Kryptonite Keeper 785 Integrated Chain Lock

As a long-time Kryponite user, I decided to buy this chain for my wife's e-bike. To date, the biggest issue I have is the chain is too short. I read a review somewhere noting this issue, but went ahead and bought it, as we were leaving on a trip. Additionally, I am not especially thrilled with operation of the locking mechanism. My suggestion if you are looking into a heavy-duty chain-type lock, get the longest chain you can, longer than this chain.

The lock is flexible, so it can easily fit around a tube, wheel, and whatever you're locking it to. A chain lock is fairly easily cut, so don't count on this being high security. I left mine chained to a bike rack at work that was well covered from the elements, but after a year, some of the parts on it began to rust from humidity. The locking mechanism progressively started going bad, so I hosed it down with Tri-Flow every few months, which helped. It's now at the point that it takes up to five minutes of fiddling to get it to open, so it's dead.

It�s definitely burly enough that I trust my bike to stay safe for an hour or two while I run errands. It�s pretty heavy though and the chain format is hard to carry wrapped to the frame or in a Jersey pocket� it has to go in a bag or backpack.

This lock is good for what I need. Lower crime area, locking up the bike during a meal at the boardwalk or my local lunch spot. Easy to carry either wrapped around bars or simply worn over shoulder like a messenger bag. The nylon outside keeps from getting pint damages.

Needed a fast way to lock my ebike when it's out of my sight.

Having had my bike stolen I wanted something more robust to lock it up when out shopping. I found the length to be too short to go around your average telephone pole without putting the bike right against it. In other situations, it was just too short to lock it up.

In all a nice lock if only the chain were longer.

I was looking for a mid rangepriced lock to keep my bike on my patio. As it is not in the street I didn't go for a heavyweight one. It looks massive which is a good thing that can deceive thieves. It does not click-lock, you have to use the key to close it. The lock area is not very robust. It is a good value for money lock. I wouldnt use it to lock an expensive bike on the street but it would work great for a not too expensive bike.

Would recommend and would buy again.

Bought this as a back up to my bike rack lock. Works great!

Heavy but very sturdy and can lock any bike. I used it to secure bikes to the cars roof rack during a long trip

I bought this lock to replace my old cable key lock.

For the price, this is a great lock. Less expensive than U-lock with the same safety, and more length to use on your bike I have found this to work great.

The outer 'housing' on the chain will not scratch paint, the track bike I use it on I custom painted myself and is one of my gems.

Down side I have heard from others using this lock, it is heavy, but I have never minded.

Not too heavy, but much sturdier than the typical rope lock.

Solid lock, that even looks great. It's easy to use, although I now must carry another key on my chain. Length is great for one bike, but challenging for our two bikes. We have to position them just so to weave the chain into the typical bike rack. For now, the Kryptonite serves as an excellent repellent for would-be thieves and we bolster it with another longer cable lock, giving rise to yet another key on my chain. Having had our bikes fall victim to downtown bike thieves, we are glad to have the benefit of Kryptonite.

I like this lock a lot. It's not as cumbersome as the NYC big lock

- It's not as long not as heavy

- The lock is integrated so there's no separate padlock

- It's cheaper!

Due to the shorter length, you're not able to lock both wheels to frame without taking one of the wheels off. This seems like a worthy compromise to save on weight and size from the NYC lock.

I appreciate that the fabric cover protects from scratching the frame.

The security rating is technically lower than the NYC chain BUT to the common criminal, I would have to guess that just the looks alone say, Don't even try it scum bag.

Having a thick link chain lock makes me worry less. I use this chainlock when I need that extra security.

We all know that no lock is safe, but for this price, this lock will make the bad person think twice.
