Sports reviews of OnGuard Bulldog MINI DT 5015TC Bicycle U-Lock and Extra Security Cable

Customer Review: Nice little system!
Sport shop rating: 5 Stars

So upon becoming ridiculously attached to my first road bike, I decided to buy a decent locking system. I did a good amount of research and went with this little guy (also keeping funds in mind :)

It's worked great for me thus far. Sometimes I have to be a little picky as far as what I lock it to since it's a mini and the shackle is a bit smaller. However, I follow the Sheldon Brown locking system so I usually have no problem. Then I just loop the security cable through my front tire, then around what I'm locking to and then back to the lock. It's great!

Everything about the lock bracket is true though. It just feels really cheap to me. The last thing I want is to be riding around and have my lock falling off in the middle of a busy street. So I just toss the lock and cable in my bag. I've also put the lock on my frame while I ride and it's worked just as well.

Another thing I've noticed is that the crossbar only locks on the shackle one way. Sometimes I'll go to lock it and the key won't turn. So I just flip the crossbar over and it's fine. Not a big deal.

I definitely recommend this lock! It's perfect for the price. Or at least until you can save up for The Beast or a Kryptonite :)

Customer Review: Great little lock.
Sport shop rating: 5 Stars

I got this lock 2 years ago because I was going off to UC Davis (big bike town). Though mine did not come with the extra security cable, when I bought it at Mikes Bikes.

I like that it is small, it makes it potable, but still effective(if you are going to UC Davis, do not settle for just a cable lock, bike theft is the most reported crime in Davis.) I did not use the mounting accessor, I simply attach the lock between my frame and my support for a basket on the rear wheel.

I did break one key, but I broke the LED light, the key was perfectly functional. (The excess keys might seem like a lot, however, if you ever misplace your keys, it's nice to know you can grab one of the extras!)

The ONLY problem I have ever had with this lock is: the actual lock which is a piece of metal that is curved, and the bottom part fits into, slides. the metal piece slides down, making it difficult to slide the lock into place. This is why when you turn the key sometimes, it won't turn. SOME people might continue twisting with all their might and break the key. OR you could simply slide the metal piece back up, and it fits perfectly again. - This doesn't even happen that often, maybe once a month.

Customer Review: Great product for the price!

I've had this lock for a while and it still functions great. I use it to lock up my bike on the perilous grounds of a university campus and have yet to have a bike stolen.

I personally use the "Sheldon Brown" bike locking method, but a more general application involves locking the frame with the U lock and securing the wheels with the cable. Using the cable to secure the bike frame itself is not a viable means to protect your investments, as it can be cut rather easily. A u-lock on the other hand is hardened steel, which won't budge short of an angle grinder.

I'd also like to address the issues with the keys "breaking". Basically, the key will not turn and release from the lock until the U-shackle is securely and properly placed into the lock body. Therefore, the allegations of the locks being faulty and the keys being made of shoddy material are false. It arose from improper use of the product.

Overall, I really recommend this lock. It's a great value, but functions well and offers peace of mind.

Customer Review: Great lock
Sport shop rating: 5 Stars

I bought this lock because regular locks would not fit on our mountain bikes. The area between the crossbars was crowded with a waterbottle. This lock fits very nicely in the small area, and the extra cable is worth its weight in gold. I easily lock up my back tire to a pole and loop the cable through my front tire and the lock. It's a great little system. I also bought a bike seat storage pouch for the cable. It conveniently stores away there.

Many people said the holder was cheap when I read reviews. I don't agree with them. Mine works great and is very secure.

I had one complaint. The lock I received was not the one pictured. Mine has yellow ends on the locking bar. I think the modle number ended in TC, but I believe it is the same lock. It works great.

Customer Review: Haven't had to worry about whether its "theft-proof" or not.
Sport shop rating: 5 Stars

This lock looks sturdy enough and was really fairly priced. The cable lock is long enough to reach through my front wheel and back to my rear wheel where the u-lock is attached. I like that this lock came with so many keys, three + one with an LED light. I know a lot of the previous reviewers said that they're were "easily" breaking keys but i have yet to even come close to breaking one. I think if those reviewers READ THE INSTRUCTIONS, particularly where it says to put the key in until it clicks....THEN TURN, the keys would never break. I also like that Bulldog provides a sort of insurance with it, up to $1,501 according to their website [...] for this particular u-lock/cable combo. My intention is to use this lock for commuting back and forth to college.
