A quiet revolution within the frame is transforming the world of two-wheelers: Internet of Things (IoT) modules are turning pedelecs into connected, adaptive vehicles. The Estonian company Comodule has now developed such a control unit in a mini format.
Our verdict on the Comodule Astra
Smart modules such as the Comodule Astra form the digital nervous system of modern e-bikes. Not only do they provide effective protection against theft, but they also ensure that the bike remains up to date for years to come through regular updates. Comodule thus offers a connectivity system for manufacturers who do not rely on complete system providers such as Bosch or Avinox.
The Estonian company Comodule has developed its new IoT module, Astra, a tiny control unit that is securely mounted within the frame and connected directly to the e-bike’s battery and data cables (CAN bus). The term ‘IoT’ refers to the digital connectivity of objects to the internet. Using mobile networks, Bluetooth and GPS, the Astra module maintains constant contact with a cloud and the rider’s smartphone app.
An overview of the key features
- Precise location tracking (Wi-Fi Location): If the GPS signal is lost in underground car parks or dense urban canyons, Astra uses nearby Wi-Fi signals to determine your exact location.
- Active anti-theft protection: If the parked bike is moved, the app triggers an alarm. The motor assistance can be deactivated remotely via a digital immobiliser (Drive Unit Immobiliser).
- Long-lasting buffer battery: Even if thieves remove the main battery, the module switches to an internal battery and remains traceable for up to 12 months.
Can the module be retrofitted?
Astra is not an off-the-shelf retrofit kit intended for self-installation by end users. As the module interferes deeply with the on-board electronics and incorrect installation may invalidate the warranty, Comodule is aimed at bicycle manufacturers (OEMs) and specialist retailers.
Nevertheless, motorcyclists do have the option of retrofitting the system: many manufacturers design their models to be ‘IoT-ready’. In this case, an authorised dealer can fit the Astra module as an accessory or retrofit, wire it up and activate it in the engine software.
Who benefits from it?
To enable motor software or battery control systems to be updated remotely (over-the-air updates), the bike requires a control unit with a mobile network connection. Some motors or e-bike systems (Bosch, Avinox, Specialized, etc.) come fitted as standard with their own mobile network or Bluetooth modules and offer the features described (OTA updates, app connectivity, and in some cases also tracking and motor lock) within their own ecosystem. This raises the question: who actually benefits from such a module? The answer: The e-bike market is extremely fragmented, and not every manufacturer is a giant like Bosch or DJI. Alongside the industry giants, there are numerous smaller drive system and complete bike manufacturers who have neither the money nor the resources to develop their own IoT hardware, programme apps or set up global server infrastructures for over-the-air updates. They can use the Comodule Astra as a white-label modular system.
