ONGUARD Heavy Duty Link Plate Foldable Bike Lock K9 model 8114 100 cm 5 keys with code

ONGUARD Heavy Duty Link Plate Foldable Bike Lock K9 model 8114 is a 100 cm folding security lock designed to secure bicycles, e-bikes and scooters in urban and transit environments. The lock uses a link-plate folding construction that combines hardened steel plates and articulated joints to provide a compact folded size and extended reach when deployed. Supplied with five keys and an encoded key system, the lock offers key redundancy and consistent keying for everyday use.

Advantages

The link-plate folding design balances portability and security: it folds down for easy storage on a frame or in a bag and unfolds to wrap around a variety of fixed objects. Hardened steel plates and reinforced pivot points increase resistance to cutting and leverage attacks compared with simple cable locks. The included encoded key system provides spare keys and reduces the risk of key duplication by casual observers. At 100 cm length the lock accommodates larger frames, through-rail attachment and combined locking of bike frame and wheel.

Suitable for

• Securing city bicycles and commuter e-bikes
• Locking scooters and shared mobility devices
• Temporary parking at transit hubs, bike racks and public racks
• Situations where a compact, portable lock is preferred over a bulky chain

Key specifications

• Folding link-plate construction for compact storage and extended reach
• Overall length: 100 cm when unfolded
• Hardened steel link plates and reinforced joints for cut and leverage resistance
• Keyed locking mechanism with encoded key system
• Five metal keys supplied
• Protective coating on plates to reduce paint damage to frames

How to use

Unfold the link plates and wrap the lock around the bicycle frame and a secure anchor such as a fixed post, rack or immovable structure. Position the plates to minimise leverage points and close the locking mechanism until it clicks or locks according to the key system. Keep spare keys in a secure location and avoid forcing the lock open with excessive torque. Fold the lock back down for transportation when not in use and secure it to the frame or carry it in a bag using the compact folded shape.

Usage recommendations

For improved security, use the lock to secure both the frame and at least one wheel to an immovable anchor. Combine with an additional short cable or secondary lock for quick-release components. Store spare keys separately and periodically inspect the joints, coating and lock cylinder for wear or corrosion, especially after exposure to road salt or coastal environments.
