The Abus Bordo Granit X Plus 6500 is one of only two high security, folding bike locks currently available (the other being the Trelock FS 500). And it’s a great choice if you don't want to carry a bulky u-lock around.

However, the Bordo 6500 comes with a couple of surprises. So before you decide this is the best lock for you, read my full hands on review.

I’ll talk about how secure it is, how easy it is to carry around and use. And if it’s not quite right for you, I’ll suggest some alternatives.

The lock, case and two keys

How secure is the Abus Bordo 6500?

This is the first surprise. Abus themselves give it a 15/15, maximum security rating. And Sold Secure have tested it and awarded it a Gold rating. This makes it a high security bike lock for high risk situations.

However, ART have also tested it and only gave it 2/5 stars. Now, 2/5 stars from ART isn’t bad. But it’s a score that used to be equivalent to a Silver rating from Sold Secure.

Now times have changed, and there are quite a few Gold rated locks that also have 2/5 stars from ART. But most Gold rated locks have 3/5 stars if they're rated by ART.

So what do we deduce from this? Well, the Bordo 6500 is still a high security lock. But it’s at the bottom end of the Gold rating; other Gold rated u-locks will be more secure than the Bordo.

This is because folding locks are inherently less secure than equivalent u-locks. The bars are thinner than u-lock shackles. And the nuts that hold the bars together are also susceptible to attack...

In the video above, the LockPickingLawyer manages to shear one of the nuts holding the bars together with his "nut splitter". We should note that this isn't a commonly used tool and the lock was held in a vice at the time. So not typical street theft conditions!

But it does show that folding locks have this inherent security weakness around those nuts!

Also, the bars of the Bordo 6500 are just 5.5 mm thick. And this is significantly thinner than the shackles of Gold rated u-locks, most of which are at least 13 mm.

Having said that, when it comes to resisting bolt cutters, the width of the bars is important too. And the bars of the Bordo 6500 are significantly wider than any other folding lock (or indeed u-lock).

For instance, while the 5.5 mm bars of the 6500 are only 0.5 mm thicker than the bars of it’s little brother, the Bordo 6000, they are also 7 mm wider.

So while there’s plenty of videos of 30″ bolt croppers defeating the Bordo 6000, we’re unlikely to see any such videos of the Bordo 6500. It’s much tougher than that.

Bordo 6500 vs 6000

The Bordo 6500 is thicker, and wider and has bigger rivets than the 6000

So, for sure the Bordo 6500 is much more secure than the 6000. In fact it’s far more secure than pretty much any other folding lock.

It’s an acceptable lock for high risk situations. It’s just not as secure as some of the other Gold rated u-locks.

Is the Abus Bordo 6500 easy to carry?

This is where folding locks really shine!

The problem with u-locks is that when you attach them to your bike, their center of gravity is away from the frame. And the frame mounts struggle to hold u-locks firmly in place when their weight is distributed in this way. This means they can work loose, rattle and even fall off.

Generally, the more secure a u-lock is, the heavier it is. And the heavier it is, the more weight is distributed away from the frame, and the more the frame mount struggles to hold the lock in place.

Some of the heaviest, high security u-locks don’t even come with frame mounts for this very reason.

Since folding locks collapse down into a neat, compact package, we shouldn’t have this problem, even with a relatively heavy, high security lock like the Bordo 6500.

When they’re in the case, their center of gravity is very close to the frame. And this means the frame mount has much less trouble holding them in place. There shouldn't be any movement, rattling or falling off!

The Bordo 6500 comes with a sturdy rubber frame mount

The Bordo 6500 comes with a very sturdy plastic and rubber frame mount which can be attached to your bike in two ways…

If your bike has holes for attaching a water bottle mount, you can screw the frame mount into these. If not, the case comes with two thick Velcro straps that will fasten it anywhere on your frame.

You can screw it into the water bottle holes or attach it with velcro

There is a supper thick rubber strap that folds over the top of the lock once it’s in the case. And this keeps the lock firmly in place while you’re riding.

I tested the frame mount on two different bikes. One has the holes for a water bottle mount, so I was able to screw the case directly into the frame. While the other doesn’t, so I had to use the Velcro straps to attach the case to the frame.

Using water bottle mount screws

Both methods worked well. The frame mount fixed tightly against the frame and while there was some give owing to the rubber construction, there was no unwanted movement, no rattling and I felt secure it wouldn’t work loose over time.

