Frequently Asked Questions (FAQ)

What is the strongest bike lock?

Different bike locks are more secure than others, but the strongest bike lock is one that offers a good locking system. There are so many different bike locks out there, and they all have their different strengths and weaknesses.

Many of these locks are also only effective if they are used properly and correctly. For example, even the best bike chains can be cut with a professional saw, but they have the advantage over other bike locks in that they are easier to take with you when you are riding in less secure locations.
If someone wants to break your bike lock badly enough, they will, but being aware of your surroundings will improve your chances of stopping theft altogether.

Are folding locks any good?

These days, a bike is a cheap second car, a source of weekend entertainment, and one of the easiest ways to get to work. Naturally, most people want to lock their rides up when they leave them parked, leaving them vulnerable to thieves.

At the same time, a bike lock is a considerable expense that most people don't want to deal with. Rather than opting for a small cable to loop around a nearby tree, it can be worth investing in a slightly sturdier folding lock.

This type of lock is simple to use and is compact enough that it's unobtrusive in a busy urban environment. Best of all? A folding lock offers more than enough security against any of the occasional bike thieves that you're likely to encounter.

Is there a bike lock that can not be cut?

There are super-expensive locks and super-strong ones, but any lock is susceptible to a powerful enough pair of bolt cutters.

Solutions like drilling through a thick steel frame or an expensive chain and the locking mechanism can help, but those are parts you might not want to give up.

For the most part, you want heavy-duty bike locks for their deterrence of theft. When it comes to cut-and-run cyclists, it's not worth the time to try and pry apart or saw through your lock or have access to tools that'd allow that in just a couple of minutes.

What is the best U lock?

When you’re traveling, you often need to find a way to lock up your bike. There are a few different things you can do, but the best option is a U lock. These locks work by encircling the front wheel, and the seat, and the rear wheel. If all the components of the bike are locked up, you should hopefully feel secure.

U locks generally come in two designs: threaded and Smart. threaded reduces your options significantly, and only allows you to lock the bike in a U shape. That means that you can keep your bike on the inside of the lock and still have the lock attached to a surface.

Smart locks give you a few more options than threaded locks and tend to be lighter and smaller. That means that they are easy to carry if you’re traveling. They tend to be a bit more expensive, but if you’re traveling, that won’t matter too much.


In conclusion, if you’re going to ride a bike and want to leave it somewhere other than your own home, you will need a lock as well.

But which bike lock do you get? It depends on how important it is to you to have an incredibly secure lock.

If you value ease of use, you may want to go for a lighter lock. But if you value security over all else, you may want to go for a heavier lock. Check our options for folding bike locks in 2022 which will help you take a decision easier.
