Keltin K02306 is a bicycle chain lock with a key-operated cylinder, designed as a 900 mm long chain with 6 mm thick links.

How to use

Wrap the chain around the bicycle frame and a fixed anchor point such as a rack or pole, ensuring the chain passes through or around non-removable parts of the frame to prevent easy removal. Insert the chain ends into the key lock cylinder and turn the key to secure; keep the spare key in a safe place. When unlocking, insert the key and rotate to release the chain, then stow the chain in a bag or mount for transport. Regularly inspect the chain and cylinder for damage, debris or corrosion and lubricate the lock mechanism as needed according to the manufacturer’s guidance.

Usage recommendations

For improved security, pair the Keltin K02306 chain lock with additional measures such as locking the frame and one wheel, choosing well-lit and visible parking spots, and using a fixed, immovable anchor. Avoid leaving the bicycle unattended for extended periods in high-risk locations.
