In case of theft, Troja can locate your bike in adaptive intervalls to allow for live tracking over a long duration.

Single Position

You can request the current location of your bike at any time, even when it hasn't been stolen. So you could for example check if your kids made it safely to school.

Motion Sensor

Easily switch on/off the sensor when leaving your bike. You'll be warned via push-notification if your bike moves.

Service center

In case of emergency we can help you get your bike back. If you wish, we can directly interface with the authorities and local police will track your bike.


We work closely with local law enforcement units and insurance companies to provide unmatched service quality.

Private Investigation

About us

In 2012 the brothers Marek and Adrian Rauko started to develop their idea of building their own GPS tracking system from scratch.

Adrian, who worked many years as a private investigator, often had to work with completely unreliable and complicated tracking devices. So one day, during an observation, he had the idea of just taking matters into his own hands and create a device that would finally meet his requirements and that would be easy to use.
That was the time that Marek, a studied electrical engineer and Head of IT at a large technology company, joined him to work together on the development of this tracker.

A few years and many working hours later, Troja for private investigators and public authorities emerged, the currently best non-military grade GPS tracking system available on the market.

This sophisticated technology now serves as base technology for the development of an even smaller tracker for the consumer market, Troja Bike. Adrian and Marek are supported by a large team of hard-working helpers to make this project become reality.
