Systems, methods, and devices are provided to sense unauthorized use of a vehicle. For example, an electronic device may include sensors to detect an operational parameter of a bicycle and communications circuitry to couple the electronic device to a second electronic device associated with user of the bicycle according to authorization information. Control circuitry may determine when the bicycle is in operation based at least in part on the detected operational parameter, identify whether the second electronic device is substantially within a communicative proximity of the electronic device when the bicycle is in operation, and generate an alert indicating unauthorized operation when the second electronic device is not identified as substantially within the communicative proximity of the electronic device. |
