OnGuard 5801 U-Lock bicycle lock (ONG-5801)

The OnGuard 5801 U-Lock combines high resistance to manipulation with modern anti-theft security technologies. Designed for maximum durability, it is dedicated to cyclists seeking robust protection for their vehicles both in the city and during longer stops.

Advanced security technologies

The OnGuard ONG-5801 model employs X2P – Double Bolt technology, which enables double locking of the shackle within the lock body, significantly increasing resistance to forced entry. The Z-Cylinder mechanism provides a higher level of protection against drilling and manipulation, effectively preventing unauthorized access to the lock. Thanks to these features, the product stands out from standard U-lock security devices.

Damage-resistant construction and materials

The lock’s construction uses high-hardness steel, which enhances resistance to cutting and overcoming with mechanical tools. An additional vinyl coating protects the bike frame from scratches and reduces the impact of weather conditions on the lock's surface. The entire design is aimed at ensuring maximum durability during everyday use.

User functionality and convenient mounting

The OnGuard ONG-5801 is equipped with a key lock type, which enhances security and prevents accidental opening. The set includes a frame mount, allowing comfortable transportation of the U-lock while riding. The presence of a cable further increases the versatility of the lock, enabling the attachment of not just the frame, but also the wheels or other bike components.
