OnGuard Bulldog MINI DT 5015TC Bicycle U Lock and Extra Security Cable – Reviews

I have had this lock for a couple months now, and am very happy with it. I agree with others who say that the key is a little funky sometimes, but in practice, I’ve been careful not to force it, and have had no problems. I also use the Sheldon Brown method, though on my road bike, I can fit the U around my rear tire + the frame and bike rack, and still loop the cable to the front tire. I don’t bother with the bracket, I carry the lock either in a bag, or simply with the cable slung over my back like a shoulder bag.

In terms of its utility there is nothing wrong with this lock. It’s a nice balance of size, weight, and security. However, after a couple of days use I really missed my Kryptonite. It seemed better engineered in all respects. Most importantly, I would get stuck wrestling with this lock while locking/unlocking it. If it is not very firmly in place (it is more difficult to tell than with a Kryptonite, because the Kryptonite has the hook on one side of the bar to help keep it in the locking mechanism), you can’t lock it; because the keys feel flimsy, I am worried about breaking or bending them. The keys are also much larger than the Kryptonite ceramic style, and I appreciate the minimalism of the latter (plus they are made of metal). Lastly, the frame brace places the lock slightly beside the frame, where it is guaranteed to rub against your leg while riding. I also seem to be smashing my fingers between the lock and frame trying to insert and remove it from the brace — granted

I bought this item for my freshmen year at college. It broke in about a month. The key got jammed TWICE! The first time I was able to dislodge it, and just had to use a new key, but the second time I wasn’t able to get it out, and a maintenance crew member ended up breaking my key in half! This product is cheap. Pass it up.

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
