Abus Bordo 6500A SmartX lock review: A lock without a key

While working on our list of the best bike locks one of the things we identified was how much people appreciate folding locks. Bike shops tend to sell them a lot because they are convenient to use, and you get an easy-to-mount lock that’s got more adaptability than a U-lock. The problem is they aren’t always the most secure option.

The Abus Bordo series of locks bucks the trend by offering a Sold Secure Gold folding lock. Among the options for the Abus Bordo line of locks, the 6500 is the most secure but there are a few variations. The standard key lock is the most common available but there’s also an alarm version with keys and the Abus Bordo 6500 SmartX at the top of the lineup.

The SmartX is expensive and cutting edge, but does it work? After spending time testing to see what it was like to use, we are ready to share. If you’ve had your eye on the ultimate folding smart lock, keep reading to see our thoughts on using it. Security means weight but a folding lock makes it easier to carry.

(Image credit: Josh Ross) Design and aesthetics I’ll say it a few times in this review but the Abus Bordo 6500 locks are essentially the same. That makes for nine variants spread between three model names with the differences being a combination of extra features and length. If you’d rather stick to a key lock, that’s an option in either 85 or 110 cm, you can add an alarm to the key lock version, or there’s the most feature-rich version which we are looking at specifically.

The SmartX variation means there is no keyhole and instead it operates with a battery and Bluetooth. Like the KA version, the SmartX does include an alarm. It’s not the main draw on this version but if it gets hit hard enough it will sound for five seconds before resetting.

Keep messing with it and the full, 100db alarm will go off. Consider this feature a deterrent but not the main attraction; just because an alarm is going off doesn’t mean someone will stop and help. What’s more important for stopping a would-be thief is the same shared design across all the variants.

That means a series of 15. 5cm long, and 5. 5mm thick hardened steel bars.

Each one connects to the next with a shielded joint and there’s a rubberized coating to protect the finish of your bike. If it’s a lock with a key, the cylinder is well protected but, in this case, there’s no lock cylinder to protect. Image 1 of 2The upper has a status light that lets you know when the unit is locked.

(Image credit: Josh Ross) Instead of a lock cylinder, the upper part of the 6500 SmartX features a rubberised outer with silver plastic. The plastic is entirely for show and the rubber is a protective cover that pulls to one side.

Once pulled to the side the cover reveals a coated steel with a USB-C port on the side. In general, it’s very non-descript because nothing actually happens here. Buried in the steel is a battery that lasts for about 6 months of normal use and below the USB port, you can see the Bluetooth antenna.

On the very top, there’s a status light that’s visible through the cover. Red means unlocked and green means locked. There is also an included frame bracket.

It’s one of the things that endears people to the Bordo folding locks in general but in the case of the 6500 SmartX, it’s a little different. The case actually looks exactly the same with a simple holster design and an upper gate that keeps the lock solid inside of it. What’s different is that the weight of this lock precludes the use of the water bottle bosses and instead there’s a system that tightens a bolt against included metal straps.

The only thing to keep in mind is that the included instructions are generic to the whole lineup and make it seem as if the water bottle mounting bosses are usable, they aren’t. Image 1 of 3The weight of the 6500A SmartX means it doesn’t mount to the bottle mounts but instead uses steel straps.

(Image credit: Josh Ross) Security There is some info here that could directly transfer from our recent review of the Hiplok Gold chain lock. This is a Sold Secure rated lock, meaning it’s been independently tested and rated.

As mentioned in that review, the Gold rating means it will take longer than five minutes to defeat the lock using hand tools including large bolt cutters and hacksaws. Also mentioned in that review is that the Sold Secure Gold rating does not test against a portable angle grinder. The reason for that is almost every lock on the market is an easy mark for an angle grinder.

It takes under 30 seconds to cut through the steel bars of the Abus Bordo 6500 but there are some additional considerations for a folding lock. A quality U-lock will require two cuts to open. Meanwhile, a chain lock is challenging to hold still or might be very close to the bike frame.

Those are both challenges a thief will overcome if determined but they do help. A folding lock is the easiest to cut with a grinder as it’s simple to hold it still and away from the frame plus it only takes a single cut. If a portable angle grinder is a type of theft that worries you then the only option we’ve looked at that will protect against it is the Hiplok D1000.

That’s an odd statement for a bike lock but that’s the nature of the Abus Bordo 6500 SmartX. The added cost is about usability and that’s all baked into the app experience. When you get your new lock the first thing you will do is install the Abus app and scan the included key card.

