ABUS U-Lock Granit XPlus 540, Bike Lock with XPlus Cylinder, High Protection Against Theft, ABUS Security Level 15, Black/Grey

Seems like a solid enough lock. The real test is to see if somebody opens it and steels my bike.

Quality lock, but it is pretty heavy. Im using this as my commuter lock, and putting it in my backpack adds quite a bit of weight. However, good security comes at a price.

Heavy, but very Secure

Suddenly the key stopped working Luckily the bike wasn’t locked But lock components don’t move when key is turned

Very Nice!! Made in Germany, not China!!

This thing just rocks on so many levels. I feel confident using it at almost any location

It may be expensive, but so far totally worth it. Locks and unlocks like butter. Very sturdy. The holder it comes with to attach it to your bike frame is an awesome addition

Long enough for my scooter and a nearby post or rack. Beautiful mechanical sound when operated, makes me think of a bank vault door closing. Rubberized covering seems quite tough. Not terribly heavy but would make a fine defensive weapon should you happen to need one.

I can’t imagine anyone breaking this lock off. It would definitely be a challenge for the thief, and since most bike thieves are opportunists, I’m fairly confident a bike locked with this lock would not be their go-to to steal.
