Kryptonite Keeper 785 Bike Chain Lock, 2.8 Feet Long Heavy Duty Anti-Theft Bicycle Chain Lock with Keys for Bike, Motorcycle, Scooter, Bicycle, Door, Gate, Fence

Been using this for a couple of years now with no issues, lock has been good and hasn't had any binding issues which is fairly common leaving locks out in all weather. Only negative is the poor key design, metal keys with thin plastic key ring is very poor, had the plastic break on one key and had to take a 10 mile trip home to get the secondary key....

Like others I found this a little tricky to open sometimes but once you get the knack for it, it’s no problem. It looks great and I think it puts thieves off being red and thick, happy! Bike hasn’t been stolen yet lol

Great lock that is fit for purpose. I use to it to secure my bicycle commuting to work. The lock is long enough to fit around the frame of my bike and the rear wheel which has a 40mm depth rim 700c tyres. I noticed some reviews mentioned problems with the keyhole or rust. Don't force the lock; be gentle with it and keep the keyhole facing towards the ground so that if it rains it's not exposed and this will prevent any rust. I have no issues with this lock. It's very versatile and robust.

It’s a quality product, Feels very robust and the covering on the chain is good, but I was a little caught out with the length. I measured the length I needed, and this appeared just long enough. The measure of length is correct from end to end, but because the chain attaches to the lock in the middle at a hard right angle , not at the end, you lose an inch or more ... unfortunately that meant the lock was just a fraction too short for my original use and I needed to buy an alternative. The quality of the lock is such, that I still kept it and intend to use it elsewhere.

i love it it looks good with my black and red, hybrid, dawes pushbike and keeps it secure. it will never scratch it with the soft cloth casing and is easy to open and close. fantastic buy really worth every penny, especially as it is far more expensive elsewhere, such as Halfords.

It's a really heavy lock and seems strong enough to resist to thieves, although it hasn't been really tested yet (fortunately). Not good to take with you because of the weight.

I used this lock to go through my bucket seat and through my steering wheel as an extra deterrent , looks good also great quality outside casing so Doesn’t scratch of my interior 10/10 would recommend

Such a good lock. I use this everyday to protect my ebike. I use this with another, bigger, heavy duty lock but this is fine in its own for short periods.

Legit! Fast delivery

It's a well-made bike chain and lock! I trust the disc detainer lock to be pick resistant, and in my relatively safe city, the 7mm chain is more than adequate to secure my bike from theft.

Nothing bad to note.

I have 2 locks and have two of these for my mountain bike parked outside at night. It is annoying enough that my mountain bicycle has been safe for more than a year now.

Heavy and durable. Very well made
