Bicycle lock Sourcing FSBYL48523 — joint lock, 22 x 1000 mm

Sourcing Bicycle joint lock model FSBYL48523 is a folding-style security device with articulated steel links and compact dimensions of 22 x 1000 mm. Designed to secure a bicycle frame and one wheel, this joint lock folds into a transportable form and includes an integrated mounting bracket for attaching to frames during rides. Its construction balances portability and protection for everyday urban usage, offering a practical solution for short stops, commuting and storage at home or at work.

Advantages

The folding articulated design provides a compact profile when stored and sufficient length when deployed to wrap around a frame and a fixed object. Hardened steel links increase resistance to cutting tools compared to basic cable locks while the included mounting bracket allows easy transport without needing a separate bag. The lock’s geometry and jointed segments enable secure positioning around irregular objects and tighter fit on smaller frames typical for children’s bikes.

Suitable for

• Securing children's and small adult bicycles in urban environments
• Short stops during commuting, errands or school runs
• Home or workplace storage where moderate security is sufficient

Key specifications

• Type: joint / folding bicycle lock
• Material: articulated steel links with protective coating
• Dimensions: 22 x 1000 mm (compact folded length and extended wrapping length)
• Locking mechanism: integrated cylinder lock
• Accessories: integrated mounting bracket for frame attachment

How to use

Unfold the joint lock and position it so it passes through the bicycle frame and at least one wheel, then loop it around a fixed, immovable object. Insert the locking end into the cylinder and turn the key to secure. Use the mounting bracket to carry the folded lock on the frame during transit; ensure the bracket is tightly fixed and the lock is folded to minimize movement. Keep keys in a safe place and avoid forcing the mechanism if it resists turning.

Usage recommendations

For improved security, combine the folding lock with an additional cable or small chain to immobilize both wheels or accessories. Choose well-lit, visible locations and attach the lock through the frame tube rather than only the wheel spokes to reduce theft risk. Regularly inspect the locking cylinder and moving joints for dirt or corrosion and apply a small amount of suitable lubricant if movement becomes stiff.
