GPS stands for Global Positioning System. To determine the position of an object (e.g. a bike), a transmitter and a receiver are needed. The transmitter is a satellite system in space. The receiver is a GPS tracker located on earth.
GPS satellites continuously transmit their position via radio signals. The GPS tracker on Earth receives these radio signals and converts them into its own position data. If the GPS module is located in a bicycle or e-bike, for example, then the accurate GPS location can be transmitted to the owner’s smartphone so that he or she can see the last location coordinates of his or her bike in real time (active gps tracking).
The transmission of the GPS bike trackers’ position data to a terminal device (e.g. smartphone) takes place via radio (e.g. 2G, 4G) and an intermediary server.
BikeTrax from PowUnity is a GPS tracker based on 2G technology. 2G has the largest and most stable network coverage and is currently the best solution for tracking bikes and e-bikes.
The 2nd generation mobile network (2G) will be gradually switched off in Europe at the beginning of 2023. To ensure that your GPS anti theft device can continue to transmit seamlessly, we have developed a new BikeTrax generation based on the 4G network. If the 2G GPS tracker can no longer transmit in your country, we will send you a new BikeTrax 4G GPS tracker in good time. The connection cable remains the same.
The GPS tracker contains an M2M SIM card from the telecommunications company Magenta. The GPS tracker is optimised for their SIM card to ensure ideal reception and data usage to show you the bike’s exact location. The integrated SIM card protects you from data transmission fees abroad (roaming). In addition, a dipped rubber coating ensures that the bike gps trackers are 100% water- and dustproof. This means that it is no longer possible to replace the SIM card at a later date.
Each GPS tracker e-bike set comes to you with the following components:
- GPS bike tracker with integrated SIM card
- Connection cable compatible with your e-bike motor
- GPS tracker additional battery with a capacity of 1,000 mAh
- Double-sided mounting tape for secure GPS tracker connection
- Suitable cable ties for fixing the connection cables
- Free smartphone app for iOS & Android
The bike tracker additional battery ensures that the GPS Tracker transmits or receives even when the power supply (e-bike battery) is switched off or removed. It has a long battery life and lasts for a further 14 hours if the e-bike is moved continuously and up to three more weeks on stand-by.
The mounting depends on your e-bike motor. First select the right GPS tracking device for your e-bike motor and PowUnity will send you the appropriate connection cable and simple, self-explanatory installation instructions together with the GPS tracker so you can start to monitor GPS tracking right away.
To use the bike theft protection via GPS and connect it to your mobile device, download the PowUnity smartphone app from the App Store or Google Play. In the app you can register your BikeTrax with an email/password combination and your individual BikeTrax ID (included in the BikeTrax package). You can use the PowUnity app also on the PowUnity GPS tracker web platform on tablets or laptops.
On some bikes, the cable cover of the motor housing completely encloses the pedal crank.

In this case, the pedal crank (2) must be removed before opening the cable cover (1) of your Bosch motor. You therefore need a crank puller (3) to install your Bosch bike GPS tracker. If this is the case with your e-bike Bosch motor, then you can order the e-bike crank puller directly via the above selection. Apart from that, you do not need any special tools.
In most cases, you only need a different connection cable if you want to install it in another e-bike (with a different motor). You can purchase the connection cable afterwards from PowUnity. Only in exceptional cases does the complete bike tracker have to be replaced when changing the motor or e-bike.
