Kryptonite New York Fahgettaboutit Mini Bike U-Lock, Heavy Duty Anti-Theft Bicycle U Lock, 18mm Shackle with Keys, Ultimate Security Lock for Bicycles E-Bikes Scooters,Black

It’s really good, it’s really thick so it’s hard for people to steal ur bike which is the point, definitely heavier but worth the money, definitely recommend!

Superb built quality, going on nearly 2 years of use and it's not flinched once. Couple things to note; The plastic sleeve that covers the keyhole is rather flimsy and will likely come off with rough use. This does not affect the function much, if anything it makes accessing the lock easier. Otherwise, be mindful of the spacing your bike has! This is a VERY thick U-Lock and will have much less margin of error than something like a chain or wire-lock.All disclaimers aside, it is one the the sturdiest and safest locks I've used so far. Absolutely worth every penny.

First impression : "This thing is HUGE, HEAVY, how am I ever going to mount this on my bike?"Well, you CAN mount it. Use the Master Lock 8351D Smart Bracket. It works like a charm. You'll pay $4 on Amazon to buy the bracket. When you get it, take out the two screws from the shackle portion of the mount and throw them away. Then go to the hardware store and pay $1 for two M4 30mm bolts. If you use those to mount the hardware on the shackle, it works great. See my pictures, and more info on my review of the Master Lock 8351D Smart Bracket.The lock itself is heavily reviewed on the web - no need for me to repeat that here. BUT seriously consider WHAT you are going to lock your bike to. You cannot use this on a lamp post, and I have great doubts about whether it will work on a parking meter -- the lock is just too small.Check my uploaded images and you'll see the dimensions. I lock it to a very strong street sign at work, but it's a tight fit. You may want to measure your "fixed device" and bike frame and do the math before getting this, and make sure it will fit for you.If I get to try this with a parking meter I'll update my review.Highly recommended - but make sure to buy the mount, and check the size issue before you buy.Well, 1 year later I still have not had occasion to lock this to a parking meter - but I seriously doubt it will work. The parking meters here are just too thick for this to get around. I always pick a secure street sign at my workplace, and the few other places where I regularly ride. This just snugly fits around the post on standard street signs. Please research that issue carefully before you buy - make sure you can verify that it can get around whatever you need at your workplace or park -- it is a SMALL U-lock, but a great one.UPDATE 8/2/16 - six years later.By the way, my mount setup [Master Lock 8351D Smart Bracket.] 6 years later still is working without a hitch - that is definitely the way to go! slides right on the bike, and has never fallen off. And I've finally gotten around to getting a few pics showing the lock at a large handrail at work (1.5" diameter pole), and a signpost that I use every day for my lockup.

If you don’t want your bike stolen, get this lock!When I got this lock, it not only looked like a beast and felt like one, but it also had some serious weight to it. Totally worth every penny—super high quality! With the Fahgettaboudit lock, I feel confident no one can steal my bike. I bought it for my (Lectric) e-bike, and it works like a charm.I also love that it comes with multiple keys and that you can register them in case they’re ever lost or stolen. A quick note: if I’m going off-roading or don’t plan to use the lock, I take it off the bike because of the added weight.Overall, 10/10—love it and highly recommend it!

This lock is extremely bulky and heavy but overall there is no way anyone is breaking it or taking my scooter. I use this lock to lock my scooter on a college campus as I had someone steal my previous scooter with a different lock and wanted to be extremely cautious with a new scooter. Overall, there is absolutely no way someone is getting around this lock. The downside is that when I put it in my backpack, it weighs it down greatly. The lock is not very large but weighs around 10 pounds and can be an annoyance to carry around and is not easy to mount to your scooter while riding since it is so heavy. The lock is easy to lock and unlock and there are many safety measures that would prevent thieves from stealing it, plus it comes with a warranty if your bike or scooter is stolen! Overall great investment for your equipment.

This is highly rated on consumer reports. The lock is heavy and solid. It is a quality bicycle lock.
