Kryptonite New York FAHGETTABOUDIT 1415 Bike Chain Lock, 3.25 Feet Long 14mm Steel Chain 15 Pounds Heavy Duty Anti-Theft Bicycle Lock with Keys, 10/10 Security Rating for E-Bike E-Scooter Motorcycle

Very good quality

I have recently purchased this chain & lock and as soon as i took it out of the box i felt as if i got the right one. It is heavy, solid & easy to lock, unlock. The chain looks treated and Stands out as a serious deterrent. The key has a nice bright blue light that helps in unlit areas at night. Now i thought about maybe giving 3-4 stars but i concluded that the lock itself imo is definitely worth 5 stars so i have given 5 stars. The reason why I considered 3-5 stars is because I ordered this item from koo bikes and it took so long to arrive i contemplated sending it back. It had passed the cut off delivery date. Totally unacceptable. I was very annoyed. So my advice is if you want a solid chain and lock to keep your bike safe, I recommend this one. As for ordering it from koo bikes, fahgettaboudit.

This is a heavy duty lock recommended. It is so heavy, I leave it on my home rack and take a smaller one when I go out. I feel confident my bike is safe with it.

Great product. Heavy, reliable. Likely very difficult for a thief to get through. Note, too heavy to bring on a cycle with you. But good to say, leave one at work or in a bike shed. Pricey though.

Very heavy and well made. Good cover for chain to prevent chipping your paintwork. 3 keys provided but only 1 with a light. I would have preferred the padlock to be attached to one end, not detachable, but there may be a good reason for this for some. Expensive, but cheaper than a new motorbike!

I can't register for warranty on their site, as this is not listed! The chain and lock seem substantial; time will tell. As others state, it is very heavy.

Truly a perfect chain and lock combo. I would say this is the most reasonable chain size you can carry with you for motorcycles to lock up somewhere, but that's not to say it doesn't make a viable permanent ground anchor for your home or work, it's a true tank. If someone has the tools and power to cut through this lock or chain, 99.99% chance they're going to have the power and tools to cut through any other huge chain irregardless of it's size at this point. My only gripe is the lock, the evolution series 4 really does struggle to unlock and can be frustrating at times. That's not to say it's unreliable, it's just time consuming.

Bought this to secure my bikes to my campervan bike rack overnight when we are traveling. It weighs a tonne. Can't imagine any thief could be bothered with trying to break into it, it's insanely chunky and robust. I feel very secure when using this, it would be easier to steal my van than the bikes. However, the down side is that because of the weight we can't leave this lock on whilst driving as it would hang down and bash the rack. Ideal if you want to secure your stuff. Not good if you want a lock that you intend to carry about with you. My priority is making sure my bikes don't get nicked and I really believe this lock is about as secure as you can get so it suits me perfectly.
