How we tested the bike locks

A lot helps a lot! - Tips from Torsten Mendel, security expert at Abus

Bike gone and then what? - Interview with Carolin Mock, insurance specialist at Versicherungskammer Bayern

Bicycle theft is a popular sport, you might think, if you take a look at the statistics: according to police figures, 233,584 bicycles were reported stolen in 2021 - and these are just the official figures. Of course, not every stolen bike is a high-quality mountain bike. According to the statistics, most bikes are stolen in large cities, and these are often station bikes, city bikes or rusty bikes.

However, the number of professional thefts is constantly increasing. The first choice for protecting your bike from thieves is therefore a secure bike lock. Spiral or armoured cable locks usually offer little resistance to thieves and are not an option for high-quality bikes parked in the city. We have therefore focussed on the "heavyweights" in our test: Shackle, folding and chain locks made of hardened steel resist break-in attempts much longer - most hand tools will bite their teeth out on them.

But because even an inattentive moment at the petrol station is enough for your beloved bike to say goodbye from the rear window of a van, you should always have an emergency lock with you on tour. This Practical lightweight locks at least prevent thieves from simply pushing a parked bike away and taking it.

Incidentally, you should not rely on official help if your bike has been stolen. A look at the statistics shows a frightening figure here too: the detection rate for bicycle theft is just 9.8 per cent.

Test bike locks for the city

A bike lock is only as strong as the post you lock it to. We have tested 10 heavy-duty locks that you can use to securely lock your bike at home or in the city.

Abus Granit XPlus 540 SH B

The U-lock from Abus impresses with its top-class workmanship and excellent protection. Only the angle grinder was able to damage the square steel. Handling is just as good, the key slides cleanly and smoothly into the cylinder, the shackle engages smoothly. The tested set includes a somewhat awkward to fit but solid bracket. The connection options are limited due to the design, so lampposts cannot be used as fixing points.

BBB Secure Chain BBL-75

BBB has a good weight-to-length ratio. This provides numerous options for connecting the bike including the rear wheel. The chain lock does not score highly when it comes to transport. Handling with the cylinder rotating when locking is also somewhat awkward. Although the lock fulfils two recognised official test standards, in our practical test the Secure Chain could be cracked using two methods within a very short time. It is therefore only recommended to a limited extent.

BBB Secure Chain BBL-75 | BIKE Verdict²: 33 points - satisfactory

Elops bicycle chain lock 920 L Art 3

The French outdoor giant Decathlon delivers an absolute heavyweight. The length offers many locking options, but transport is only practical in a separate bag. The locking cylinder works a little awkwardly, but this is manageable considering the price. The solid steel chain does not compromise on security. None of the methods used to break it open were effective within the specified time. The bike frame is adequately protected by a continuous textile cover.

Hiplok D1000

It couldn't be more stable. The massive Hiplock D1000 cannot even be cracked with an angle grinder! Accordingly, the lifetime guarantee is absolutely justified. The massive bracket is fully rubberised, providing optimum protection for the frame. The connection options are very limited, with thick frame tubes the lock only reaches around thin posts. When locking, the rubber cover of the cylinder hangs in the way. A bracket is not included in the scope of delivery, which makes transport more difficult.

Kryptonite Evolution 790

There is nothing to criticise about the Kryptonite Evolution 790 folding lock. The solid and easy-to-use bracket can be attached to the frame at many points, and the locking process is permanently smooth. A 360-degree rotating head makes it easier to bring the lock together. Six extensively rubberised links allow flexible connection options and prevent scratches on the frame. The lock could not be picked with any of the standard methods in the time available. Only the angle grinder got through.

Litelok One Wearable

The flexible Litelock One wearable is available in three lengths and can be worn practically as a belt. The lock can also be attached to the frame using a bracket. In relation to its weight, the Litelock offers many connection options. However, if the connection points are further away, the stubborn strap can only be inserted into the lock with force. In the picking test, the lock could be picked within the time limit using one method, while another method only required slightly more time.

Manufacturer information:

• Price: 149,95 Euro
• Weight¹ / length: 1330 g / 100 cm
• Accessories: 2 keys; 2 fastening straps; can be worn as a waist belt

• Equipment (10 %): 8 out of 10 points

Litelok One Wearable | BIKE judgement²: 45 points - good

Masterlock U-lock 8279

The Masterlock comes with a somewhat awkward mounting bracket that only fits tubes up to 35 millimetres in diameter. The lock wobbles noticeably while riding. The feel of the 8279 U-lock is also not a highlight - the plastic coating looks cheap. On the other hand, it is well equipped: four keys, light, protective cap for the lock cylinder. The Masterlock also performed well in the break-open test: no standard tool was able to damage the lock.

