 Super strong lock with onboard securityMay 09, 2007
By D. Herd
"thehumble1"
I have purchased two of these and love them, so much so that a friend was looking for a lock and decided to get one too. They work great, provide professional level security and still have the flexibility to get around the odd shaped things we have to lock to in a city. Here's the P/C.
Pros:
-Super strong locking mechanism.
-Lots of keys
-Rubber coated so it won't scratch your pretty bike
-Tempered steel jacketed cable to add another level of protection (this thing is great, the braided steel rope has scale like links around it to reduce cutting and sawing attacks)
-Pick-resistant lock
-Flexibility and enough length to get around big lamp posts or a couple bikes.
-non-conventional so thieves with car jacks and crow bars might not be familiar with how to get into them.
-you can sling it over your shoulder (or possibly around your waist).
Cons
-Weight... a lot of it.
-The anti-pick lock makes it really hard to use, you have to develop tricks to get the key in and out, though it's probably worth it versus getting a new bike
-No bike mount. This is crazy. A lot of other products by OnGuard have mounts, but this series of locks doesn't. It weighs a ton in your pack and can't be clipped to the bike. This is hopefully something that will change.
-Cheap plastic pieces. the face of the lock and the short sleeve at the end of the cable (both cosmetic, not functional) are easily broken
-Keys are huge. They have this big M feel to them, taking up a lot of room on a ring. Come on people, let's not self-aggrandize, let's make it user friendly.
Overall: A- I could get by with everything else if there was a bike mount.

Great lock, backed by solid supportJun 06, 2008
By P. Antoniades
I have had a Rottweiler lock for over five years now, and will agree with the two reviews above mine - this is a fantastic, well-made lock (albeit heavy). I haven't ever wanted for a frame carrier - I usually sling it over my shoulder or in my bike bag.
I park my bike outside year-round, and three years of that got to wear on my lock - it was pretty hard to get the key in (as the reviewer above noted). I have since found out (via product documentation :-/ ) that a few drops of oil in the key slot cures this, but the first time I called the company.
Three years of New York winters, I was prepared for "get a new lock". Instead they said "our new locks are better at handling this - we'll send you one free".
That was two years ago. I recommend these locks to everyone, and nobody's complained (or had to call the company). But good to know they are so responsive if you do!

Great, great locksFeb 28, 2008
By Carlos Sosa Martinez
I got a couple of these locks, thinking they were on the expensive side, since they were only locks, but I come to find out that they are more than that. The longs themselves are heavy solid, almost even descouraging to look at (if you were a thief)They are long enough to go around big trees in case you don't find a proper place. They come with a set of 5 keys, and one of them even has a LED light so you can open your lock at night. They also come with a good warranty and the company, in case you loose your keys. (comon' there is 5 of them, I am sure you won't keep them in the same place) there is a small card with a number, you can send that number to the company, and they will replace your keys for free. it is just great. At first they seemed a little stiff and I had a hard time bending it around stuff. But with time they lock became more flexible and maleable, right now it takes me less than 20 seconds to secure my bike to whatever. I am studying in a university in mexico, and bike theft is the order of the day, These locks are exactly what you need in such cases, or if you want to protect your bike. Note: these locks are really heavy, not recommended if you're going biking for a long time or trail. they will tire you out. But if you're like, a student that will like his bike to be in the same place when I blink, and be confident that no one will steal it. buy it. These are simply the best locks.

Captive key; difficult to relock for travel when coiledOct 28, 2010
By David Brown
"(one of thousands of Dave Browns...)"
No complaints about its function while on the bike; it's a fine medium-duty lock.
I don't like the way the key can't be removed while the lock is open. With my previous cable lock, you could take the key out as soon as the lock opened and then lock it without the key. It's a pain to coil it up with my too-large keyring dangling from the end.
Getting the tip of the cable aligned with the lock mechanism to coil it as shown in the image takes a fair amount of forceful pushing and twisting to get it just right. Perhaps this will loosen over time. Or maybe I'll figure out what I'm doing wrong.
Both of these "complaints" probably speak to the solidity of the locking mechanism.

Excellent Theft Deterrence, Average Protection.Sep 19, 2010
By T. Shih
Over the years, I have used nearly a dozen different bicycle locks ranging from cables, U-locks, chains, and armored cables from a variety of different makes including Kryptonite, Planet Bike, and OnGuard. The truth is, a determined bicycle thief with the right tool and time on their hands will defeat any lock, but I've come to realize and appreciate that the relative level of protection a lock provides can be more important than the absolute protection. By absolute protection, I am referring to how difficult it would be to defeat a lock, and by relative protection, I'm talking about how secure your lock is compared to the measures employed by the bikes around yours. Thieves prefer to take the path of least resistance, so even if your bike were only parked upside down, it would be relatively better protected than an identical bike leaned against a post. (Obviously, if your bike is solitary or happens to be disproportionally attractive, expensive, etc, then relative protection is meaningless and you will have to rely on strong absolute protection and good locking methodology!)
Overall, the OnGuard Rottweiler 5026 is a well made lock that feels sturdy and definitely offers better protection than most traditional cables while still remaining reasonably portable. While it looks burly, keep in mind that it's the lightest of the armored cables sold by OnGuard and only has a ~15mm thick cable underneath the steel links. From a relative protection perspective, if the bikes you park next to are protected by cheap cable locks, the armored cable will be a fantastic deterrent. However, if the other bikes are protected by U-locks or big chains, watch out! Know that there are plenty of tougher locks under the sun, and that the Onguard Rottweiler 5026 is not particularly good in terms of absolute protection. (For reference, Kryptonite's New York Fahgettaboudit lock has an 18mm hardened steel shackle, and Kryptonite classifies its 25mm thick traditional cable lock as a mere theft deterrent!)
Personally, I use the Rottweiler 5026 as a secondary lock. I have a U-lock as my primary lock for the rear wheel + frame + immovable object, and non-quick release skewers for the front/rear wheels + seat post. I only use the Rottweiler 5026 to secure the front wheel + frame, or to lock my bike to things that are too big for my U-lock. In my application, I'm very happy with the OnGuard Rottweiler 5026, but then again I don't rely on it for primary protection. I've had generally good experiences with OnGuard locks and I will continue to use them in the future.