It’s important to know that the key card isn’t a throwaway piece of packaging. You’ll want to keep it safe and secure and treat it as your backup key. Worst case scenario you could effectively reset the lock by adding it as a new lock with the keycard.

Don’t lose it. Once the lock has been through the initial setup, it’s ready to go. Despite feeling like it’s solidly closed in the bracket, it’s actually impossible to lock it with the steel bars folded, since you have to insert the initial bar into the lock farther than is possible without opening the links.

When you are ready to use it, open it up and thread it around the rear wheel, the frame, and your chosen immovable anchor. The internal locked space is much larger on a folding lock than on a U-lock and that’s one of the advantages. It’s not actually as flexible as it initially seems though and definitely not as flexible as a chain.

The last link, which connects to the top, can’t bend past 90 degrees in relation to the top section. Then on the other side of the lock bars, the first bar doesn’t rotate at all. The combination of the two limits makes for a long oval shape.

Still plenty of room but perhaps not quite as expected. Image 1 of 3The inside locking space is even bigger than most chains. (Image credit: Josh Ross)Image 2 of 3There is plenty of room to lock up around a sign post.

(Image credit: Josh Ross)Image 3 of 3There is some limit to the size based on these max angles coming out of the top. (Image credit: Josh Ross) When everything is in place, give the first bar a shove and it will seat into the top. There is a brief pause where you can pull it back out but after that, you’ll hear the motor engage the lock followed by a beep, a green blink of the status light, and a notification on your phone.

In the app, you will see where you locked your bike on a map and who has access to it. You can use that screen to provide access to someone else in your address book should the need ever arise. There’s also a battery level readout.

When it’s time to get back on your bike, open the app and press the icon on the map. Once you hear the beep it’s ready to open. One feature that really increases the convenience is the keyless setting.

You’ll have to dive into the settings, and it’s a confusing name given that there is no key, but what it does is automatically unlock via Bluetooth. As you walk up to the lock, and get into Bluetooth range, your lock can unlock automatically. There are settings for the distance but in general, this is the promise of smart locks in general and it feels like magic each time you use it.

Now of course, I’ve just described how this all works in a very clinical way. Does it work? In my time testing, yes. Using a Google Pixel 4a, then a 6a, it worked just how it’s supposed to and was available for unlock each time I walked up to it.

There were a couple of times I had to force close the app and open it again to get it to acknowledge the lock but this tended to happen when I was specifically testing. If I locked it and walked away, it worked. In one instance, I had to cycle my Bluetooth on and off but that seems to be a Pixel 6a issue.

There’s also the alarm which I thankfully did not get to test in a real scenario. It’s not all that sensitive to hitting the lock and that’s a good thing. What it’s very sensitive to is pulling against the insertion point and when it goes off its loud.

I doubt that anyone would actually do anything even with the alarm going off in a public space but as I said earlier, it can’t hurt. Image 1 of 2When you have it setup for a manual unlock, press this button. You can also see where you’ve parked your bike.

I love the concept of adding technology in a way that increases usability and that’s what the SmartX does.

It’s convenient to walk up to your automatically-unlocked lock, fold it up, and put it into the frame mount. Riding with my son to school and not needing to juggle his helmet, two bikes, the lock, and the key is fantastic. Is it worth so much extra money for that ease of use though? As long as you think so, the performance is fantastic.

If the price is an issue but you like the idea of a highly secure folding lock then there are options available from Bordo. You still get the high-quality frame mount and the convenience of a folding lock. You might also want to consider those other options if you have less love for technology.

My lights turn on with the internet, my door lock is smart, my bikes have no cables, and I’m sure you are getting the idea. For those that prefer a key and no need to charge anything, look elsewhere. If you like the magic of walking up to your bike and having it automatically unlock, Abus makes it work.

Testing scorecard and notes SecuritySold Secure Gold is a high level of security and it means third party testing but there’s no insurance offer. Insurance offers don’t always pan out but it would be nice to at least see it offered. Also, Gold security isn’t the highest offered and folding locks are more vulnerable to angle grinders than chains or U-locks.

7/10Build QualityThere’s no lock cylinder to degrade from moisture but the hinges already feel like they could use some grease. 8/10Ease of useThe magic of this lock is here. Using it feels like the future has arrived.

10/10ValueThis is an expensive lock and there is a big price jump from the standard to the alarmed version. You do get a quality product though and there’s no one else making anything like it. 5/10Overall75% Tech Specs: Abus Bordo 6500A SmartX Price: £259.
