How to choose a bicycle lock
During the investigation, many bicycle storage areas were found using inexpensive crucible key locks. After hearing the reporter’s experimental results, several citizens raised concerns: “If this type of lock is so unsafe, what kind of lock should we use for our bikes?â€
To address this issue, Director Wang Xiangming offered some practical advice on choosing a reliable bike lock. He recommended purchasing from formal stores rather than street vendors, as these tend to offer better quality. While basic locks may cost around 40 or 50 yuan, he suggested opting for ones priced over 60 or 70 yuan for improved security. Additionally, he advised checking the weight of the lock — generally, the heavier it is, the more secure it tends to be. When buying, he also recommended asking the seller to demonstrate the lock’s strength by performing an on-the-spot test.
The reporter then tested various types of bike locks, ranging from the cheapest to the most expensive.
1. **Bike-issued Lock**
This is a very simple lock that can be opened in just a few attempts. It’s too thin and not safe at all.
2. **Horseshoe Lock**
A circular lock that wraps around the wheel. However, most of them have weak cylinders that can be easily broken.
3. **Iron Chain Lock**
Though it looks strong, it can be cut with pliers. A single-link chain is particularly vulnerable, while a thicker wire-twisted chain offers slightly better protection.
4. **U-Lock**
These are much stronger than chain locks, provided they are not cheaply made. A fixed U-lock secures the bike at two points, making it harder to steal. However, the junction where the U-shape meets the bar is often the weakest point, as it can be cut with pliers. Two-point fixed U-locks are more secure.
5. **Idling Lock**
This type has a cylinder that can rotate freely, making it resistant to forced entry. It is considered one of the best options on the market, though it comes at a higher price.
Choosing the right bike lock is essential for protecting your property. Always prioritize quality, weight, and real-world testing when making a purchase.