However, while both worked well, I much preferred using the screwed mount. For starters, it felt slightly more secure and looked neater. But more significantly, with the Velcro method, you end up with excess lengths of strapping flapping about on one side of the mount.

Using the Velcro straps

Of course you could trim them down. But then you might run into trouble, if you move the lock to a bike with a fatter frame. It would be nice if there was a space that you could tuck the ends into. But at the moment there isn’t.

The compact folded form of the Bordo 6500 is also great if you need to transport it by some other method, such as a backpack. Folded down the Bordo 6500 measures just  7.75″ x 3″ x 2″ (19.5 x 7.5 x 4.5 cm). This is far smaller than any u-lock and makes it easy to slip into a bag.

The Bordo 6500 folded up

The Bordo 6500 folds down to a very small, compact package!

Weight wise, the Bordo 6500 also performs pretty well for a high security bike lock. At 3.48 lb (1.58 kg), it’s lighter than most other Sold Secure Gold bike locks.

However apart from a couple of mini u-locks (which you’d expect to be lighter) there are other standard sized, Gold rated u-locks that are lighter than the Bordo.

Both the Abus Granit X Plus 540 and the MasterLock 8195D are lighter while actually offering more internal locking space!

So yes, it’s pretty light. But the real advantage of the Bordo 6500 is the way it folds down into a compact package.

And whether in the frame mount or in a separate bag, this makes it much easier to carry than a standard sized, high security u-lock. For more on carrying options, check out my where to put a bike lock when riding page.

Is the Abus Bordo 6500 easy to use?

Like all folding locks, the Bordo 6500 is pretty simple to use. It slips out of the frame mount very easily (which contrasts favourably with some U-lock mounts which are much harder to operate!).

Then you just fold out the middle bars (to make it easier to release the locked bar), unlock the mechanism and pull the bar closest to the key to unfasten it.

Actually getting it around your bike and an immovable object will be easy or hard, depending on your immediate circumstances.

Abus Bordo Granit X Plus 6500 on bike

The Bordo 6500 in the street

In a quiet or empty bike rack, I find a standard sized u-lock easier to use than a folding lock. You just need to line everything up and push the shackle through.

With a folding lock you have to thread one end through the wheel, around the frame and then around the immovable object. It’s more fiddly, you need two hands, and it usually takes more time.

However, in a busy bike rack where it’s harder, (if not impossible) to line everything up, a folding lock is more useful.

In these circumstances, owing to it’s flexibility, it’s much easier to get a folding lock around your bike and secure it correctly. With a u-lock it may not be possible so you either lock your bike in a less secure manner or you find somewhere else.

So the flexible shape certainly gives you more options when you’re trying to lock your bike. But don’t make the mistake of thinking that the extra length of the Bordo 6500 will also make things easier.

Why? Because there is no extra length! And this is the second surprise...

Abus Bordo 6500 vs Kryptonite Kryptolok

The Bordo 6500 has less internal locking space than a standard sized U-lock

I think, many people presume that folding locks are really long. But in fact the Bordo is just 2.75′ (85 cm). And this actually gives you slightly less internal locking space than a standard sized u-lock.

So the Bordo 6500’s advantage over a standard sized u-lock is it’s flexibility rather than it’s length.

Like all Abus locks, the Bordo 6500 comes with two keys. And if you already have other Abus locks that have the same cylinder, you can get this one keyed alike so that all your locks can be opened with the same set of keys.

You get 2 keys with the Bordo 6500

It’s also worth mentioning that the lock is covered with a hardy plastic coating that should resist the weather well and has softer rubber edges that will protect your paintwork.

Conclusion

I’ve used the Abus Bordo 6500 for a couple of weeks and I think it’s a great lock. However, it won’t be for everyone. To help you decide, here’s the things I liked about this bike lock and the things I didn’t…

+ Highly portable

It’s pretty light for a high security bike lock. But more significantly, it folds down into a very compact package that’s really easy to carry around. Whether it’s tucked tightly away in the frame mount or slipped into a bag it’s extremely inconspicuous.

+ Lot’s of locking options

While the Bordo actually has slightly less internal locking space than a standard sized u-lock, the flexible shape means you’ll be able to lock your bike to things (and in ways) that would be denied to you with a u-lock. Lampposts for example!

– Can be fiddly to use

Despite the additional locking opportunities the Bordo gives you, I still think a standard sized u-lock is generally easier to use. I tend to lock my bike faster with a u-lock than any folding lock.

– Expensive

Abus locks can be expensive. Folding locks also tend to be expensive. So a folding Abus lock will always be expensive! You know you’re going to get the best quality with Abus. But there are cheaper Abus locks that offer better protection if that’s your priority.

