Handcuff lock for e-scooter: unlike bicycles, e-scooters are difficult to secure with a conventional lock. Our uniquely designed handcuff roller lock solves this problem. With an inner ring diameter of up to 8.5 cm, this secure lock is suitable for e-scooters, bicycles, and other mobility devices. High-hardness material: the e-scooter lock is made of fully alloy steel, hardened to resist cutting, breaking, and sawing. It offers excellent durability, wear resistance, and corrosion resistance. The high-strength chain withstands a tensile force of 10 kN and a shear force of 20 kN. The chain is wrapped in high-quality fabric to reduce noise, prevent scratches, and enhance appearance. Scratch-resistant rubber cover: to protect your mobility device from scratches, a specially designed rubber cover is included. It prevents marks and scratches, increases friction and slip resistance, and improves grip comfort. This makes it an essential e-scooter accessory. Longer and thicker chain: the total length of the lock is 92 cm, with a 60 cm chain section and a chain diameter of 6 mm. The extended and reinforced chain allows versatile use in various environments such as parking lots, backyard fences, and street fixtures. It can be used effectively as a bike lock, motorcycle lock, or scooter lock.
