Kryptonite New York Fahgettaboudit Chain
Best Overall SecurityPros
- Extremely high security rating
- Durable 14mm hardened chain
- Includes two keys and a bracket
Cons
- Very heavy for daily carry
- Chain can scratch frame paint
The Kryptonite New York Fahgettaboudit Chain is widely regarded as one of the most secure bike locks on the market. It features a 14mm hardened manganese steel chain and a strong disc-style cylinder that resists picking and drilling. Owner reviews consistently praise its ability to deter even the most determined thieves in high-risk urban areas.
The main trade-off is its weight. At over 4.5 kg, it is not a lock you want to carry on a long ride. It is best suited for locking your bike in the same location each day or using a car to transport it. The included bracket helps, but it is still a heavy item.
Hiplok D1000
Best Portable High SecurityPros
- Angle grinder resistant material
- Wearable design for easy carrying
- Lightweight for its security level
Cons
- Shackle size is small
- Higher price point
The Hiplok D1000 uses a unique graphene composite material that is designed to resist attacks from angle grinders. This makes it one of the few locks that can genuinely slow down a thief with power tools. Owner reviews highlight its wearability, as it can be clipped onto a belt or bag, making it much easier to carry than a heavy chain.
The main drawback is the size of the shackle, which can make it difficult to lock your bike to large posts or multiple bikes. It is also one of the more expensive options in this price range. However, for those who need high security on the go, it is a top choice.
ABUS Granit X-Plus 540
Best U-Lock ValuePros
- Excellent build quality from ABUS
- X-Plus cylinder resists picking
- Good balance of weight and security
Cons
- Not as portable as a folding lock
- Shackle can be tight on some racks
The ABUS Granit X-Plus 540 is a classic U-lock that delivers Diamond-level security in a more manageable package than a chain. The 13mm hardened steel shackle and the X-Plus locking cylinder provide excellent resistance to bolt cutters and picking. Owner reviews frequently mention the smooth locking mechanism and the high-quality feel of the lock.
It is lighter than the Kryptonite chain, making it a better option for carrying on your bike frame. The main limitation is the fixed shape of the U-lock, which can be restrictive when locking to awkwardly shaped objects. It is a fantastic all-rounder for city riding.
Kryptonite Evolution Series 4
Best for CommutingPros
- Thick 16mm shackle for a U-lock
- Good value for money
- Includes a flexible cable for wheels
Cons
- Gold rating, not Diamond
- Heavier than some Gold locks
The Kryptonite Evolution Series 4 is a popular choice for daily commuters. It has a very thick 16mm hardened steel shackle, which is actually thicker than the Diamond-rated ABUS Granit. It comes with a flexible cable that allows you to secure your front wheel, adding significant value. Owner reviews praise its reliability and the included mounting bracket.
While it is very strong, its security rating is Gold, not Diamond, meaning it is not recommended for the highest-risk areas overnight. The weight is also a factor, but it is manageable for a daily commute. It is a solid, practical lock that offers excellent protection for the price.
Litelok X1
Best Angle Grinder ResistancePros
- BoeFlex material resists grinders
- Lightweight for Diamond rating
- Good value for the technology
Cons
- Locking mechanism can be stiff
- Not as strong against leverage
The Litelok X1 is a direct competitor to the Hiplok D1000, using a patented BoeFlex composite material that is highly resistant to angle grinders. It achieves a Sold Secure Diamond rating while being lighter than many Gold locks. Owner reviews often note that it feels very modern and provides great peace of mind in high-theft areas.
Some users report that the locking mechanism can be a bit stiff when new, and it may not be as resistant to leverage attacks as a thick steel chain. However, for its weight and the level of grinder resistance it offers, it is a very compelling option for cyclists who want to carry their lock.
What to check before buying a bike lock
Choosing the right lock depends on where you live and how you store your bike. The first thing to check is the security rating. Look for Sold Secure Gold or Diamond ratings. Gold is good for short stops in moderate risk areas, while Diamond is necessary for high-risk urban environments or overnight parking.
Second, consider the weight and portability. A heavy chain is very secure but hard to carry on a ride. U-locks and folding locks offer a better balance. Finally, think about the size and shape of the lock. A small D-lock is secure but may not fit around large posts or bike racks. A longer chain offers more flexibility in where you can lock your bike.
Mistakes to avoid when buying a bike lock
A common mistake is buying a lock that is too small for your needs. Always check the dimensions of the shackle or chain length against the objects you will be locking to. Another mistake is relying on a single cable lock for a valuable bike. Cable locks are easily cut with bolt cutters and should only be used for securing wheels or as a secondary lock.
Many people also ignore the locking method. Always lock your bike frame and at least one wheel to a solid, immovable object. Do not just lock the wheel, as the frame can be easily removed. Finally, do not leave a cheap lock on a high-value bike. Invest in a lock that matches the value of your bike and the theft risk in your area.
FAQs
What is the best bike lock under £150?
The Kryptonite New York Fahgettaboudit Chain is the best overall for maximum security, while the ABUS Granit X-Plus 540 is the best U-lock value.
Is a Sold Secure Diamond lock worth the extra cost?
Yes, if you live in a high-theft area or leave your bike outside overnight. Diamond locks offer the highest resistance to tools like angle grinders.
What is the difference between a U-lock and a chain?
U-locks are generally lighter and more portable, while chains offer more flexibility in locking to different objects. Chains are often heavier but can be more secure.
Can I use a bike lock for an e-bike?
Yes, but e-bikes are heavier and more valuable, so you should use a Diamond-rated lock. A chain lock is often recommended for e-bikes due to its versatility.
How do I carry a heavy chain lock?
Most chain locks come with a mounting bracket for your bike frame. You can also wrap the chain around your seat post or carry it in a backpack.
What is the lightest Diamond-rated bike lock?
The Hiplok D1000 and Litelok X1 are among the lightest Diamond-rated locks, weighing around 1.5 to 1.9 kg due to their composite materials.
How long should a bike lock chain be?
A chain of 90 cm to 120 cm is ideal for most urban locking situations. Longer chains offer more flexibility but are heavier.
Can angle grinders cut through any bike lock?
Most locks can be cut with an angle grinder, but Diamond-rated locks like the Hiplok D1000 and Litelok X1 are designed to resist them for a longer time.
Do I need a separate lock for my wheels?
It is recommended to use a secondary cable or lock for your wheels. Many U-locks come with a cable for this purpose.
What is a Sold Secure rating?
Sold Secure is an independent testing body that rates locks as Bronze, Silver, Gold, or Diamond based on their resistance to various attack methods.
How often should I replace my bike lock?
Replace your lock if the mechanism becomes sticky, the keys are hard to turn, or if it shows signs of physical damage like cuts or cracks.
Can I lock my bike with two locks?
Yes, using two different types of locks (e.g., a U-lock and a chain) can deter thieves as they require different tools to break.
Our verdict
For the best overall security under £150, the Kryptonite New York Fahgettaboudit Chain is unmatched. If you need the best value in a portable U-lock, the ABUS Granit X-Plus 540 is the top choice. For those who prioritize portability and angle grinder resistance, the Hiplok D1000 is a fantastic option.
