When the bars are too far away or too low, your back and arms do the stretching on every ride. 2BikeFit measures your torso and elbow angles from one phone video and shows whether your reach and bar height fit you.
Free scan. You'll need your bike on a trainer or rollers, your phone, and about ten minutes.
Back, neck and hand discomfort usually trace back to the same few settings. Each of these is something 2BikeFit measures.
Lower back
Reach too long or bars too low
What we check: Torso angle against the range for your position, so you can see if you are stretched too far.
Neck and shoulders
Locked arms and a long reach
What we check: Elbow angle while you ride, which shows whether you are reaching for the bars.
Hips rocking, back sore
Saddle too high
What we check: Knee angle at the bottom of the stroke, since an over-high saddle makes the pelvis rock to reach the pedal.
Two angles tell you whether the cockpit fits: how far your torso leans forward, and how bent your elbows are. Here is the reach check on two recordings of the same rider. Between them he only raised his saddle, and that alone moved his elbow angle back into range.
The number drawn on the video is the live angle; the verdict uses the average over the whole clip.
Recording 1
Your torso posture is within the target band, but your elbow angle is outside it: your arms are more bent than the target band.
Recording 2, saddle raised
Your handlebar height and reach are within the target posture window.
Side on, on your trainer, 30 to 90 seconds of easy pedaling.
The AI tracks your joints and measures every angle against its target range.
See what is off and which way to move it, then record again to confirm.
Real feedback from cyclists who fitted their bikes with 2BikeFit.
“A remarkable bike-fitting app. After trying it, I was impressed. For the price, it offers plenty of attempts and, above all, the results are easy to reproduce. I love it, I'm sold! It helped me feel comfortable on my bike and rediscover great sensations while riding.”
“I tried it too, and it really is a great tool. The one thing I'm still missing is a recording from the front so that riding position can also be analyzed from that angle.”
“I had my road and gravel bikes fitted to my specs. The website is incredibly user-friendly and clearly structured, and any question I had was answered right away by the tips. I love that you focus on one point at a time and only move on once it's sorted. 2Bikefit is absolutely brilliant, I'll definitely use it for future bikes.”
“The UI and reasoning are among the best I've tried. I really like that the results are presented as ranges. This app has the potential to be very good.”
“As a new cyclist, I absolutely loved how well this app guided me through every bike-fit adjustment. The recommendations were clear and easy to follow, and they helped significantly reduce my knee pain. I now feel much more comfortable and confident on the bike!”
“2Bikefit is the result of a lot of study, biomechanics, computer vision, and the science behind a proper bike fit, built so a single video gives you what used to require a studio. I held it to the standard I'd want for my own bikes, and I've used it to fit myself and my friends before putting it in front of anyone else.”
