As attention to the environment and health is rising, attention has been focused on bicycles, and the use of bicycles is gradually increasing. Although the bicycle industry was once classified as a declining industry due to the spread of automobiles, bicycles are being accepted as a new growth engine due to the decrease in petroleum resources, the rise in oil prices, and the global topic of low carbon green growth.

Unlike in the past, bicycles have been diversified, light weight and high gears are being adopted. As a result, expensive bicycles that sell tens of millions of won are sold. Most people who enjoy club activities or mountain bikes purchase bicycles that cost several million won.

The emergence of expensive bicycles raises the issue of bicycle theft. In particular, because there are a lot of people living in apartments, it is difficult to put a large number of bicycles indoors. Keys for restraining the wheels with forks and locks, which are common anti-theft means, have the limit to prevent theft prevention because thieves can use the cutter to dismantle the keys. Another stealing technique involves taking a bicycle filled with keys by means of a truck-like vehicle.

In addition, the risk of theft of bicycles is increasing and the bicycle storage system is on the rise when people place their bicycles (public toilets, urban buildings, etc.) where there are no anti-theft facilities, but the bicycle storage system is increasing. Since it is not possible to further spread the bicycle having an anti-theft function such as the present invention.

Hereinafter, the conventional techniques that have been proposed for the purpose of preventing theft of bicycles will be described.
