How does the GPS tracker function?

A tracker is used to determine and monitor the exact location of something. The GPS device contains a component that collects signals and calculates the coordinates of the device which needs to be located. These coordinates are transmitted by mobile telephony, Wi-Fi or radio frequencies through the Internet. The GPS system functions by providing precise information, such as the exact location of a vehicle or person. Harnessing this technology, the business PowUnity developed a special GPS tracker that can track the location and route of a bike across Europe using real-time tracking in the app. In addition, the tracker charges itself while riding the e-bike. The GPS tracker costs € 199.99 (excl. annual fee of € 39.50) and is available for the following motors: Bosch, Brose and Shimano.

Features your GPS tracker needs to have

  • You should be able to hide your tracker somewhere “inside” the bike, so that the thief does not discover your device. A GPS signal can be disrupted substantially due to weather conditions or metal. That said, you need to ensure that the signal is degraded as little as possible.
  • You probably already know this from your own smartphone: As soon as you activate the GPS signal, your smartphone eats up the battery in no time. That’s why a long battery life is essential for a good GPS tracker.
  • You should also ensure that the app that comes with the GPS tracker works well on your smartphone.


Standby Mode

High-quality GPS trackers have a motion sensor that automatically switches the bike GPS to standby mode. The bike tracker will go into standby if:

  • the motion sensor does not detect any movement.
  • no further coordinates for tracking are received, stored or transmitted. This is also unnecessary since it means the bike is not moving.

In standby mode, GPS trackers only need 2 mA of current!
This is very sparing on the battery and increases battery life substantially. At that point, the device is only “woken up” if the motion sensor detects that the bicycle has been moved again.

Transmission interval of the GPS tracker

In addition to a battery life that is as long as possible, the transmission interval is also crucial. Keep a close eye on two important factors:

  • A tracker that sends a signal every 4 minutes uses a lot less energy than a GPS tracker that communicates its location every 10 seconds.
  • However, if you want to be alerted to a bike theft, a 10-second interval is extremely significant.

Short and sweet: The combination of long battery life and the optimal transmission interval are the key to success.

In addition to locating the bicycle, an alarm that goes off whenever the bike is moved without permission is the most important function of a GPS tracker. If you wish to take advantage of this alarm function on your tracker, you will have to remember to activate it using the app on your mobile phone. At that point, the minute somebody moves your bicycle, it will set off an acoustical and visual alarm.
For this function, a motion sensor is also required.

Thanks to this GPS tracker from PowUnity, even the most refined bicycle thieves no longer stand a chance and you can park your bike in a public space without any further concerns.
