or left side as well as video from the from the front or rear of the bike and rider.

    I don’t have 10 feet of space. Would it help if I had a wide angle lens for the iPhone?

    We recommend 10 feet but it isn’t necessary. You can use whatever distance you have available. You may need to take 2 or 3 videos to capture the enough of you and the bike to measure the angles you want measured.

    Will this work on a mountain bike as well?

    Bike Fast Fit will work with all types of bicycles.

    Will there be an Android version?

    We are a small company with limited development resources and a long list of ideas for improving Bike Fast Fit.  Our goal is to build the best bike fitting app.  We decided to concentrate on improving the iOS app rather than build an Android version.

    How can I export a video I can post on You Tube?

    Export the video to Photos. In Photos the video is a .mov file and can be uploaded to YouTube or wherever you want.
