🔒 Premium Master Lock 8170D U-Lock Bike Lock – Keyed U-Lock 1 Pack, 6-1/8 in. Wide, Black Review

Nice castle. I use it to attach the front wheel to the frame, it takes 8 inches. The only flaw is that both pins have to be pressed at the same time. With my old U lock, you could attach the other end of the U to the bar and then lever it closed, which was much better. This lock tightens in that regard. The rest is good.

I've had this lock for about a year now with no problems. It lives on the straps of my backpack or on my bike. So far this is working very well. It should be noted that my bike is stowed inside and is only exposed to the weather outside. However, I am very happy with this lock considering the price.

Probably typical of U-locks. Very sure. Very difficult. Cannot get extra keys but comes with two. The mount is a joke. Will not fit on any of our 6 mountain bikes; You need thin tubing and a traditional large diamond frame. It might have worked on my old road bike, but it probably would have blocked the bottle cage. In fact, I prefer combination cable locks, but they are less secure.

Bought to prevent my front wheel from being stolen with quick release. There is already a crypto lock for the rear wheel and frame, I wanted something to send thieves to something simpler. This lock is VERY easy to cut if you plan to use it to secure the entire bike, don't do that!The lock works well but is not exposed to the edge elements and is stored internally.

Keys work fine, rained a lot but not rusty, just drain and add wd40. Ride. Didn't fall and didn't hit the spokes. One thing that bothered me since they LOOK like crypto locks, the U-bar points straight down on either side. This means that if you're used to a curved bar that's held at one end with one hand when locking, you'll need to hold the locking bar in a U to secure it with both hands. Used to it but still miss it. bend. Not only did this make locking easier, it actually holds the bike…

This lock has served me well in the few months that I have had it. Time will tell if a bike thief tries to break it? This isn't a premium lock that can cost over $100, but it's very good value for money. If you are looking for an inexpensive lock that seems to work well enough then I would recommend this one. One important comment: the picture on the picture on Amazon is different from what I received. The one I received has some sort of heat sealable rubber backing while the Revain image…

scrap. Initially I was pleased with this product until, like many other buyers, the lock would not open about a week after purchase. It all started with the key being a bit difficult to turn and a little wiggling would help. Well, it quickly became apparent that the pins were so difficult to get into place that the key nearly broke no matter what I did to shake and push them into place. This happened every time I tried to unlock my bike. The last time I used it I thought I'd have to call…
