OnGuard Pitbull U-Lock: Protect Yourself from STD Theft

Ricardo: Tranca excelente por certamente ser muito segura. Bem pesada e grande.

Alejandro D.: El candado es de muy alta seguridad ahora bien, viene justo de engrase y más vale que lo aceites de vez en cuando porque después de unas lluvias puedes verte con una bici que no puedes desencadenar, y este no lo cortas con ninguna cizalla. Repetiré

zaboo: Este candado U-Lock es la mejor opcion de un nivel de seguridad 8/10, y al mejor precio que encontraran en plataformas digitales.

En definitiva es una de las mejores 3 marcas en candados U-Lock, quiza no es de calidad excelsa como lo es Kryptonite o Abus, pero la funcion de seguridad es muy buena y bastante confiable.

Apesar que algunos de los materiales se ven que duraran menos tiempo, un buen cuidado podria extender la vida util al igual que las marcas previas que son de mejor gama.

Adicional, les sugiero que la inversión del candado ronde entre 30-50% del valor de su bicicleta, en mi caso no quise invertir mas en uno de calidad superior o nivel 10/10 ya que el candado superaría mas del 50% de costo sobre el valor de mi bicicleta.

Siempre se recomienda combinar el uso de este candado con algun otro U-Lock, Cadena o Cable de Acero de menor calidad (nivel de seguridad 2-4/10).
(Si es cadena que al menos sea de 1/2 de pulgada de grosor, y con un candado de al menos 50mm y llave de alta seguridad.)

Michael S.: Overall I'm very happy with it, especially for the dual bar lock system. I did extensive research on locks and came to the conclusion that this is the most secure for its security grade, and for the price point. Even more than other higher security grade well-known name ones. The only thing I don't like is the plastic shell on the lock itself, it feels and looks flimsy. But no problems so far. The lock system is very smooth and easy to use, I like how slim the key is, and love the auto-shut cover on the keyhole to protect it from water or dust. The carrying saddle for the lock is easy to use as well, however, would be better if not plastic. The U bar is wide enough to fit both my front wheel and the frame, even through one of the paddles onto any thick bar/bike lock, this method adds extra annoyance and could deter thieves ( recommanded by police). Bike thieves suck, good luck folks

jivor50: Great lock, easy to lock and unlock. It is big and fairly long however it just missed being able to get my front tire and frame (24 inch) together on same lock so I had to go with the frame when I purchased this for an event. Luckily the event customers were very nice and didn't take my front tire but I didn't expect that to happen either. It does come with a bike mountable holder which is nice and it keeps the lock securely in place when riding. It seems very thick and should take someone a bit of time to try and hack through so for the money spent i think it is great value on a fairly heavy duty lock, I would buy again at this point.

T: Very hefty, solid lock. It looks quite nice too. One small problem is that the thick base plate part is so chunky that if I mount it on the saddle, it gets in the way of my thigh when pedalling. I've had to move it down to the main frame of the bike, and there is pretty much only one option in terms of positioning where it won't rub against my legs, so the placement is not very customizable for my bike anyway.
I haven't had any problems with the lock sticking as yet in the few months I've owned it. I sprayed a bit of silicone oil into the lock when I first received it. The size is perfect for going through the frame and wheel of the bike and around a signpost. Not much wiggle room left after that. The smaller version would have been too small, and the longer version should be good for 2 bikes or for locking your bike to a lamppost. I pair this with a kryptonite 7' cable to secure my front wheel and saddle as well. The 4' cable would have been far too short for this.
One other thing that annoys me is the quick release. The part of it which clamps onto the U lock and allows you to attach it to your bike always works loose so when I try to just snap...

Jay C: NYC is a high criminals areas, and the school i go to was next to the black neighborhood.
so i got 3 bikes stolen in total!!! i was so pissed off!!!!
eventually i decided to buy a better lock to guaranteed my bike won't get stolen again.
so my 4th bike i bought this lock and it works like a charm!
one day after work, i felt like the position of my bike was altered!!
when i ran and check what happened, i saw there were sign of light cutting marks on the shackle.
so this lock survived the lockpick!!

the lock is pretty good! thick shackle and steel is very strong!! i saw a video that wire cutter breaks for cutter the shackle!
if you have an expensive bike, you should at least buy 2 locks though

Tony M.: Locks are simple tools that need to do a few things perfectly. So far this lock has prevented my bike from being stolen, so that's a nod to its credibility. What's important to me is that the shackle opens and shuts reliably. In this case the OnGuard is flawless. I open and close my lock 10 times a day as I'm running errands, arriving at work etc. I've had other locks that were a pain to open & close. This lock has a solid tumbler & shackle that operate cleanly. And when it gums up I just squirt some WD40 (as suggested by the owners manual). Moreover, each lock includes 5 spare keys and a tag to allow you order replacements. You can tell these guys know their stuff.

M. Butler: Ordered this because it looked tougher than the other U-locks that can be had for $10-40. It might take a minute or two with an angle grinder (not verified) but it'll deter thieves with hacksaws and bolt cutters. Comes with a mounting clip that is screw on, not flimsy like the others that have a pull-tight mount. Comes with 5 keys (1 big, 4 small) which is nice but unnecessary for my use. I use this to lock my bike in the back of my truck (with a cable) and on campus. Easier to use than those circle-wound cable locks, and quite a bit more secure. On campus, this fits through the rear of the frame and rear wheel, securing all but the front wheel of my bike. This won't fit around your seat tube and rear wheel, you'll need something bigger for that. Great value for the price, I'd recommend this lock to any bike owner.
