Arduino Bicycle Alarm and Lights

Step 5 Attach to Bicycle

Attach the alarm anywhere on your bicycle that you want. I chose to mount mine under the seat for a number of reasons. One, it is not as noticeable. Two, it is protected from contact and water. Three, it was out of the way. I attached mine to the bicycle using a few zip ties. This method holds the alarm on, but makes it relatively easy for a thief remove from the bicycle, so be sure to run one of the tamper prevention loops through the frame in such a way it cannot be removed without being cut.

If you have a pouch already attached to the seat post, if you want the alarm more for alert than physical theft prevention, you could consider keeping it in the pouch with one of the tamper prevent loops connected to the bike.
