Welcome back to another video my name is James from bike lock Wiki and in this video we’ll be comparing Two Sold secure silver rated folding bike locks the foldy lock Compact and the Kryptonite kryptolok 685 as a quick heads up the folding lock compact I use for Destruction testing was one that I’ve

Owned and used for over four years so as you can see it’s already picked up several scuffs from accidental drops and knocks when being used first up we have the basic crop test dropping each lock from shoulder height which is roughly 1.6 meters five times to test the

Durability of the Lux outer shell and to simulate how well it will stand up to wear and tear over the years on the final drop the plastic mechanism cover of the compact popped out this was secured by four plastic tabs which snapped upon impact but this didn’t

Alter the way that the lock worked and I was able to stick it back in place despite the three tabs being broken 685 up next again dropped five times from shoulder height this lock had only been used for two weeks at this point so as you can see it had very little wear

To begin with the plastic casing showed several scuffs and scratches afterwards and I noticed a crack near one of the rivets but the lock still worked as it should do so no real problems here next brute forced Hammer testing using a 1.6 kilogram lump hammer and a steel

Anvil to strike the lock 10 times in multiple locations the compact’s plastic housing took a good battering and as you can see some of the plastic was bent out of shape one of the rivets I struck during the testing stiffened up and upon testing the locking mechanism I was

Unable to open the lock so the locking mechanism must have been damaged by a blow of the hammer still if the lock was secured to your bike it wouldn’t have released and would have protected it from theft here 685 up next which lost its Keyhole cover

And some of its plastic housing on the first few blows the plastic housing deformed a fair amount and one of the locks rivets stiffened up like the compacts did but when tested the locking mechanism was still operational however without its plastic housing in place I did struggle to re-lock the 685 once opened

Next the HSS or high-speed steel hacksaw test which I run for at least two minutes to see how resistant the locks are to a fairly standard hacksaw blade I removed plastic housing from the locks for this test as it provides a better view of the action I’ve attempted to cut

Several of CD locks products with HSS saw blade before without much luck so I wasn’t expecting to make much progress here either and after two minutes of Shoring you can see that the compact hardened steel plates resisted the saw attack very well I changed out the saw blade for a new

One to cut the 685 and as soon as I started cutting I knew this was going to be an easier cut to make the progress made here was much faster and I could see the metal flaking away underneath the blade in two minutes of sawing I was

Able to cut completely through the 685s plate bear in mind however this figure was obtained from Lab conditions using a vise and a fresh saw blade it would be extremely difficult to replicate this style of attack on the street as folding locks are very difficult to hold still

Instead This Test serves as an insight into the resistance and overall quality of either locks plates since the results we had here were so different I wanted to run and test again so I went against the compact for another two minutes producing a slightly deeper cut than the

First attempt with the blade still fairly sharp I started again on the cryptolock 685 and in half the time or one minute I was able to achieve a more substantial cut than I was able to with the compact overall these results suggest that the hardening process for

The foldy lock compact is superior to the Kryptonite 685s for repelling hacksaw attacks now carbide blades are known to be a good way to cut through hardened steel so I like to include a test with a carbide saw blade as well to see how locks perform compact up first and to be

Clear the blade had been used several times before but was still in good condition with most of the tungsten grits still in place on the blade after two minutes of cutting with this my arms were getting tired and I wasn’t able to make a full cut through the compact a

Deeper cut than with the HSS blade however as you can see plenty of tungsten grit left on the blade so I moved on to the cryptolock 685 without replacing it I started cutting but had to re-tighten the clamp as the lock was moving around and after two minutes of

Cutting with the carbide blade this 685 showed similar damage to the compact my arms were tired at the end of this test but I was impressed to see both locks survive against the carbide blade again this method of attack wouldn’t be viable on the street as the lock would be too

Difficult to hold still bolt cutter testing next starting with my smaller 24 inch bolt cutters these are small enough to be concealed on the street and are commonly used by thieves to defeat lower quality bike locks the foldy lock compact up first and after three minutes of awkward struggling I’d

Hardly dented the five millimeter hardened steel plate despite using the ground and my full body weight for leverage after testing I noticed the blades of the bolt cutters had been pushed apart by the force applied when attempting to cut the plates so I readjusted the bolt cutters for the cryptolock 685’s turn

After over two minutes of cutting the cryptolock 685 had held strong against the smaller bolt cutters and didn’t show much more than a scratch I also needed to readjust the bolt cutters again as the drawers had been pushed open a good performance by both here with no

Complaints from me other than my arms being pretty fatigued by this point 42 inch bolt cutters are the largest readily available bolt cutters on the market and are almost impossible for thieves to conceal on the street they’re therefore unlikely to use Cutters this big as you’ll see here they’re also

