With push bikes costing anywhere up to $20,000 for a high-end road bike, you are going to want to make sure they are safe and secure when you leave them unattended. So how do you do that? With a great, highly secure bike lock of course!
There are lots of different types of locks to choose from so what style is going to suit you? We have selected the top 10 best bike locks we have found for sale in 2020 and reviewed each of them so that you can get the low down on each product.
There are a few different types of locks that we have on our list. These include:
A U Lock:
The U lock (also known as a D lock) is a lock that is rigid in shape. You hook the U around your bike frame and lock it into place with the end bolts. These bolts usually have deadbolts, pry protection, and anti-drilling protection within them to keep any thieves from attacking your setup.
A Cable Lock:
A cable lock is a lock that uses a cord of steel cable to wrap around your bike and locks into either a key-operated bolt or a combination lock. These cable locks mean you can wrap the cable around your bike and around your wheels as well.
This means more of your bike is secure against theft, although thieves do target cable locks more than U locks because of their flexibility.
A Chain Lock:
A Chain lock is similar to the cable lock except the cable is replaced with a heavy-duty steel chain. This chain is usually quite thick which makes it quite heavy. This weight alone will deter thieves, but it also means that you have to carry the weighty lock around with you.
Overall there are lots of different types of locks with different kinds of functions, but which one will suit your needs best? Here is a brief summary of all the locks in our top 10 list.

1. Kryptonite Heavy Duty U Lock – Best Overall
Kryptonite is one of the biggest names in bike locks and they are renowned for their high-security measures. The Heavy Duty U Lock does not disappoint and is by far our best overall bike lock available for sale in 2020.
This bright yellow lock is made from hardened steel and is resistant to all hand tools such as bolt cutters and saws. No matter how persistent the thief, they are not likely to get through the Kryptonite U Lock.
The locking dimensions are 4 inches by 10.25 inches and should fit your bike nicely. It comes with two keys (although Kryptonite will replace the keys globally should you lose them) and has an anti-theft protection offer of up to $4000 because they are so confident that no one will get through the lock.
Overall this is the best bike lock you are going to buy this year.

- Comes with 2 keys
- Anti-theft warrant of $4000

2. DINOKA U Bike Lock – Runner Up
This heavy-duty lock is our runner-up because while it is still durable, it also comes with a 4ft steel cable making locking your bike up more flexible. If you aren’t using a traditional bike stand or bike park, then the DINOKA is a good investment.
It comes with a larger U bracket which is situated underneath your saddle. Then, you simply loop the steel cable through this and onto something sturdy. You can also loop the cable through the bike itself if you are worried about people stealing your wheels.
This lock doesn’t have the anti-theft warranty that the Kryptonite has but it does still have reinforced steel to reduce the likelihood of cuts and attacks.
This lock comes with 2 sets of keys and is completely waterproof, so the joints and mechanisms don’t rust. Overall for under $30, this lock is really good value and definitely worth runner up on our list.
Pros
- Reinforced steel Umount
- 4ft steel cable
- Flexible
- Comes with 2 sets of keys
Cons
- Steel cable isn’t reinforced
3. Master Lock 8170D U Lock – Best for Classic Cyclists
This classic lock is a straightforward but very effective bike lock that will help to keep your bike secure while you are at work or shopping. While Master Lock has been around for some time, this doesn’t make the Laster Lock 8170D any less secure.
Made from heavy-duty steel with a vinyl coating (making it trickier for cutting), this lock also comes with pry-resistant mechanisms in the U bolts.
The lock itself is 16cm wide by 20cm in length so you can easily fit your classic bike inside and around a lamppost. It also comes with two keys but beware, these keys are high security and cannot be replicated, even if you lose one!
All of this comes in at under $10 which, for a reinforced steel U lock is amazing value.

- Made from heavy-duty steel
- Pry proof joints
- Vinyl powder coating
Cons
- Keys cannot be replaced
- Not suitable for locking in obscure places
4. Via Velo Bike Lock – Best Folding Bicycle Lock
This clever little design is brilliant and gives you a lightweight compact package for your bike lock. The foldable design of the Via Velo Bike Lock has 8 separate plates that are connected together with reinforced bolts to create a space that will fit nicely around your frame and your wheel.
The steel itself is anti-rust and anti-drilling and is covered with a PVC coating so your bike won’t get damaged when using it.
When folded, you can mount your lock onto your bike so you don’t have to carry it and will always have it to hand. This lock comes with 3 keys which is more than the others on our list so far, but just be sure not to lose them!

