Simple bicycle alarm


Posted on Feb 7, 2014

The switch has been mounted inside the tap of the handlebar. I`ve make the battery holder out of an old flashlight. As you can see in the video in step 1, i`ve put the sireen inside the left end-bar grip and the wires pass under the tape and inside the tube where it meets the circuit.
