Bike Lock Martes Closer — folding/compact bicycle lock, black

Martes Closer — folding/compact bicycle lock in black is a space-saving security solution designed for everyday urban cycling. The lock combines a folding metal construction with a compact profile, enabling convenient mounting on the bike frame or easy storage in a bag. It is intended to provide solid resistance against casual theft and to secure bikes during short stops, commuting and routine parking.

Advantages

The lock’s folding design reduces bulk while maintaining locking length when unfolded, which simplifies handling and transport. Its robust metal segments offer mechanical resistance to common tampering methods, and the compact black finish is low-profile and weather-resistant in normal urban use. The unit is light enough for regular carrying yet rigid enough to deter opportunistic theft attempts.

Suitable for

• Commuter bicycles and city bikes
• Short-term parking during errands or at work
• Mounting on frames with limited space or carrying in bags
• Securing kids’ ride-on accessories and small bicycles

Key specifications

• Type: folding/compact bicycle lock
• Color: black
• Construction: articulated metal segments with a folding hinge design
• Portability: compact profile suitable for frame mounting or bag storage
• Typical use: urban commuting, short stops and bike parking

How to use

Position the lock around the bike frame and a fixed object such as a bike rack or post, then unfold the articulated segments until the lock reaches the required length. Engage the locking mechanism and confirm the lock is securely closed. When not in use, fold the segments back together and secure the lock to the frame mount or place it in a bag for transport. Regularly inspect the lock for wear and ensure the mechanism moves freely.

Usage recommendations

For improved security, lock both the frame and at least one wheel to an immovable object and avoid leaving the bicycle unattended for extended periods in high-risk locations. Store the lock dry when possible and lubricate the hinge and locking mechanism occasionally to maintain smooth operation.