Wrapping up

Yes, there are more secure locks than the Bordo 6500. Some of them offer more more internal locking space. And many of them will be cheaper as well.

But the Bordo 6500 is one of the only high security, folding bike locks currently available. And folding locks have two big advantages over other types of lock…

Firstly, they fold down into a really compact shape that’s super easy to carry around. Secondly, the flexible shape gives you more locking options (even with a short lock like the Bordo 6500), so that places and things that are out of bounds with a u-lock, become feasible.

If these two advantages are important to you and you need a high security lock for high risk situations, then the Abus Bordo 6500 [Amazon] really is the best choice for you.

The Abus Bordo Granit X Plus 6500 is one of only two high security, folding bike locks currently available (the other being the Trelock FS 500). And it’s a great choice if you don't want to carry a bulky u-lock around.

Alternatives to the Abus Bordo Granit X Plus 6500

Of course, if the Bordo 6500 isn’t the best lock for you then there’s always loads of alternatives…

Looking for something more secure?

Abus Granit X Plus 540

The Bordo 6500 is a high security, Sold Secure Gold rated lock. But since it only has 2/5 stars from ART, it’s probably at the lower end of that rating.

If you need something more secure, then you’ll have to go with a u-lock. How about the Abus Granit X Plus 540 which is also Sold Secure Gold but has 3/5 stars from ART?

Not only is it more secure than the Bordo. It’s also lighter and offers more internal locking space. All for around the same price!

True, you won’t be able to fold it down into a nice compact package like the the Bordo. It wont be as easy to carry.

But the frame mount is one of the best around, so you shouldn’t have the transport problems you get with other u-locks.

In fact, for me, the X Plus 540 is the best high security bike lock currently available. Check out my full review here.

Looking for something cheaper?

OnGuard Pitbull STD

The Bordo 6500 is probably one of the most expensive portable bike locks you can buy! Personally, I think that if it meets your needs then it’s worth it.

But if you can’t stretch that far, then there’s plenty of other locks that will protect your bike just as well, for a fraction of the price.

The OnGuard Pitbull STD [Amazon] is also rated Sold Secure Gold. And with a 14 mm shackle is almost certainly more secure and only slightly heavier than the Bordo.

Obviously, like all u-locks, you can’t fold it up! 

But the frame mount the comes with the Pitbull isn’t a bad one. And it’s usually less than a third of the price of the Bordo! Bargain!

Looking for something longer?

Abus Granit CityChain X-Plus 1060

At 2.7′ (85 cm), the Bordo 6500 isn’t very long. If you need more length, but want to retain the same level of security, then you’ll need to go with a chain lock.

With 10 mm links, the Abus Granit CityChain X-Plus 1060 [Amazon] is also rated Sold Secure Gold and Abus themselves also give it a maximum 15/15 security rating.

What’s more, ART tested it too and awarded it 3/5 stars, so it’s actually more secure than the Bordo!

It’s available in four lengths: 2.8′, 3.6′, 4.6′ and 5.6′ (85, 110, 140, 170 cm). The problem is that chain locks are always more heavy. For example at 5.84 lb (2.65 kg) the 3.6′ chain is 68% heavier than the Bordo!

If you wanted something lighter, the 9 mm Abus CityChain 1010 [Amazon] is also Sold Secure Gold, although Abus only rate it as 12/15. It’s available at the same lengths as the X Plus 1060. But the 3.6′ version is only 50% heavier than the Bordo at 5.29 lb (2.4 kg).

Yep, chain locks are always much, much heavier than other bike locks. But if you need that extra length with out sacrificing security, they’re the only way to go!

  • Hello ,

    Awesome job with these reviews dude you have been really really helpfull, so I have a question about the “Folding Lock BORDO Black Edition GRANIT X Plus™ 6510”. Is the same as the regular 6500 that you reviewed just with all black colour? or it offers s0mething more that I am not aware off?

    Thanks a lot you are the best!!

    • Hi Paris,

      No, as far as I’m aware it’s the 6510 is the same as the 6500. It’s just black rather than grey and comes with some fancy packaging. It was released to celebrate 10 years of the Bordo range. But in terms or construction and protection it won’t provide anything that the 6500 doesn’t provide!

      I hope that helps.

  • Had the Granite X lock for 3 years (and never had any problems even when parking my bike in sketchy places of San Francisco for several hours during the night) but last Sunday my bike was stolen on a busy street during daytime while I was gone for 45 minutes getting lunch.

