Bike Cable Lock RockBros 5-digit Combination, 1.8 m Cable, Black

RockBros bike cable lock with a 5-digit combination offers a flexible, keyless solution for securing bicycles and urban transport. The lock uses a 1.8 m steel cable covered in a black protective sheath to reduce the risk of paint damage and surface scratches. The numeric combination mechanism can be set and reset without keys, providing adjustable security for everyday use and short stops in city environments.

Advantages

The 1.8 m cable length provides reach to secure both frame and wheel to a fixed object while remaining compact when coiled. The 5-digit combination increases the number of possible code combinations compared to 3- or 4-digit locks, improving resistance to casual tampering without requiring keys. The protective sheath shields bike paint from abrasion and helps reduce noise when the cable rubs against surfaces. The lock is lightweight and portable for daily commuting and urban use.

Suitable for

• Short stops and daily urban commuting
• Securing frame and one or both wheels to a bike rack or post
• Locking scooters, strollers or other light personal transport
• Temporary security in low- to medium-risk environments

Key specifications

• Cable length: 1.8 m
• Lock type: 5-digit combination
• Cable material: steel core with protective sheath
• Sheath colour: black
• Portable and coiled design for easy storage

How to use

Wrap the cable around the bike frame and a secure anchor point, then thread the cable end into the lock body. Set the correct 5-digit code to engage the locking mechanism. To open, align the digits to your code and pull the cable end free. The combination can be reset by following the manufacturer’s reset procedure: typically set the current code, engage the reset mode on the lock, enter a new 5-digit code, and save the change. Keep the chosen code in a secure place to avoid lockout.

Usage recommendations

For improved security, loop the cable through the frame and at least one wheel and attach to an immovable object. Avoid leaving the bicycle unattended for extended periods in high-risk areas; use this cable lock as a deterrent and for everyday short-term locking rather than as the sole protection in high-theft locations.
