Lock rock machine One SK.Lock 10.120 by rock machine — compact folding bicycle lock, black/grey

The Lock rock machine One SK.Lock 10.120 by rock machine is a compact folding bicycle lock in black and grey designed for everyday urban use. Its folding construction reduces storage volume while providing rigid links that secure frames and wheels. The lock is lightweight and shaped to fit conveniently on backpacks, inside panniers, or on dedicated mounts, offering a balance between portability and protection for short to medium duration parking.

Advantages

The folding mechanism allows the lock to collapse into a compact package for easy transport without exposed loose parts. Hardened steel links resist cutting and leverage attempts more effectively than cable-style locks, while the articulated joints enable flexible positioning around frames, wheels, or fixed objects. The lock’s finishing in black and grey reduces visible wear and integrates unobtrusively with most bicycles and scooters.

Suitable for

• Securing city bicycles during short stops
• Locking scooters or e-bikes in urban environments
• Use with bicycle racks, poles, and railings
• Transport in backpacks, saddlebags, or on-frame mounts

Key specifications

• Design: folding articulated lock for compact storage
• Material: hardened steel links with protective coating
• Colors: black and grey finish
• Weight: lightweight construction suitable for daily carry
• Locking mechanism: cylinder lock with key operation
• Fit: suitable for securing frames and wheels to fixed objects

How to use

Position the lock so the folded links wrap around the bicycle frame and a fixed anchor point such as a pole or rack. Extend the articulated segments as needed to pass through the frame and at least one wheel, then align the ends and insert the locking cylinder until it engages. Close the lock and remove the key. When not in use, fold the segments back together and stow the lock in a bag or mount. Regularly check the cylinder and joints for dirt and moveable debris to ensure smooth operation.

Usage recommendations

For improved security, use the folding lock in combination with an additional wheel or frame lock when leaving the bicycle unattended for extended periods or in high-risk areas. Store the key in a secure place and inspect protective coatings for damage after exposure to harsh weather.
