Review: I still have my bike, so it works!
Review: When I first received this package and I felt how heavy this Item was, I wasn't really sure what it was But when I opened the box to see this lock I was Impressed on how Heavy Duty this lock was. It will definitely slow someone down trying to steal your bike, if they even want to bother to try after checking it out. I'd highly recommend this lock! Now when you store the cable I found a way to connect the bracket to the up riser where your seat post sets in. The bracket was to small to fit around the riser on my bike but I had enough room to put it around the riser without breaking it and then I put zip ties through the screw holes along with one under the bracket to support bracket to the riser itself. This helps for when you go to pull the locking post from the bracket It won't slide down. The way I tie the cable is by just wrapping the cable to the cross member about 4 times around and then I put the U-Lock through the eyelets on the cable and this holds the cable on pretty good. I have the U-Lock set up so the bracket is facing the front of the bike, so when you put the U-Lock in the locking post this to is facing the front of the bike. I have not had any problems with the U-Lock and cable interfering with my peddling. I hope this kinda helps people out on how to mount the bracket and attach the cable and lock together.
