## Description

The OnGuard Pitbull STD U-Lock offers serious protection for cyclists in medium-to-high-risk areas. Its 14 mm hardened-steel shackle and X4P Quad Lock Mechanism secure the shackle on four sides to resist cutting, twisting, or prying. With a 290 mm TriRadius design, it easily fits around racks and posts while maintaining strength and compactness. Rubber-coated surfaces prevent scratches on frames, and the included mount bracket ensures convenient carrying. Comes with five laser-cut keys (one with LED light) for visibility and reliability during night use. Designed for riders who demand professional-grade security and everyday usability.

Review: Great Lock - 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.
Review: Good value lock. - 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.

### ⭐⭐⭐⭐⭐ Great Lock

### ⭐⭐⭐⭐⭐ Good value lock.

### ⭐⭐⭐⭐ Heavy duty lock
*by J***. on June 6, 2013*

This thing is quite large and as another reviewer has mentioned, comes in toy truck colors. That being said however, this U-Lock is sturdy and definitely won't be easy to crack. I live in LA County so I need a lock that'll at least save my bike frame(and hopefully more...) One amazing reason to get this lock in particular? It comes with a mount for the lock. You can just snap it in place on your bike and not have a bag to lug it around in- I'm using this feature on a colnago road bike,so it should work on most bikes. I have trouble sometimes putting the U lock back into place onto the bike mount, this might be an error of placement on my part though. Overall I'd give this 3.5-4 stars, and below are the reasons why: Pros: Heavy duty, bike mount, several keys, large frame for bigger poles Cons: Heavy, no selection of colors, bike mount could be better, price