Manufacturer information:

• Price: 71,95 Euro >> available here
• Weight¹ / hanger dimensions (inside): 1155 g / 21.5 x 10.6 cm

Trelock FS 580 Toro X-Press

The Trelock folding lock is identical in construction to the model Kryptonite Evolution 790. The bracket is also identical, easy to mount on the bottle cage or frame and convenient to use. The locking process of the high-quality lock runs absolutely smoothly, and the 360-degree rotating head makes it easier to bring the links together. The length and weight make it easy to transport and connect. Like the Kryptonite, the Trelock FS 580 Toro only gave way in the test when attacked with an angle grinder.

Manufacturer information:

Seatylock Foldylock 90

With the Foldylock 90, Seatylock also supplies a high-quality folding lock with sufficient length and good locking options. The flexible lock can also be easily folded in angled positions. The lock sits wobble-free in the practical holder and the locking process is very smooth. To prevent scratches on the frame, the Foldylock is completely plastic-coated. In the test, the lock could be opened within the time limit using one of the available methods.

Manufacturer information:

• Price: 109,95 Euro >> available here
• Weight¹ / length: 1625 g / 90 cm
• Accessories: 3 keys; frame holder; key service

Contec Powerlok

At first glance, the very affordable Contec with its thin bar doesn't inspire much confidence. In the test, however, it easily withstood all attempts to prise it open and is therefore an absolute winner. Price-performance tip. The equipment is lavish: four keys, light, frame holder. However, the latter does not seem very stable, is somewhat awkward to mount and quite fiddly to operate. The plastic coating is also not particularly durable and tears easily. Very good: The wide bracket reaches around even thicker posts.

Manufacturer information:

• Price: 39,95 Euro >> available here
• Weight¹ / hanger dimensions (inside): 1310 g / 23 x 11.5 cm
• Accessories: 4 keys; 1 key with light; key card; frame holder

Test bike locks for travelling

Also put to the test: 6 lightweight alternatives for travelling on tour. Not all of them put up enough resistance to our attempts to set off.

Abus Sportflex 2504

Even if it may not look like everyone's cup of tea: the lightweight Abus is practically mounted on the bottle cage and is therefore always on board. Don't forget to enclose the frame, otherwise the lock can simply be unscrewed! The length is easily long enough to lock two bikes or to attach it to a post, the numbers on the lock are easy to read and the four dials are neatly rasterised. The Sportflex is a good option if the bike is parked within sight during a break.

Manufacturer information:

• Price: 39,95 Euro >> available here
• Weight¹ / length: 98 g / 95 cm
• Special features: 4-digit numerical code; integrated holder
• Certification: not certified

BIKE rating:

• Handling (20 %): 10 out of 10 points
• Weight (10 %): 10 out of 10 points
• Equipment (10 %): 8 out of 10 points

Abus Sportflex | BIKE judgement²: 42 points - good

BBB MiniCase BBL-53

The BBB MiniCase is the absolute minimum solution for a quick stop at the petrol station or a break at the hut. It fits in any jersey or trouser pocket. The dials on the fastener have a good grid and the numbers are easy to read. However, the fastener and cable are quite snaggy, which makes handling difficult. The biggest drawback is the length of the cable: This barely reaches around thicker posts. The mini lock can only resist the simplest of tools for a very short time.

Manufacturer information:

• Price: 17,95 Euro >> available here
• Weight¹ / length: 45 g / 58 cm
• Special features: 3-digit numerical code
• Certification: not certified

• Handling (20 %): 8 out of 10 points
• Weight (10 %): 10 out of 10 points
• Equipment (10 %): 4 out of 10 points

BBB MiniCase BBL-53 | BIKE Verdict²: 35 points - satisfactory

Hiplok Z-Lok

The Hiplok Z-Lok works like an oversized cable tie with a steel core. Thanks to the three-digit numerical code, it can be used again and again. Alternatively, the practical and lightweight locks are also available with a special key. However, it is not just the handling that is criticised: the numbers are barely legible and there is no grid. The length is also just long enough to attach the bike to a thin post. As with the BBB even the simplest tools are enough to pick the lock.

