After investing hundreds of dollars on your bike – its security is your next priority. Finding a good quality bike lock can sometimes be tricky. The best bike lock should be strong and secure enough to hold your bike and be convenient enough for you to use anywhere. Additionally, the bike lock should also be designed to anticipate different antics that thieves may use to penetrate it and be able to counter them.

Well, you don’t have to worry about going in circles trying to find the ideal lock for your bike. Below we’ve compiled the list of the 10 best bike locks in 2020. So your only job is to pick one that closely matches your needs.

How To Choose A Bike Lock – Buying Guide



A keyed mechanism locks bicycles using keys. You will come across bike locks that use keys or combinations (4 to 5 digit passcode operated) when you are choosing the best lock for bikes. Keyed locks use flat keys or cylindrical keys. Flat keys tend to be favored as they are more difficult to pick.

Additionally, many keyed bike locks come with at least two keys so you can use one daily and store the other as a spare. Other manufacturers even provide a service whereby you can order a replacement key in case you lose yours.


You will find a shackle on U style locks. The shackle is the U shaped part of the lock that connects to the deadbolt to secure the lock. Some bike locks are designed with shackles that lock in on both ends whilst other bolts lock in on one end for secure holding power. 

Lock Mechanism 

The best lock for bikes must be supported by a mechanism that easily locks bikes. If you use a U-lock, its mechanism is run by moving the shackles towards the deadbolt which holds them in place. Chain and cable locks use a key or combination lock to hold them in place. A wheel lock clasps the wheel (normally the rear wheel) to immobilize it as the lock cable or chain passes through the spikes.


When you are exploring the best way to lock a bike, you will come across several lock types. The type of bike lock you go for will affect the security of your bike. The common ones are the U-lock, chain, cable, and wheel locks. 


The U-lock is the most secure locking mechanism as it has minimal space to insert a crowbar or other attacking tools. It also features a bulky locking mechanism that helps to protect against attacks from hammers or bolt cutters. These bike lock types are favored for use in the city and high crime areas.

Cable And Chain Locks

Cable and chain locks sometimes appear to be similar. Cable locks boast a coiled wire covered with vinyl or PVC and bound to an in-built padlock or combination lock. Chain locks on the other end boast steel links covered with nylon, vinyl, or fabric cloth.

Although they are not as secure as U-locks, they are still favored for their versatility as they can be used in a cross section of outdoor and sports equipment. It all depends on the length of the chain or cable. Chain and cable lock types can be used in areas of low to high risk of theft.

Wheel Locks

Wheel locks are normally mounted on wheels or seat posts.  On the wheels, the locks come in an O-style lock that is not attached to any fixed object or a larger chain-like lock that can be attached to a fixed object. These lock types are convenient however, their quick release and convenient design, unfortunately, make it easier for thieves to circumvent them. So, they may not be the best option for areas that are prevalent in crime.


The best lock for bikes should also be well protected to enhance its durability. You don’t want to invest in a lock that will be damaged in a short period. Many good quality bike locks feature a coating or covering to protect it from scratches, rust, water, and direct sunlight. 

Common protection for bike locks you will find includes plastic coating as well as fabric, vinyl, or PVC coverings – depending on the type of bike lock it is.


Many of the best bike locks are made from steel and other variations of steel alloys such as chromed or manganese steel. These materials are favored for their sturdy build and resistance. When they are used to make bike locks, it is difficult to cut through them with attacking tools.

You will notice that different locks have different widths, the wide the diameter, the more difficult it is to cut through the material.  However, when you are choosing the ideal width for your bike locks, you must also think of your bike’s design and ensure that the lock will properly fit.



Q: Is There A Bike Lock That Can't Be Cut?

Q: What Is The Hardest Bike Lock To Break?

Q: Are U Locks Better Than Cable Locks?

Q: How Many Locks Do I Need?


It depends on the safety of the location you plan to leave the bike and how you lock it. In general, a single lock to secure your bike frame is enough. However, if you want to add security, then, you will need two bike locks – one to secure your bike frame and the other to secure the wheel.
