Project Description

Bicycle chain lock
This lock is a small four-tooth lock. The lock body is made of aluminum alloy and has a cylindrical shape with a diameter of about 25 mm and a length of about 5 cm. The lock core is made of all copper and installed in the central part of the lock body. This kind of lock is connected to a 6 mm thick iron chain on the flat end of the lock body. The entire chain is covered by a plastic hose, and the chain is about one foot and eight inches long. A steel lock cylinder head is connected to the other end of the chain. There is a circular groove around a circle on the lock cylinder head. There is a round hole on the plane at the other end of the lock body, that is, the lock cylinder hole, which just fits the lock cylinder head. There is a lock pin connected to the lock core in this round hole.
Bicycle wire lock
The entire wire rope of this lock is about 1.2 meters. Normally, the steel wire rope can be crimped into a ball naturally. If you need to use it, it can be stretched or rolled into double strands to lock the bicycle. Because of its long wire rope, the bicycle can be locked to the railing post, or several bicycles can be locked together. Therefore, many people like to use this wire lock to lock the bicycle.
