Preventing bicycle theft
Parking your bike correctly
Park in a visible place: It is not advisable to leave bikes in remote locations that are hardly visible. Thieves know that they can operate there relatively undisturbed.
Therefore, public places that are well frequented are advantageous. Even better are enclosed spaces such as basements or lockable bike boxes.
Connect your bike
- Always lock the wheel to the frame to a firmly anchored object (e.g., bike rack), even for short absences.
- Thread the lock chain through the frame and wheel to increase security.
- If possible, additionally secure sensitive parts such as the seat to the frame.
Find your bicycle
Save frame number digitally
A distinctive code of letters and numbers on the bicycle makes it easier for lost property offices and police to assign it to the owner – without relying on manufacturer databases. Additionally, bicycle thieves tend to avoid coded bicycles, as they are difficult to sell.

- E-Series E-Bike: under the bottom bracket of the frame
Track bicycle
Bicycle trackers help deter theft by enabling owners to track their bike in real time. In case of theft, the bike can be precisely located to forward the position to authorities for recovery.

Principle "Prioritize frame + rear wheel"
1. Core components
· Lock the frame and rear wheel to a firmly anchored object (e.g., bike rack) with a lock

For high-quality saddles, we recommend using additional theft protection chains. -

Tracking devices work with Apple's "Find My" network. They constantly send Bluetooth codes that are received by Apple devices like iPhones and reported to iCloud. Their owners do not notice this and cannot influence it. Third parties cannot trace the code back to a specific user. Only the owner of the locator can check the location of their tracker in iCloud.
Even if the bike is unfortunately stolen, the locator can provide the police with location records as additional evidence, thereby increasing the likelihood of recovery. At the same time, if you have taken out insurance, you can use the location information provided by the tracker as proof of bike theft when filing insurance claims, which helps the insurance company confirm the authenticity of the theft and improves the efficiency of your claim. -
Don't worry, the tracker contains a 210 mAh lithium battery that lasts for half a year and is easy to replace.

GPS devices can be used for tracking, but they have some significant disadvantages:
The battery only lasts a few days or weeks, whereas the tracking device can operate for half a year without a battery change.
GPS trackers are significantly heavier and larger. Our bicycle accessory weighs only about 100 grams with the tracking device and screws.
GPS devices are much more expensive, often more than 200 euros. In addition, the required mobile phone contract usually incurs monthly fees. Our solution is much cheaper and has no ongoing costs.
