WHAT WE LIKE:
This bike u lock is made of strong carbon structural steel and comes with a silicone cover to resist corrosion. It also has a precise structure to prevent technical opening, making it convenient to use. The larger size makes it suitable for most bikes.
Pros & Cons From Reviewers:
It is easy to steal.
The thief was able to cut the lock quickly.
The rubber coating over the full U-lock and the cable costing both seem pretty robust and so far (I've used it for a few months now) weathers well and is soft enough and thick enough that I never have to worry about it scratching my bike.

How To Choose The Best Bike U-Locks
When it comes to choosing a bike U-lock, there are several factors you need to take into account in order to choose the best one for your needs. The first thing you need to consider is the finish type of the lock. There are several different types of finishes available, including brushed, painted, polished, powder coated, and unfinished. Each type of finish has its own advantages and disadvantages, so you'll need to decide which one is right for you based on your own preferences.
The next thing you need to consider is the type of lock controller. There are several different types of controllers available, including Android, Hand Control, iOS, Push Button, and Ring. Again, each type of controller has its own advantages and disadvantages, so you'll need to decide which one is right for you based on your own preferences.
Once you've decided on the finish type and lock controller that you want, the next step is to choose the size of the lock. U-locks come in a variety of sizes, so it's important to choose one that's big enough to fit around your frame and wheels but not so big that it's cumbersome to carry around.
Finally, once you've chosen the size and style of lock that you want, it's time to decide on a price range. U-locks can vary significantly in price depending on the brand, material, and features they offer, so it's important to set a budget before you start shopping. With these factors in mind, you should be able to find the perfect bike U-lock for your needs.
What To Avoid When Looking For The Best Bike U-Locks
When it comes to choosing the best bike U-lock, there are a few things you'll want to avoid in order to make sure you're getting the most bang for your buck. Here are four things to keep in mind when shopping for a bike U-lock:
1. Don't go for the cheapest option. Just because a lock is cheap doesn't mean it's good quality. In fact, cheaper locks are often made with lower quality materials that are more susceptible to breakage. It's important to find a balance between price and quality when selecting a bike U-lock.
2. Avoid flimsy locks. A good bike U-lock should be made of sturdy materials that can withstand some force. If a lock feels flimsy or weak, it's likely not going to be very effective at deterring thieves.
3. Stay away from complex locking mechanisms. The simpler the better when it comes to locking mechanisms. You don't want to have to fumble with a complex locking system every time you want to lock up your bike. Choose a lock with a straightforward locking mechanism that you can easily use.
4. Don't forget about portability. If you plan on taking your bike with you on public transportation or traveling with it, you'll want to make sure the lock is easy to carry. A bulky or heavy lock can be difficult to transport, so look for something that's lightweight and easy to pack up.
