Many riders have had their bikes stolen, and it's a bummer every time. Luckily for all of us, avoiding bike theft is relatively easy if you plan ahead and think before you leave your bike in a strange place. Keep these elements of safety in mind when you leave your bike exposed, and the chances of your bike being stolen will be greatly reduced.
The first consideration when trying to stop theft is the location of your bike. In general, the more foot or vehicle traffic that passes a given location, and the more well-lit it is, the safer of a place it would be to leave your bike.
