Digital lock
You can lock and unlock your electric bike using the Christiania app. If your locked bike is moved, the IoT system will send a motion alert to your phone.
Auto Lock* ensures hands-free security for the user. The bike locks automatically when the user moves out of Bluetooth range and unlocks when they return.
*This feature is only available for Guardian IoT
Motion notification and alarm
If the locked bike is moved, the IoT device will send a motion alert to your phone.
When a bicycle is locked and touched, warning sounds are triggered. If the bicycle is moved for an extended period of time, a full anti-theft alarm will sound.
Control over your drive
You can turn the bike and its lights on and off, and adjust the assistance level using Christiania Bikes .
The app features a digital dashboard that displays your bike's speed, distance traveled, battery charge level, and much more.
You can also use the navigation feature to track all your trips.
Your digital ID
The unique frame number on your Christiania bike is linked to a digital ID in the app. If someone tries to alter the frame number on your Christiania bike, the IoT device’s digital ID can prove that you are the bike’s owner.

Why can't I unlock my bike?
To unlock the bike, the main battery must be properly installed. Without the battery, the motor cannot receive power, and therefore the bike cannot be unlocked.
Please also note that the battery cannot be charged at temperatures around freezing—this can affect both charging and operation.
How do I install an IoT device on my bike?
Our IoT devices are installed at the factory as standard during production. If you already own a bicycle, the device can also be retrofitted at an authorized dealer.
To ensure proper installation and high quality, an IoT device should always be installed by a dealer.
How do I keep my IoT device up to date?
Updates with new features and services are installed automatically via over-the-air (OTA) updates.
You’ll receive regular push notifications in the app when new features are available, so you can easily improve and upgrade your bike—all without leaving home.
Where in the world does the tracker work?
Comodules Connectivity Solution tracks your e-bike using satellite positioning, 4G networks, and—where coverage is limited—2G as well. This means you can locate your bike anywhere in the world, whether you’re in Copenhagen or New York.
Unlike Bluetooth® trackers, which only work over short distances, Comodule’s technology provides global coverage and increases your chances of getting your e-bike back if it’s stolen.
How long can I track my bike if it gets stolen?
The device is automatically powered by the bike's main battery and has very low power consumption.
If the bike is stolen, the tracker will continue to charge as long as the main battery remains in the bike and is charged.
If the main battery is removed or runs out of power, the tracker can continue to operate on its own backup battery:
- Up to4 weeks if the bike is not being used.
- Up to1 week, provided the bike is in constant motion.
Note: This feature applies only to the integrated IoT device.
How does the IoT device work?
The IoT solution consists of three components: an IoT device, Christiania Bikes , and a connectivity subscription.
The device is either integrated directly at the factory or retrofitted at the dealer. When you receive your bike, download the app to your phone and connect to the bike via Bluetooth.
When the device is connected for the first time, a unique code is automatically generated between the IoT device and the motor system. This code ensures that the bike can only be unlocked via the app or through our support team.
In the app, you can activate your subscription, which gives you access to tracking and other anti-theft features. When your subscription expires, you can easily renew it directly in the app.
Designed in collaboration with Comodule
In collaboration with Comodule, we have developed an IoT device tailored specifically for our bicycles. This ensures optimal signal reception, high quality, and long-lasting durability.
The device is water- and dust-resistant, discreetly integrated into the bike, and difficult to remove. At the same time, it offers one of the most advanced feature sets on the market.
Powered by Comodule
Comodule is a pioneer and market leader in connectivity solutions for e-bikes and, in just 10 years, has connected more than 750,000 vehicles worldwide.

Why isn't my Guardian IoT device working?
The Guardian IoT device charges automatically via your bike's headlights. Therefore, you must first turn on your bike's headlights for your Guardian device to work.
