In times of connected bicycles, e-bikes, and smart trackers, the topic of GPS data and tracking is becoming increasingly relevant – not only for manufacturers, but also for every cyclist. What sounds harmless actually poses significant risks to privacy and personal data.
GPS data are digital movement profiles.
Every GPS tracking device, whether a classic GPS tracker or an Apple AirTag, collects location data. This data reveals:
Where one lives and works
Which routes one regularly travels
When you are at home or on the go
Potentially personal routines, hobbies, or fitness habits
Such information may seem harmless at first glance, but if misused it can lead to serious problems – from unwanted advertising and targeted surveillance to incentives for theft.
GPS data is valuable
Nowadays, GPS and movement data have become an important economic asset :
Providers of bicycles, e-bikes or GPS trackers often use movement data to evaluate usage behavior or to make product optimizations .
Insurance companies could also use location data to calculate risks.
Data leaks or hacks can cause movement profiles to fall into the wrong hands – with consequences for security and privacy.
AirTags are not a traditional GPS device, but they use the Apple network to share location data. This means:
Every AirTag can theoretically be tracked by Apple's servers.
Movement profiles are created when the same device is regularly used on a bicycle.
Without conscious control over "lost mode" or privacy settings, you are constantly revealing movement data.
This can be particularly problematic in urban areas – from stalking to targeted theft planning.
With the introduction of the second-generation AirTag, Apple is bringing some significant changes that are also relevant for bike trackers. The AirTag 2 uses a new ultra-wideband chip that significantly improves precision location tracking and increases the range of the "Precision Finding" function by approximately 50%.
This means that a tracker attached to a bicycle can potentially be located over greater distances and more accurately than with the original model. Furthermore, Apple has optimized the Bluetooth chip, thereby increasing the detection range in the Apple "Find My" network.
The built-in speaker is up to 50% louder, which is convenient but may also affect anti-stalking alerts, as they will be more easily noticeable. Apple also emphasizes improved privacy and security features, including frequently changing Bluetooth identifiers and new safeguards against unwanted tracking , designed to limit misuse for surveillance.
Data protection in the cycling world: Why it's important now
E-bikes, smart bikes and GPS trackers are spreading rapidly.
Users often underestimate the fact that location data is not anonymous.
Those who lose track of things permanently reveal sensitive information.
Conclusion: GPS data is not a technological toy, but a critical data privacy factor . The installation of an AirTag or GPS tracker on a bicycle should be a conscious and informed decision – not only to protect the bicycle, but also one's own privacy.
Recommendations for cyclists
Only use trackers whose privacy policies are clear .
Deliberately hide the tracker, but also use the control mode regularly.
Only store movement data in secure apps or networks.
Alternative: Devices with local storage instead of cloud connectivity
In the future, bicycles will become increasingly smart – from GPS trackers to e-bikes with cloud analytics. Anyone who doesn't actively protect their data is handing over detailed movement profiles to third-party companies and hackers .
Convenience should not come at the expense of privacy. Cyclists should consciously decide what data they share and question tracking solutions before installing them.
