U-locks (also known as d-locks) are kind of like giant padlocks that attach to your bike and anything you want to secure. The special feature of the u-lock is that it is enough to prevent your bike from being stolen! Portable and easy to install on your bike and anywhere you want to lock down. There are 3 steps to tell you how to choose the best u-lock for you:

Step 1: choose the right level of security

Step 2: choose the right size u-lock

Step 3: choose the right u-lock for your budget

Step 1: choose the right level of security introduce.

The easiest way to judge the safety of a bicycle lock is to look at the ratings of the testing agencies Sold Secure and ART. Both groups test and rate a large number of locks based on their security level. Sold Secure uses a bronze, silver and gold rating system (gold is obviously the safest). While ART uses a star system, the lock level is between 1 and 5 stars (5 stars is the safest).

Step 2: choose the right size u-lock introduce.

There are many factors that determine which size U-lock you should choose, including whether it is a main lock or a secondary lock, how you will carry it, the type of bicycle you ride, and where you usually put it. The master lock is responsible for ensuring that your photo frame has not been stolen. Therefore, it usually needs to be large enough to get around your frame, a wheel, and whatever objects you lock the bike to. The secondary lock is only responsible for ensuring that the other wheel has not been stolen. Since it only needs to go around a wheel and a stationary object or a wheel and a frame, it can be significantly smaller.

Step 3: choose the right u-lock for your budget introduce.

So you know what security level you need and how to judge the different protection levels within that level. I hope you know the size of the U-lock that fits your bicycle type, the location of the lock, how to carry the lock, and how to use it.
