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

Slick to use. Hefty look would definitely put off anyone wanting to Nick my bike

This lock was very expensive and only worked for 3 months!!

Sturdy and locks well. Note weirdly does not come with bracket to attach to bike which is pretty annoying.

The ABUS lock itself is great; I've used them for years. However, Amazon advertises "Delivery includes: 2 keys (one of which is an illuminated key)" and includes product imagery of the larger illuminated key along with the smaller 'backup' key. I've always got both large and small keys when buying these locks before. However in this case Amazon included only two smaller backup keys with our order.

This 23 cm Abus lock costs more here than with other sellers, and actually comes with less, i.e. there is no supplied mounting bracket. What's not to like?

Bought to secure my Vespa as old D-Lock had broken. It's not the cheapest but also not the one that will melt an angle grinder disk. It seems like it's the best at it's price point and having used it for a month, it seems decent enough.