Ridiculously heavy and awkward to operate I had expected both locks to succumb to the huge draws of the 42 inch Cutters but after another tiring two minutes the compact held strong and only showed a Nick in the plate again the cutter blades had been pushed apart so I

Tightened them back up for the cryptolock 685 from the get-go with the 42 inch Cutters I didn’t have high hopes for the 6a5 but was massively surprised with how it performed both locks were rotating in the drawers of the Cutters hence why you see me trying to keep them still with my

Foot as cutting when the lock isn’t flat will cause permanent damage to the blades upon inspection a small split at the beginning of the cut area on the 685 but it held strong and resisted for over three minutes great performance here from both locks the rivets of folding locks are often

Targeted by thieves as a weak point which is why I don’t recommend the use of low quality folding locks for everyday use starting with the compact I used my 24 inch bolt cutters to attempt to split the rivet by sliding the drawers between the plates the compact’s plates are chunkier around the rivet

Which made it extremely difficult to insert the lock into the drawers of the Cutters additionally the compact uses impressive rivet protection a small steel coil is wound around the river’s armor specifically designed to prevent this sort of attack after nearly three minutes of cutting I’d made little to no progress and was

Unable to get the lock to stick into the drawers with the cutters the crypto lock 685’s plates are the same width along the plate and use one large internal washer to protect the rivet with no outer coil or spring I was surprised at how easily the protective

Washer split under the pressure of the bolt cutters you see a small piece of it fall out here after my first cut attempt with the internal rivet now exposed it put up Little Resistance against the Cutters and the lock popped open since this was a much easier fight than

I had experienced with the compact I tried again to make sure it wasn’t a dodgy rivet and despite it taking slightly longer the same thing happened the internal washer cracked and then the rivet gave way under the pressure of its plates being forced apart taking a look

At the two broken rivets shows us that one was cut albeit not very cleanly by the bolt cutters and the other had one end sheared off from the pressure of the Jaws pressing the plates apart impressive resistance from the foldy lock Compact and a questionably poor performance from the cryptolock 685

Now before we take a look at how either of these locks performed against more advanced tools such as angle grinders and nut Splitters we’ll take a look at how practical they are to use the features they offer and the quality of their design and materials I do recommend anyone interested in either of

These to pay attention to this section as it will help you understand if either of these locks are suitable for securing your bike comparing the weight of the Compact and the cryptolock 685 you can see that the compact is ever so slightly lighter but to be honest the difference

In weight here isn’t noticeable and both locks are suitable for carrying in a bag or mounted to your bike without your ride becoming too uncomfortable shackle thickness is always interesting as it can help us to understand why some locks are more resistant to cutting than others as we found out during testing

Both of these locks held strong against the 24 and 42 inch bolt cutters which was a surprise to me the compact plates measure in at roughly 5.18 millimeters thick and the cryptolox 685s plates measure almost exactly the same at roughly 5.15 millimeters thick both of these folding bike looks and the sold

Secure silver pedal cycle rating the silver rating means these folding locks are suitable for use with medium to low value bikes that don’t attract second looks from passers-by personally I wouldn’t recommend using either of these with bikes worth over one thousand dollars instead you’ll want a more

Secure lock both Brands offer a solid secure gold rated folding lock the Kryptonite Evolution 790 and the foldy lock Forever both offer a higher level of security at sold secure gold if you specifically need a bike lock for an e-bike you’ll want to look out for the sole secure powered cycle rating which

Is found on products like the light lock X1 or the hip lock d1000 as we discovered during destruction testing the casing of the kryptolock 685 was much less durable than the compact and was very easy to remove the casing of the foldy lock compact looks and feels

Higher quality and is likely to show less signs of wear and tear over time both of these locks use a slider cylinder which are commonly found on automobiles and high value items both are resistant to picking methods such as raking and to be honest hardly any bike

Thieves are going to have the skills required to pick a lock in the first place and will almost always opt for brute force or power tool attacks anti-drill plates sit at the front of the either lock cylinder which prevents the locks from being drilled and also provides extra protection against other

Forms of manipulation overall both cylinders offer a good level of protection and this is unlikely to be an area targeted by thieves in addition I did prefer the design of the compact’s locking mechanism since it prevents the lock from flopping open when unlocked whereas I did find the 685 to be

Slightly loose and when unlocked it can flick open potentially damaging the paintwork of your bike bike lock maintenance is very straightforward moving Parts require lubrication to prevent corrosion over time and to keep them moving smoothly so for a folding lock this means a quick spray of white

Lithium grease into each of the rivets wiping away any excess with a clean cloth follow this up with a few squirts of a lock-specific lubricant into the Locking cylinder and rotating the key to loosen any debris from inside and allow the lube to penetrate all of the moving

