Bicycle Lock rock machine SK.Lock 10.180 — folding bike lock, Black Grey

rock machine SK.Lock 10.180 is a compact folding-style bicycle chain lock in black and grey with a 10 mm thick chain and 180 cm length. Supplied with two keys—one of which has an integrated LED light—the lock weighs 430 g and is intended for everyday use and urban commuting where a portable, sturdy locking solution is required.

Advantages

The 10 mm chain thickness and 180 cm length provide a balance of rigidity and reach for securing a bicycle to fixed objects. Two keys are included for convenience, and the LED-equipped key helps with alignment in low-light conditions. At 430 g the lock is designed to be easy to carry while offering durable protection; the black and grey finish gives a neutral appearance that fits most bike styles.

Suitable for

• Securing bicycle frames to racks or fixed posts
• Locking wheels together with the frame to deter opportunistic theft
• Everyday urban commuting and short-term parking

Key specifications

• Thickness: 10 mm
• Length: 180 cm
• Keys: 2 (one key with LED light)
• Weight: 430 g
• Color: black / grey

How to use

Wrap or fold the chain around the bicycle frame and a fixed object, then insert the chain end into the locking mechanism and turn the key to lock. Use the second key as a spare and switch on the LED light of the illuminated key in low visibility to help align the key with the lock cylinder. Keep the keys stored separately when possible to reduce the chance of losing both at once.

Usage recommendations

Attach the chain to both the frame and a wheel where feasible, choose well-lit and busy parking locations, and avoid leaving the bicycle unattended for long periods in high-risk areas.
