Enhanced ABUS Ultra 410 Bike U-Lock: Boosted Security and Durability Review

Nice lock and I would keep it if they sent me the right one. Selecting black shows black and light green, selecting black/lime shows all black. I assumed that the choice was more correct than in the picture ... I ordered black and received black and light green. Very annoying! Good product, bad logistics.

Really nice lock. Love the fact that I don't twitch and twitch to open it like my previous kryptonite lock which stopped opening and I couldn't open it. If you plan on leaving your bike overnight, you may need something stronger. Asus men are really good stuff. I liked my lock so much I bought their mini. This is my current lock.

This is a great lock and the size eliminates the need for a long cable unless you need to lock both hoops. I had wheel locks so I didn't have to worry, and it was easy to install around posts, trellis, fences and more. The plastic bike mount is a bit flimsy, so I recommend replacing the plastic mount with a metal kryptonite mount. It's just as good and much cheaper than a kryptonite lock, even when purchasing a bike rack.

I use this lock when I'm cycling around town and I need more protection than the usual cheap locks. I like this larger size as I can lock my bike's frame and turn on my friend's frame. I use a different longer lock for the front wheels. I felt completely safe leaving my new bike locked with this U-lock. It's very heavy and durable, but I could still put it in my backpack and ride 15 miles without even noticing it. Then when we stopped to eat I just pulled it out of my backpack and put it on. I…

Exactly what I was looking for, not very heavy but very strong. Opening and closing this lock is easy. The lock is qualitatively and thoughtfully manufactured. I initially had trouble mounting it on the bike because of the water bottle holder, but the mounting ring allows it to be mounted on the rear fork where it's out of the way. Of course, this lock has no lock. 15-star safety rating (safety rating = 8) like the more expensive models, but the price and quality are hard to beat. In any case…

I bought this lock to use on my bike for commuting and I use it when I have to commute downtown for small tasks, usually up to an hour. Safety-wise so far so good. However, if I had to leave the bike outside for a long period of time (i.e. a normal work shift), I would probably choose a more durable model. The main disadvantage of this lock is that it is inconvenient to carry. An attachment to the rear triangle, for example, is not possible. To put it on the bike frame I had to take out one of…

So far so good! The Abus bike lock appears to be secure, but has not yet been "tested" against real bike thieves. I had a Kryptonite bike lock a while back and I definitely saw someone try to pick that lock (the rubber band on the end of the lock was cut but not the metal part of the lock). Abus Castle is intact today, so as far as I can tell there have been no attempted break-ins. I really like the size of this particular model as it also allows me to mount my rear wheel. No excess is left for
