Where to Put a Bike GPS Tracker?

As bicycles are very space efficient objects, they don’t leave a lot of room to hide objects. However, there are some smart places you can hide a GPS tracking device on your bike:

Most GPS bicycle trackers have been especially designed to fit in specific areas.

For example, you will find that some fit within the handlebars while others become incognito by doubling up as a bicycle light.

The key to any GPS bike tracker is that it can’t easily be identified and removed by a thief – otherwise they will be able to easily discard the tracker and keep your bike which is hardly a useful anti-theft device.

However, if a bike thief isn’t aware that there isn’t a GPS device on your bike, you will be able to see your bike’s exact location on a mobile app and send a report that the police can instant act upon.

In the rest of this article, we’ll run through nine of the best GPS bicycle tracking devices so you never need to worry about losing your bicycle for good.