5. In-Gauge Bike Lock – Best Folding Bicycle Lock
This cable bike lock is made from a flexible cable and a combination lock. The combination lock eliminates the problematic issue of losing your keys and allows you to share the lock with others by giving them the combination code.
The cable itself is 4 feet long and not only works well for bikes but also works well for other products that you might want to keep secured such as toolboxes and gates.
The lock itself is rust-proof, something that isn’t always a given for cheaper bike locks. The in-gauge also comes with a mounting point to attach to your bike so you don’t have to remember your bike lock every trip because it will already be attached to your bike.
This lock comes in at under $10 so is excellent value for money so it’s worth getting a few.
Pros
- Combination lock
- 4 foot of steel cable
- Flexible uses
- Brilliant value for money
Cons

- No pry proof lock system
6. UiiziC Bike Lock – Best for Extra Security
If you are looking for some extra security for your bike, then the UiiziC Bike Lock will help you to fully secure your bicycle. Many people lock their bikes from the frame to a lamppost or a bike park.
But this leaves both of the wheels exposed and at risk of being stolen. So instead, using the UiiziC bike locks around your wheels as well as a lock from your frame will help keep ALL of your bikes safe and not just the frame.
This lock is a combination lock with a tightly wound steel cable that is nearly 6 feet long. This lock can be used for all sorts of security purposes such as locking your laptop bag, stroller, or suitcases up.
While the cable may not look strong, it is made from 1/8 in thick cabling which is covered in plastic so will deter most thieves before they even try to steal anything. A great option as a backup or for extra security.
Pros
- Steel cable
- Combination lock
- Nearly 6 foot long
Cons
- Not suitable for securing your whole bike
- Steel cable is not as strong as others on our list
7. Sportneer Bike Lock – Best for Extra Security
Looking for something that is really heavy duty to secure your heavier-than-average bike? Electric bikes and mopeds are naturally heavier than standard bicycles and as such need a stronger and more heavy-duty lock.
The Sportneer offers just that. This lock has a 5 digit combination lock which gives the thief up to 100,000 possible attempts before they can get in (hopefully they would have gotten bored by then).
Made from 0.27-inch manganese steel that is completely cut-resistant and will ward off any attempts to break into the lock.
The chain itself has an outer covering of nylon fabric so your precious vehicle doesn’t get scratched. Be aware this heavy-duty chain comes with a heavy-duty weight that you will be carrying around on your back or in your bag.

- Heavy duty
- 5 digit combination lock
- 3.2 feet long
- Nylon covered to avert scratches
Cons
- Weighs a lot
- Heavy to carry
8. LiteLok Bike Lock – Best for Big Budgets
Now you might wonder why the Litelok is so expensive and how it can justify the hefty price tag at just over $120, well is because not only does it work as a secure and effective bike lock, but it also doubles up as a belt!
That’s right, you can actually WEAR this bike lock as a belt when you are out and about. Litelok says it is 40% lighter than most other bike locks but at only 1.4lbs, we think it must be more than 40%.
The lock itself is made from a new high-grade material that is as strong as steel but as flexible as plastic which makes it more flexible than the U-shaped locks we have on our list.
The addition to a belt buckle look lock makes it easily interchangeable between a belt and lock. Overall if you have the budget and want a talking point when you get to the office then the LiteLok bike lock is the choice for you.

- Made from high-grade strong material
- Very lightweight
- Interchanges to a belt

The double deadbolt mechanism is pry proof and the disc-style cylinder makes drilling and pulling fruitless. All of this comes complete with 3 keys and makes for a very versatile bike lock.
The best part of this lock is that it is small and easy to carry around. This lock comes with a little bag for keeping it all together in your bag and only measures approx. 5cm x 5 cm.
The Kryptonite range has lots of different locks to choose from and also comes with a handy security rating for each of their locks. You can use their website to look up the different ratings they give each of their bike locks and how they work this rating out.
