Review on 🔒 High-Quality Bike Chain Lock Motorcycle - Heavy-Duty 3.9ft, 10lbs Lock Combo with 12mm Chain and 16mm Disc Lock Security - Ideal for Bicycles, Mopeds, Scooters, and Motorcycles by Pedro Hague

Very good lock but there is a small inconvenience. The locking mechanism tends to get stuck, but I found an easy fix: you need to make sure the shackle is fully down when unlocking and locking. It seems that an incorrectly installed shackle causes locking and unlocking problems, but it is enough to press it and you will be fine. All in all a great lock to keep people from theft. Recommend using in combination with other anti-theft devices if you plan to use them on more expensive items.
