It is very annoying to have to remove he GPS navigator every time from a bicycle, motorcycle or scooter and then mount it again; in particular when the vehicle is left unattended for just a few minutes. Commercial solutions exist that use a key-system to lock the GPS navigator to the handlebar of a motorcycle, bicycle or scooter but it is fairly easy to create a grab-proof mechanism that might work even better depending upon the circumstances.

Note that what will be presented in this document is not a steal-proof mechanism, but rather a grab-proof, particularly because what is shown should be fairly easy to break using common tools.

The design consists in using some multi-wire steel cable that is undone and only one or two strands are selected. The wire is passed though two holes that are drilled into the GPS navigator on the back. The steel wires are then wound up to create two loops.

Through the two loops, a simple key-lock is added and the wire is passed around the handlebar such that removing the wire would require disassembling the entire scooter.

The steel cable is remarkably strong and it cannot be cut even using typical pliers; as small as it is, it really needs some type of larger sheers. For example, trying to cut through the steel cable with a strong caliper that is meant to cut 10AWG wires, resulted in the caliper itself breaking!

For taking a break without having to constantly take the GPS down, the mechanism seems suitable enough to prevent someone passing by just grabbing the device and running off with it. However, with some tools, the cable can be cut so do not rely on it as an anti-theft device.
