There is something about major metropolitan city people that instantly responds to a bike – any bike. I’m not sure if it’s some kind of collective nostalgia about simpler days and times or if it’s about the mechanical age that promises a mode of escape from the crowd that constantly surrounds us.

Regardless, show a city kid a bike, close your eyes and magic happens – it disappears.

Kryptonite, the maker of this locking system, has been around for quite a while and has developed a deserved reputation for quality products and excellent customer service. The Kryptolok Series 2 U-Loc system is one of their lightest weight locks coming in at about 3.2 lbs.

One thing to know is that the company does specify that the cable that is part of the system should only be used with this lock. I suspect that has something to do with the warranty.

Open the package right away and register the keys with Kryptonite immediately! They will replace your keys for free once and for a small fee after that.

Because the interior space is high and wide enough, I do know people who have been able to lock 2 bikes together at the same time. Of course, it depends on the type of bike you own and what you are securing it to for this double use will work for you. The cylinder lock is only on one end of the u-lock so you’ll need to pay attention to which side of a post your bike is on.

This is not the lock you want to buy if you live in New York City, Boston, Chicago or Los Angeles where bike thieves are a business all of their own.

But, if you live in upstate New York, suburban areas and other areas where stealing is not the predominant method of acquiring a new bike, this lock will work very well for you. If you are unsure about how much bike theft there is, buy a wheel locking system and use both.

What people said about Abus Mini 140 U-Lock

When I visit to my grandmother’s house in Newport, Rhode Island, I don’t need a bike lock that’s going to keep Houdini away but I do prefer one that will stand up to the possibility of corroding in salt air.

I keep this lock at her house so that I’m not forgetting it at home.

Even though it sounds like the interior space is awfully small, it is big enough to lock the frame of a bike to a round bike rack. No mount is included but it can either be bought separately or you could do what my neighbor’s son does: At only 2.2 lbs., put it in your backpack.

You need to purchase your own cable to secure the wheels to the lock, but in a way that can be a better option since you can choose the length you need instead of being stuck with one that is too short.

The locking mechanism is both smaller and thicker than the Kryptolok Series 2 (above) which can make it more difficult to cut. But, that same feature can also make it more difficult for those with big hands to lock up – depending on the situation.

This is one of the best bike locks for small city or large town use but since I live in New York City, I would use extra locks to inhibit temptation.

I figure it this way: the longer it takes for a thief to break a lock free, the better chance he/she has of getting caught.

When it comes to bike locks, this is my personal favorite! Of course, living in New York City, the need for a method to shackle my bike to a permanent fixture is mandatory - if I want to find it where I left it five minutes earlier, anyway.

I stress permanent because it’s a well-known fact that you can tell someone is a tourist when they lock their bike to a bike rack in front of any store. There are actually thieves that will scout out these racks and lay in wait until several bikes are tied to the hitching posts and then load up the rack, bikes and all into the back of a pick-up. At that point, it doesn’t matter what kind of lock you own, it’s gone with the wind.

In any city, image is important to success and that includes the locking device chosen for your bike. This particular bike fettering system exhibits an image of strength. It deters thieves because it is one single piece of metal that goes from wheel to wheel around the fixture it’s tied to. It’s sleek and shiny and perfect for the professional geeks and sassy divas.

City dwellers know the power of flare and flourish in doing anything. Waving the bow of this locking device around in mid-air prior to hooking it up to the nearest lamp post is one of the recommended styles of bike locking procedures.

If you are looking for a bike lock for campus bike racks, get the 30” to be sure that it will be long enough. The Velcro cinch straps are to secure the bow to the tube on your bike when not in use and the locking cylinder can stay on the bow. Neither one will fall off as you ride, by the way.

Whatever you do, do not lock or unlock this device near a drainage grate. Keys have a nasty habit of slipping from cold fingers and diving directly into the nearest drain! You only get 2 keys and because this system is made in Germany, getting a duplicate is next to impossible!

I suppose I should mention that there is a learning curved involved here when it comes to getting used to locking and unlocking it. Don’t despair! It’s a short learning curve.

The guys that designed this one must have had a few bikes stolen and wanted to be able to identify any thief that took off with their bike – they’ll be the one with the sudden hernia!

Anyone that owns this lock will tell you that it’s heavy. No, it’s not heavy – it’s onerously weighty! It comes in at just a touch over 15 lbs. and 18 mm translates to about ¾” thickness for each link. A lot of people look at this lock and their eyes stop blinking as they try to imagine what tank this came off.

Few people ever notice the U-lock device with the double locking method because they never follow the chain that far (or because by comparison, it looks small). But, the lock is just as strong as the chain and keeps the chain together while you’re out of sight.

If you can afford to take the anti-theft insurance protection, it can’t hurt. Of course, there haven’t been any reports thus far (over 4-years) of theft – but you could be the first.

And, if you have a really expensive bike (scooter, motorcycle, snowmobile, tractor, 4-wheeler), the last thing you want is to be the only one who ever had the bike stolen while hitched up with this New York Fahgettaboudit U-Loc!

There is another advantage to this heavy-duty chain lock: it can become a ninja warrior weapon against experienced city muggers. Of course, that presupposes you can lift it and swing it in case of an emergency. If you aren’t sure what 15 lbs. feels like, pick up 3 bags of sugar and carry them around a store in one arm for a few minutes.

Primarily, this device is designed for moderate to high-theft areas such as major cities where bikes are taken for the sake of commuting. For those who live outside the city, this lock would be good for storing your winter vehicles in summer and vice versa or for securing a bike to a trailer or rack that is not on the top of your vehicle.

If there is one single locking system that deserves the title of Best Bike Lock Ever made when based solely on theft-prevention, it’s this one.​
