Online bike fitting

Your bike fit measured, not guessed

Pedalyze checks your position against professional fit ranges in under a minute. No studio visit, no €200 session, no waiting for an appointment.

Fit reportSample analysis
Fit report
1

Knee stays quite bent at the bottom — saddle is likely too low.

2

Hip is very open — comfortable, but costs aerodynamics.

3

Arms are tucked under the torso — reach may be too short.

Stop guessing. Ride further without the pain.

Pedalyze brings precision biomechanics to your home setup — at a fraction of the cost of an in-studio fit.

No stickers or markers needed

Simply upload a photo in your normal kit. Pose detection finds your hip, knee, ankle and shoulder joints automatically in seconds.

Spot fit factors linked to discomfort

Instantly measure your exact saddle height, knee flexion and KOPS — angles commonly associated with knee pain, lower back fatigue and hand numbness.

Pro fit ranges, made simple

Get a clear pass, warn or fail on every angle, against fit ranges for road, comfort or TT. Then share a link so your own fitter can check it with you.

Sources: knee flexion follows Holmes, Pruitt & Whalen (1994). The other ranges are our reading of common fitting guidance. Pedalyze is independent and not affiliated with Retül, BikeFit or any other fitting system.

Pedalyze or a studio fit: when each makes sense

A professional fitter and Pedalyze do different jobs. Pedalyze is a first check you can do at home, and a way to compare your position before and after a change. It does not replace a fitter.

Tips to improve your fit

Ranked so you tackle the biggest issues first.

Fix first2
  • 1
    Hip angle6 o'clock (bottom of stroke)

    Hip is very open — an upright position. Fine for comfort, costs aerodynamics.

    An overly open hip pushes your torso upright, adding frontal area and drag.

  • 2
    Shoulder angle6 o'clock (bottom of stroke)

    Arms are tucked under the torso; reach may be too short.

    A short reach loads the lower back and can restrict breathing.

Worth fine-tuning1
  • 1
    KOPS offset (3 o'clock)3 o'clock (crank horizontal)

    Knee sits ahead of the pedal spindle — try moving the saddle back.

    Knee ahead of the spindle increases strain on the front of the knee.

Video · beta

A photo is one instant. Your pedal stroke is the whole story.

Film about 10 seconds from the side. Pedalyze measures every angle through the full crank cycle, not one frozen frame.

  • Every angle, all the way round

    Knee, hip, torso, elbow, shoulder and knee-over-spindle, measured across the whole stroke instead of a single frame.

  • Cadence and ankle technique

    See your cadence and how your ankle moves through the stroke — things a still photo cannot show.

  • A fit score, and how much to trust it

    One weighted score for the whole position, next to a confidence rating based on how good the clip was.

  • The clip never leaves your device

    The analysis runs in your browser. The video is never uploaded — only the measurements, and only if you save them.

How it works

Four steps, and you can repeat the last two as often as you want.

  1. A cyclist on a smart trainer, filmed side-on by a phone on a tripod.1

    Take two photos

    Side-on, with the cranks at 6 and 3 o'clock. Follow the capture guide on screen.

  2. A tablet showing the rider with the knee angle measured on the photo.2

    Get your fit analysis

    Pedalyze measures your position and shows which angles are outside the reference range.

  3. A cyclist adjusting the saddle height with an Allen key.3

    Make an adjustment

    Use the recommendations to change your saddle, bars or cleats.

  4. A tablet comparing the position before and after the adjustment.4

    Test again

    Upload a new photo and see if your position improved.

When riders check their fit

Anything that moves your body or your contact points changes your position. These are the moments worth a check.

New bike day

The shop set it up by eye. Check the numbers before your first long ride.

Knee pain on long rides

Saddle height and fore/aft cause most knee complaints. Measure both in a minute.

New shoes or cleats

A different stack height moves your saddle height by millimetres you can feel.

Numb hands or a sore back

Check your reach, your bar drop and how much weight your torso angle puts on your arms.

Going lower and faster

See how far you can drop the front end before your hip angle starts to cost you power.

Setting up the indoor bike

Copy your outdoor position onto the trainer bike, and measure it instead of guessing.

Fitting a partner's bike

One photo each. No second appointment and no second fee.

After a fitting session

Confirm the changes stayed where the fitter put them, and re-check every time you adjust.

Your photos stay yours

You are sending pictures of your own body. Here is exactly what happens to them.

Video never leaves your device

The video check runs fully in your browser. The clip is never uploaded — only the measurements, and only when you save.

Photos are stored for you, not sold

Photos go to private storage tied to your account so you can compare over time. We never sell them and never share them for advertising.

Delete them whenever you want

Remove any analysis from your history at any time. Run one without an account and the photo is deleted automatically after 7 days.

Questions riders ask first

Is Pedalyze free?

Yes. You get 1 report every 7 days with the full angle overlay and pass/warn/fail results, with no credit card. The €29 Fit Session pass is one payment for 30 days of unlimited saved analyses, comparisons over time and PDF export. There is nothing to cancel.

Is my video uploaded?

No. The video check runs in your browser, and the clip never leaves your device. Only the measurements are saved, and only if you save them. Photos are different: they are stored with your account so you can compare over time. A report run without an account is deleted after 7 days if nobody claims it.

Can Pedalyze replace a bike fit?

No. It is a first check for the common issues: saddle height, reach, bar drop. If you have pain that lasts after rides, an injury, a clear difference between your left and right legs, or you race at a high level, see a professional bike fitter or a physio. You can share your report with them.

Which bikes and positions does Pedalyze support?

Three fit styles: road/endurance, comfort/upright and TT/triathlon. You pick one before the analysis, and Pedalyze compares your angles with the target ranges for that style. Photos and clips must be taken side-on.
