Poussé par des facteurs tels que la sensibilisation accrue des utilisateurs à la santé, the rise of cycling competitions, growing environmental demands, and the need to alleviate traffic congestion, the bicycle market is expected to continue expanding.
Bicycle safety has always been a core concern for users. Antivols en U, which are resistant to prying, cutting, and sawing, are widely popular in the market.

The anti-theft performance of a U-lock is determined by three core components: the lock beam, the lock cylinder, and the lock body. Their materials, manufacturing processes, and structural design directly affect protection level.
It is recommended that buyers purchase high-security bicycle U-locks, focusing on these three key dimensions for rigorous evaluation. Accurately score the locks to ensure you choose the right one, the best one, and peace of mind.
What specific aspects should be reviewed? Below, we will explain in detail using the MAKE’s MK625 bicycle U-lock as an example.
This lock is made of zinc alloy and iron, making it sturdy and robust, effectively resisting violent damage such as knocking, prying, and smashing by thieves, providing a solid foundation for vehicle security.

Lock Beam
A 14.5mm solid lock beam with a compact, cavity-free structure and thick material, offering significantly greater strength than hollow designs. Its diameter is equivalent to an AA battery, providing excellent resistance to hydraulic shearing.
Lock Cylinder
A five-digit combination lock cylinder with 100,000 possible combination combinations, resulting in a low false opening rate and making it more difficult to crack than a four-digit combination lock.

Users can change the combination at any time, further enhancing lock security.
Lock Body
The latch inside the lock body precisely engages with the lock beam’s groove; both latches must be opened simultaneously to unlock.

The latch is robust and sturdy, not easily loosened, and offers strong pry resistance.
The lock body surface is protected by a silicone protective sleeve, providing rust and wear resistance for long-term vehicle protection.
En résumé, the MK625 bicycle U-lock offers excellent anti-theft performance, is durable, and a reliable purchase.
