How to use

Place the lock around the bicycle frame and a fixed object such as a bike rack or pole so that both the frame and at least one wheel are secured when possible. Engage the locking mechanism according to the lock’s design, ensuring the closure is fully seated and the key or combination is removed.

Use this compact lock as a convenient, portable option for short stops and low-risk environments. For longer parking periods or higher-risk locations, combine it with a heavier-duty lock or choose a more robust security solution to improve protection. Regularly inspect the lock for wear and keep moving parts lubricated to ensure smooth operation.
