U-Lock bike lock ONGUARD Zapięcie U-Lock Neon 10×1200 mm (model 8154YL)

ONGUARD Zapięcie U-Lock Neon is a U-shaped bicycle lock designed to secure bikes and components in urban environments. The lock features a 10 mm hardened steel shackle and an extended 1200 mm length that allows fastening a frame and one or more wheels to stands, racks or other fixed objects. A keyed cylinder provides mechanical key access while the neon-colored finish improves daytime visibility and makes the lock easier to locate.

Advantages

The hardened 10 mm shackle provides resistance against common cutting and levering attempts while the long 1200 mm span enables versatile locking positions, including through the frame and wheel. The keyed cylinder offers reliable mechanical operation and quick locking/unlocking. The neon finish increases visibility in busy or low-light urban settings and helps identify your bike among others. The U-shaped design balances compactness and practical coverage for everyday use.

Suitable for

• Securing bicycles to bike racks, posts, railings and fixed street furniture
• Locking a bike frame together with one wheel
• Short- to medium-term parking in urban areas, campuses and commuter stations
• Use where higher visibility of the lock is desirable for locating or deterring casual thieves

Key specifications

• Shackle diameter: 10 mm hardened steel
• Shackle span/length: 1200 mm
• Lock type: U-lock with keyed cylinder
• Finish: neon color for increased visibility
• Typical use environment: urban and commuter settings

How to use

Position the U-lock so the shackle passes through the bike frame and at least one wheel, then secure it to a solid, immovable object such as a rack or post. Insert the shackle into the keyed cylinder and turn the key to lock; keep the key in a safe place when riding. When unlocking, make sure the locking surfaces are clean of debris before operating the cylinder to ensure smooth key action. Avoid attaching the bike to objects that can be easily cut or lifted.

Usage recommendations

For improved security, use the U-lock in combination with an additional cable or chain to immobilize the second wheel or accessories. Choose well-lit, visible parking locations and secure the lock so it sits off the ground where cutting tools have less leverage.