Parts then using a clean cloth wipe away any excess and you’re good to go I always recommend monthly or bi-monthly cleaning and lubrication as it’s always best to be proactive rather than reactive in your fight against corrosion the foldy lock compact is supplied with three keys whereas the Kryptonite 685

Comes with two both Kryptonite and CT lock offer a key replacement service to their customer so keys can be replaced if new copies are required upon purchase I highly recommend taking note of your key code supplied and taking a picture of it before you start using your lock

This way you’ll have it to hand if you ever lose your keys one key related feature the compact lacks is a keyhole cover whereas the 685 offers a manual Keyhole cover which prevents dirt and debris from entering the locking mechanism reducing the amount of Maintenance the lock requires over time

Both locks are supplied with a mounting system that works relatively well these mounts can be quickly attached to your bike in a few minutes and will hold your lock firmly in place while you ride I did notice the kryptolock 685’s mounting system is quite rattly on bumpy sections

Of Road whereas the compact is silent when mounted but can be stiffed to insert and remove when new locking your bike with either of these locks is very easy now the most effective method is to secure your rear wheel and frame at the same time to an immovable object such as

A bike rack or a street light additionally I always like to use a cable extension with my bike as this allows me to secure my front wheel and gives me some extra peace of mind and prevents opportunist thieves from removing it whilst I’m away whilst a few

Of my viewers have seen baffled by my comments on sustainability when it comes to bike locks there is a lot that companies can do to lessen their impact of their activities on the environment apart from a few single-use cable ties Kryptonite packaging is predominantly made from cardboard which can be easily

Recycled CT Lux packaging is predominantly cardboard but they still use plastic blister packaging on their products which makes it harder to recycle but not impossible Kryptonite talked briefly about sustainability on their website and in a bit more detail on their parent company Allegiance website CT lock don’t really mention

Sustainability and are a substance actually smaller company than Kryptonite I do feel overall that both companies should be doing more to push sustainable manufacturing especially a company like Kryptonite who have an opportunity to lead by example here when it comes to warranties it’s nice to see that both of

These companies stand behind the quality of their product the foldy lock compact is supplied with a three-year warranty which is activated when you register your keys on their website whereas the Kryptonite 685 is supplied with a 10-year guarantee on materials and worksmanship 685 up first and after two

Minutes I only managed to split the locks protective washer despite loosening and reattempting the cut the nut splitter was too tight to turn further and I gave up the compact went into battle second and provided similar resistance to the 685 its internal rivet protection clogged up

The way and prevented the blade of the nut Splitter from making contact with the internal rivet by this point I’d spent nearly three minutes tightening the nut splitter before giving up to my surprise upon inspecting the state of the rivet up close it gave way under the pressure of the nut splitter reminding

Me why I always wear protective equipment when conducting these tests I really wasn’t expecting the compact to break during this test since it resisted the side cutter attack so well good performance from the 685 and a narrow fail from the compact it is worth mentioning that it would be very

Difficult for a thief to use this method of attack on the street as tightening the nut splitter requires two hands so they’d struggle to hold the lock still for this reason nut Splitters are also not as common in a thieves toolkit as a pair of bolt cutters

Angle grinder testing up next and before we begin I wanted to point out that neither of these locks are designed to resist power tools any bike lock without special anti-grinder features can be cut quickly with an angle grinder and to provide comparison to the results shown here I’ve cut through the Kryptonite New

York standard d-lock which is 16 millimeters thick and offers these sold to kill gold pedal cycle rating for accurate representation I cut through the New York lock four times giving us an average cut time of 15.7 seconds now to find out how either of our folding locks compare the cryptolok 685 up first

Which cut faster than I was expecting over at six Cuts providing us with an average cutting time of 6.11 seconds again it’s important to remember that these times are obtained from Lab conditions using a vice and a top quality angle grinder on the street a thief would have to cut one-handed using

Their other hand to stabilize the bike lock making it significantly more tricky compact next which took longer to cut than the cryptolog 685 and put up a reasonable fight providing an average cut time after six cuts of 10.07 seconds these times are substantially different which could be due to the fact that the

Crypto lock 685 is the same width the whole way down whereas the compact starts wide and gets thinner in the middle of the plate this also suggests to us that the 40 lock compact uses a higher quality steel for its plates that’s more suitable for use with anti-theft devices to summarize both of

These locks performed well during destruction testing overall I’d say that the foldylock compact came out on top in terms of security it resisted the 24 inch side cutter attack and the HSS soar attack whereas the 685 felt significantly easier to cut with both I also prefer the overall look and feel of

The compact as well it offers nice features like the silent mounting system and its locking mechanism which doesn’t flop open when unlocked as always I’ll leave key details and links to either product in the description down below I hope to have answered all of your questions if not leave me a comment down

Below and I’ll get back to you thanks for watching and I hope to see you in the next one
