ABUSU-lock Granit XPlus 540 - Bike lock with XPlus cylinder - security level 15 - Black/grey

Summary, an excellent strong lock and you will not find anything stronger.This model is p/n 111792 which is the 300 mm reach model without any bike bracket/holder.There are 6 models manufactured by Abus, some with a 230 mm reach and there are two types of bike bracket/holder, the EaZyKF and the USH540 . Thus in the 300 mm reach models you can have without a bike bracket/holder OR with either of two bike bracket/holders. The same with the 230 mm reach models.EaZy KF – Bracket with comfortable one hand operation for easy mounting on round frames with a diameter of 28-36 mmUSH 540 – Universal bracket with easy mounting on round frames with a diameter of 15-35 mmThis review, and the one I purchased, being the 300 mm reach without a bike bracket holder.IMPORTANT to note that this is the latest model 540, there was also a model 54, but if you check the forums and reviews this 54 model had problems with some cosmetic plastic pieces that could be knocked off if you dropped the lock.For the best security you cannot better this lock, and it is rated Gold Secure with a security level of 15 which is the highest that I have seen for any bike lock.Made and designed in Germany by one of the biggest manufacturer of locks.Comes with two keys, one of which has a LED light. Also supplied is a ‘Code Card’ which would enable the owner to order more keys or replace one upon proof of ownership or purchase.On the negative comments I can only list its weight and cost, but then you buy a bike lock like this for the best security. You will not get ultimate security and strength without weight and this of course must cost more. Frankly my bike is worth the expense, plus the inconvenience of making an insurance claim, getting paid and then trying to buy another bike….. Better to lock it securely with a lock like this.

Good size, so easy to attach my expensive e-bike to bike racks and street furniture.Very sturdy, giving great confidence in my bike's security.The led light in one of the keys is a nice touch.I strongly recommend it if keeping your bike is important to you.

Best bike lock available

I bought the version with two keys and quick release mount and long shackle. The q/r mount feels sturdy and well made, but is it really necessary? Why do you ever need to take it off the bike one handed? You always need to use two hands to unlock it before use anyway!A spare key bought later is very expensive so I am pleased to have two.Main issue is that it does rattle (between the shackle and the 'locking bar') whenever the road is a bit rough and this might annoy some people - it is a quiet rattle but still noticeable. The non-q/r mounting bracket might hold it all together better and stop the rattlingIt is a chunky lock and hopefully will dissuade would be thievesInstructions could be clearer

Seems sturdy

Ot does everything it should. Easy to push on, turn of the key and you are done. Why buy any other (decent make), when you can have ofthese. It is German, not made in China. When you average out its cost over just a few years, it is worth it.

Bought for my son really good product definitely recommend

Good size. Bought to go through motorbike wheel and lock to swing arm. Fits perfectly. Really thick. Double locking arms so have to cut through both to break. Obviously nothing stops an angle grinder but this certainly makes the knobs look for an easier target.
