And like many of its peers, it is designed with the latest deadbolt locking technology that increases the holding power of the lock giving you the ultimate peace of mind.



The U-lock type of bike lock is probably the best form of deterrent. This is because it is relatively small and therefore offers a smaller surface area for a thief willing to insert a hammer or any tool to pop it apart. It consists of a U-shaped shackle that locks into a disc-style cylinder and can only be unlocked with the help of a key. This type of bike lock comes in varying sizes. Typical usage includes locking one wheel of the bike with the frame to a fixed object, say, a tree or a metal bar.


Cable locks are usually versatile and much more flexible but offer less protection than U-locks. This is because they provide a greater surface area for a thief to easily cut the cable. They are better used in combination with U-locks, especially in high-risk areas. However, on their own, they are better used to secure movable parts of the bike like the wheels and seats in low crime areas. They come in different sizes and shapes and some are even covered in unique materials with different colors.


Chain locks are probably your best bet as they combine the efficiency of the U-lock and the cable lock. They are made of a chain link that locks into a padlock or a base lock attached to the chain. The chain is usually sturdy enough to resist any cutting attempt be it with a hacksaw or a chisel. However, it is imperative that you invest in an equally thick padlock that can resist cutting for greater efficiency.



The first thing you need to consider when choosing a bike lock is the strength of the lock. As earlier discussed, some locks are much stronger than others in terms of material and component. When you are considering the strength, it is best to go for the U-locks as these are usually stronger and difficult to cut through.


As far as the efficiency is concerned, you need to go for the chain locks. This is because the chain locks combine the efficiency of the U-locks and the Cable locks in terms of strength and ease of use. The cable locks are more flexible than the U-locks while the U-locks are much stronger than the cable locks. Therefore the choice of which lock to go for will depend on your individual needs.