Manufacturer information:

• Price: 19,99 Euro >> available here
• Weight¹ / length: 69 g / 50 cm
• Special features: 3-digit numerical code
• Certification: not certified

BIKE rating:

• Break-in security (60 %): 2 out of 10 points
• Handling (20 %): 7 out of 10 points
• Weight (10 %): 9 out of 10 points 10 out of 10 points
• Equipment (10 %): 6 out of 10 points

Hiplock Z-Lok | BIKE judgement²: 34 points - satisfactory

Ottolock Cinch Lock

The Ottolock Cinch Lock is also similar to a cable tie in the way it works. However, it is somewhat more stable than the Hiplok Z-Lok and can withstand attacks for longer. It can be rolled up small for transport and fits into a jersey or rucksack pocket. The medium length is easily sufficient to attach the bike to thicker objects. Although the combination lock has a noticeable notch, the discs keep twisting by themselves, especially when you're wearing gloves.

Manufacturer information:

• Price: 84,95 Euro >> available here
• Weight¹ / length: 178 g / 76 cm
• Special features: 3-digit numerical code; rubber sleeve for transport; 3 lengths
• Certification: not certified

• Break-in security (60 %): 5 out of 10 points
• Handling (20 %): 8 out of 10 points
• Weight (10 %): 9 out of 10 points
• Equipment (10 %): 6 out of 10 points

Ottolock Cinch Lock | BIKE judgement²: 41 points - good

Trelock FS 280 Two.Go

If you want to be on the safe side when travelling, you should take a closer look at the compact folding lock from Trelock. Eight robust bars ensure good flexibility and sufficient locking length. The practical bracket makes it easy to attach to the frame, but also light enough to carry in your rucksack. Handling and workmanship are of a very high standard. The Trelock FS 280 Two.Go cannot be cracked with simple tools that are available when travelling. However, the lock is not a safe choice for longer parking periods in the city.

Manufacturer information:

• Price: 64,99 Euro >> available here
• Weight¹ / length: 532 g / 80 cm

Trelock FS 280 Two.Go | BIKE judgement²: 49 points - good

Voxom SCH1

The Voxom is hard to beat in terms of weight to connection length ratio. You can easily connect several bikes together or attach them to one object. The SCH1 fits into even the smallest bag. However, you shouldn't expect too much in terms of handling and security: the combination lock is quite stiff and the numbers are not easy to read. The cable wears out after prolonged use. Even simple tools can be used to crack it, so it is only recommended for bikes parked for short periods and within sight.

Manufacturer information:

• Price: 9,95 Euro
• Weight¹ / length: 55 g / approx. 110 cm
• Special features: 3-digit numerical code
• Certification: not certified

BIKE rating:

• Break-in security (60 %): 3 out of 10 points

How BIKE tested the bike locks

The bike locks in the lab test

For the break-in attempts, we used the most common tools according to the police: A sledgehammer, hacksaw and bolt cutters can easily be carried by thieves under a jacket. We had a maximum of three minutes per attempt. The "intelligent" opening of bike locks using tools hardly plays a role in practice. That is why we did not use it in the test.

The weight of the locks was assessed in relation to the internal dimensions of the lock - a longer lock also offers more flexibility when fastening. Due to the low protection level, the lightweight locks could only be worked on with side cutters, a hacksaw or by hand.

Practical test of bike locks

In terms of handling, we tested the ease of movement of the locking mechanism in numerous locking processes. We also tested the various locking options and assessed the installation of the frame brackets and the clean fit of the locks. When evaluating the features, we took into account the number of keys supplied, the lock holder and the operating instructions. Manufacturers were able to collect bonus points if they offered additional keys or other features such as key lighting.

A lot helps a lot! - 6 tips on bike locks from the security experts at Abus

Thin cable locks can be easily picked even with a side cutter. What makes a good lock and what else should you look out for when buying one? We asked Torsten Mendel, security expert at Abus.

1. buy a high-quality lock

The quality of the bicycle lock should always be selected depending on the value of the bicycle (guide value: lock price corresponds to 10% of the bicycle purchase price) and the storage location. Leasing bike providers or insurance companies often require locks of a certain price or protection class. If you have locked your bike with a cheap lock and it is stolen, the insurance company may refuse to pay compensation. The best way to find out which requirements a lock must fulfil is to ask your insurance company.

2. the security levels

Although all manufacturers categorise their locks into different protection classes - the higher the value, the more secure the lock - there is no uniform standard for bicycle locks in this country. What is security level 5 for one manufacturer may be protection class 15 for another. Independent test seals, such as those issued by the ADFC, provide an indication of quality. Bicycle owners with
bicycle owners with theft insurance are also often recommended the VdS seal (trust through security). In the case of high-quality bicycles, some insurance companies even require this seal of approval in order to be able to make any claims at all.

