If you are concerned about your bike and want to make sure it stays where you left it, consider getting a bike alarm. No alarm system is perfect and if a thief really wants your bike, they are going to get it. But an alarm system used with other security steps, such as covering your bike, locking the handlebars, using a wheel lock and chaining up your bike, can make it less appealing. 

Most alarms have motions detecters that will sound  when the bike is bumped or moved. Some wheel locks also have alarms and will sound if the tired is rolled. In most cases this is enough to cause a would be thief to move on.

If you ride in a high theft area they can be a good investment. They are on all the time so if you get one, make sure you keep the battery on a trickle charger when you are not riding.
