Selecting the right bike size is one of the most critical steps in every cyclist’s journey, yet it’s often overlooked or misunderstood. A bike that’s too large or too small can limit your performance, cause discomfort, and diminish the joy of riding.

At MyVeloFit, we believe proper sizing should be straightforward, data-driven, and tailored to your body and preferences.

Our approach combines expert insights with modern technology to ensure you’re matched to a bike that fits like a glove—from your first pedal stroke to your longest ride.

The Keys to Comfort, Control, and Injury Prevention

A Properly Sized Bike Sets the Stage for Success

1. Ride Comfort

Experience fewer aches and pains when your saddle, handlebars, and frame geometry align with your riding position. Starting with the right size bike makes fitting a breeze.

2. Performance & Efficiency

Generate more power and maintain better aerodynamics when the bike is scaled correctly to your body dimensions and riding goals.

3. Injury Prevention

Reduce the risk of repetitive strain injuries or numbness by avoiding positions that overextend or cramp key joints.

4. Confidence & Handling

Maneuver with ease and stay balanced through corners and climbs when your bike’s geometry suits your riding style and flexibility.

ONE SIZE DOESN’T FIT ALL

Why Traditional Charts & Labels Can Be Misleading

Many cyclists rely on sizing charts, or even worse just the “size” —small, medium, large—to choose their bike. While these tools offer a starting point, they rarely account for individual differences like leg length, torso proportions, and riding goals. This can lead to a bike that seems correct on paper but feels off once you hit the saddle. MyVeloFit aims to break this cycle of guesswork by focusing on the rider first, ensuring your new bike is tailored to your body, not the other way around.

Combining Data-Driven Insights With Real-World Experience

At MyVeloFit, we harness advanced fit principles and user-friendly tools that guide you toward a bike size that complements your body and riding aspirations. By taking a virtual fit first approach to sizing we help you choose the right size bike for the riding position you are targeting.

Fit-First Sizing

Instead of matching you to a bike based solely on your height or inseam, our fit-first methodology considers a range of factors—from detailed body dimensions to your bike fit goals. This holistic approach helps you bypass arbitrary sizing charts and ensures a more precise match.

Practical Steps to Find Your Perfect Match

1

Gather Essential
Measurements

Our AI video tool will help you record key body dimensions and will point you in the right direction especially if you’re considering multiple frame geometries.

2

Find Your
Target Position

Not every rider wants or needs to be in the same riding position. We help you choose your target position to make sure the bikes you get matched with will fit just right.

3

Fit-Specific
Adjustments

Adjustments like saddle height, handlebar reach, and stem length can all be virtually tweaked to dial in the perfect position.Figure out what changes might be needed to make the bike you’re eyeing up fit even better.

4

Aim for a
“Neutral” Posture

Seek a position where your arms, shoulders, hips, and knees work in harmony, reducing strain over short spins and long endurance rides alike.

5

Compare

We know you probably have a few bikes on your short list, so you can compare how every bike you’re considering stacks up with regards to your fit to help make the best choice.

Works really, really well

Their [MyVeloFit] stuff is really, really, good and works really, really well”

~ Tim Cusik (BaseCamp)

An Excellent Product!

I have been using myvelofit for just over one year in a large bicycle retail shop and I do about six to eight fittings per week. It is an excellent product that in the hands of an experienced fitter generates very in depth information about riding position and ranges of motion, comparable to other fit systems such as Retul.

FAQs

1How does MyVeloFit’s online bike fit work?

Our online bike fit process is designed to mirror the process used by professional fitters around the world. If you've had a bike fit before it should feel quite familiar, and if it's your first time rest assured it’s tried and tested. At it’s core our online bike fit includes 5 steps:

Complete a mobility assessment
Set goals for your bike fit (bike type and fit goals)
Record and upload a riding video (on your trainer)
Analyze results & make adjustments
Adapt to changes

Then repeat. Online bike fitting, like in person bike fitting, is iterative. So it’s completely normal to repeat steps 3 through 5 several times as you analyze, adjust, and adapt. The human body doesn’t always respond the way you might expect, which is why you need to keep reassessing the impacts of each adjustment you make. If you’d like to learn more about the process (and you should) we have a full blog post that goes into much more detail.

