The makers of the AI bike fitting app MyVeloFit have announced the launch of a new AI-powered bike and size finder platform, with a goal of removing uncertainty over which frame size is right for the individual.

Finding the correct bike size is essential for ensuring maximum comfort, injury prevention and enjoyment of any bike. However, according to MyVeloFit, “bike sizing is broken”. As they see it, consumers now have more bikes and geometries to choose from than ever before, but little way of understanding how each bike will fit.

Understanding bike geometry charts can sometimes feel like working out a mathematical riddle in a maze resulting in confusion for even the most experienced riders. Furthermore, with so much variation between brands, frames, and styles, it is increasingly easy to get lost in the numbers.

With such wide variations in fits between frames, all marked with the same size, it’s no surprise there is so much confusion around bike fit.

MyVeloFit suggests that “sizing charts only help a cyclist understand at best if a bike should fit, but not how a bike fits.” That’s where their new app comes in. Furthermore, the app developers also point to the increase in direct-to-consumer bike sales and supply shortages resulting in more riders than ever buying bikes unseen and unridden. Meaning by the time the bike arrives, it is too late for the old standover height failsafe check.

MyVeloFit believes a good position on the bike starts with selecting the right bike and so the app first determines the rider’s target riding position and then finds frames to match. That flips the lid on many rider’s experiences of buying a bike and then finding a position that works.

The web-based app’s software and algorithms take a fit first approach to sizing that helps match bikes to each rider and their unique target position. ‘Fit first’ simply means the app first establishes the rider’s target position before then searching for frames which can accommodate this position.

The web-based app first makes a 3D skeletal model of the rider taken from a video uploaded by the user.

MyVeloFit claims this process helps riders select a frame that not only matches their body but also reflects how they want to ride. Think frame size guides with rider height bands and add in personal features such as longer or shorter arms, flexibility, riding style, bad back, tight hamstrings etc. The app removes the aesthetics, brand loyalty, marketing, etc to suggest the right frame for you.

The initial release is designed to help riders unsure of which size frame they need to get a better understanding of which frames will work for them.

The process starts with an AI body scan from a simple video captured on a smartphone and uploaded to the MyVeloFit app. The rider is recorded turning around in place twice guided by prompts from the phone.

The scan extracts a 3D skeletal model of the rider to establish their body proportions. Riders then choose their preferred target position based on their body scan, riding style, and fit goals. From here the app offers three riding goals – namely, relaxed, neutral, and aggressive.

The app recommends several bikes and sizes that meet the rider’s fit and riding style requirements.

The app then provides frame recommendations offering riders the best bikes and sizes to match their target position. While complete bikes are recommended based on stock components, riders can customise their fit on the app’s compare page.

Naturally, there isn’t always just one perfect size for every bike and so the app may suggest two sizes for riders to choose from. Selecting a bike will let riders view their unique position on that bike in each size.

Furthermore, not every bike will have a size correct for each individual user and their unique target position and hence some bikes might not be recommended at all. However, the app assigns every bike in the MyVeloFit database a “Fit Score” unique to each user, offering an insight into how each bike is likely to fit the individual. In other words, if you fancy a touring bike but want an aero position there might not be a perfect frame option but the app will at least let you assess the least bad options.

Users can compare their fit on a range of sizes in one frame option or across a range of frames.

From there the app provides an estimated starting setup including saddle height, handlebar drop, etc. At this point, the app will also check key fit requirements such as standover height and saddle height range.

The app intentionally errs on the low side for saddle height and MyVeloFit recommends a complete bike fit with any new bike.

Users can then compare the fit of several bikes to help with the final frame selection. The process can be repeated for different bike types. Road and gravel is already included, with TT and MTB to follow soon. MyVeloFit also has plans to include more customisation with custom frame geometries on the way.

As the app is web-based, no downloads or setups are necessary meaning anyone with a camera and an internet connection can access the platform. The bike sizing app is included in MyVeloFit’s basic free offering, while the brand also offers a once-off US$35 version and a US$75 per year premium offering.
