Bicycle locks

Buying advice for: Bicycle locks

• Types of bike lock

  There are different types of bike locks that offer different levels of security and application options. U-locks, also known as U-locks, are very popular due to their robustness and high level of security. They consist of a solid metal shackle that engages in a locking mechanism. Chain locks consist of hardened steel chains that are protected by a plastic or fabric cover and can be flexibly placed around frames and fixed objects. Folding locks are a relatively new invention and combine the flexibility of chain locks with the compactness of U-locks. They consist of rigid metal links connected by hinges. Cable locks offer a high degree of flexibility and are easy to transport, but they offer less security and are better suited as an additional lock. Frame locks, which are mounted directly on the bicycle frame, offer an easy way to lock the rear wheel and prevent it from being ridden away.

• Bike lock brands

  There are numerous renowned brands that specialise in the manufacture of bike locks. ABUS is one of the best-known brands and stands for high security standards and innovative technologies. Kryptonite is also a leader in the bicycle lock sector and is known for its strong U-locks and extensive security guarantees. Trelock offers a wide range of security solutions, from robust chain locks to intelligent folding locks. OnGuard offers high quality locks at affordable prices and is known for its practical and secure designs. Knog, originally known for its lighting systems, has also made a name for itself with stylish and functional bike locks.

• Materials and workmanship

  The materials and workmanship of a bike lock are decisive for its security and durability. High-quality locks are made of hardened steel that is difficult to saw through or crack. U-locks and chain locks often use this hardened steel, sometimes with additional coatings to increase resistance to bolt cutters and saws. Plastic or textile covers around the chains prevent damage to the bike frame and increase comfort during handling. The locking mechanisms themselves are often made of robust materials such as stainless steel and are secured against picking and drilling. Good workmanship ensures that the lock works reliably even with frequent use and is not affected by wear and tear.

• Technical features

  Modern bike locks offer a variety of technical features that increase security and user-friendliness. Some U-locks and chain locks are equipped with alarm functions that emit a loud sound in the event of attempted tampering to deter thieves. Many locks have high-security locking cylinders that are resistant to picking and other break-in methods. Models with an integrated LED light make it easier to open and close the lock in the dark. Electronic bike locks, which can be controlled via Bluetooth or an app, offer additional security functions such as theft notifications and location tracking. Some of these smart locks also allow access codes to be shared with friends or family members, which makes everyday use easier.
