OnGuard Pitbull Mini DT Shackle Lock with Cable

I bought this lock in November 2014 from Tredz and have used it ever since. It's a fantastic lock. Though I leave my bike outside every night, it has never been tampered with. I can't attest to how well it would resist an attempt but I think it certainly puts off any would-be thieves. The length is perfect, and only very very seldom I struggle to attach it to something secure. The shorted the lock - such as this - the better it's able to withstand attacks. The bracket is very secure once properly attached and the means by which you attach and release the lock from the bracket is very quick and easy. The keys fit into the barrel in either direction for convenience and the action is nice and smooth. After about 2 years of being left out every night, the locking mechanism began to get a little stiff but was quickly remedied by using some graphite powder. The bracket also showed signs of stress when I went to transfer it to a new bike after 3 years but Onguard quickly sent me out a new bracket totally free of charge. I can't recommend this lock enough and the company that produces it. Excellent all around. I can't comment on the cable element as I've never had to use it but if it's anything like the actual lock then it'll fantastic.

Very sturdy and excellent quality. Light-up key very useful as are the 4 spares. Too heavy to carry on bike but ideal for garage security and motorcycles.

Good value, good lock, good buy. I bought this lock in combination with another Abus to ensure I can secure the front and back. This is for the front, and represents good value - particularly in combination with a heavy Abus lock for the rear

Really pleased with this lock. It is well built and comes with 4 spare keys, the main key even has a light which is handy for dark mornings. The Gold Secure standard is reassuring and anti-theft guarantee good for insurance purposes. The only negative I would have is that it is quite heavy.

Really pleased with this lock as others have said the cable could be longer BUT I can loop it back on its self through one wheel round the frame and through the other wheel to get to the main shackle noo problem. The cable wraps tight around the shackle for transportation a bonus as mine came with a frame mount which is where it lives to and from the train station cable wrapped as well. Buy with confidence I'm buying another.

A fantastic lock solid even better than expected especially for the price. I will be spreading the word.

I was suprised at how solid this lock is and bigger than I thought it would be. Good build quality and excellent value for money.

Onguard pitbull lock & cable.As a mechanical engineer this is about as secure as you can make.

A good Dlock slightly on the short side for my liking but should do for most occasions. The cable is a bit of a let down though as it only just gets from front wheel to back wheel. Leaving little slack for going around any obstacles or having to only secure one wheel if you cant get the Dlock in optimum position.
