Andrea Calvo, 15, Develops App to Diagnose Bicycle Noises
Andrea Calvo, a 15-year-old from near Milan, has developed BikeClab, an innovative app designed to help cyclists identify and address mechanical issues based on the sounds their bikes make. An avid mountain biker who handles his own bike repairs, Andrea created BikeClab to bridge the gap between vague descriptions of bike noises and precise mechanical diagnoses.
Addressing the Noise Diagnosis Challenge
Cyclists often struggle to pinpoint issues when their bikes emit unfamiliar sounds. Traditional searches yield limited results, and forums provide varied advice, making it challenging to identify the exact problem. Andrea’s solution was to develop an app that transforms these imprecise descriptions into specific component checks. For instance, a cyclist might describe hearing a “tac” sound when pedaling hard; BikeClab would guide them through a diagnostic process to identify the underlying issue.
How BikeClab Works
Available for free on iOS and Android, BikeClab’s interface begins with a text field where users can describe the problem in their own words, such as “makes a ‘tac’ sound when I pedal hard” or “brake rubs on one side.” The app then prompts users with targeted questions, similar to a mechanic’s inquiry, to narrow down the potential causes. Based on the responses, BikeClab provides a list of probable causes, ordered from most to least likely, along with step-by-step repair guides and maintenance reminders.
User Engagement and Data Insights
As of September 2, 2026, BikeClab has facilitated 2,270 diagnoses from 875 cyclists, with 1,145 bikes registered. Andrea actively documents the app’s development and shares bike maintenance tips on Instagram, fostering a community of engaged users.
Understanding Cyclists’ Descriptions
An intriguing aspect of BikeClab is its collection of 2,500 user-submitted problem descriptions between April 7 and September 1, 2026. Notably, 6.4% of these descriptions did not mention any specific bike component, focusing solely on the noise and its occurrence. For example, users reported hearing a “creak” when the bike is stationary and moved back and forth or a “click” when lifting and lowering the bike. This highlights the importance of understanding cyclists’ own descriptions to accurately diagnose issues.
Component-Specific Issues
When users did specify components, the most common issues reported were:
-
Brakes: 26.7% of problems, with “squealing” being the most frequent complaint.
-
Gears and Shifting: 19.2% of issues, with “noise only on certain gears” being a prevalent concern.
-
Chain and Drivetrain: 18.2% of problems, often involving “creaking” sounds during pedaling.
-
Suspension: 14.7% of issues, including “noise upon landing” and “oil leakage from the stanchions.”
These insights underscore the app’s effectiveness in pinpointing specific mechanical problems based on user-reported symptoms.
Limitations and Future Directions
While BikeClab is a valuable tool for diagnosing common bike issues, it is not infallible. The app is continually updated to improve diagnostic accuracy, with a dedicated page listing reported errors and their corrections. The primary goal is to enhance diagnostic precision rather than adding new features, aiming to map real-world bike issues component by component using the language of everyday cyclists.
