OnGuard Pitbull Mini DT-8008 Bike Lock, Keyed Shackle Locks, High Security & Reliable, Lock With Co-Moulded Crossbar, Locks Shackle On Four Sides, Hardened Steel Cycle Lock, Black, 9.0x14.0 cm

If I could take back all the stars I have given to all the products I've bought from Amazon to give to this, I would. It's a stunning piece of kit, one of the highest rated locks, really well put together and combined with a beautifully supple steel cable to lock the front wheel while the D lock secures the rear to the frame. This is smaller than many others in the range, making it much more manageable and light. It even has a proper tethering mechanism to secure it safely to the frame without fear of coming loose or scratching the paintwork. I bought its big brother in error but will keep it for more permanent fixing.. or challenging David Blain to a serious contest. You simply could not ask for a better security system for your bicycle

These are nice locks and I have two of them but I can't register keys or theft program which was one of the reasons for buying them. You do get 5 keys but the registration is limited to USA and they say contact the distributor !! If you don't care about registration then yeah, buy these locks, they fit tight enough to the bike to make breaking them difficult. But if your like me ... stay away and look for a brand that really is international and can support more than the USA.

Very good quality lock easy to unlock and lock back up just the right size nice amount of room to fix to a bycycle post but not too small but wouldn't be able to lock two bikes up on a post together it fits just right in my frame I have a 18" frame and it fits nice in there it was easy to install the fixing braket only took 10 minutes get 5 keys one with a light on it so that will come in handy

I have the larger Onguard locks, so wanted something smaller and lighter as it does not make sense to spend money on a light framed bike and then go buy a few Kilos worth of a lock to lug around make the whole bike feel much heavier.It's a good solid looking lock. I can't feel a massive difference between the larger Onguard locks and this smaller one in terms of weight. But understandably as the metal is 14mm thick to make it resistant to cutting, it probably needs a lot of hard metal. The cross bar looks about the same size as in my other Onguard locks.Recommended for the security but only if you don't mind the heavy weight.

A great little lock which does the trick. As it is Diamond rated it's suitable for my insurance cover taking value if my ebike into consideration. The wire that comes with it is long enough to feed through both wheels and then back into the lock. Tip: feed one end of the rope through the other end once you feed it through either wheel and then it is long enough to feed through the other wheel and onto the lock itself ensuring both wheels and frame are secure.It is quite heavy for its size so if you intend to carry it with you on your person be mindful that you will know that it's there in a backpack or similar. Works well with the key provided. Slight issue is that to lock it the key needs to be turned and it won't lock if key is not present.

I'm probably not the usual customer for this becuase I use it to lock our driveway gate rather than a bike. It's still a great buy. I used to have a (slightly, £15) cheaper D lock and the quality and build of this Pitbull is a massive improvement in security. The chunky looks and "Sold Secure Gold" marking is probably sufficient to put off the casual ne'er do well, and it looks like it would be no push-over for the 18" bolt cutter in my tool box.One point to note: one of the arms has a protrusion moulded on it (not shown in the product listing photo), which could be a problem if you're intending to use the lock through a narrow gap.Recommend.

Makes for a perfect second U-lock for me and my needs! Might be a bit on the small side to properly lock a bike through the rear triangle and wheel so please take this into account if you want this for you're main lock and want to lock you're bike properly. The standard size of this lock will be you're choice if that's the case!Having had a bike stolen recently, this time around I wanted to do things properly. I use this to lock my front wheel to my frame in conjunction with a OnGuard Brute to secure my bike and rear wheel. The cable is perfect for connecting both locks and keeping my saddle tied down. I now feel a lot more confident about leaving my bike around town.As for the lock, really nice build quality, hefty but without the weight of my Brute. Love the look On-Guard have gone for in the newer locks. Really stands out and makes a statement to any wandering eyes. I personally throw my locks in my bag when I take them with me so can't comment about the mounting bracket but seems hefty enough. The LED light key is another lovely touch and there's plenty more conventional keys includedSold secure gold rating for a product 1/3 the price of the competition...Buy with confidence!

Good for the price, very small though, so small unusable in bike rack, only useful if you plan on locking your bike to a pole.People have said that the lock fails sometimes, if you leave it in the rain WD40 should stop the lock rusting or freezing, occasionally oil with bike oil, good product for the money if you plan on locking your bike to a pole, light and easy to transport.
