The bicycle lock is designed like this, and the thief collapsed when he saw it
From the moment you own a bicycle, you must know how to prevent theft. In recent years, in order to prevent theft, everyone has racked their brains. Let ’s take a look at the various positions of theft prevention:
With a sturdy lock:
Dozens of locks at the same time:
Lock the frame and wheels:
But in any case, the thief can always find a way to solve these "problems", because the thief will not cause damage to the car during the theft process, they destroy the outside of the car-all kinds of locks. Even if one of the parts of the car is stolen, leaving a rear wheel or frame, the thief will not hesitate to ride anyway after adding other accessories.
Therefore, some people thought that if the frame itself is a lock, and the thief wants to steal the car, it will destroy the car and make it impossible to ride, then there is no sense of theft, and the anti-theft effect is obtained.
In 2014, three university students from Chile took advantage of this idea to create the world's first anti-theft bicycle Yerka, and sold the bicycle to all over the world through the crowdfunding website indiegogo (although it is almost zero profit).
Yerka cleverly uses his structure to lock the bicycle to the pillar.
When we park the car, we can open the rod in the middle of the car body, and then pull up the cushion rod to become the anti-theft rod. Finally, as long as it is engaged, the bicycle can be locked.
The whole journey takes only 15 seconds, which is equivalent to turning the bicycle into a large pliers lock, and can be locked on various bars, and there is no need to prepare additional locks, reducing the burden of riding out.
But at the same time it also caused some doubts:
1. "How to prevent malicious disassembly of wheels?"
——The tire is equipped with a special anti-theft nut, which requires a special key to remove the wheel.
2. "The frame does not look strong at all"
——On the contrary, Yerka is very strong! Look at its performance on the mountain, just like a cross-country bicycle, do you still say that it is not strong:
3. "Guarantee anti-theft and performance"
——Yerka is not only anti-theft, but also has good performance. It is equipped with a three-speed internal transmission, cancels the cable system, and can automatically shift. The change of the three gears is automatically completed according to the speed of the vehicle.
In addition, the internal transmission makes the structure more compact. As far as possible in the design, each part can try to complete multiple functions, eliminating unnecessary parts and links, and improving the reliability of the product. Therefore, compared with the manual transmission, the structure is simple and the dynamic performance is better.
4. "In China, there is no lock that cannot be pried!"
—Sorry, Yerka ’s lock just wo n’t pry. According to the founder, Yerka uses the most advanced locks on the market, and there is no record of thieves successfully prying locks.
5. "I saw off the seat rod directly, install the seat back to the original position, and I can continue riding"
——If the seat rod is sawn off, the disassembled bracket cannot be restored. What the thief got was a bicycle with extremely unstable structure, which might be broken up after riding.
6. "What if I lose my key?"
——The manufacturer has considered this problem. In addition to the traditional unlocking method, (if the funds are sufficient in the later period), you can also use the matching mobile phone APP to unlock Bluetooth.
7. "Not enough telephone poles"
——When there are no telephone poles, you can choose other poles, such as trees. But if there is no rod, or the rod is very short, Yerka's anti-theft function is nowhere to be made. This may be an inherent defect of this bicycle.
Coincidentally, many designers have thought of this idea-turn the bicycle into a lock:
Part of the frame of this bicycle is composed of rigid cables. When you want to stop, you only need to “bind” the end locks to a fixed object. Because if you want to pry the lock, you can only saw off the bicycle frame, and the thief can only get a pile of broken copper.
In general, despite being limited by objective conditions, this idea of turning the bicycle itself into a lock is still very good. After all, no anti-theft method can be foolproof.
The best anti-theft design is not static. Update iteration is the norm.
