User questions & answers

Question:	How does the holder work? How easy to select the combination for open/close (do the dial rings move easy/smooth
Answer:	The holder works well but you may have to use another type of liner depending on the diameter of your top tube. Mine was too large for the provided liner and too small without so I had to"rig" it myself. That was really no problem in my opinion though. I have only set the combination once and have not had to reset it, but it works easily enough. Overall I am pleased with the setup and would recommend this product.
Question:	I only have the use of one arm. Do you think it's possible
Answer:	Absolutely, I have a friend with only one arm who can easily work it.
Question:	I just recieved this lock with NO instructions I have no idea what the combination is how do i reset this please
Answer:	I also had no instructions and 0000 did not work, search on line on how to open a 4 digit lock. This worked for me I figured out the combo in less than a minute !!!!??? then set your new combo. It is easy
Question:	is this Lock trusworthy to use
Answer:	No cable lock(regardless of size) will stop a bike thief, cable locks are to stop opportunistic thieves that take an unlocked bike only.

User questions & answers

Question:	Would this be suitable for an e-bike
Answer:	Yes, absolutely! Kryptonite offers a protection guarantee up to a certain dollar amount based on the type of lock you buy. This lock has a $2,500 Reimbursement limit. I use this lock on my personal Electric Bike Company ebike and love it!
Question:	The dimensions are 3.25” x 7”. Is this the space available inside the shackle
Answer:	The maximum width (at the closure bar) is actually 7 1/2" . The shackle inner (between legs) dimension is 4 1/2".
Question:	How can I transport this lock when I'm riding? I can just hang the round part on my handlebars and put the base in a bag on my back, right
Answer:	my mini-6 did not come with an inside-frame mounting bracket, although I was told it would. The stock part of the lock is a bit fatter than many locks. If someone has a link to which product on Amazon fits the evolution mini-6 perfectly, and knows that from experience, please post it. I went around locally and could only find the "H" bracket which is used to mount on the handlebars, which my bike cannot do as it has an older bent style of handlebar. I would love a link to the regular bracket for mini-6 that can go inside the frame on the same post as the seat, opposite where the water bottle usually is. You know, the place most people mount their locks.
Question:	Is this lock part of the atpo anti theft program
Answer:	It is. But it’s nearly impossible to file a successful theft claim. I wrote about my claim experience here (still no response from Kryptonite): https://twitter.com/wayneyhuang/status/1050850776757743616?s=21

User questions & answers

Question:	Mine came with a serial number. What (how) should I do with it
Answer:	Mine only has a number on the keys. I suspect like cars it allows initial duplication once you know the master number.
Question:	My son immediately lost one of the keys and now I'm living in fear he will lose the last one. Can I get a duplicate key
Answer:	There is a number stamped on the key. Should be able to contact the manufacturer to get a replacement
Question:	Is this a good lock for New York
Answer:	NO, it hefty U bolt lock is too small to use alone and the cable is an unruly mess that any decent bolt cutter can cut through unlike the U Bolt which would even slow down a reciprocating saw enough to stop a thief. The key lock design is pick and drill proof enough to not worry about even in NYC. MIne is on a $200 bike and I have never had any package stolen but I used to live in a bad neighborhood in Chicago. It is more like they would cut the weak cable and then lift the WHOLE bike and cut off the u Bolt once safely in their "lair". Since leaving Chicago I lave has no package stolen in about 30 years. I have had plenty undelivered by ONTRAC which Amazon no longer uses but that is another issue. I know this because I have 4K cameras everywhere that evidence whom is at fault. ONTRAC is the worst delivery service ever.
Question:	Does it have a cancer warning label ? I’ve noticed many locks do
Answer:	The plastic tube surrounding the steel cable may be made of PVC. A law in the state of California requires a warning label for certain chemicals. The label is standard: "This product contains a chemical which is known to the state of California to cause cancer, birth defects or reproductive disorders." It's called the Prop 65 Warning. PVC contains chemicals called phthalates, which mimic the effect of estrogen in the body. On a bicycle lock, exposure is not such a big worry. In a catheter or IVC tube, yeah.

User questions & answers

Question:	How to rotate the set knob 90 degrees to the right per the instruction. It wont budge
Answer:	Please set the right combination at the line with arrows first, and then you can rotate the set knob 90 degrees to set your own combination. Thanks!
Question:	how much does this 6ft lock weigh? description says 2.17lbs...but why does the 4ft one weigh only 0.7lbs? why is this so much heavier
Answer:	I don't know why the 4ft one is so much lighter but I can tell you that this one is heavier because it is very secure, flexible but at the same time you can tell that it would be tough to cut or break. As far as security, you will feel confident that it is really protecting your bike. If safety is your primary concern, don't think about the weight
Question:	Whats the difference between type 1 and type
Answer:	Type 1 and Type 2 have different design of the number dials, but their length, functions and using ways are the same, you could choose the most suitable one by your preference.
Question:	How easy is it to uncoil the chain to use? It looks like it would spring back quickly when trying to fit it around the bike to lock it
Answer:	Yes, the recoil action is very swift, and when the cable recoils, it snaps back hard. Getting hit with the lock end is not fun. The cable wants, forcefully, to stay coiled. Also, the cable twists, so aligning the combo end and the insert end takes determination. Using this cable lock around a typical pipe-type bike rack is okay, but not easy. Using a telephone pole or similar thing (tree trunk, e.g.) is a challenge, especially if you do not want to hug the pole. Finally, this: in dim light or darkness, the numbers are hard to read. You definitely need a flashlight, so a third hand/arm is helpful if you ride evenings and/or nights.

User questions & answers

Question:	What amount of weight can be vertically lifted with this cable
Answer:	The Master Lock 72DPF 15’ x 3/8dia. Cable is not rated for weight suspension. Although the cable is heavy duty and has great strength, the end loops are not designed for suspended weight. The cable should only be used for passive security where no stress force is applied.
Question:	What is the width of the plastic part where the loop meets? It says master lock on it. Thanks in advance
Answer:	Probably about 1/2 of an inch, BTW this lock is amazing and totally worth the buy.
Question:	Will the loop ends fit through kayak scupper holes
Answer:	It appears as though the kayak scupper holes are too small for the loop end to go through. An adapter that will go through the holes should be used with the cable, that way the superior strength of the cable can be utilized.
Question:	What's the diameter of the yellow tubing
Answer:	Mine doesn't have any yellow tubing; sorry.

User questions & answers

Question:	Why not just use a padlock with it
Answer:	As far as "easily cut", no, a good quality padlock can be much harder to cut than this cable. You COULD use a good padlock, but since this cable is meant as a supplementary lock for a wheel or accessories you are presumably already using a U-lock, so it's easiest to just loop through that than to carry a separate padlock + key.
Question:	How big are the loops? I'm wanting to use on kayaks by sliding them through scuppers. The scupper hole diameter is about 1 inch. Will they fit
Answer:	Probably going to have issues. The loops are big enough that you can feed them through each other. You might be able to get the loop through a 1 inch opening but its going to be difficult. This wire is pretty thick, you will likely be better off reducing the size of the wire for your purposes.
Question:	Can i use this with the Kryptonite New York Noose
Answer:	Sure. It is plenty long enough and the loop connects into the kryptonite disc lock easily. You would use the Kryptonite Noose around the frame, rear wheel and a post. The cable would be around the front wheel looped into itself and the the end loop would later be in the disc lock. Use the chain over the cable for locking up the rear wheel as the chain is much stronger.
Question:	Is this compatible with the Fahgettaboudit
Answer:	Yes it is, but. . . the heavy chain that most Fahgettaboudit locks come with would be much better. The Kryptoflex cable can be easily cut by any thief.

User questions & answers

Question:	Can it connect my wife's thoughts with mine together? There will be no arguing about trifles
Answer:	No sadly. There's no understanding a woman's thought process.
Question:	Can 2 or more of these locks be connected in series to form a longer one or is "key" end unique to each so won't fit into "barrel lock" end of another
Answer:	This is a very good question. I deliberately removed two locks for testing, carefully looked at their shape, the shape is the same, so multiple can be connected in series, after testing is also possible.
Question:	When i set up the lock and picked a combination. of course i didn't write it down so i forgot it. what can i do
Answer:	Set combo to 00000 to open. Rotate set knob clockwise. Set your new combo. Rotate set knob counterclockwise.
Question:	my lock will not unlock. I put in my set passcode but still will not open. Anyone have issues with this
Answer:	It just happened to me. I set my own password and it won’t open. It seems like reset knob is so loose so when I lock my key, it turn itself and set password whenever the code I locked. It sucks. Anyone has idea to unlock?
