Bike Lock GERDA Contra 900/5P 90 cm 5 mm black

GERDA Contra 900/5P 90 cm 5 mm black is a flexible cable lock designed to secure bicycles and small personal mobility devices during short stops and everyday urban use. The 90 cm length and 5 mm diameter cable provide enough reach to loop around wheel and frame components and attach to fixed objects such as bike racks or poles. The black finish offers a neutral appearance that fits commuter and casual-cycling styles while the compact, coiled design makes it easy to carry when not in use.

Advantages

The lock combines flexibility and portability, allowing quick fastening and easy storage in backpacks or attached bags. Its construction offers basic theft deterrence for on-street parking and common everyday scenarios. The moderate length accommodates a variety of bicycle frames and anchor points, and the simple design supports straightforward operation without complex mechanisms.

Suitable for

• Commuter bicycles during short stops
• City and hybrid bikes for everyday errands
• Kiddie bikes and children's ride-on accessories
• Securing wheels or frames when combined with a heavier secondary lock
• Attaching scooters or small mobility devices to fixed objects

Key specifications

• Cable length: 90 cm
• Cable diameter: 5 mm
• Color/finish: Black
• Design: Coiled/flexible cable
• Use case: Basic theft deterrence for short-term parking

How to use

Pass the cable through the bicycle frame and at least one wheel, then loop it around a secure, immovable object such as a bike stand or pole and insert the cable end into the lock mechanism. Ensure the lock is positioned to reduce leverage and that the cable is pulled taut to limit movement. For increased security, use this cable lock in combination with a U-lock or chain lock to secure the frame and wheels together. Store the coiled cable in a bag or mount it to the bike when not in use.

Usage recommendations

Use this cable lock primarily for low-risk, short-duration stops in urban areas. For high-risk locations or overnight parking, pair it with a higher-security lock or choose a heavier-duty locking solution. Regularly inspect the cable and locking mechanism for wear or damage and replace the lock if signs of cutting or corrosion appear.