3. hands off it

Thin spiral cable locks are usually particularly easy to pick. Armoured cable locks also often offer little protection against bolt cutters etc. These locks should therefore only be used for short periods of time. The most secure models in the test are U-locks, folding locks and chain locks - but here too, the quality of the material is very important. Secure locks are often also very heavy. A good U-lock can weigh as much as two kilos. The width of the shackle is a limiting factor when locking. Although chain locks offer many options for locking the bike, they are cumbersome to transport. Flexible folding locks are a good combination - small pack size and good attachment options.

4. two are better than one

Two locks are better than one. For example, attachments such as wheels or the saddle can be additionally protected with a longer cable lock. Also look out for different designs - U-lock and cable lock, for example - or models from different manufacturers. This increases the likelihood that a thief will not have the right tool with them. There are also thieves who specialise in locks from certain brands and are deterred by "other brands".

5. secure correctly

Locking instead of just locking is the magic word here. The object to which the bike is locked should be at least as strong as the lock used. Thieves always start at the weakest link in the chain. Wire mesh can be easily cut with a side cutter, a thin wooden trunk can easily be sawn through. Sturdy iron bicycle stands or a lamp post are best suited. The lock should be mounted as high as possible to provide less cover for the perpetrator. This also means that a bolt cutter cannot be propped up against the ground. Public places are better than dark corners. Highly frequented places are more likely to deter thieves. In your own home, the bike can be secured to wall or floor anchors. In the bicycle cellar of an apartment block, you should always lock several items together. This makes it harder to carry them away.

6. good to know

In order to be able to make a claim or file a police report in the event of theft, you should always keep the invoice for your bike and make a note of the frame number. Also make a note of any conspicuous features such as brand, colour and accessories. You can also obtain a bike passport or the police bike passport app. A photo of the bike can also help with regulation.

Bike gone and then what? - Interview with Carolin Mock, insurance specialist at Versicherungskammer Bayern

Even the best lock does not offer 100% protection against theft. If your bike is stolen despite being in "safekeeping", household contents insurance or special bicycle insurance can help. We clarify the most important questions on the subject.

Read the terms and conditions of your insurance policy carefully. In the event of theft, the new value of the bike should be reimbursed. The cover should be valid worldwide and 24 hours a day. Time clauses and being tied to certain types of locks are now outdated requirements. The police must be informed in the event of a break-in. Only then will the insurance company reimburse the costs.

Household contents insurance

"If the bike is stolen from your home or a locked cellar compartment, this is considered burglary. In this case, your bikes are usually covered by your household contents insurance," explains Carolin Mock from Versicherungskammer Bayern. However, bike owners should pay close attention to the details: For example, the amount of compensation is often only one per cent of the total sum insured. With a sum insured of 50,000 euros, the insurance will therefore only reimburse 500 euros in the event of theft.

Not every insurance policy covers shared cellar compartments either, because several people have access to the premises and there are usually no signs of burglary. The time clause that used to be common, according to which bicycles were only insured between 6 a.m. and 10 p.m., is rarely used today.

With providers such as Versicherungskammer Bayern, bicycles can be insured via a extended household contents insurance additional protection. For a small surcharge on the premium, the bikes are then insured at replacement value, regardless of the purchase price. "The cover applies around the clock, worldwide. However, the prerequisite for this is that the bike has been secured with a lock," explains Mock. In some cases, a certain price range is also specified for the lock. Loose items, such as a speedometer or luggage, are not covered by the insurance. This is a case of simple theft. You should therefore always remove any parts that are not permanently attached as soon as you park your bike.

Special bicycle insurance

One Bicycle insurance is particularly worthwhile for expensive bikes that are sometimes left outside at night and are not covered by household contents insurance. The market for specialists has grown considerably in the meantime. In addition to the pure Theft protection some providers also offer a so-called Fully comprehensive bicycle insurancewhich, in addition to covering repair and wear and tear costs, can also include a cover letter for breakdown and accident assistance.

The theft of permanently connected Sharing or travelling luggage is usually covered up to a certain amount. Caution: some providers exclude the Participation in races or do not insure Carbon frame. Also check whether the insurer has a Lock of a certain price or protection class and how to secure the bike. Top: Even Used bicycles can be insured today, and the cover is often valid worldwide - particularly practical if you travel a lot.
