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

By and far probably the best lock out there. BUT, the key is starting to be sketchy, after a year or so. Im worried one of these days itll just get stuck completely and my bike will be trapped.

Theres no foolproof or thief proof lock. Theres no foolproof or thief proof lock. Theres no foolproof or thief proof lock. This one is pretty close to both (just dont lose your key, fool).

IMO the right combination of size and weight, but you’ll have to be against the bike rack to lock the frame to the rack. Barely fits inside my bike trunk, but worth it. I would recommend the locking dock attachment if you have space to store it within the frame.

Ive been a Kryptonite user for years, and I still am. I think they make great locks, very sturdy and intimidating in that they pose some difficulty to a thief, enough to be a deterrent. However, they dont perform well over time. They dont like being outside for long periods of time, which is understandable. They stick, and eventually it was taking me several minutes to get my yellow NY U-lock unlocked. No amount of maintenance would help. So I got this thing. Its great. It stays outside with my bike in all weather and it works. Silky smooth. And its just as strong if not stronger than the Kryptonite equivalent. I love it. Its expensive, but you might have to buy it only once if you only keep one bike outside.

I definitely take comfort in knowing I have the hardest lock to break on the rack. Highly recommenced if you can get it for the right price.

It gives me the comfort to run into a store for a few minutes with my OneWheel mounted to my soft top Jeep.

I did a lot of research on bike locks before choosing this one. This is one of the highest rated locks (of the other two, one weighs a ton and the other is almost $300). It was number one against lock picking and its extremely resistant to a grinder with a titanium blade in spite of its 16mm shackle. Never mind bolt cutters. Its designed to resist extreme torque as well. Its easy to mount and rests sturdy. No rattling. Besides its amazing strengths, its relatively light in weight. This is my main lock. Although, I obviously dont rely on only one lock. The other is its rival in the same category. The other weighs a ton, tough.

great product

Turning the key is butter-smooth. Seriously secure lock.

Great
