[Super sturdy U-lock] The diameter of the U-lock is about 14 mm (about 22 mm including the cover) and is made of heat-treated hardened alloy steel, making it super sturdy! It has improved strength, hardness, impact resistance, abrasion resistance, corrosion resistance, and durability! In addition, the zinc alloy lock cylinder has high strength and hardness, greatly improving theft prevention! The bicycle lock is difficult to cut, and cannot be cut with a grinder! It is resistant to 12-ton rebar cutters, hammers, and electric drills. Prevent theft with this thick and sturdy lock when parking your bike for long periods of time or storing it outdoors! [Improved security] A 120cm security cable is included, so you can use it in combination with a U-lock to easily lock the bike with an earth lock, and you can lock multiple bikes at the same time! A high-security wave key is also included, and since it has a special groove, it cannot be easily unlocked with any other key, which effectively reduces the rate of malicious unlocking. Three keys are provided, so you don't have to worry about losing the key. The bike lock is a type that locks and unlocks at both ends, making it difficult to pick and providing high security. [With silicone cover] The bike lock is covered with a silicone cover, so it feels good to the touch and does not deteriorate due to metal wear. You can rest assured that the handle will not be damaged even if you hang it on the handle while moving, and that your precious bike will not be damaged. (Because the key body is heavy, please be careful not to hit the body of the bike.) In addition, since there is a silicone cover in winter, you can avoid the prickly feeling caused by the cold even if you open and close the key with your bare hands. [Easy to carry] This lock is very sturdy and a little heavy, but it comes with a dedicated bracket for mounting on the bike, so you can attach it to the seat post of your bike and carry it around easily when you're on the move! It can be used on a variety of bikes, including road bikes, cross bikes, and MTBs, as well as motorcycles, electric bikes, doors, and more.
