Today we are going to take a look at the Master Lock Quantum Self Coiling Combination Lock, Part Number 8122D. This Master Lock cable lock features a nice convenient and easy to use cable lock that lets you set your own combination for quick recall and ultimate security. There are no keys so you won't lose them and other people can find them to unlock your lock. This makes a great cable lock to secure your bicycle when it is not in use or you can use it on your trailer securing tool boxes, generators or ladders or any other cargo you may have. The flexible braided steel construction resists cutting. It also features a nice protective vinyl covering that keeps the cable from scratching your cargo. The cable lock is 72 inches long by 1/2 inch and features a limited lifetime warranty. Here is our Master Lock Quantum Cable Lock. As you can see, it's self coiling so it's going ahead and self coiling itself back up when not in use or when you have it securing your items, you are not going to have a lot of excess cable.
Graded cable on the on inside that has a nice vinyl coating so it is not going to scratch up whatever you are securing. The lock features a 4 number combination lock that you can go ahead change to whatever you want. You put your code in, it separates. When you are ready to secure your item, put your lock back together. Rotate the numbers and it will lock it in to place. Another nice thing about this lock is that it comes with this bracket that you can take apart and you can secure this say to a bike frame.
It will wrap around there. You can secure it. This part secures to your cable. We are going to go ahead and put our bracket on to our cable lock. There is two flat head screws here on the back of the part that comes off the bracket.
Unscrew that. Once you undo your screws, you can go ahead and separate that. Hold on to your screws. Go somewhere in the middle of your cable lock. Put it around your cable lock. Put this back into place and then tighten your screws back down.
Now that is secure to our cable. Now we can go ahead and secure this to our bicycle. We have our bicycle right here. We are going to go ahead and secure our bracket to it. This has two straps that come around. They will get fed into here. You will just use a small flat head screwdriver. Tighten those down and it will tighten this to your bike frame. Once you have done with that, you can go ahead and cut off the excess if you are going to leave it on this bicycle. We will go ahead and take our cable lock here with the bracket we installed on it. It will slide into place and that will hold our cable lock nice and secure so when we are going down the road, you don't have to worry about wrapping it around your bike frame or whatever. It is secure here with your bracket. When you are ready to hook your bike up, all you have got to do since it is self coiling, just pull it around whatever you are hooking up to, pull around your wheel. Then your bike is nice and secure. Now that we are finished riding our bike, we will go ahead and put our bike in the stand and lock it up. Now our bracket here on our bike does slide out of it. As you can see though, it is around the frame of our bike so even if it does get slid out of the bracket, it is not going to go anywhere since the cable is around your bike frame. That is another added security feature with the bracket here. Once they are on the frame, your cable lock is going to secure your bike even if your clip does come undone from the bracket. That will do it for our look at the Master Lock Quantum Self Coiling Combination Cable Lock, Part Number 8122D. .

Convenient and easy-to-use cable lock lets you set your own combination for quick recall and ultimate security. Flexible steel cable has scratchproof vinyl covering so that it won't damage your bike, toolbox or other valuables.A very hefty cable for sure. My planned use is while traveling with my bike on a carrier, and only when on the road, not left out at night. I'm routing it through my bike's frame, just above the bottom bracket, and then through one of the safety chain loops on my hitch. That way it helps to secure both the bike and the carrier. I've only used it once, and I'm hopeful that it will at least deter theft, since nothing will prevent a thief from taking someone if he wants it enough. The coiling feature is both a plus and a negative. The plus is that it takes up the slack and keeps the cable tidy on the bike, and when storing. The negative is that it makes it difficult to route at times. I also find hooking up the lock to be difficult when the cable is stretched out long, because of the angled way the cable attaches to the lock (and the coiling). If it came together in a straight line it would be easier to work with, at least for me. I understand that it was made this way for its intended use of carrying on a bike when not in use.
The mounting bracket broke on the first ride. Had to wrap the lock around the handle bars
Here is my setup using the items from my two orders, including the two ant-rattle devices. The pictures aren't that great of quality, since I just used my cell phone (my only camera anymore). Everything works perfectly.
GREAT CABLE LOCK FOR THE $.
l LIKE THAT YOU SET YOUR OWN CODE #.

WORKS GREAT SO FAR.
I first talked to Sheri, then the next day I talked to Susan
Both of these girls did a amazing customer service.
Customer Service is a great step to have customers coming back.
I will also spread the word about E Trailer, I have a lot of contacts who bicycle
and they would need a Hitch and a Bike Rack, etc , etc.
Again Thanks for both girls Sheri and Susan they listened to me and knew what
I wanted. I was so surprised to see UPS coming down our driveway about 3 days after I put my order in!!!!!
Love the lock. Solid build and nice to not have one more key. mounts to the bike nicely and should be able to lock up all four of our bikes when we go out exploring.
Nice length, solid, easy to set combination. It's intended for locking bikes to tow hitch if we stop for a meal on the way to or from the trails. It looks kinda big for riding with it clamped to the bike, but if I try it, I'll update the review
Very sturdy cable, which is good. However, it causes the lock numbers to bind when you try to spin the numbers
The lock is a great lock. Used it for the first time today. It was easy to set my own lock combination. And quickly locked two bikes to a bike rack.
Wheel hoop fits our bicycle rack perfectly. Even though we didn't have company name on bike rack. The picture of the bike rack was same. So thank you. Bicycle wheel will sit evenly away from pavemnt previously used bunji cords for losthoop.
etrailer did a fantastic job in every phase of the purchase and delivery. I highly recommend this company...
Easy to use. I am very happy with this bike lock
This is a great lock for bicycles, large enough to secure two bikes at once top quality product at a reasonable price point.
Great service and item description, fast delivery and just what I needed, quality products as always from etrailer!
Great lock. Sturdy - meeting my needs. Love the resettable lock feature.
Everything I expecting it will work good for what I ordered it for. Only negative the part is that part that fits to the bike was missing doesn’t affect me I bought it for another reason but picture needs to be updated if it’s not supposed to be included.

Still work great
Still using it after a year. Has held up great. Would order from this company again.
Thick cable, easy to set combo, works well. Note: the package contains California warning regarding toxic components in priduct.
Had to go on line cause I couldn't figure out how to separate the cable holder. Then felt really dumb. It was so easy.
All the products came as advertised and are all top quality!
Excellent products, received on time.
Haven't used yet but, love the quality and size.

Havent used it regularly, but have taken it on two long overnight trips. Works fine, even after being subjected to driving in heavy rain for many miles twice. The positives and negatives mentioned before still hold true.
