  • Lock it and FAHGETTABOUTIT!
Size: Mini Style: U-Lock Pattern Name: Bike Lock
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. ... show more

Awesome. They may steal your bike. But they will need a lot of time and tools to do so. Worth the money.

  • Excellent shipping times product is very durable
Size: Mini Style: U-Lock Pattern Name: Bike Lock
Okay so I just ordered this yesterday and somehow it was delivered to. So you get a temp 5 star for now because next day shipping is an A+ especially during covid 19 lockdowns. I will update this review in a few weeks and again in a couple months. So firstly this lock comes with ANTI Theft insurance type protection for 1 year free or $9.99 for 2 years now its important you register your bike within 30 days of your purchase this is very important if you want the insurance like coverage. I only ordered my bike today butI recieved this item today so I called to find out. Now I watched several reviews on this particular lock and literally uts damn near undefeatebale without making a ton of noise or being a pretty damn skilled locksmith with specialty custom lock pick tools, although from what I've read the locking mechanism is not the best there is im but it's not bad either from the many reviews I've gone through. Out the box everything locks and unlocks smoothly and it comes with 1 led light key and 2 backup keys the lock and an instruction manual for the lock and w mm1 for the key. Be sure to register your key incase you ever lose yours. I'll review this again at a later time ... show more

  • I love this lock!
Size: Mini Style: U-Lock Pattern Name: Bike Lock
I had my motor scooter stolen last year. The thief cut the u lock I had on it. So after looking at many reviews I decided to go with this one and a 16mm chain so now the weak point in the slightly "smaller" chain lol. This u lock is massive and very heavy so keep that in mind. But it does fit under my seat with plenty of room for gear. After owning the lock for over a year and having it out in the rain and extreme hot/cold it still functions as if it was new. I do put a drop of 3 in 1 lube in the key hole every few months but its has never given me trouble like other disk detainer mechanisms I've had in the past. This lock also has the updated core that has more disks and they tension off a disk father in, instead of the first disk making it harder to pick. But honestly nobody is going to be picking it. ... show more

  • solid
Size: Mini Style: U-Lock Pattern Name: Bike Lock
This things seems solid. Lost a star because it is super heavy and kinda small. (I can’t lock the frame and the wheel - just frame to something.) I think it’s small on purpose but it doesn’t suit my needs. I do feel good about my frame never getting stolen : )

  • Medium-HULK lock
Size: Mini Style: U-Lock Pattern Name: Bike Lock
My BA bike lock. I live in a moderate to low crime area. This keeps the people with substance abuse struggles from stealing my bike. "A lock keeps an honest man honest" They can be stolen (just like the best vults can be broken into with enough time) but it buys you time and is a big pain. This lock would also not feel good against your head. Nice heavy solid lock. It's not super long so with the bike spot architecture you can lock to it but you need to be touching the tubes. If you are 2" away the lock can't go around your frame and the bike stand area. Remember extra space means more options to cut it also. This fits tight but fits! It is NOT long enough to go from my back wheel to my frame to lock it in. I ride a regular petal bike with larger sized wheels and the gap is a bit far. I have to use my long center top tube or large vertical fromt tube to secure it to bike stands. FYI ... show more

  • Very durable lock and easy to carry around
Size: Mini Style: U-Lock Pattern Name: Bike Lock
This lock is a huge step up from my old random chain lock I had. The lock has 3 keys total making it very nice in case you lose any and the product feels super secure. I trust this lock to protect my electric scooter for when I take it to school. The lock has some weight to it but nothing that would be considered crazy. I’ve been using it for around 2 months and have zero complaints. The price was a little steep but after using this lock it feels entirely justified and worth spending the money to protect my electric scooter. ... show more

  • Kryptonite New York Fahgettaboutit Mini Bike U-Lock
Size: Mini Style: U-Lock Pattern Name: Bike Lock
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! ... show more