2How do I get set up for my online bike fit?

The short answer is that bike sizing is the process of choosing the right size of bike, and fitting is the process of adjusting the bike to suit your body and riding needs. To understand more about how these processes are separate but deeply related, check out our full blog post on the topic.

3Can I fit my bike from both sides?

You sure can! Uploading a video from either your left or right side is exactly the same process and can be completed in the same fit session. Be sure you place your camera consistently relative to your bike on both sides to ensure consistent results. Many riders have some asymmetry between left and right, so don’t be surprised if they aren’t exactly the same. At MyVeloFit we’re committed to help every rider improve their riding experience. To help remove any doubts, if we’re not able to help you improve your riding position within 30 days, we’ll give you your money back so you can seek out another approach.

4Can you transfer my fit from bike X to bike Y?

While we do not have a dedicated tool for transferring your fit between bikes, using MyVeloFit can be incredibly helpful to help you transfer your fit. What we recommend is starting a fit session for the reference bike to have a complete set of measurements of your body's position. Then use our easy guide to measuring your bike to document the bike’s measurements. Use those measurements to set up the bike you’d like to transfer the fit to, then finalize your fit by using MyVeloFit to confirm your body is in the same position as the reference bike.

5How do I change my fit goal?

As your fit goal is a key determinant of the recommendations we provide, it is not possible to change the fit goal in a session once it has been created. For Pro users, the easiest path forward is simply to create a new session with the fit goal you’d like. For Enthusiast users if you believe you may have made a mistake in setting up your session, simply reach out to our support team at support@myvelofit.com

6My bike can’t make the adjustment you’re recommending, is the software broken?

While bike fitting is about bringing together the rider and bike to work better together, it is perhaps more accurate to think about it as adapting the bike to work for the rider. The recommended adjustments provided in your fit report provide the changes to the bike required to move your body towards a better riding position for you. Unfortunately if your bike has run out of adjustments, this is a good indication the bike is not the right size/geometry for your needs.

How It Works:
Your Personalized Bike Fitting Process

Starting with this mobility-based foundation, MyVeloFit’s proprietary algorithms transform raw kinematic data into actionable insights. By incorporating the results of your assessment into the broader context of your posture, pedaling style, and equipment, we provide fit recommendations as unique as you are.

Step 1

Setup and
Initial Assessment

Begin your MyVeloFit journey by creating your profile and completing a quick functional mobility assessment. This step equips our algorithms with essential information about your body’s range of motion, ensuring that every subsequent recommendation is grounded in understanding your unique biomechanics.

Step 2

Record
and Upload

Mount your bike on a trainer and record a short video following our simple guidelines. With just a smartphone or tablet, you capture the video needed for our AI-driven kinematic analysis. No specialized tools, no complicated sensors—just basic video footage that reflects your riding position.

Step 3

AI-Powered
Analysis

Our advanced AI technology compares your video against a vast database of professional fits. It interprets posture, pedaling symmetry, joint angles, and more, using markerless motion capture to highlight opportunities for improvement. By analyzing how you move dynamically, the system identifies precise adjustments that elevate comfort, boost efficiency, and reduce strain.

Step 4

Receive Custom Fit Recommendations

Within minutes, a comprehensive fit report outlines each suggested change, from subtle saddle height shifts to optimizing handlebar reach. These recommendations are data-driven, discipline-specific, and completely personalized, embodying both the client’s feedback for advanced customization and the website’s focus on delivering expert-level insights.

Step 5

Fine-Tuning
and Support

Implement the recommended adjustments and experience the difference immediately. Should you have questions or wish to refine your setup further, our support team and the MyVeloFit platform are there to guide you. As your riding evolves—be it through improved fitness, new cycling goals, or upgraded components—you can revisit the process, allowing the AI to adapt and continually optimize your fit.