    Unfortunately the lock is gone with the bike, so I don’t know how the lock was defeated. https://thesweethome.com/reviews/best-bike-lock/ claims that the pins that connect the individual links are unhardened and that drilling them out is very quick.

    Just based on the comfort level this was the best (secure?) lock I ever had as it was really easy to transport and as it was more flexible than a ulock. Not getting another one though – I’ll be using a Fahgettaboudit for my new bike.

    • Ahh that’s unlucky. But yes, folding locks will always be less secure than the best U-locks. Remember, even though the 6500 is Sold Secure Gold (and is the only folding lock that has a Gold rating), it only has 2/5 stars from ART. That’s the same as the Kryptonite Kryptolok which I would definitely not recommend for high risk situations.

      You’ll definitely be much safer with the Fahgettaboudit!

  • Hi

    Just wonder if I would be able to lock two bikes like you did with Bordo 6000? I know its shorter 5cm but does it make such big differences to do that? thanks.

    • Hi Peter,

      Yes I think it’s possible. When I’ve got a spare moment I’ll give it a go and post a photo.

      However, I think it will be a tight squeeze, even in the most favorable position. So I can imagine there’ll be loads of situations where you won’t be able to as well!

      Thanks
      Carl

  • I’ve had trouble with the lock cylinder becoming difficult to turn after a couple of years of use in all kinds of weather.

    Fortunately it’s surprisingly easy to disassemble the lock cylinder, allowing it to be thoroughly cleaned. All it takes is the key and a standard philips screwdriver. As you get closer and closer to the heart of the mechanism, the parts get smaller and smaller. Good eyes and a steady hand is a must. Wiped the internals down and gave them a small squirt of lock oil. Happy to say that my lock now feels as smooth as new.

    Make sure not to mess up the order or orientation of the tiny discs within, or they will no longer match your key. I kept them threaded onto the key while working.

    It’s only possible to disassemble it when already unlocked. The security is not compromised by the ease of maintenance.

  • I’m using the 6500 as a secondary lock with a u lock, so have had no issues also have a Pewag 1/2 12mm square chain galvanized wi
    Th cover and viro lock for home sold through western rigging. Weighs in at 12 lbs for 4 feet have brought it along in the pannier but little heavy to quickly lock up for a fast stop.

  • I had an Abus Bordo Centium which was great to use. I carried it in my saddlebag. Went over a bump and the thing bounced into the street and can no longer open using either key that came with it. I don’t have a good place to strap it to the frame of my bike. Am debating buying another or moving on.

  • Hello Carl,

    I bought this bike
    https://www.totemusa.com/product-page/cs-260-commuter-series-foldable-electric-bicycle
    which has a rather high frame (11 cm in height) because it contains the battery inside.
    I would like to buy a Gold Sold Secure lock but I haven’t decided yet which one. In a previous post I told you I was thinking about the Kryptolok New-U ATB because of its width (12.7 cm) and height (23 cm), however by trying an old U lock with similar width, I think that a folding lock would be more practical for this bike. I am however concerned about the length of the Abus Bordo 6500 85 cm. I think that, as you show in the photo, it will give the same height as a U-lock. I saw that there is also a 110 cm version of Bordo 6500 but which is quite heavy (2.2 Kg). Do you have any other suggestions?

    Many thanks for your help!
    Lampros

    • Hi Lampros,

      Unfortunately if you need that extra length then the locks are going to get heavy.

      However there is the Litelok.

      The large version will give 103 cm of locking circumference. And it only weighs 1.46 kg.

      Plus you can also wear it around your waist so it’s really easy to carry!

      I hope that helps!

      Carl

      • Thank you Carl for the suggestion.
        I saw however several videos of Litelok being destroyed quite easily in a matter of seconds…
        I will think about it thoroughly though..

        Thanks!
        Lampros

        • OK no worries Lampros!

          Just to provide some defense of Litelok though…

          The only significant video of the Litelok being destroyed is the one by the LockPickingLawyer.

          The other videos (that I’m aware of) are either an angle grinder attack (all locks can be defeated by angle grinders) or a strange twisting attack (that I wasn’t able to reproduce and I’ve never heard of anyone else reproducing).

          Now for sure: that the (Gold rated) Litelok can be defeated with a hand tool is not good at all.

          But although all bike thieves carry cable cutters (or bolt cutters than can cut cheap cables), that type of cable cutter is not a commonly used tool by thieves.

