🚲 How Do Bike Trackers Work?

🧠 Where does our knowledge come from?

We’ve spent years in the field—recovering stolen bikes, testing trackers under real-world conditions, and refining what works. Our setup isn’t built around a single product or brand; it’s a combination of technologies, working in harmony, tuned for one job: getting your bike back.

We work closely with GPS, beacon, and connectivity suppliers to understand their hardware and make it work for the unique challenges of bike recovery.

🛰️ GPS: Location via satellites

At the heart of most bike trackers is GPS (Global Positioning System). Here’s what that means in practice:

• Your tracker communicates with a network of at least four satellites, calculating its distance from each to triangulate its position.

• The accuracy is typically within 5–10 metres, but urban environments can reduce precision (this is called urban canyoning—tall buildings bounce signals around).

• GPS chips in trackers are designed to wake up, acquire a fix (which takes seconds), transmit data, and go back to sleep to conserve power.

More frequent "pings" = better real-time location tracking, but also more power consumption.

🔊 Bluetooth beacons: Finding bikes indoors

GPS works great outdoors. Indoors? Not so much. That’s where Bluetooth-based proximity beacons come in.

• Beacons emit a short-range radio signal detectable by smartphones or special recovery apps.

• They don't reveal a GPS position—but if your bike is stashed inside a flat, warehouse or garage, our agents can walk around and “sniff” for the signal using a mobile app—like a game of high-tech hot and cold.

• Standard beacons have a range of 20–100m depending on walls and interference. Long-range versions can stretch up to 180m in the open.

Why is this smart? Because a hidden beacon can't be tracked remotely by a thief—but it can be locked onto by someone physically close.

📡 Cell tower communication & triangulation

Most trackers don’t just use GPS. They also include a SIM card or low-power IoT modem to transmit their location over the mobile network.

• If GPS isn’t available (e.g. inside buildings), the tracker can approximate its position using cell tower signals.

• This is known as cell tower triangulation—less accurate than GPS but still useful. Think “block level” instead of “doorstep.”

• Modern trackers use protocols like NB-IoT or 2G/3G to send data with ultra-low power consumption and wide coverage.

This mobile communication is essential for sending GPS locations back to recovery teams—or to an app if your tracker supports it.

🔋 Power, frequency, and battery drain

Here’s the techy part: how do trackers balance signal frequency with power usage?

• Every “ping” (location update) consumes energy: the GPS chip wakes, finds satellites, and transmits data.

• Frequent pings (e.g. every 10 seconds) enable real-time tracking but drain batteries fast.

• Infrequent pings (e.g. every 60 minutes or only on movement) conserve power and extend battery life to months or years.

Modern self-powered trackers use smart power management:

• Motion detection: Only transmit when the bike moves.

• Sleep cycles: Stay dormant when stationary.

• Custom ping settings: Some can adjust the update interval remotely.

Bike trackers combine several location technologies:
