CABLE LOCKS - Lightweight and Portable
Cable locks are available in combination and key form. They are flexible, so they give you more options where you lock your bike, plus they are light-weight and portable. They are ideal for quick stop scenarios, rural areas and on car racks. Many Bell cable locks offer free key replacement and personal combination storage programs, along with bonus features like dust caps to protect against the weather and lighted keys to help you in dark conditions. If you need a higher level of security, you might prefer a U-lock.
U-LOCKS - Higher Security Rating
U-locks have the highest security rating, but how you lock your bike makes a big difference. Small or standard size U-locks allow you to lock your frame only. U-locks with extra long shackles allow you to lock your frame and rear wheel. And for the ultimate security, combine a long shackle U-lock AND a cable lock that will allow you to lock your frame, rear wheel and front wheel. Also, look for our Anti-Theft protection program that offers up to $1,000 if your bike is stolen.

User questions & answers
| Question: | How many keys? The picture shows two |
| Answer: | The picture is right. It comes with two keys. |
| Question: | What Kind of key is i |
| Answer: | Hi,This locks uses a high security key that is not easy to have duplicated. It does come with 2 keys, but if you are needing more than 2 keys you might want to buy another lock.Thanks. |
| Question: | Anyone think it’ll work as a motorcycle lock? I just got my bike and I have one of these locks. Was gonna use it for a few nights until I get one |
| Answer: | Do not use this as a bike/motorcycle lock. It is very low quality, easy to break in to and has a very short life span. Disc locks are just as cheap and offer much more protection. |
| Question: | would this lock be good on a frig inside my house to keep kids out |
| Answer: | I used this lock for a bike. That's it's primary use. But it's strong, and unless your kids can pick an unpickable lock or cut through it with a circular saw, it should do the trick. After buying this, your kids won't be eating any food. Rest assured. |

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: | Does this lock have the capability to lock 2 bikes onto a Swagman bike carrier |
| Answer: | You should measure the distance between the bikes when they are on the rack. |
| Question: | Does this come with the thing that'll let me snap the lock to my bike |
| Answer: | The locks is great I don't like the upgrade and where my bike buy mounted it so not happy with that. He put on side I would still put on top rail on mens bike.the last one I had the plastic broke & the lock fell off while I was riding & lost it after about the 4th time falling. Just keep in basket. The lock is really good and is wide & long enough to fit around almost anything. I would go for it & try to mount the clip on the top bar not the side. If you have a basket just use that. The lock is really good. |
| Question: | What are the dimensions inside the U |
| Answer: | 4.5x11.5 inches. Note that the 11.5" is measured to the longest dimension of the curved end. |
| Question: | how does it attach to the bike |
| Answer: | It comes with a small mount which clamps onto your bike frame and the lock clips to it. You'll find though that the lock is so long, there's nowhere on your bike to fit it. Mine's a fixie and the lock's too long to mount in the frame area, and mounting anywhere outside of the frame obstructs the pedals and my knees. I just hook it over the handlebars now. |

User questions & answers
| Question: | Does this have a flat key lock |
| Answer: | This is a disc detainer lock. It has a semi-flat key with a mostly rectangular cross section with multiple angled cuts designed to rotate the discs inside to specific points. It pretty much looks like this https://i.ytimg.com/vi/I7A3aEgtv_o/maxresdefault.jpg Picking? Man, fahgettaboudit! Unless you leave this locked overnight, chances of this lock being defeated are between slim and none. |
| Question: | Will this fit in a Ulock holster |
| Answer: | Ran into this issue myself. Kryptonite recommends the Transit H-bar carrier for this particular U-Lock. The only New York lock that will fit in the holster is the standard NY lock. Not the mini. |
| Question: | Mounting bracket for fahgettaboutit |
| Answer: | For Road Bike there's this adjustable solution: www.amazon.com/U-LOCK-HOLDER-Holder-Mount-Huldit/dp/B01MZ4GMUW/ |
| Question: | How much does it weigh |
| Answer: | The lock weighs 4.35 pounds and it's heavy. My uncle who uses his bike daily, doesn't use the lock much because of the weight it adds to his backpack. |