          Unfortunately the LockPickingLawyer also defeats the Abus Bordo 6500 with a hand tool (nut splitter). Which is again disappointing for a Gold rated lock. Although again, it’s not a commonly used tool.

          The problem is that both the Litelok and the Bordo 6500 are trying to give us more convenience. And to do that they inevitably sacrifice some security.

          Since your lock is an expensive ($600+) bike, then you may want to put up with some inconvenience and get a thick u-lock or chain!

          • Thank you Carl.
            You are right, I think I will buy a chain lock, like the Abus Citychain 1010/85.

            Thank you again,
            Lampros

  • Personally, I think it’s extremely foolish to put all faith into a single lock, no matter how well rated it is. Follow the lead of those in Amsterdam who use a minimum of two different types of locks, and locking methods. One to lock a wheel, the other to secure the frame to something. With twice the hassle, thieves will likely move on.

  • Good reviews overall. I have an Abus Bordo 6100 combination folding lock. It’s a step down from the 6500 and it’s rated as medium security but I really like the convenience of a combination lock. I live in a low-crime area and garage my bike at night, so it’s good while I’m in the store or gym, although I would gladly pay $200 for a combination version of the 6500 if Abus offered it.

    I might quibble with your conclusion that a folding lock has less internal locking space than a U-lock. Because a folding lock’s arms shift positions, you can change its length to more effectively reach around/through different kinds of objects. Can’t do that with a U-lock. You literally have a lot more flexibility with a folding lock so it is similar to a chain in that regard.

    • Hi Marty,

      Thanks for your comment!

      I agree that it’s a shame Abus don’t offer a combination version of the 6500. Maybe it’s because combination locks are generally less secure? I’m not sure.

      I also agree that folding locks give you loads more locking options than u-lock, due to their flexibility.

      There’s definitely less space inside the 6500 than standard size u-lock (like the Kryptolok) though. I know because measured it!

      There’s not a huge amount of difference, it’s true. But I mention it because I think a lot of people expect folding locks to provide a bigger locking circumference and they don’t

      Cheers!

  • These reviews are extremely helpful! I’m looking at the Abus Granite X Plus 540 U-lock but don’t know if I’ll be able to mount it to my bike very easily (I already have a water bottle mounted on the frame). I had high hopes for the Bordo 6500, but it doesn’t seem secure enough. I’m curious why the Abus alarm locks aren’t rated higher for security, given that they’d almost certainly scare off a bike thief right away (the Folding Lock BORDO™ Alarm 6000A is only a Sold Secure Bronze, and the U-Lock 440 Alarm is a Silver). Am I overestimating the deterrent power of an alarm? Seems like the best advice is to use 2 different kinds of locks that would require different tools to defeat them.

    • Hi Marisa,

      When they’re determining the security level of lock, they can’t really take into account of the alarm as it’s effect is beyond the control of the lock: some thieves will run away, some will ignore it.

      But it’s true: all the alarmed locks always seem to be medium security. I wonder if an alarm system would make already heavy “high security” locks prohibitively heavy?

      The Bordo 6500 might be secure enough for you, depending on your circumstances.

      But one of the best things about a folding lock is the way the frame mount can fit in your water bottle holder, and yours is already full!

      You should be able to find somewhere on your frame to put the X Plus 540 though, the frame mount is very versatile.

      Cheers

      Carl

      • Thanks for your speedy reply! Follow-up question: If I wanted to combine 2 locks to try to dissuade an opportunistic thief, what 2 locks might make the best team? My head is swimming with all the possibilities, and I’m also trying to find a way to avoid adding tons of weight to my new lightweight bike. 🙂 Assuming I’m able to attach the X Plus 540 to my bike somewhere, or maybe the 6500 instead, I wonder if there’s another lock I might combine with one of those to add a level of security. I just don’t know what makes sense, and maybe I’m being paranoid!

          • Sorry—I tried replying earlier but it didn’t go through. Anyway, I’m higher risk while riding around the city; we’ve had lots of bikes stolen around here. FYI, I did go ahead and buy the X Plus 540 U-lock, so I’ve been using that successfully. Just wondering what the best companion lock might be for it.

          • Hi Marisa,

            Well, the X Plus 540 is a great lock. You could use something as un-secure as a cable. Or as secure as a smaller u-lock.

            It depends how much your wheels and seat are worth and how they’re currently attached.

            I like Hexlox for securing wheels and seats as they’re pretty secure, don’t weigh anything and don´t need to be locked up every time you secure your bike.

            I hope that helps!
